3a+30=3a+10
30-10=3a-3a
20≠0
hope this help
∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°
Question a:
∠1 = 23°
∠2 = 90 - 23 = 67°
Ans: 67°
Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29
∠1 = 29°
∠2 = 2(29) + 3 = 61°
Ans: ∠1 = 29°, ∠2 = 61°
Answer:
x = -0.907, 2.57
Step-by-step explanation:
Quadratic Formula: 
Since we are given <em>a</em> = 3, <em>b</em> = -5, and <em>c</em> = -7 from our quadratic, we simply use the Quadratic Formula:
Step 1: Plug in variables

Step 2: Solve


Step 3: Evaluate for decimals
You should get x = -0.906718 and 2.57338 as your answers.
Answer:
its -3
all you gotta do is substitue the point in for x and y
x = -4
y = 7
