2 X + 3 Y=_ 4
_ 5 x + 4 Y + 13 =0
X = -10
Y = 8
2 X + 3 Y = 4 ---- (i)
5 X + 4 Y + 13 = 0 ---- (ii)
rearranging eqn (ii), we have
5X + 4Y = -13 ----- (ii)
multiply eqn (i) by 5 and eqn (ii) by 2
10X + 15Y = 20 ---- (iii)
10X + 8Y = -26 ---- (iv)
subtracting eqn (iv) from (iii), we have
10X - 10X + 15Y - 8Y = 20 - (-26)
0 + 7Y = 20 + 26
7Y = 56
Y = 56/7
Y = 8
Substituting Y into eqn (i), we have
2X + 3Y = 4
2X + 3(8) = 4
2X + 24 = 4
2X = 4 - 24
2X = -20
X = -20/2
X = -10

The rate (in mg carbon/m3/h) at which photosynthesis takes place for a species of phytoplankton is modeled by the function P = 80I I2 + I + 9 where I is the light intensity (measured in thousands of foot-candles). For what light intensity is P a maximum?
Answer:
At ; I = 3, P is at maximum
Step-by-step explanation:
P ( I ) = [tex][ \frac{80 I}{I^2 + I + g } ][/tex]
at I = 3
P" ( I ) < 0
therefore at I = 3 the value of P( I ) is at maximum

This is solving multiple step equations
Answer:
x=-11/3
Step-by-step explanation:
expand the brackets: 4x+12= 1
this is now a normal equation
solve the equation
-12 from both sides
4x=-11
divide by 4 both sides
x= -11/4
this is because 11 cannot be divided by 4 exactly so we put it in fraction form .
9 Helen measures a rectangular sheet of paper as 197 mm by 210 mm, each correct to the nearest
millimetre. Calculate the upper bound for the perimeter of the sheet of paper.
Answer:
Perimeter of the sheet of paper = 814 mm²
Step-by-step explanation:
Given:
Length of side = 197 mm
Width of side = 210 mm
Find:
Perimeter of the sheet of paper
Computation:
Perimeter of the sheet of paper = 2[l+b]
Perimeter of the sheet of paper = 2[197+210]
Perimeter of the sheet of paper = 814 mm²
Given that sin x = 3/4
where x is an obtuse angle, find the exact value of cos x.
Answer:
Step-by-step explanation:
sin x =3/4
x is an obtuse angle and sin x is positive .
∴ x lies in 2nd quadrant.
Hence cos x is negative.
[tex]cos x=-\sqrt{1-sin^2x} =-\sqrt{1-(3/4)^2} =-\sqrt{1-\frac{9}{16} } =-\sqrt{\frac{7}{16} } =-\frac{\sqrt{7} }{4}[/tex]
Solving a trigonometric equation, it is found that:
[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]
The sine and the cosine of an angle x are related by the following equation:
[tex]\sin^2{x} + \cos^2{x} = 1[/tex]
In this problem:
x is an obtuse angle, which means that it is the second quadrant, in which the sine is positive and the cosine is negative.[tex]\sin{x} = \frac{3}{4}[/tex], thus:
[tex]\sin^2{x} + \cos^2{x} = 1[/tex]
[tex](\frac{3}{4})^2 + \cos^2{x} = 1[/tex]
[tex]\frac{9}{16} + \cos^2{x} = 1[/tex]
[tex]\cos^2{x} = 1 - \frac{9}{16}[/tex]
[tex]\cos^2{x} = \frac{7}{16}[/tex]
[tex]\cos{x} = \pm \sqrt{\frac{7}{16}}[/tex]
Since the cosine is negative.
[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]

Answer:
x=9
Step-by-step explanation:
First you have to identify the black line at the bottom so it means it's 180 degrees. No notice the red box it means it's 90 degrees. We can conclude from this that the other side of the red box should also equal 90 degrees. So to find x you have to set up this equation: 6x+4+32=90. Then you solve for x which ends up being 9.
If you liked my answer then please make it the brainliest it would be much appreciated. Thanks!
Answer:
The x would be 9
Step-by-step explanation:
9 times 6 equals 54 plus 4 equals 58

Lets define a=1st number, b=2nd number, and c=3rd number
We know that a+b+c=126
We also know that the second number is 6 more than the first, so we can represent this as b=a+6
We also know that the third number is 3 times the first which can be represented as c=3a
We can plug these new values into our original equation and get:
a+(a+6)+(3a)=126
2a+6+3a=126 COMBINE LIKE TERMS
5a+6=126
5a=120
a=24
Our first number is 24.
Our second number is 6 more than our first number, so the second number is 24+6=30
Our third number is 3 times the first number, so the third number is 3(24)=72
We can check by plugging these numbers in for a, b, and c in our original equation
a+b+c=126
24+30=72=126
126=126
The numbers are 26, 20, and 80.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Three numbers:
First = a
Second = b
Third = c
Now,
a + b + c = 126 ____(1)
c = 4b ____(2)
b = a - 6 _____(3)
From (1), (2), and (3) we get,
a + (a - 6) + 4b = 126
a + a - 6 + 4b = 126
2a + 4b = 126 + 6
2a + 4b = 132
2a + 4(a - 6) = 132
2a + 4a - 24 = 132
6a = 132 + 24
6a = 156
a = 26
Now,
a = 26
b = a - 6 = 20
c = 4b = 4 x 20 = 80
Thus,
The numbers are 26, 20, and 80.

