x+ y + z = -3
3y - Z = 4
2x- y - 2z = -5
Answer:
(-3, 1, -1)Step-by-step explanation:
x + y + z = -3 --> (1) 3y - z = 4 --> (2)2x - y - 2z = -5 --> (3)Add up (1) and (2)
x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1 --> (4)Double (2) and subtract from (3)
2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 82x - 7y = -13 --> (5)Double (4) and subtract (5)
2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1Finding x
x + 4(1) = 1 ⇒ x = 1 - 4 ⇒ x = -3Finding z
-3 + 1 + z = -3 ⇒ z = -1So the answer is:
(-3, 1, -1)8/6+(-9/5) . . . . . . . .. .. . .. . . . .. . .. .

what fractions of the second ten counting numbers (11,12,13...,.18,19,20) Are composite and prime
will be the brainest
Answer:
Fraction of composite numbers = 6/10
Fraction of prime numbers = 4/10
Step-by-step explanation:
A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.
Thus, it means that the set of numbers given to us which is;
(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;
12, 14, 15, 16, 18, 20
This is because each of them have at least one divisor that is neither itself or 1.
Thus, we have 6 out of the 10 numbers as composite.
Fraction of composite numbers = 6/10
Now, a prime number is a number that are only divisible by itself and 1.
Thus,from the given set, the prime numbers are; 11, 13, 17 & 19
We have 4 out of 10 numbers as prime numbers.
Thus, fraction of prime numbers = 4/10
An insect population is growing at a rate of 2t/8 insects per day. Find the size of the insect population after 24 days assuming that there are 100 insects at time t=0.
Answer:
244
Step-by-step explanation:
Number of insects at time [tex]t[/tex] = 0 are 100.
Rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day
Time, Number of days = 24 days
To find:
Number of insects or size of insect population after 24 days.
Solution:
Given that rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day
We are given that, [tex]t[/tex] = 24 days
Rate of growth =
[tex]\dfrac{2\times 24}{8} = 2\times 3 = 6[/tex]
Growth in Insect population after 24 days = [tex]24\times 6 = 144[/tex]
Initial population = 100
Therefore, the answer is:
The size of insect population after 24 days = 100 + 144 = 244

Is 16.4 greater than 16
Answer:
yea
Step-by-step explanation:
Yes.
16 could also be written as 16.0, or 16.00 or even 16.00000.
16.4 could also be written as 16.40, or 16.400.
And of course, you know 4 is greater than 0.
This is why 16.4 is greater.
When you add a decimal to a number, it always makes it larger. its like saying 16 and 4 tenths.

Answer:
2 3/8
Step-by-step explanation:
-7 1/8 = -(7*8 + 1) / 8 = -57/8
-9 1/2 = - (9*2 + 1) / 2 = - 19/2
simplifying
= -57/8 - (-19/2)
= -57/8 + 19/2
= lcm of 2 ,8 is 8
= (-57 + 4*19) / 8
= (-57 + 76) / 8
= 19 / 8 ------> (19 = 8*2 + 3)
= 2 3/8

The Equation of parallel line is y= 3/7 x - 2/7.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We have equation 3x – 4y = 7 and passes through (-4, -2).
Writing the given equation in slope intercept form as
3x = 7 +4y
4y = 3x- 7
y= 3/7 x - 4/7
so, the slope of parallel line is 3/7.
and, passes through (-4, -2).
y= 3/7 x +b
-2 = 3/7(-4) +b
-2 = -12 /7 + b
b = -2/7
So, the Equation of line is y= 3/7 x - 2/7.

What is the solution to the inequality f + 4 < 2?

f < -2
Step-by-step explanation:
Write down in terms of n, an expression for the nth term
of the following sequences
a) 25 20 15 10 5
Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
Answer:
The nth term will be:
[tex]a_n=-5n+30[/tex]
Step-by-step explanation:
Given the sequence
25, 20, 15, 10, 5
An Arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Computing the common difference of all the adjacent terms
[tex]25,\:20,\:15,\:10,\:5[/tex]
[tex]20-25=-5,\:\quad \:15-20=-5,\:\quad \:10-15=-5,\:\quad \:5-10=-5[/tex]
As the difference between all the adjacent terms is the same and equal to
[tex]d=-5[/tex]
Also, the first term is:
[tex]a_1=25[/tex]
Hence, the nth term will be:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=-5\left(n-1\right)+25[/tex] ∵ [tex]a_1=25[/tex], [tex]d=-5[/tex]
[tex]a_n=-5n+30[/tex]
Therefore, the nth term will be:
[tex]a_n=-5n+30[/tex]
A bakery made 9 cakes using 3 bags of flour. The bakery uses the same relationship between cakes made and the amount of flour used to make all of their cakes. Which table of values shows the relationship between the number of cakes the bakery makes to the number of bags of flours the bakery uses?
Answer:
c = 3b
Step-by-step explanation:
9 cakes proportional to 3 bags of flower
cake = k(bag)
c = kb
9 = k(3)
k = 3
c = 3b
you didn't send any table of values but this is the relationship between the cakes and flour, you can use it.

which represents an even function?
y=cos(x)
I think the one that represents a even function is cos(x)
Answer:
The cosine is an even function which means that if (x,y) is on the graph of the function so too is the point (-x,y). Since y corresponds to cos(x) then this means that cos(-x) = cos(x).
