What are the solutions to the system of equations? {y=2x2+6x−10 y=−x+5
inessss [21]
Answer: x = -5, 3/2 y = 10, 7/2

Explanation:

y = 2x^2 + 6x - 10 (1)
y = - x + 5 (2)

=> 2x^2 + 6x - 10 = - x + 5
2x^2 - 7x - 15 = 0
(2x - 3)(x + 5) = 0
=> 2x - 3 = 0
2x = 3
x = 3/2
=> x + 5 = 0
x = -5

According to (2):

y = -x + 5
y = -(-5) + 5
y = 5 + 5 = 10

y = -x + 5
y = -(3/2) + 5
y = -(3/2) + 10/2
y = 7/2

Given the domain (-4, 0,5), what is the range for the relation y = -2x +
mote1985 [20]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y =f(x) =   - 2x + 4

_________________________________

f( - 4) =  - 2( - 4) + 4

f( - 4) = 8 + 4

f( - 4) = 12

_________________________________

f(0) =  - 2(0) + 4

f(0) = 0 + 4

f(0) = 4

_________________________________

f(5) =  - 2(5) + 4

f(5) =  - 10 + 4

f(5) =  - 6

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .
