Answer:
What are the numbers in the parentheses?
12a+7c=315
how to solve for/what is a?
Answer:
Well I mean There are multiple solutions I think, a = 26.25
Step-by-step explanation:
Simplifying
12a + 7c = 315
Solving
12a + 7c = 315
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-7c' to each side of the equation.
12a + 7c + -7c = 315 + -7c
Combine like terms: 7c + -7c = 0
12a + 0 = 315 + -7c
12a = 315 + -7c
Divide each side by '12'.
a = 26.25 + -0.5833333333c
Simplifying
a = 26.25 + -0.5833333333c
[tex]12a+7c=315\\\\\implies 12a = 315-7c\\\\\implies a = \dfrac{315-7c}{12}\\\\\implies a = \dfrac{7}{12}(45-c)[/tex]

Answer:
48 square units
Step-by-step explanation:
area of triangle = base * height / 2
base = x+1
height = 8x
area = (x+1)(8x)/2 = (8x²+8x)/2 = 4x²+4x
area of rectangle = length * width = (5x+1)(x) = 5x²+x
set the two areas to be equal to each other
5x²+x = 4x²+4x
divide both sides by x as that is a multiple of each value on each side
5x + 1 = 4x + 4
subtract 4x from both sides to limit the variable to one side
x + 1 = 4
subtract both sides by 1 to isolate the variable
x = 3
area = (5x+1)(x) = (5*3+1)(3) = 16 * 3 = 48 square units

Compute the NPV for Project M if the appropriate cost of capital is 7 percent
Based on the cashflow of Project M and its appropriate cost of capital, the NPV can be calculated to be $465.92.
What is the NPV of Project M?The NPV is the present value of the cash inflows less the present value of the cash outflows.
= ∑ (Cash inflow / (1 + cost of capital) ^ year of inflow) - Cost outflow

Answer:
x = 5
Step-by-step explanation:
70 - 4x = 30 + 4x
Add 4x on both sides of the equation,
70 - 4x + 4x = 30 + 4x + 4x
70 = 30 + 8x
Subtract 30 from both sides of the equation to isolate 8x,
70 - 30 = 30 + 8x - 30
40 = 8x
Divide both sides of the equation by 8 to solve for x,
40 ÷ 8 = 8x ÷ 8
5 = x
Answer:
= 5 groups.
Step-by-step explanation:
Solve the equation 70 - 4x = 30 +4x 70 - 30 = 4x + 4x 40 = 8x x = 52. Substitute the equation

Answer:

a notebook costs $2.50
a poem costs $1.50
B
he can buy 3 pens (and correspondingly 9 notebooks)
Step-by-step explanation:
x = price of 1 notebook
y = price of 1 pen
4x + 3y = 14.5
5x + 6y = 21.5
let's multiply the first equating by -2 and then add both equations
-8x - 6y = -29
5x + 6y = 21.5
----------------------
-3x 0 = -7.5
x = 2.5 = $2.50
4×2.5 + 3y = 14.5
10 + 3y = 14.5
3y = 4.5
y = 1.5 = $1.50
p = number of pens
n = number of notebooks
n = 3p
p×1.5 + n×2.5 = 27
p×1.5 + 3p×2.5 = 27
(1.5 + 7.5)p = 27
9p = 27
p = 3

he table below represents an exponential function, g, that has been vertically shifted from the parent function, f(x) = 2x. x 0 1 2 3 4 g(x) -11 -10 -8 -4 4 Determine the size of the shift from function f to function g. Then, plot the points of a function that is shifted only half as much as g from the parent function, f. Use the same x-values as used in the table for function g.
Answer:
1. The size of shift from function f to function g is -12
2. The plot of the points of a function that is shifted only half as much as g from the parent function f is in the attached file in blue color.
Step-by-step explanation:
Parent function: f(x)=2^x
x=0→f(0)=2^0→f(0)=1
x=1→f(1)=2^1→f(1)=2
x=2→f(2)=2^2→f(2)=4
x=3→f(3)=2^3→f(3)=8
x=4→f(4)=2^4→f(4)=16
Size of the shift from function f to function g: s
s=g(0)-f(0)=-11-1→s=-12
s=g(1)-f(1)=-10-2→s=-12
s=g(2)-f(2)=-8-4→s=-12
s=g(3)-f(3)=-4-8→s=-12
s=g(4)-f(4)=4-16→s=-12
Points of a function h that is shifted only half as much as g from the parent function, f. Use the same x- values as used in the table for function:
s2=s/2→s2=(-12)/2→s2=-6
x h(x)
0 1+(-6)=1-6=-5
1 2+(-6)=2-6=-4
2 4+(-6)=4-6=-2
3 8+(-6)=8-6=2
4 16+(-6)=16-6=10