Tammy sold a diamond ring for $10,000. She placed the money into a CD with a 3.9% interest rate compounded
annually. What is the interest earned on the amount after 4 years?
a.)$1653.66
b.)$1984.87
c.)$1492.04
d.)$1119.99
=====================================================
Work Shown:
Use the compound interest formula
A = P*(1+r/n)^(n*t)
A = 10000(1+0.039/1)^(1*4)
A = 11,653.65589441
A = 11,653.66
That's the amount of money Tammy will have at the end of 4 years.
Subtract off the principal from this value to get the interest.
interest = A - P
interest = 11,653.66 - 10,000
interest = 1,653.66

A shipping company claims that 90% of its packages are delivered on time. Jenny noticed that out of the last 10 packages shipped, 2 were late. What is the probability that 2 out of 10 randomly selected shipments would be late?
Answer:
The probability is;
0.0000003645
Step-by-step explanation:
The probability of packages being early p is 90% = 0.9
The probability of packages being late q will be 1-p = 1-0.9 = 0.1
So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem
That will be;

Christian is rewriting an expression of the form y = ax2 + bx + c in the form y = a(x – h)2 + k. Which of the following must be true?
Answer:
The Value Remains the Same
Step-by-step explanation:
Trust
The value of a remains unchanged. Therefore, option C is the correct answer.
Given that, Christian is rewriting an expression of the form y = ax² + bx + c in the form y = a(x – h)² + k.
We need to find from the option which is true for the given statement.
What is a vertex form?The Vertex formula of a parabola is used to find the coordinates of the point where the parabola crosses its axis of symmetry. The vertex is the point (h,k). As we know the standard equation of a parabola is y = ax²+bx+c. The vertex form of the parabola y = a(x - h)²+ k. There are two ways in which we can determine the vertex (h, k).
Now,
The original expression is given as y = ax²+bx+c and Christian rewritten as y = a(x - h)²+ k.
Simplify the equation y = a(x - h)²+ k, that is y = a(x²-2xh+h²)+k.
⇒y=ax²-2axh+ah²+k
Compare the equation y=ax²-2axh+ah²+k with y = ax²+bx+c.
That is ax²=ax²
bx=-2xh and c=ah²+k
Analyzing the above equations ax²=ax²
Now, divide both sides by x², and we get a=a.
So, the value of a remains unchanged.
Therefore, option C is the correct answer.

Si se desea que el jugo mixto contenga un 10% de jugo natural, ¿Cuántos litros de cada preparado se deben emplear?
Answer:
El administrador debe usar 37.5 litros de jugo al 5% y 12.5 litros de jugo al 25%.
Step-by-step explanation:

Llamamos:
x = litros de jugo al 5% natural
y = litros de jugo al 25% natural
El administrador de la cafetería desea hacer 50 litros de jugo, luego:
x + y = 50 [1]
Esos 50 litros de jugo deben tener 10% de jugo natural. Como cada parte de x aporta 5% y cada parte de y aporta 25%:
5x + 25y = 10*50 = 500
Dividimos entre 5:
x + 5y = 100 [2]
Restamos [2] menos [1]:
4y = 50
y = 50/4 = 12.5
De [1] tenemos que:

15. Write the slope-intercept form of the line described in the following:
Parallel to 3x + y=5
and passing through (2, 3)
Answer:
Step-by-step explanation:
We know that parallel line must have the same slope
First we change the given equation to slope intercept form y =mx +b
From 3x+y=5 ( we need to find the new y intercept using the given x and y values of (2,3)
find for y by subtracting 3x from both sides of the equation
3x +y = 5 -3x-3x
we get : y = -3x +5
Use the x and y values given (2,3) and substitute in the equation above
to find find for b (remember we need a new y intercept..b)y = -3x + b
3 = -3(2) + b
3 = -6 + b
b = 6 = 3
b = 9
The new equation that's parallel to the given equation would be
y = -3x + 9

simplify by dividing [ -3/-8] divided by 5/9 (5 points)
A. -15/-72
B. 15/72
C. -27/-40
D. 27/40
Answer: D
Step-by-step explanation:
(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.
I think C was supposed to be -27/40 so D is the correct answer since it's positive.
