Answer:
1.5
Step-by-step explanation:
The rate of change is also the slope or m. This equation is in slope intercept form which is y=mx+b. m is the rate of change. m=1.5.
Answer:
B.3x2 - 4
Step-by-step explanation:
(f+g)(x) ➡ f(x) +g(x)
add up the functions
2x2 + 3 + x2 - 7 = 3x2 - 4
Answer:
Can you explain the question lol in so confused
Step-by-step explanation:
Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25
