anybody know this one? kinda confused lol

Answer:

y=13

Step-by-step explanation:

12-y=-1

-y=-13

y=13

Answer:

Step-by-step explanation:

Here you go mate

Step 1

x=4  

Step 2

3x-y=-1  Substitute 4 for x

(3)(4)-y=-1

-y=-13

Step 3

-y=-13  Divide both sides

answer

y=13

Answer:

A. 42 - 12

Step-by-step explanation:

6(7-2) = 6(5) = 30

A. 42 - 12 = 30

B. 13 - 8 = 5

C. 67 - 62 = 5

D. 7 - 2 = 5

Answer:

42-12

Step-by-step explanation:

I'll keep this short

You do distributive property so you do 6*7-6*2=42-12

GL, tell me if you have any questions

Given:

The table of values.

Hours (h)        Dollars (d)

     1                       42

     2                      84

     3                     126

     4                     168

     5                       ?

To find:

The correct statements about the table.

Solution:

From the given table it is clear that,

[tex]1\times 42=42[/tex]

[tex]2\times 42=84[/tex]

[tex]3\times 42=126[/tex]

[tex]4\times 42=168[/tex]

This pattern can be defined as

[tex]h\times 42=d[/tex]

Multiply h by 42 to get d. So, option A is correct.

Using this pattern, we get

[tex]5\times 42=210[/tex]

The missing value in the last row is 210. So, option D is correct.

From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.

A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”

Therefore, the option E is correct.

The answer is 599.20

Step-by-step explanation:

Answer: |18| is the greatest value.

Step-by-step explanation:

Answer:

An odd number times an even number is always even

e.g 2 × 3 = 6

4 × 5 = 20

adding 1 to an even number makes it odd

6 + 1 = 7

20 + 1 = 21

hope this helps...

Answer:

P is an odd number

Q is an even number

Now, product of a odd number and even number is always even number.

Therefore, P×Q is a even number

Now, by adding 1 to the even number it becomes odd.

Hence, P×Q+1 is always an odd number.

Answer:

C

Step-by-step explanation:

A linear function will have a constant rate of change. The rate of change (or slope) for C is -3. All the other graphs do not have a constant rate of change. As in the difference between each value was different.

Answer:

The weight of a giant panda = x = 200 pounds

The weight of a red panda = y = 20 pounds

Step-by-step explanation:

Let

The weight of a giant panda = x

The weight of a red panda = y

The weight of a giant panda is 10 times the weight of a red panda.

x = 10y

The combined weight of the pandas is 220 pounds.

x + y = 220

We substitute 10 y for x

10y + y = 220

11y = 220

y = 220/11

y = 20 pounds

Solving for x

x = 10y

x = 10 × 20

x = 220 pounds

Hence:

The weight of each panda is:

The weight of a giant panda = x = 200 pounds

The weight of a red panda = y = 20 pounds

Answer: c.) 0.04a + 0.06b + 0.05c = 950

Step-by-step explanation:

To find interest per investment you need to multiply the percentage interest rate by the value of the investment.

When written in linear equations, percentages are converted to decimal form.

4% = 1/100 = 0.04

6% = 6/100 = 0.06

5% = 5/100 = 0.05

These are the interest rates that when multiplied by their investments, will give a total of $950.

0.04 * a + 0.06 * b + 0.05 * c = 950

0.04a + 0.06b + 0.05c = 950

Option c is therefore correct.

Answer:

D. One solution

Step-by-step explanation:

Simplify:

[tex]6-3x = 12-6x\\-3x+6x = 12-6\\3x = 6\\x = 2[/tex]

There is only one solution (x=2) that satisfy the equation.

Answer:

8

Step-by-step explanation:

400 divided by 50 is 8

Answer:50

there are 400 students and a bus can hold 50 so you divide 400 by 50 which is equel to 8

so about 50 kids if all the kids go on the bus

Answer:

The answer is 4,492,369.

Step-by-step explanation:

First of all, how the HECK do you have 5 MILLION MARBLES?! Make the equation for the problem: 5049349 - 545000 + 45000 - 56980.

5049349 - 545000 + 45000 - 56980

4504349 + 45000 - 56980

4549349 - 56980

4492369

Answer:

A.

Step-by-step explanation:

It should be A. since if you have value that is greater than 1 then the graph would get narrower if you change the a value so this crosses E. out of the list

Answer:

64

Step-by-step explanation:

Answer:

22.5 miles 1/2 hour - 45 miles 1 hour - 67.5 miles 1.5 hours - 135 miles 3 hours

Step-by-step explanation:

If Lily travels 90mph in 2 hours she would travel 45mph each hour. So now just take 45 times 1, 1.5, and 3 to get your answers. So in half an hour she would travel 22.5 miles

Answer:

8g = 12 + 28

g = 5 packs

Step-by-step explanation:

Share of the sticks of gum

Manuela = 12 sticks

Sinah = 28 sticks

There are 8 sticks in each pack

g = number of packs of gum that sinah bought?

g × 8 sticks = 12 sticks + 28 sticks

8g = 40

Divide both sides by 8

g = 40 / 8

g = 5 packs

Answer:

solve m+5=4m-10 to find the value of m

Step-by-step explanation:

Answer:

Part A)

An equation in​ point-slope form for the line having the slope m = 6 and containing the point (7,2).

[tex]y - 2 = 6(x-7)[/tex]

Part B)

An equation in​ point-slope form for the line having the slope m = -4 and containing the point (1, 9).

[tex]y - 9 = -4(x-1)[/tex]

Step-by-step explanation:

                                                        Part A)

Given

Slope m = 6

Point (7, 2)

To Determine

Find an equation in​ point-slope form for the line having the slope m = 6 and containing the point (7,2).

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case:

substituting the values m = 6 and the point (x₁, y₁) = (7, 2) in the point-slope form of line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 2 = 6(x-7)[/tex]

Therefore, an equation in​ point-slope form for the line having the slope m = 6 and containing the point (7,2).

[tex]y - 2 = 6(x-7)[/tex]

                                                       Part B)

Given

Slope m = -4

Point (1, 9)

To Determine

Find an equation in​ point-slope form for the line having the slope m = -4 and containing the point (1, 9).

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case:

substituting the values m = -4 and the point (x₁, y₁) = (1, 9) in the point-slope form of line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 9 = -4(x-1)[/tex]

Therefore, an equation in​ point-slope form for the line having the slope m = -4 and containing the point (1, 9).

[tex]y - 9 = -4(x-1)[/tex]

The answer is:

1) y - 2 = 6(x - 7)

2) y - 9 = -4(x - 1)

Work/explanation:

The point slope formula is:

[tex]\bf{y-y_1=m(x-x_1)}[/tex]

where m = slope;

(x₁, y₁) is a point on the line.

For this problem, m = 6 and the point is (7,2).

Plug in the data:

[tex]\bf{y-2=6(x-7)}[/tex]

__________________

For this problem, m = -4 and the point is (1,9).

Plug in the data:

[tex]\bf{y-9=-4(x-1)}[/tex]

Hence, these are the equations.
