y= 6[tex]x^{2}[/tex] - 36x + 58

Step-by-step explanation:

6 ( [tex]x^{2}[/tex] - 6x +9) + 4

6[tex]x^{2}[/tex] - 36x + 54 + 4

6[tex]x^{2}[/tex] - 36x + 58

Step-by-step explanation:

let amt of money Raju has be r and Ann be a.

a + r = 1560

a = 1560 - r --(1)

r - 50 = 5(a + 50)

r = 5a + 300 --(2)

sub (1) into (2):

r = 5(1560 - r) + 300

r = 8100 - 5r

6r = 8100

r = 1350

therefore he has $1350 at first.

The amount of money Ann has at first is $1350.

An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.

We have,

Let the amount of money Raju = R

Let the amount of money Ann = A

Now,

Raju and Ann saved a total of $1560.

This statement can be written as:

R + A = 1560 ____(1)

After Raju gave Ann $50, Raju had 5 times as much money as Ann.

This statement can be written as:

R - 50 = 5 ( A + 50 )

R - 50 = 5A + 250

R - 5A = 250 + 50

R - 5A = 300 _____(2)

From (1)

R = 1560 - A _____(3)

Putting (3) in (2),

1560 - A - 5A = 300

1560 - 6A = 300

1560 - 300 = 6A

1360 = 6A

A = 1260 / 6
A = 210

Putting A = 210 in (3) we get,

R = 1560 - A

R = 1560 - 210

R = 1350

Thus the amount of money Ann has at first is $1350.

Can be the answer probably

Step-by-step explanation:

Answer: C

Step-by-step explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Hope this helps! :)

Answer:

2/3

Step-by-step explanation:

A = rolling a six

B = rolling a number less than 4

Probability of A or B

P(A) or P(B) = P(A) + P(B) - P(AnB)

Probability = (number of required outcome / Total possible outcomes)

P(A) = 1 / 6

P(B) :

Required outcomes = (3, 2, 1) = 3

P(B) = 3/6 = 1/2

P(AnB) = A={6} ; B = {1,2,3} ; AnB = {}

P(AnB) = 0

Hence,

P(A) or P(B) = 1/6 + 1/2 - 0

= (1 + 3) / 6

= 4/ 6

= 2/3

Step-by-step explanation:

Angle Measurement Units

To convert from different units for angle measurements, we have to recall that:

180 degrees = π radians

If we are given the angle in degrees, multiply by π/180 to convert it to radians.

If the angle is given in radians, multiply by 180/π to convert to degrees.

We are given the angle:

[tex]\displaystyle x=\frac{15}{16}\pi[/tex]

Multiplying by 180/π:

[tex]\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}[/tex]

[tex]\displaystyle x=\frac{15*180}{16}[/tex]

Step-by-step explanation:

Your statement is a little ambiguous due to type mistake, so I am assuming you meant to say:

'if 12 fl. oz. bottles cost $84 how much does one bottle cost? Find the Unit Rate.

so I am solving based on '12 fl. oz.' bottles costing $84.

Answer:

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

Step-by-step explanation:

We know that a unit rate is basically a fraction (also called ratio) between two different units with a denominator of 1.

For example, kilometers per hour, and heartbeats per minute, etc.

Here, I assume, by 'unit rate' means you mean to say 'cost per fl. oz.'

Given

The cost of 12 fl. oz. bottlers = cost $84

The cost of 1 bottle cost = $84 ÷ 12 oz = 7 $ per fl. oz.

Hence,

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

Answer:

The hotel manager under-estimated. Without estimation, the exact price would be $17,556.

Step-by-step explanation:

He should've over-estimated the money to $210, and the mattresses to 90.  So 210 × 90 is $18,900. So even if he did underestimate or overestimate, he still would not have been able to afford the mattresses.

Answer:

hotel has a budget of $16,000 to buy 84 new mattresses. Each mattress costs $209. The hotel manager says, “Since 80 × $200 = $16,000, I can stay within the budget.”

Answer:

3 points = 2

2 points = 6

1 point = 8

Step-by-step explanation:

Given that:

Total point scored = 26

Let number of 3 point basket = x

Number of 2 point basket = x + 4

Number of free throws = x + x + 4 = 2x + 4

Hence,

Total 3 points = 3x

Total 2 points 2(x + 4)

Total free throw points = 2x + 4

3x + 2(x + 4) + 2x + 4 = 26

3x + 2x + 8 + 2x + 4 = 26

7x + 12 = 26

7x = 26 - 12

7x = 14

x = 2

Number of 3 points = x = 2

2 points = (x+4) = 2+4 = 6

1 point = (2x+ 4) = 2(2) + 4 = 8

The number of free-throws, 2-point shots, and 3-point sho ts he made are;

free-throws = 8

2 points = 6

3 points = 2

Let the number of 3 points basket be x

He scored four more 2-point baskets than he did 3-point baskets. Thus;

y = x + 4

number of free-throws equaled the sum of the number of 2-point and 3-point sho ts made. Thus;

z = x + x + 4

z = 2x + 4

Thus;

Total 3 points = 3x

Total 2 points = 2(x + 4)

Total fr ee points = 2x + 4

Since he scored a total of 26 points, then;

Step-by-step explanation:

The length of the longest piece will be 15 ft.

We have a 48 ft rope is cut into 5 pieces according to the ratio →

2 : 2 : 3 : 4 : 5.

We have to determine the length in feet of the longest piece.

Now -

2x + 5x = y

x = [tex]$\frac{y}{7}[/tex]

Smallest piece is of length → 2x → [tex]$\frac{2y}{7}[/tex]

According to the question, we have -

Length of rope = 48 ft

Ratio in which they are cut = 2 : 2 : 3 : 4 : 5.

Therefore -

2x + 2x + 3x + 4x + 5x = 48

16x = 48

x = 3

Length of the longest piece = 5x =  5 x 3 = 15ft

Hence, the length of the longest piece will be 15 ft.

Answer:

y = x + 4

y = -2x - 4

Step-by-step explanation:

Since equation of the line having slope 'm' and y-intercept 'b' is given by,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of line passing through (1, 5) and (-1, 3),

m = [tex]\frac{5-3}{1+1}[/tex] = 1

y-intercept 'b' = 4

Therefore, equation of the line is,

y = 1.x + 4

y = x + 4

Now slope of another line passing through (-4, 4) and (-1, -2) will be,

m = [tex]\frac{4+2}{-4+1}[/tex]

m = -2

y-intercept 'b' of this line = -4

Equation of the other line,

y = (-2)x - 4

y = -2x - 4

Therefore, system of equations is,

y = x + 4

y = -2x - 4

The system of equations is given by: y = x + 4 and y = -2x - 4

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

The first line passes through point (-1, 3) and (1, 5) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{5-3}{1-(-1)} (x-(-1))\\\\y=x+4[/tex]

The second line passes through point (-4, 4) and (-1, -2) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4=\frac{-2-4}{-1-(-4)} (x-(-4))\\\\y=-2x-4[/tex]

The system of equations is given by: y = x + 4 and y = -2x - 4
