Answer:
Step-by-step explanation:
Let the number = x
3x + 9 = 2x - 6 Looks like you are going to get something negative here.
Subtract 2x from both sides.
3x - 2x + 9 = 2x - 2x - 6
x + 9 = -6
Subtract 9 from both sides.
x + 9 - 9 = - 6 - 9
Combine
x = - 15
Answer:
A rectangle.
Step-by-step explanation:
The point are plotted on a coordinate plane, whose outcome is presented in the image enclosed below. The figure resembles a rectangle, as all internal angles are right-angled.
First you must bring all x on one side and all normal numbers on the other side:
6x+3 = 5x - 5 )-5x
1x + 3 = -5 )-3
1x = -8
At last you must divide 8 by the number, that is multiplied with x:
1x = -8 ):1
x = -8
Answer:
<h2>y - 5 = 2(x - 10)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
The formula of a slope:

We have the points (10, 5) and (4, -7). Substitute:


Answer:
k = 6
Step-by-step explanation:
Using synthetic division, we find the remainder from the division to be ...
remainder = 4k+2
Then we need to find k such that ...
4k +2 = 26
4k = 24 . . . . subtract 2
k = 6 . . . . . . divide by 4
The value of k is 6.
