Answer:
a. gradient 4
b. gradient 3
c. gradient 1
d. gradient 1
e. gradient -2
f. gradient 3
Step-by-step explanation:
to find y intercept substitute x to be 0
i.e y=3x
y=0
(3t² +t -12t - 4)(t+2)=0
(3t³ - 5t² -26t -8) =0
t = -2
I’d make the spinner slices into thirds that are even because there would be an equal chance for each slice to be chosen. If I were to spin the spinner, I would have an equal 33.33% chance that it would land on $3, $5, or -$6. This makes it fair because they would all have an equal chance to be chosen!
The first sentence → x - 2y = -1
the second one → 3x - 2y = -3
multiply the first one by -1
you can get → -x + 2y = 1
plus two sentences together
you can get → 2x = -2
so you are able to know that x = -1
and y = 0
The equation of a circumference is 2
r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34
