Answer:
37, 49
Step-by-step explanation:
Divide 74 by two to get the first x. 74 / 2 = 37
Subtract 77 from 126 to get the second x. 126 - 77 = 49
Answer:
x=4 and y=2
Step-by-step explanation:
Let x be the variable.
36x^2 - 146x - 22 = 0
Let a = 36, b = -146, c = -22
The picture shows the set up. You do the math.
For number 1, the x-intercept is -1.5 and the y- intercept is 3. For number 2, the x-intercept is 8 and the y-intercept is -4. For number 3, the x-intercept is -10 and the y-intercept is 5. To get these answers, use the formula of y=mx+b. M is the slope and b is the y-intercept so, for number 3, you need to divide everything by -2 to get y alone, then add 1/2 to both sides to use inverse operations. The real equation for number 3 is y=1/2x+5.
