Answer:
the slope in the equation is 5, while the slope on the graph is 2
Answer:
Divide 9 from both sides.
Step-by-step explanation:
The first step to solving this equation is to add 23 to both sides.
9x - 23 (+23) = 49 (+23)
9x = 49 + 23
9x = 72
The second step is to isolate the x and divide 9 from both sides:
(9x)/9 = (72)/9
x = 72/9
x = 8

Answer:
<h3>k = 10</h3>
Step-by-step explanation:
Given the equation;

We are to find the value of k.
Cross multiply;

Divide both sides by 10

Hence the value of k is 10
Answer:
x = 3
Step-by-step explanation:
Given
f(x) = - 10x + 45 and f(x) = 15, then equating gives
- 10x + 45 = 15 ( subtract 45 from both sides )
- 10x = - 30 ( divide both sides by - 10 )
x = 3
