Answer:
72 words per minute
Step-by-step explanation:
42 × y = 1 × 3024
42y = 3024
42y ÷ 42 = 3024 ÷ 42
y = 72
Answer:
(x + 5)(3x + 5)
Step-by-step explanation:
(x - 5)(x + 8) + (x + 5)(2x - 3) ← factor out (x + 5) from each term
= (x + 5)(x + 8 + 2x - 3)
= (x + 5)(3x + 5)
Answer:
(a) -7, (b) 2
Step-by-step explanation:
a) When x = 0,
=> x² - 8x - 7
=> (0)² - 8(0) - 7
=> 0 - 0 - 7
=> - 7
b) When x = -1,
=> x² - 8x - 7
=> (-1)² - 8(-1) - 7
=> 1 + 8 - 7
=> 9 - 7
=> 2

<h3>Slope = 10</h3><h3>y intercept at (0,750)</h3><h3>x intercept at (-75, 0)</h3>
=====================================
Explanation:
The function f(x) = 10x+750 is the same as y = 10x+750
It is in the form y = mx+b where m = 10 is the slope and b = 750 is the y intercept. So that covers the first two parts of the answer.
The x intercept is found by replacing y with 0, then solving for x like shown below
y = 10x + 750
0 = 10x + 750
10x + 750 = 0
10x = -750 ....... subtract 750 from both sides
x = -750/10 .... divide both sides by 10
x = -75
So x = -75 plugged into the function leads to y = 0
Meaning that x = -75 and y = 0 pair up together to get the point (-75,0) which is the x intercept. This is the location where the line crosses the x axis.
