What type of lines are these? y = 2x + 4 and 2y = -4x + 10

ANSWER

The lines are two intersecting lines. They intersect` at the point

EXPLANATION

To determine which type of lines, we look for the slopes of the two lines and compare them to see whether they are parallel or perpendicular.

The first line is .

This line is already in the form;

, which is referred to as the slope intercept form, where is the slope.

The second line is

Dividing through by 2 gives;

This implies that, this line also has a slope of .

Since the two slopes are not the same,the lines are not parallel.

Also the the product of the two slopes, , hence the two lines are  not perpendicular.

Adding equation (1) and (2) gives;

Putting in  equation (1) gives

.

Hence the two lines intersect` at the point

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
