Answer:
y = 4x + 1
Step-by-step explanation:
first use y-y/x-x
(-2, -7), (3, 13)
-7-13 / -2-3
-20 / -5
4x is the slope
i'm going to do another way of finding the y-intercept, but you should learn how to do the way you're being asked here
y = mx + b
-7 = 4(-2) + b
-7 = -8 + b
1 = b
y = 4x + 1 is your answer
A prism always has two congruent, parallel basses.
Answer:
Well to figure this out you must first multiply 9x2 which equals 18. Now you subtract 18-6 which equals 12. Rachael scored 12 points
Answer in interval notation is (-3, 1)
This is the same as saying -3 < x < 1
=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.
Answer:
option a
step-by-step explanation:
To rationalize the expresion we need to multiply and divide the expression by the conjugate of the denominator as follows
sqrt(9) / (sqrt(3) + sqrt(x)) = sqrt(9) ((sqrt(3) - sqrt(x)) / ((sqrt(3) + sqrt(x))(sqrt(3) - sqrt(x)))
3((sqrt(3) - sqrt(x)) / (3 - x)
So the result es option a:
(3sqrt(3) - 3sqrt(x)) / (3 - x)
