Y=6x/5 +27 find y-intercept and slope

mixas84 [53]

Answer:

General equation of a line is given by y = mx +c, where m is the gradient /slope, c is the intercept. To find for the intercept on y- axis, put x = 0.
$y = \frac{6(0)}{5 } + 27 \\ y = \frac{0}{5} + 27 \\ y = 27 \\ therefore \: the \: intercept \: on \: y \: is \: 27 \\$
By comparison,
$y = mx + \: c \\ y = \frac{6}{5} x \: +27 \\ m = \frac{6}{5 \: } \: \\ hence \: slope \: is \: \frac{6}{5}$

1 4/8 in a improper fraction?

stiv31 [10]

<h2>Answer: $\frac{3}{2}$ <u><em></em></u></h2>

Step-by-step explanation:

Step 1: Multiply the whole number part (1) by the denominator (8).

1 × 8 = 8

Step 2: Add the product from Step 1 (8) to the numerator (4).

8 + 4 = 12

Step 3: Write that result (12) above the denominator. So,

$\frac4{8}{1}$

Step 4: The fraction $\frac{12}{8}$

Can be reduced by dividing both numerator and denominator by the GCD(12,8) = 4. Thus,

$\frac1{4}{8} =\frac{3}{2}$

A rectangular television screen has an area of w^2 + 2w square inches if the width of the television screen is w inches, what is

gregori [183]

The area of a rectangle is:

A = length × width

A rectangular television screen has an area:

A = w² + 2w inches²

width = w

length = A / width = (w² + 2w) / w = w(w + 2) / w = <u>w + 2</u>

Ansver:

<h2><u>length = w + 2</u></h2><h2><u></u></h2><h2><u></u></h2>
