Answer:
x = 17
Step-by-step explanation:
Direct variation is given by
y = kx where k is the constant of variation
-35 = k*7
-35/7 = k
-5 = k
y = -5x
We know y = -85
-85 = -5x
Divide each side by -5
-85/-5 = x
17 =x
Answer:
First Graph is Correct
Step-by-step explanation:
We are given the inequality:

This means any number EQUAL TO or LESS than 46
Since, we have "equal to", there should be a "closed" circle on 46 (it means 46 is included).
LESS THAN means all numbers to the "LEFT".
Looking at the 4 number lines, we can eliminate last 2 choices since they don't have closed circles.
As for the first two choices, the first choice is correct because it shows us all the numbers left of 46 and 46 included (signified by the closed circle).
So, the first number line is the solution
The car is driving at 70 miles per hour which is above the speed limit on the highway
<h3 /><h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the distance in miles and x represent the time in hours. Hence:
- Using the points (0, 0) and (3, 200)

Bob speed limit is 66.7 miles per hour
Given a car by y = 70x. The car is driving at 70 miles per hour which is above the speed limit on the highway
