Step-by-step explanation:

find the slope of line from the two points given. (0,0) and (4,3) which is y=3/4 x.

What is the combined length of all the buttons longer than 1 inch

muminat

Answer:

$2\frac{1}{2}$ inches

Step-by-step explanation:

The "x" represents the number of buttons.

There are 2 sizes longer than 1 inch:

$1\frac{1}{8}$ in and $1\frac{1}{4}$ in

There are NO 1 1/8 inch buttons

THere are two 1 1/4 inch buttons

Hence the combined length would be:

$1\frac{1}{4}+1\frac{1}{4}=2\frac{2}{4}=2\frac{1}{2}$ inches

A point located at (-5, 2) is translated right 3 units. What are the coordinates of the image? (-5, 5) (-2, 5) (-5, -1) (-2, 2)

Mazyrski [523]

ANSWER

(-2,2)

EXPLANATION

The rule for translating a point 'k' units to the right is

$(x,y)\to (x+k,y)$

If the point located at (-5, 2) is translated right 3 units, the coordinates of the image is obtained by adding 3 to the x-coordinate.

This implies that,

$( - 5,2)\to ( - 5+3,2)$

$( - 5,2)\to ( -2,2)$

Therefore the image is:

(-2,2)
