Answer:
b ≤ -4
Step-by-step explanation:
4b−4≤−20
4b - 4 + 4 ≤ - 20 + 4
4b ≤ -16
Divide both sides by 4
b ≤ -4
Answer:
x = -2.5
Step-by-step explanation:
Step 1: Write equation
-6.2 - 12.6x = 5.8 - 7.8x
Step 2: Solve for <em>x</em>
<u>Add 12.6x on both sides:</u> -6.2 = 5.8 + 4.8x
<u>Subtract 5.8 on both sides:</u> -12 = 4.8x
<u>Divide both sides by 4.8:</u> x = -2.5
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-6.2 - 12.6(-2.5) = 5.8 - 7.8(-2.5)
-6.2 + 31.5 = 5.8 + 19.5
25.3 = 25.3
Answer:
The point slope form of the line would be y + 4 = 2/3(x - 8) and the equation of the line would be y = 2/3x - 28/3
Step-by-step explanation:
To find the point-slope form of the line, start with the base form of point-slope form. Then input the point we have and the slope in the appropriate places.
y - y1 = m(x - x1)
y - -4 = 2/3(x - 8)
y + 4 = 2/3(x - 8)
Now to find the slope intercept form, you simply need to solve for y.
y + 4 = 2/3(x - 8)
y + 4 = 2/3x - 16/3
y = 2/3x - 28/3
Answer: The sum =14
Step-by-step explanation:
Given that n=2
And
sum = cube of a number, n, and 16 which can be expressed mathematically as
n^3 + 6
2^3 + 6
8 + 6= 14
