Solve the equation<br><br> 1 . J + -2 = -22
olganol [36]

J + -2 = -22

Adding a negative number changes the equation to subtract ruin:

J - 2 = -22

Now add 2 to both sides to get the answer:

J = -20

Please answer correctly !!!!!!!!!! Will mark brainliest !!!!!!!!!!!!

Answer:

see explanation

Step-by-step explanation:

(1)

Given

g(r) = (r + 14)² - 49

To obtain the zeros, let g(r) = 0 , that is

(r + 14)² - 49 = 0 ( add 49 to both sides )

(r + 14)² = 49 ( take the square root of both sides )

r + 14 = ± \sqrt{49} = ± 7 ( subtract 14 from both sides )

r = - 14 ± 7, then

r = - 14 - 7 = - 21 ← smaller r

r = - 14 + 7 = - 7 ← larger r

(2)

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

g(r) = (r + 14)² - 49 ← is in vertex form

with vertex = (- 14, - 49 )

Solve 10(1 + 3b) = −20, justifying each step with an algebraic property.
Delicious77 [7]
The correct answer is B = -1

10(1 + 3B) = -20

10 + 30B = -20

-20 - 10 = -30

30B = -30

B = -1


Hope this helps :)
