<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
Step-by-step explanation:
According to the graph, the line's x-value span from -3 to 7. Since both are open dot, they are excluded from the domain:
(-3, 7) or -3 < x < 7
Answer:
He will run 60 kilometers.
Step-by-step explanation:
285 / 95 = 3
20 x 3 = 60
Answer:
Step-by-step explanation:
a. The diameter of the circle will be 30 cm
So circumference is 3.14 * 30 = 94.2 cm.
b. Required percentage = (94.2) * 100 / (4*30)
= 78.5%.
Answer:
A; y- 4 = -2(x + 1)
Step-by-step explanation:
Here, we want to find the equation of the given line
The general form
is ;
y = mx + c
c is the y-intercept which is 2
So we have
y = mx + 2
The x-intercept where y = 0 is 1
Thus;
0 = m(1) + 2
0 = m + 2
m = -2
So the equation of the line is
y = -2x + 2
We can rewrite this in the point-slope form as:
y - 4 = -2(x + 1)
