I'll use substitution. I think that's the easiest.

11x + 8y = -16
x = 4y + 10

Plug in: 11(4y + 10) + 8y = -16

Simplify: 44y + 110 + 8y = -16

Simplify: 52y + 110 = -16

Subtract from both sides: 52y = -16 - 110

Simplify: 52y = -126

Divide: y = -126/52

Simplify: -2.42 or -2 and 11/26'

I could continue to solve for x, but we can see your options and D is the only one with this value for y.

How do you solve Y=x+1 x+2y=14 in substitution?
AleksAgata [21]

Answer:

(4, 5 )

Step-by-step explanation:

Given the 2 equations

y = x + 1 → (1)

x + 2y = 14 → (2)

Substitute y = x + 1 into (2)

x + 2(x + 1) = 14 ← distribute and simplify left side

x + 2x + 2 = 14

3x + 2 = 14 ( subtract 2 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Substitute x = 4 into (1) for corresponding value of y

y = 4 + 1 = 5

Solution is (4, 5 )

Which of the statements below are true? Select all that apply.
creativ13 [48]
A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive.
B is false: correlation can also be negative.
C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation.
D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation.
E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive).
F is false: it measures the strength and direction between two numerical variables!
In conclusion, A, D, and E are true.
