Substitute y for -2 so <u>4x-3(-2)= 18</u>, which -3 * -2 is +6 so then it'd be <u>4x + 6 = 18</u>, then subtract 6 so <u>4x = 12</u>, then divide by 4 so <u>x = 3</u>. dont forget that in match the positive&negative signs count.
Answer:
let F=fee; R=hourly rate=1.2F ; N=number of hours
Total charge=F+NR
Total charge=F+N(1.2F)
$470=F+7(1.2F)
$470=F+8.4F
$470=9.4F
$50=F ANSWER 1: Her fee is $50

Step-by-step explanation:
To check if a solution is extraneous, simply plug it back into the original equation. If it works, then solution isn't extraneous.
√(2x−1) = 7
√(2(25)−1) = 7
√(50−1) = 7
√(49) = 7
7 = 7
So the solution isn't extraneous.
Answer:
<h2><u>
x = 8.2</u></h2>
Step-by-step explanation:
A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.
First triangle on the right:
5^2+B^2=10^2
25+B^2=100
B^2=75
B=8.66025404
B=8.7
Second triangle of left:
3^2+B^2=8.7^2
9+B^2=75.69
B^2=66.69
B= 8.16639455
B=8.2
x=8.2
