Answer:
Ans wer is 2nd quadrant
( - x line and + y line )
Add them all up and divide by 6
160/6 = 26.7
Answer:
The answer is 5
Step-by-step explanation:
I had the test, and what you meant was probably: 1/2(4x-5)+5/2=10
but yes, the answer is 5
x^2 - 75 = -10x
<em><u>Add 10x to both sides.</u></em>
x^2 + 10x - 75
<em><u>Check if splitting the middle term is possible.</u></em>
<em><u>Display factors of -75.</u></em>
1 * -75
-1 * 75
-5 * 15 < (this meets the criteria)
<em><u>Split the middle term.</u></em>
x^2 - 5x + 15x - 75
<em><u>Factor each binomial.</u></em>
x(x - 5) + 15(x - 5)
<em><u>Combine factors.</u></em>
(x + 15)(x - 5) is the completely factored form of the provided quadratic.
Answer:
d = 69° , e = 32° , f = 79°
Step-by-step explanation:
d and 69° are vertically opposite angles and are congruent , so
d = 69°
e and 32° are vertically opposite angles and are congruent , so
e = 32°
69° , e , f lie on a straight line and sum to 180° , that is
69° + 32° + f = 180°
101° + f = 180° ( subtract 101° from both sides )
f = 79°
