John's suv gets 18 miles per gallon (mpg). this is half as many mpg as his wife's hybrid car. how many miles per gallon does the hybrid car get?

The hybrid car gets 36 miles per gallon (mpg).

Step-by-step explanation:

It is given that John's SUV gets 18 miles per gallon (mpg). This is half as many mpg as his wife's hybrid car.

Let the hybrid car gets x miles per gallon (mpg).

Since the John's SUV miles per gallon (mpg) is half as many mpg as his wife's hybrid car.

Multiply both sides by 2.

Therefore the hybrid car gets 36 miles per gallon (mpg).

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
