Answer: (7x + 8)³ ↔ the cube of the sum of 7x and 8
7(x + 8)³ ↔ 7 times the cube of the sum of x and 8
7x³ + 8 ↔ 8 added to the product of 7 and x cubed
(7x)³ + 8 ↔ 8 added to the cube of 7x
Step-by-step explanation:
(7x + 8)³ ↔ the cube of the sum of 7x and 8: for this case you will find that the values are into the parenthesis, then for each value apply the same exponent because of that all the values into the parenthesis are elevated to the cube,
7(x + 8)³ ↔ 7 times the cube of the sum of x and 8: in this example the 7 is multiplying all the values into the parenthesis, then you can find six times the sum of x and 8 elevated to the cube, also keep in mind that exponent which is 3 only apply to the values which are into the parenthesis and this values are the x and 8
7x³ + 8 ↔ 8 added to the product of 7 and x cubed: for this equation, you will find that 7 is multiplying to the x elevated to the cube after that, the 8 is added to this product.
(7x)³ + 8 ↔ 8 added to the cube of 7x: this final we can see that the values into the parenthesis are elevated to cube, the values are 7 and x, after this equation the 8 is added to the product.
Point-slope form : y-y₁=m(x-x₁)
Perpendicular to the given line, and passes through (-4, -3)
Given line slope : -4
How we found slope : I found 2 exact points, and found the slope by doing the slope formula (y₂-y₁/x₂-x₁)
m = slope
However, when a line is perpendicular, we must find the negative reciprocal of our slope.
Slope₁ = -4
Slope ₂ = 1/4
Simply plug everything in.
y - y₁ = m(x - x₁)
y + 3 = 1/4(x +4)

Answer:
Step-by-step explanation:
After distributing:
Simplify further by combining like terms
Stock A: 400 × 3 = $1,200
Stock B: 500 ÷ 2 = $250
$1,200 - $250 = $950
I can help with CL 2-107. All you have to do is simplify the equation on both sides, and then isolate <em>w</em> to find its value.
6w - 5 + 8w - 2w - 3 = 9w - 24
(-5) + 12w - 3 = 9w - 24
-8 + 12w = 9w - 24
-8 + 3w = -24
3w = -16
w =
w = -5.33
Hope that helps! Sorry I couldn't help with the other ones!
