Answer:

y = 2x² + 8x + 8

Step-by-step explanation:

x = t - 2 → t = x + 2

y = 2t²

Substitution:

y = 2(x + 2)²

y = 2(x² + 4x + 4)

y = 2x² + 8x + 8

Answer:

  (x, y) = (1, -6)

Step-by-step explanation:

The expression for y given by the first equation can be substituted into the second equation.

  11x +(-8x +2) = 5 . . . substitute for y

  3x +2 = 5 . . . . . . . simplify

  3x = 3 . . . . . . . . . subtract 2

  x = 1 . . . . . . . . . divide by 3

  y = -8×1 +2 = -6 . . . . use the first equation to find y

The solution is (x, y) = (1, -6).

Answer:

363 feet because the elevator travels at a speed of 33 feet per second.

Step-by-step explanation:

330ft = 10 seconds

Divide both sides by 10

33ft = 1 second

now we know that the elevator travels 33 ft per second

To find how far does the elevator travel in 11 seconds,multiply both sides by 11

33ft = 1 seconds

363ft = 11 seconds

Answer:

When x = 12, y = 4, and z = 2, 8x + 2yz = 112.

Step-by-step explanation:

8x + 2yz

Substitute variables given:

x = 12

y = 4

z = 2

8(12) + 2(4)(2)

Multiply 8 and 12.

96 + 2(4)(2)

Multiply 2 and 4.

96 + 8(2)

Multiply 8 and 2.

96 + 16

Add 96 and 16.

112.

Answer:

[tex] = > 8(12) + 2(4)(2)[/tex]

[tex] = > 96 + 8(2)[/tex]

[tex] = > 96 + 16[/tex]

[tex] = > 112[/tex]

Answer:

im pretty sure its equivalent

Step-by-step explanation:

for 3/5 you would do 3*6 which equals 12

and for 5 you would do 5*4 which equals 20

and 3/5 is equivalent to 12/20

I might be wrong tho

your welcome :)

Raju can read one chapter 16 minutes so in if you divide 64 by 16 you get 4 meaning he can read 4 chapters in 64 minutes.

An isosceles triangle is one which has two equal sides and angles. Therefore, the measure of <NMO required in the given question is [tex]20^{o}[/tex].

An isosceles triangle is a type of triangle which has two equal sides, thus angles.

So that comparing the triangles in the given question, we have:

i. ΔNMQ, ΔMPQ, ΔOPM, and ΔNMO are all isosceles triangles.

Thus;

<MQN = <MNQ = [tex]60^{o}[/tex] (isosceles triangle base angle property)

So that;

<QMN = [tex]180^{o}[/tex] - (<MQN + <MNQ)

           = [tex]180^{o}[/tex] - [tex]120^{o}[/tex]

<QMN = [tex]60^{o}[/tex]

ii. In triangle MOP, we have;

<MPO = <MOP = [tex]80^{o}[/tex] (base angle property of isosceles triangle)

Then,

<PMO = [tex]180^{o}[/tex] - ([tex]80^{o}[/tex] +

        = [tex]180^{o}[/tex] - [tex]160^{o}[/tex])

<PMO = [tex]20^{o}[/tex]

But,

<QMP + <NMO = ([tex]60^{o}[/tex] - [tex]20^{o}[/tex])

                         = [tex]40^{o}[/tex]

Since <QMP = <NMO, then;

m<NMO = [tex]\frac{40^{o} }{2}[/tex]

              = [tex]20^{o}[/tex]

Thus, the measure of <NMO is [tex]20^{o}[/tex].
