Answer:

4y + 28

Step-by-step explanation:

I simply distributed the 4:

1. 4(y+7)

2. 4 times y = 4y

3. 4 times 7 = +28

4. 4y + 28

Answer:

4y + 24

4 * y + 7 * 4

Any of those two ^

Step-by-step explanation:

We are asked to expand 4(y+7), expanding is making an equation a bit longer, in this case, we can distribute the 4 to both values within the parenthesis.

4 multiplied to y is 4y, and 4 multiplied by 7 is 24. This will get you 4y + 24, because you cannot add a number with a variable to a number without one.

If that isn't enough, just don't multiply the 7 and the 4.

Giving you 4 * y + 7 * 4

If a coin is tossed and a number cube is rolled what is the probability of getting heads and the number cube shows 3?
Maurinko [17]

Answer:

1/12

Step-by-step explanation:

Since the probability of getting heads is 1/2 and the probability of the number cube getting three is 1/6, we multiply.

For every coin flip, there is a 1/6 chance of getting a three. But since there is another condition, we have to multiply. Multiplying both fractions make 1/12.

What are the solutions to the system of equations <br> {-x+y=4<br> {y+12=x^2+x
Gnoma [55]

Answer:

Step-by-step explanation:

y=4+x          ............................................ (1)

y=x^2+x-12  ............................................ (2)

now equate both (1) and (2)

4+x=x^2+x-12

=>x^2=16

x=-4,4

now substitute the values of x ,

when x=-4 , y becomes 0

when x=4  , y becomes 8

so, solution set:

(-4,0) and (4,8)

What is g(3) when g(x) = 4x^2-3x+7
Misha Larkins [42]

Answer:

34

Step-by-step explanation:

g(x) = 4x^2 - 3x + 7

g(3) = 4(3)^2 - 3(3) + 7

g(3) = 4(9) - 9 + 7

g(3) = 36 - 9 + 7

g(3) = 27 + 7

g(3) = 34

Best of Luck!

Complete the following equation using &lt;, &gt;, or = 120% ___ 1
kvasek [131]
To solve these types of problems, we need to convert the two values into the same form.  

We know that 1 = 1.00, as adding zeroes to the end of a decimal doesn't change the value.

To change a decimal into a percentage, we multiply the decimal by 100 and add a percent sign.  

1.00 * 100 = 100%

Therefore, 1 = 100%

Because 120% is greater than 100%, thus, 

120% > 1
