Answer:
2
Step-by-step explanation:
f(x) = 2x - 3 is a linear function
The rate of change of a linear function is the measure of the slope.
The equation is in slope- intercept form, that is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 has slope m = 2
Thus rate of change = 2
Answer: 54
<u>Step-by-step explanation:</u>
replace "a" with "-2" in the g-equation
g(a) = a² - 4a + 42
g(-2) = (-2)² - 4(-2) + 42
= 4 + 8 + 42
= 54
Answer:3
Step-by-step explanation:
Round 3.38 to the nearest ten
Rounding up to the nearest 10, we look at the digits on the left hand side of the decimal point. If the number on the right of the decimal point is less than 5, we ignore it.if it is greater than 5, we add one to the last digit on the right hand side.
In this case, the first digit on the left hand side is less than 5, so we ignore it. Rounding up to the nearest ten,the 0.38 is ignored.
Therefore, it becomes 3.0 = 3
To the nearest ten

When Andy walks in you fall
Answer:
1 and 2
Step-by-step explanation:
If y was 1: -2 x 1 + 18 = -2 + 18
= 16 This works
If y was 2: -2 x 2 + 18 = -4 + 18
= 14 This works
If y was 3: -2 x 3 + 18 = -6 + 18
= 12 This does not work since -2y + 18 has to be <u>greater</u> than 12.
