Answer:
<QPR = 98.5 degrees
Step-by-step explanation:
a line = 180 degrees
7x + 4 + 9x - 40 = 180
16x - 36 = 180
16x = 216
x = 13.5
<QPR = 7x + 4 = 7(13.5) + 4 = 98.5
Answer: the coordinates For the purple triangle A= -4,5 B= -2,1 C=-5,2
Step-by-step explanation: To the purple triangle are A( X= -4 and Y= 5 so -4,5 for a). B(X= -2.5 and Y=1 so -2.5,1 for b ). C(X=-5 and Y= 2 so -5,2 for c).
Hope this helps
Answer:
b. All real numbers
Step-by-step explanation:
Simplify:
- 5(x-2) = (15x+6)/(3) - 12
- 5x - 10 = 5x + 2 - 12
- 5x - 10 = 5x - 10
- -10 = -10
- 0 = 0
Since both sides are equal to each other, any value of x makes this equation true.
10. slope intercept form : y = mx+b
we can see that the line hits the y-axis at +1
and that the line inclines one up one
so it would be y = x + 1
