Answer:
Step-by-step explanation:
The x-intercept exists when y = 0; the coordinate takes on the form ( , 0)
The y-intercept exists when x = 0; the coordinate takes on the form (0, ).
We will fill in the blanks in a sec.
If the x-intercept exists when y = 0, then we fill in 0 for y and solve for x:
-3(0) - x = -9 so
-x = -9 and
x = 9
The coordinate is (9, 0) for the x-intercept.
If the y-intercept exists when x = 0, then we fill in 0 for x and solve for y:
-3y - 0 = -9 so
-3y = -9 and
y = 3
The coordinate is (0, 3) for the y-intercept.
1) Distribute
Y=x^2-1x+2x-2
2) Combine like terms
Y=x^2(-1x+2x)-2
3) Slove
Y=x^2+1x-2
Answer
Y=x^2 + 1x -2
Answer:
Inital height is 20
Step-by-step explanation:
h= (-5x-5)(x-4)
h= -5x^2+15x+20
Answer:
10 and 200
Step-by-step explanation:
the two numbers are x and 18x + 20
x + (18x + 20) = 210
19x + 20 = 210
19x = 190
x = 10
Now substitute x = 10 into 18x + 20 to get the second number.
18(10) + 20
180 + 20 = 200
Answer:
Step-by-step explanation:
See attachment.
The change from x to (x-4) moved the function to the right by 4. The - 5 moved it down by 5 (as measured from the crossover/inflection point.
