Where do lines modeled by equations y=-7/8x+1/4 and y=-3/4x+1/2 intersect

If they intersect they have the same x and y values so we can say y=y which can be expressed as:

-7x/8+1/4=-3x/4+1/2  make all terms have a common denominator of 8

-7x/8+2/8=-6x/8+4/8  now multiply all terms by 8

-7x+2=-6x+4  add 6x to both sides

-x+2=4  subtract 2 from both sides

-x=2  divide both sides by -1

x=-2, now we solve for y using either original equation...

y=-3(-2)/4+1/2

y=6/4+1/2

y=6/4+2/4

y=8/4

y=2  so the lines intersect at the point:

(-2, 2)

If you travel 90 miles in 1 ½ hours, what distances would you travel if you drove 6 hours?
sattari [20]

Answer:

360 miles

Step-by-step explanation:

If you travel 90 miles in 1 ½ hours, it will take 360 miles if you drove 6 hours.

All you have to do is, multiply 1 ½  until you get to 6.

The easiest way is:

1 ½ = 90 miles

1 ½ (90 miles) x 2 = 3 or 180 miles

3 (180 miles) x 2 = 6 or 360

Therefore, 6 hours = 360 miles.

so Commutative  Property means you can switch up

the numbers not the sign for example.

4 × 3 × x

4 × x × 3

3 × x × 4

x × 3 × 4

x × 4 × 3

if you look at all these! they just switch

this is easier like 4x5=20 in communicative property it would be 5x4=20

Hope this helps :)
