Answer:
- D. Neither
- x- intercept: (-13/6, 0), y- intercept: (0, 13)
- (-1, 3)
Step-by-step explanation:
#1
<u>Substitute pairs of solutions and verify</u>
(1, 7)
(2, -7)
- -7 = -2*2 - 5
- -7 = -11
- Wrong
Correct choice is <u>D. Neither</u>
#2
<u>x- intercept: y = 0</u>
- 6x + 13 = 0
- 6x = -13
- x = -13/6
- (-13/6, 0)
<u>y- intercept: x = 0</u>
- y = 6*0 + 13
- y = 13
- (0, 13)
#3
<u>x = -1 ⇒ find y:</u>
- y - 3 = 2(-1 + 1)
- y = 3
- (-1, 3)
Step-by-step explanation:
5 (-3 x -2) - (x-3) = -4 ( 4x + 5) +13
-15x-10-x+3=-16x-20+13
-15x+16x-x=-20+13+10-3
0=0
no solution
Answer:
I got (y-7)=1/13(x+6) for point slope
and y=1/3x+13 for slope intercept form
double check me though I'm new at this
Answer:
2. C. { 0, 1, 2}
3. B. 53
6. P = 14n + 10
Step-by-step explanation:
2. The domain is the input values (or the x values)
The domain is { 0,1,2}
3. f(x) = 5x+3
where x is the number of minutes. We will let x = 10
f(10 ) = 5*10 +3
= 50+3
= 53
53 cars will pass
6. When we have 1 trapezoid, the perimeter is 5+5+8+6 = 24
When we have 2 trapezoids, the perimeter is 5+8+6+5+8+6 = 38
We add 14, when we add a second trapezoid
P = 14n + 10
p(1) = 14+10 Check for 1 trapezoid
p(2) = 14*2 +10 = 28+10 = 38 check for 2 trapezoids
<span>g(x) = 6(4)x, Section A is from x = 0 to x = 1. Your "6(4)x" needs to be written as
</span><span>g(x) = 6(4)^x, where the " ^ " indicates exponentiation.
The average rate of change of g(x) from x= 0 to x=1 is:
6(4)^1 - 6(4)^0 24 - 6
a.r.c. = ----------------------- = ----------- = 18 (answer)
1-0 1
Now do the same thing for x = 1 to x = 2.</span>
