10x2 +7x -12=15
-7x. -7
x=8
Answer:
y = 2x + 1
Step-by-step explanation:
Given a point and the slope, we can plug in these values into the equation to find the value of b:
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
Plug b into the equation:
y = 2x + 1
Answer:
a=1
Step-by-step explanation:
7(5a-4)-1=14-8a
Distribute
35a - 28 -1 = 14 -8a
Combine like terms
35a -29 = 14 -8a
Add 8a to each side
35a+8a -29 = 14 -8a+8a
43a -29 = 14
Add 29 to each side
43a -29+29 = 14+29
43a = 43
Divide each side by 43
43a/43 = 43/43
a =1
Area of the rectangle = (18 m) (12 m) = 216 m²
Area of the triangle cutout = 1/2 (7 m) (9 m) = 63/2 m²
Area of the shaded region = 216 m² - 63/2 m² = 369/2 m² = 184.5 m²
Answer:
No
Step-by-step explanation:
Because intergerss are there positive opposite and its negative
