Is (-6, 22) a solution to y= -3x +4 ?

Yes

Step-by-step explanation:

To find if (-6,22) is a solution to y=-3x+4, we can directly plug in the coordinates.

22=-3(-6)+4       [multiply]

22=18+4            [add]

22=22

Since 22=22, we know that (-6,22) is a solution to y=-3x+4.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
