X = -2
y = 2
You can get this by setting the two different y's equal to each other and solving for the x value.
Answer:
y = ½x - 1.5
Step-by-step explanation:
(x,y) = (5,1)
m = ½
y = mx + c
1 = ½(5) + c
1 = 2.5 + c
1 -2.5 = c
-1.5 = c
impute m and c only into the equ.
y = ½x - 1.5
Answer:
80
Step-by-step explanation:
1/10 = 10% = 0.1
0.1 x 8 = 0.8 = 80%
Answer:
-3 < x ≤ 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.
∴ -3 < x ≤ 7
Not exactly correct.
y=mx+b Slope is m and y intercept is b.
So, here count the units for the slope. it goes barley to the 7th box. Now, count the units for the y intercept. It goes to the fourth box.
Thus, your equation is y=7x+4
