Answer:
10+30r
Step-by-step explanation:
-2+5(2+6r)
expand 5(2+6r)
5x2=10
(6r)x(5)=30r
so it is 10+30r
then add that to -2
8+30r
Hope that helps :)
The slope of each line segment of ΔQRS are-
- QR = 3/10
- RS = - 10/3
- QS = -7/13
<h3>What is meant by the slope of the line?</h3>
- A slope of a line is defined in mathematics as the change in y coordinate to regard to the shift in x coordinate.
- The net change in y-coordinate is denoted by Δy, whereas the net change in x-coordinate is denoted by Δx.
For the given question,
The coordinates of each vertices of the triangle are-
Q = (-7, -2)
R = (3, 1)
S = (6, -9)
The formula for the slope of the line segment.
Slope = m = (y2 - y1)/(x2 - x1)
Slope QR = (1 + 2)/(3 + 7)
Slope QR = 3/10
Slope RS = (-9 - 1)/(6 - 3)
Slope RS = - 10/3
Slope QS = (-9 + 2)/(6 + 7)
Slope QS = -7/13
Thus, the slope of the each line segment of the given triangle QRS is found.

Based on the fact that the expressions to be subtracted have the same base, the result is 8.305 x 10⁸.
<h3>What is the result of the subtraction?</h3>
The first number in standard form is:
= 8.4 x 10⁸
= 840,000,000
The second number in standard form is:
= 9.5 x 10⁶
= 9,500,000
The result is:
= 840,000,000 - 9,500,000
= 830,500,000
In scientific notation this is:
= 8.305 x 10⁸

Answer:
6(x-4y) = 6x - 24y
Step-by-step explanation:
Here, we want to expand the given expression
We can do this using the distributive approach
We have this as;
(6 * x) - (6 * 4y)
= 6x - 24y
Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.
All we have to do is multiply all these numbers by 4 to see which one is equal to 32.
6 * 4 = 28
10 * 4 = 40
8 * 4 = 32
4 * 4 = 16
c. is the correct answer
