Answer:

Step-by-step explanation:

g(x)=3x−2

g(−2)= 3(-2) - 2 (after substituting -2 for x): g(-2) = -6 - 2 = -8

g(0)= 3(0) - 2 = -2

g(5)= 3(5) - 2 = 13

G(x) = 3x-2
g(-2) = 3(-2) - 2
g(-2) = -6-2
g(-2) = -8

g(0) = 3(0)-2
g(0) = 0-2
g(0) = -2

g(5) = 3(5)-2
g(5) = 15-2
g(5) = 13

Answer: C) 4

==========================================================

Explanation:

Let's isolate t

-3 > -3t + 6

-3+3t > 6

3t > 6+3

3t > 9

t > 9/3

t > 3

This means any value can replace t such that it's larger than 3.

Something like t = 1/3 = 0.33 won't work since it's not larger than 3.

But something like t = 4 would work because it makes t > 3 true.

That's why choice C is the final answer.

Write the equation of the line that passes through the points (−4,1) and (−9,5). Put your answer in fully reduced point-slope fo

valina [46]

Step-by-step explanation:

gradient(m)=change in y/change in x

=5-1/-9-(-4)

=4/-9+4

=4/-5

equation now

y-y1=m(x-x1)

y-1=4/-5[x-(-4)]

y=4/-5(x+4)+1

y=-4/5x-16/5+1

y=-4/5x-21/5

Rochelle works part-time at the college museum, which pays her at a rate of $10 per hour. She also makes small bracelets that sh

Westkost [7]

We know for our problem that Rachel makes $10 per hour. Since $x$ represent the number of hours that she works, $10x$ will be the total amount that she will make for working $x$ hours. We also know that she sells bracelets for $5 each. Since $y$ represents the number of of bracelets that she sells, $5y$ will be her total revenue for selling $y$ bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of $10x$ and $5y$ must be equal or greater than 200:

$10x+5 \geq 200$

We can conclude that <span>the graphs that shows the inequality that represents this situation, with its solution region shaded is:</span>

1. Find the vertex of the following quadratic equations:<br> a) f(x) = (x – 4)2 + 7

RSB [31]

Answer: It is not possible to find the vertex of the stated equation as it is in the form of f(x) = mx + b, a linear equation.

Step-by-step explanation:

Being in the form f(x) = mx + b, it is not possible to find a vertex due to the fact that there is none. This is because when an equation is written in the linear form it is representing a line not a parabola.

Given a parabola it is possible to find a vertex because in that case there is one.
