-12y+14-9y=14
-21y=0
y=0, x=7
Answer:
x
Step-by-step explanation:
Answer:
this would be quantitative.
Step-by-step explanation:
because its an amount like dollars of sales per week so it would be quantitative or numbers
Answer:
6. <u> (2x - 1) </u>
(3x + 2)
8. <u> y - 3 </u>
y² - 3y + 9
Step-by-step explanation:
6. <u> 2x² + 9x - 5</u>
3x² + 17x + 10
= <u>(2x - 1) (x + 5)</u>
3x² + 17x + 10
= <u>(2x - 1) (x + 5)</u>
(3x + 2) (x + 5)
= <u> (2x - 1) </u>
(3x + 2)
8. <u>y² - 9 </u>
y³ + 27
= <u> (y + 3) (y - 3)</u>
y³ + 27
= <u> (y + 3) (y - 3) </u>
(y+3) (y² - 3y + 9)
= <u> y - 3 </u>
y² - 3y + 9
Answer:
<h2>m
F = 34°</h2>
Step-by-step explanation:
If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°
To find mF add mE and m F and equate it to 90 to find x then substitute it into the expression for mF
Thats
mE + mF = 90
9x - 38 + 2x + 40 = 90
11x + 2 = 90
11x = 90 - 2
11x = 88
Divide both sides by 11
x = 8
Now we have
if m F = 9x - 38
m F = 9( 8) - 38
mF = 72 - 38
We have the final answer as
<h3>m
F = 34°</h3>
Hope this helps you
