Answer:
1 =b
Step-by-step explanation:
8 = b - 1 + 8b
Combine like terms
8 = 9b -1
Add 1 to each side
8+1 = 9b-1+1
9 = 9b
Divide each side by 9
9/9 = 9b/9
1 =b
Answer:
1
Step-by-step explanation:
Group like terms
8b + b = 8+ 1
simplify each sides
9b = 9
divide both sides by 9
9b÷9 = 9÷9
cancel out
answer is equal to 1
b = 1

Which equation is equivalent to the given equation? x^2 - 10x = 14
Answer:
(x - 5)² = 39
Step-by-step explanation:
Given
x² - 10x = 14
To obtain an equivalent equation use the method of completing the square.
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39
I believe that the answer you are looking for is (x-5)²-39, if you use the completing the square method.
Solution:
x²-10x=14
Transferring 14 from the right side to the left side,
x²-10-14=0
Squaring the equation,
(x-5)²-39, or (x-5)²=39 (Depends on how you prefer to write it).
So, that is the final answer. I hope this helped. If you have any questions about the answer, please let me know. Enjoy your day and take care!

use the diagram on the right. How many planes contain both the line and the point
a. FG and point P
b. EP and point G
Part (a)
Answer: 0-------------------
Explanation:
Point P is part of 3 planes or faces of this triangular prism:
plane PEF (the front slanted plane)plane PEH (the left triangular face)plane PHG (the back rectangular wall)Notice how each three letter sequence involves "P", though this isn't technically always necessary. I did so to emphasize how point P is involved with these planes.
Each of the three planes mentioned do not involve line FG
Plane PEF only deals with point FPlane PEH doesn't have any of F or G involvedplane PHG only involves GSo there are no planes that contain line FG and point P.
==================================================
Part (b)
Answer: 0-------------------
Explanation:
It's the same idea as part (a) earlier. The planes involving point G are
plane GQF (triangular face on the right)plane GFE (bottom rectangular floor)plane GHP (back rectangular wall)None of these planes have line EP going through them.
As an alternative, we could reverse things and focus on all of the planes connected to line EP. Those 2 planes are
plane PEH (triangular face on the left)plane PEF (front slanted rectangular face)None of these planes have point G located in them.
Can the distributive property be used to rewrite

For 30 minutes you do a combination of walking and jogging At the end of your workout your screen displays 2.5 miles you know that you walk 0.05 miles per minute and jog 0.1 per minute how much time were you walking. Jogging.
Please write the equation and solve it. Thank you
First person to answer will get brainliest
Let the time spent in walking = x minutes
And the time spent in jogging = y minutes
If I walk with the speed = 0.05 miles per minute
Distance covered in walking = Speed × Time
= 0.05x miles
If I jog with the speed = 0.1 miles per minute
Distance covered in jogging = Speed × Time
= 0.1y miles
Since, screen displays the distance covered in walking and jogging = 2.5 miles
Equation for the situation will be,
0.05x + 0.1y = 2.5
5x + 10y = 250
x + 2y = 50 -------(1)
Total time spent in walking and jogging = 30 minutes
Therefore, equation for the situation will be,
x + y = 30 ----- (2)
By subtracting equation (2) from equation (1),
(x + 2y) - (x + y) = 50 - 30
y = 20 minutes
By substituting the value of y in equation (2),
x + 20 = 30
x = 10 minutes
Therefore, time spent in walking is 10 minutes and time spent in jogging is 20 minutes.

first 40 hours and then gets time-and-a-half for the rest of the time. How
much money did she make this week?
9514 1404 393
Answer:
$542.30
Step-by-step explanation:

(40 h)($9.35/h) = $374.00
For the next 52 -40 = 12 hours, Alice made ...
(12 h)($9.35/h × 1.5) = $168.30
Then the total Alice made for working 52 hours is ...
$374.00 +168.30 = $542.30
