Answer:
<u>Sum</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u>,</u><u>9</u><u>3</u><u>5</u><u>.</u>
Step-by-step explanation:
This is an arithmetic progression.
Sum:
n is the number of terms, n = 79
S is the sum
a is the first term, a = -8
d is common difference, d = -1-(-8) = 7
substitute:
Answer:
6x-3=3x+12
+3 . +3
6x=3x+15
-3x=-3x
3x=15
X=5
Step-by-step explanation:
Answer:
-39/8y
Step-by-step explanation:
-4/y(2)+(-7/8y)
a) For there to be a y-intercept of 3, when x=0, y=3.
- A. y=(0+1)(0-3)=-3
- B. y=0²-9=-9
- C. y=3(0)(0-3)=0
- D. y=(0+1)(0+3)=3.
So, the answer is D
b) For there to be roots of 0 and 3, there has to be factors of x and (x-3).
- The only choice that satisfies this is C
