Answer:
The integer is 1 or 9.
Step-by-step explanation:
Let the integer be x, then:
x^2 + 7 = 10x - 2
x^2 - 10x + 9 = 0
(x - 9)(x - 1) = 0
x = 1, 9.
Verifying
9^2 + 7 = 88
10*9 - 2 = 88 So 9 is correct.
1^2 + 7 = 8
10*1 - 2 = 8 So 1 is also correct.
Answer:
a) h(x)
b) q(x)
c) w(x)
Step-by-step explanation:
Finding the answers for this is easy. Take two values for x that shows a different Y-value for each function on the graph and place them in the equations suggested to see which equation match their Y-value on the graph.
Let's take x = -1 and x = 1.
a) h(x) = | -x + 3 |
| - (-1) + 3| = | 4 | = 4
| - 1 + 3 | = | 2 | = 2
h(x) passes through (-1,4) and (1,2)
b) q(x) = | x | + 3
|-1| + 3 = 4
| 1 | + 3 = 4
q(x) passes through (-1,4) and (1,4)
c) w(x) = | x+ 3 |
| -1 + 3 | = | 2 | = 2
| 1 + 3 | = | 4 | = 4
w(x) passes through (-1,2) and (1,4)
Answer:
4+(-11)
Step-by-step explanation:
you need to put the negative 11 in ()
Answer:
-1, 3, 7
Step-by-step explanation:
y = 4(-1) + 3
y = -4 + 3
y = -1
y = 4(0) + 3
y = 0 + 3
y = 3
y = 4(1) + 3
y = 4 + 3
y = 7
1/2x + y = 3
Solve the equation to put it in slope intercept form. (y=mx+b)
1/2x + y = 3
Subtract 1/2x from both sides.
y = -1/2x + 3
The y-intercept (where the line crosses the y-axis) is three and the slope (rise over run) is -1/2.
Hope this helps!
