Solve the equation for the red variable

Answer:

3

Step-by-step explanation:

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

Given:

The graph of a proportional relationship contains the point (8,4).

To find:

The corresponding equation.

Solution:

If y in directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]        ...(i)

Where, k is the constant of proportionality.

The graph of a proportional relationship contains the point (8,4).

Putting x=8 and y=4 in (i), we get

[tex]4=k(8)[/tex]

[tex]\dfrac{4}{8}=k[/tex]

[tex]\dfrac{1}{2}=k[/tex]

Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get

[tex]y=\dfrac{1}{2}x[/tex]

Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].

Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

Answer:

It’s A

Step-by-step explanation:

Answer:

86 or 32, depending on the correctness of the syntax

Step-by-step explanation:

We use PEMDAS:

Parentheses: 4(2)5 2-6/(-3)

Exponents: I'm assuming that all the syntax is correct (so no exponents).

Multiplication and Division: 40*2+6 = 80 + 6

Addition and Subtraction: 86

If you copy+pasted this expression, then the original equation would have been: (4(8 − 6)^5)/(2 − 6 ÷ (−3)). We can use PEMDAS:

Parentheses: (4(2)^5)/(2 - 6 ÷ (−3))

We now have the following fraction: 128/4

That simplifies to 32

Answer:

Lowest: 78

Highest: 99

Step-by-step explanation:

Quiz 1 =A

Quiz 2 = B

B = 21 + A

2A = 57 + B

2A = 57 + (21 + A)

2A = 78 + A

A = 78

B = 21 + A

B = 21 + 78

B = 99

Answer:

Step-by-step explanation:

17. Rotation

18. Always

19. 4

20.

21. Acute triangle/ Isosceles triangle. All angels are acute and there are none of the sides are equal.

22. The transformation was a reflection. I know this because all the colors flipped, but everything else is the same.

Answer:

17. rotation

18. never

19. 4

20. The third one

21. It is an acute ASA triangle because all of the angles are less then 90 degree and since you are given the sides as well, it is ASA.

22. A rotation was used, because the colors are rotated 90 degrees, even though the shape itself stays the same.

Answer:

708.56 ft

Step-by-step explanation:

Use the tangent trig rule, TOA in SOH-CAH-TOA. Take your opposite, h, and divide it over your adjacent, 875. Then take the tangent of 39° using a calculator, and multiply 875 on both sides to get h by itself, that being the result of 708.56 ft rounded.

24x - 16 is the answer!

Explanation:

Area of a rectangle = length x breadth

Therefore, Area of the given rectangle will be; 8 (3x-2)

= 24x - 16.

Answer:

45

Step-by-step explanation:

First we want to understand the Base Angles Theorem

The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.

Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.

We can create the equation ∠N + ∠A + ∠G = 180 degrees.

Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into

90 + 2x = 180

We can then solve for x,

90 + 2x - 90 = 180 - 90

2x = 90

2x / 2 = 90 / 2

x = 45 degrees

Answer: 87.9

Step-by-step explanation:

Since the formula is 2 x pi x radius x height, we plug the equation in.

If you use “3.14” for pi, it’s 2 x 3.14 x 7 x 2 = 87.9 (rounded to the nearest tenth)

2 x pi x 7 x 2 = 87.96 (88 rounded to the tenth)

Answer:

10 tacos

Step-by-step explanation:

10 tacos is the better deal because

it is 0.85 cents. 0.85 x 10 = $8.50 per taco for 10 tacos while it would cost $0.90 per taco for 6 tacos

0.90 x 6 = 5.40.

Hope this helps.
