Answer:

We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

[tex]y = mx+b[/tex]

where

Important Tip:

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

[tex]18x + 9y = -416[/tex]

subtract 18x from both sides

[tex]18x+9y-18x = - 18x-416[/tex]

simplify

[tex]9y = -18x - 416[/tex]

divide both sides by 9

[tex]y=-2x-\frac{416}{9}[/tex]

Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation

Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.

Hence, option D is correct.

Answer: 3n+21

Step-by-step explanation: it’s the distributive property so you multiply the number outside the parentheses times the numbers or number inside the parentheses

Answer:

3n+21

IF the question required =0 then move the 21 to the other side

and divide both sides by 3 and x would equal to -7

Step-by-step explanation:

3(n+7)

use the distributive property, so multiply 3 with n and 7

3n+21

Answer:

x = 4

y = 3

Step-by-step explanation:

2x - 3(x - 1) = -1

2x - 3x + 3 = -1

-x + 3 = -1

   - 3     - 3

(-1) -x = -4 (-1)

x = 4

y = 4 - 1

y = 3

x = 4, and y = 3

Answer: 18 pies, 22 cakes

Step-by-step explanation:

Let the number of pies sold be represented by p.

Let the number of cakes be represented by c.

The information in the question can then be represented in an equation as:

p + c = 40 ........ i

10p + 8c = 356 ....... ii

Multiply equation i by 10

Multiply equation ii by 1

10p + 10c = 400 ....... iii

10p + 8c = 356 ....... iv

Subtract iv from iii

2c = 44

c = 44/2

c = 22

22 cakes were sold

Since 40 items were sold, the number of pies sold will be:

= 40 - 22

= 18 pies

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

Answer:

y=1

Step-by-step explanation:

Let's solve your equation step-by-step.

5(2y−3)−4y=8−2y−15

Step 1: Simplify both sides of the equation.

5(2y−3)−4y=8−2y−15

(5)(2y)+(5)(−3)+−4y=8+−2y+−15(Distribute)

10y+−15+−4y=8+−2y+−15

(10y+−4y)+(−15)=(−2y)+(8+−15)(Combine Like Terms)

6y+−15=−2y+−7

6y−15=−2y−7

Step 2: Add 2y to both sides.

6y−15+2y=−2y−7+2y

8y−15=−7

Step 3: Add 15 to both sides.

8y−15+15=−7+15

8y=8

Step 4: Divide both sides by 8.

The value of y is 1

Given the equation 5(2Y - 3) – 4y = 8 – 2y - 15

Expand

10Y - 15– 4y = 8 – 2y - 15

6y - 15 = -7 - 2y

Collect the like terms

6y + 2y = -7 + 15

8y = 8

Divide both sides by 8

8y/8 = 8/8

y = 1

Hence the value y of is 1

Step-by-step explanation:

It can also be written in exponential form as 21 x 52 x 71.

Answer:

Step-by-step explanation:

draw the prime factor tree of 350

you can choose any 2 numbers that equals 350, then continue in that way by choosing any 2 numbers that equals the number that's on top of the 2 other numbers when multiplying, except 1×number, because it won't help you to get the prime factors of a specific number, unless it's a prime number so you don't need to multiply by any number

                                                             350

Answer:

Ruby needs 7 combined.

Step-by-step explanation:

If she needs 1/4 cup of powdered milk for one batch, then we multiply 1/4 by 4 to see how much she needs for 4 batches, which is 4/4, or one whole.

If she needs 3/2 cups of whole wheat for one batch, then we multiply 3/2 by 4 to see how much she needs for 4 batches, which is 12/2, or 6.

Then we combine 6 and 1, which is 7.
