She needs to do at least 8 a day
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
First make x = 4 and y = 3 in the equation y = -1/2x + 5
it should look like 3 = -1/2(4) + 5 now we can solve
-1/2 * 4 = -2 → 3 = -2 +5
-2 + 5 = 3 → 3 = 3
Answer:
a=40. b=140. c= 40
Step-by-step explanation:
b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.
a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.
c is Congruent to a due to the vertical angles postulate
90 degrees counterclockwise and 90 degrees cancel each other out. The coordinates of the point are only reflected over the x-axis. The point becomes (1, -4).
Hope I helped :)
Answer:
The correct answer is option B). 7x² -12x√14 + 72
Step-by-step explanation:
I<u>dentity</u>
(a - b)² = a² - 2ab + b²
Find the product
It is given that ( x√7 - 3√8)(x√7 - 3√8)
(x√7 - 3√8)(x√7 - 3√8) = (x√7 - 3√8)²
(x√7 - 3√8)² = (x√7)² - 2*x√7*3√8 +(3√8)²
= 7x² - 6x√56 + 72
= 7x² - 6x*2√14 + 72
= 7x² - 12x√14 + 72
Therefore the correct answer is option B). 7x² - 12x√14 + 72
