Answer:
Area of pool = 24x²-43x-56 square feet
Step-by-step explanation:
Given that:
Dimensions of rectangular swimming pool = 3x - 8 and 8x + 7
Area of the swimming pool can be calculated by multiplying the dimensions.
Area of pool = (3x-8)(8x+7)
Area of pool = 3x(8x+7)-8(8x+7)
Area of pool = 24x²+21x-64x-56
Area of pool = 24x²-43x-56
Hence,
Area of pool = 24x²-43x-56 square feet
If you have a line that goes through (-1, 7) and (8, -2), what would the equation of the line be in point-slope form?
Please use (8, -2) for x1 and y1.
Answer:
y-9 = -1/12(x-8)
Step-by-step explanation:
To write an equation of a line perpendicular to the graph of y = 12x-3 and passing through the point, we will follow the following steps.
The standard form of point-slope form of the equation of a line is given as
y − y1 = m(x − x1),
m is the slope of the unknown line
(x1, y1) is a point on the line.
Step 1: We need to calculate the slope of the known line first,
Given y = 12x-3
from the equation, m = 12 on comparison.
Step 2: get the slope of the unknown line. since the line given is perpendicular to the line y = 12x - 3, the product of their slope will be -1 i.e Mm = -1
M = -1/m
M is the slope of the unknown line
M = -1/12
Step 3: We will substitute M = -1/12 and the point (8, 9) into the point-slope form of the equation of a line i.e y − y1 = M(x − x1),
M = -1/12, x1 = 8 and y1 = 9
y-9 = -1/12(x-8)

Solve for x:
3(x - 2) = 4x + 8
Answer:
Step-by-step explanation:
3x-6=4x+8
-8-6=4x-3x
-14=x
Answer:
x = -14
Step-by-step explanation:
3(x - 2) = 4x + 8
~Distribute left side
3x - 6 = 4x + 8
~Add 6 to both sides
3x = 4x + 14
~Subtract 4x to both sides
-x = 14
~Divide -1 to both sides
x = -14

The equation that represents the canned goods order is 24x + 64y = 384.
x = number of minutes for fruit cans
y = number of minutes for vegetable cans
Explain how to calculate the x- and y-intercepts.
Step-by-step explanation:
let me explain in easy way
24x+64y=384 take x=0
24×0+64y=384
0+64y=384
64y=384
y=384 divided by 64
y=6
we got the y intercept
now lets do for x
24x+64y=384 take y=0
24x+64×0=384
24x+0=384
24x+0=384
24x=384
x=384 divided by 24
x=16 we got x intercept also
hope this helps
Answer:
Sample Answer: Substitute 0 for the x-value in the equation and solve for y. The result is y = 6, so the y-intercept is at (0, 6). Next, substitute 0 for the y-value in the equation and solve for x. The result is x = 16, so the x-intercept is at (16, 0).

PLS HELP
Answer:
2z^3 - 5z^2 + 4z - 1
Step-by-step explanation:
(2z - 1)(z^2 – 2z+ 1) =
= 2z^3 - 4z^2 + 2z - z^2 + 2z - 1
= 2z^3 - 5z^2 + 4z - 1
The polynomial in standard form will be 2z³ – 5z² + 4z – 1.
What is polynomial?A polynomial expression is an algebraic expression with variables and coefficients.
The polynomial is given below.

What is an equivalent expression for 5x + 15
We can write an equivalent expression by factoring this polynomial.
Since the GCF for these terms is 5, we can factor out a 5.
That leaves us with each term divided by 5 inside the parenthses.
So we have 5(x + 3).

You break you break your piggy bank which is filled with nickels and quarters. You have 32 coins and a total of 5.20. How many quarters and nickels do you have ?
Answer: 14 nickels and 18 quarters.
Step-by-step explanation:
Let x = Number of nickels , y = Number of quarters
As per given , we have
x+ y= 32 (i)
0.05x+0.25y= 5.20 (ii)
Multiply (ii) by 4 , we get
0.2x+y = 20.8 (iii)
Subtract (iii) from (i) , we get
0.8x = 11.2
[tex]\Rightarrow\ x=\dfrac{11.2}{0.8}\\\\\Rightarrow\ x = 14[/tex]
Put value of x in (i) , we get
y =32-14 = 18
Hence, we have 14 nickels and 18 quarters.
