Answer:
Slope is -2
y intercept is -3
Equation :y=-2x-3
Step-by-step explanation:
First you have to find the slope, the slope formula is m = y2 - y1/ x2 - x1
m = y2 - y1/ x2 - x1 (-3, 8) (7, 6)
m = 6 - 8/ 7 - (-3)
m = -2/10
m = -1/5
point-slope formula;
y - y1 = m(x - x1) m = -1/5 (-3, 8)
y - 8 = -1/5(x - (-3)
y - 8 = -1/5(x + 3)
so the answer is, B.

Answer:
last option
Step-by-step explanation:
We know that a₁ (or the first term) = 4 so we can rule out the second and third options. d (or the common difference) = 8 (because 4 + 8 = 12, 12 + 8 = 20 and so on) so our answer is the last option.
Answer:
<h2>181 440</h2>
Step-by-step explanation:
We have 9 choices for Choosing the first object
8 choices for Choosing the 2nd object
.
.
.
3 choices for Choosing the seventh object
Therefore if we want to choose7 objects without replacement from 9 objects we have : 9×8×7×6×5×4×3 = 181 440
Also ,we can calculate it this way :
9P7 = 181 440
Step-by-step explanation:
As we can see the question given
f(x) is varying accordingly to the interval
<em> f(x) = 2 if 2<x≤4</em>
The value of function is 2 for the interval 2 to 4
and interval is open at x=2 and closed at x = 4
<em> f(x) = x + 3 if 4<x<8</em>
The value of function is x + 3 and it is open at x = 4 and x = 8
<em>f(x) = 2x if x
8</em>
The value of function is 2x for x greater than or equal to 8
