Answer:

Step-by-step explanation:

y = 3x + 4

Plugin x = 3 in the equation,

y = 3*3 + 4

 = 9 + 4

y = 13

Plugin x = 4 in equation,

y = 3*4 + 4

  = 12 + 4

y = 16

Plugin x = 5 in the equation,

y = 3*5 + 4

  = 15 + 4

y = 19

2) y =x - 7

Plugin x = 10 in the equation

y = 10 - 7

y = 3

Plugin x = 15 in the equation

y = 15 - 7

y = 8

Plugin x = 20 in the equation

y = 20 - 7

y = 13

1 5/7÷4/9 = what's the answer and how to write the problem out
balu736 [363]

The solution to given expression 1\frac{5}{7} \div \frac{4}{9} is \frac{27}{7} or 3.8571

<em><u>Solution:</u></em>

Given expression is:

1\frac{5}{7} \div \frac{4}{9}

<em><u>First let us convert the mixed fraction to improper fraction</u></em>

Multiply the whole number by the denominator.

Add the answer from Step 1 to the numerator.

Write answer from Step 2 over the denominator.

Thus we get,

1\frac{5}{7} = \frac{1 \times 7 + 5}{7} = \frac{12}{7}

Now the given expression becomes,

1\frac{5}{7} \div \frac{4}{9} = \frac{12}{7} \div \frac{4}{9}

Convert the problem to multiplication by changing the division sign to multiplication and inverting the fraction to the right of the sign

\frac{12}{7} \div \frac{4}{9} = \frac{12}{7} \times \frac{9}{4}

Multiply the numerators, multiply the denominators, and leave the product in factored form

\frac{12}{7} \times \frac{9}{4} = \frac{27}{7}

In decimal form we get,

\frac{27}{7} = 3.8571

Thus the solution to given expression is \frac{27}{7} or 3.8571

What is the general form of the equation of the line shown?
Nostrana [21]

Hey There!

The formula of the general form equation is

0 = Ax + By + C

As we look at the answer choices we see that the last choice best represents the correct answer.

x + y + 2 = 0

Best matches the formula given and therefore that would be the correct answer.

Thus, the answer would be x + y + 2 = 0

He hypotenuse of a right triangle is three times the length of one of the legs. the length of the other leg is 648‾‾‾‾√648 feet.
pantera1 [17]
Let length of  the hypotenuse = 3x and length of given leg be x feet.

then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81


so x = 9 and 3x = 27

Hypotenuse is 27 feet and the leg equals 9 feet.
