Work out the gradient of a line that is parallel to -2x+y-5=0

gradient = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

Given

- 2x + y - 5 = 0 ( add 2x and 5 to both sides )

y = 2x + 5 ← in slope- intercept form

with gradient m = 2

Parallel lines have equal gradients

Gradient of parallel line is m = 2

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
