Answer 1

Answer:

(6, - 1 )

Step-by-step explanation:

Given the 2 equations

2x + y = 11 → (1)

[tex]\frac{1}{2}[/tex] x - 5y = 8 ← (2)

Multiplying (2) by - 4 and adding to (1) will eliminate the x- term

- 2x + 20y = - 32 → (3)

Add (1) and (3) to eliminate x

0 + 21y = - 21

21y = - 21 ( divide both sides by 21 )

y = - 1

Substitute y = - 1 into either of the 2 equations and solve for x

Substituting into (1)

2x - 1 = 11 ( add 1 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

solution is (6, - 1 )

A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes

Answers

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.

Which of these figures is NOT a quadrilateral?

Answers

Answer:

the correct answer is A

step by step explanation

Figure A is NOT a quadrilateral. Then the correct option is A.

What is a quadrilateral?

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees. In a quadrilateral, there are four vertices.

A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. In a rhombus, opposite sides are parallel and all sides are equal. In a parallelogram, opposite sides are parallel and equal.

Figure A is NOT a quadrilateral. Because two corners of the figure are rounded and in the quadrilateral, all the vertices are shaped.

Figure A is NOT a quadrilateral. Then the correct option is A.

After 10% tax, the phone cost $220. What was the original price?​

Answers

Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

A mailing supply company produces yellow mailing envelopes. The envelopes come in
a variety of sizes, but the length is always 4 centimeters more than double the width.
Write an equation to find the dimensions of an envelope that has a perimeter of 26
centimeters.

Answers

Answer:

Step-by-step explanation:

L=2W+4

P=2(L+W), using L from above makes this

P=2(2W+4+W)

P=2(3W+4)

P=6W+8

6W=P-8

W=(P-8)/6, since we are told P=26

W=(26-8)/6

W=18/6

W=3 cm, and since L=2W+4

L=2(3)+4

L=6+4

L=10 cm

So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm

Answer:

g(x) = [tex]2^{x}[/tex] + 3

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 3 units up, then

g(x) = [tex]2^{x}[/tex] + 3
