The units of speed are miles per hour. You get that by dividing miles by hours:
  (270 mi)/(4.5 h) = 60 mi/h

Answer:

60 miles per hour

Step-by-step explanation:

The location you want to go is 270 miles away.

You want to cover this distance in 4.5 hours.

Formula to get  Speed=\frac{Distance}{Time}

Speed=\frac{270}{4.5} = 60 miles/hour

Unit of speed is miles per hour

You need to drive at 60 miles per hour.

which of the following represents the equation of the line with an x- intercept of 6 that passes through the point (4,4)?
luda_lava [24]

Answer:

y=-2x+12

Step-by-step explanation:

To write the equation of a line, find the slope between two points. Substitute two points into the slope formula. If the equation has an x-intercept of 6 then the line passes through the point (6,0). Use (6,0) and (4,4) in the formula.

m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-0}{4-6} =\frac{4}{-2} =-2

Since m = -2, substitute its value and the point (6,0) into the point slope form. Then simplify.

y-y_1 = m(x-x_1)\\y-0 = -2 (x-6)\\y=-2x+12

Solve the following system of equations <br> x^2+2y^2=59<br> 2x^2+y^2=43
aivan3 [116]

Answer: x = (-3,3), y = (-5,5)

Step-by-step explanation:

Add both of the equations together, for 3x^{2}+3y^{2} = 102. Now we can divide both sides by 3, gettingx^2+y^2=34. we subtract the first equation from our equation we just got, getting y^2=25 y= (5,-5). once we plug that in, we get 50+x^2 = 59, x^2 = 9 x = (-3,3)

What is an equation of the line that passes through the point (3, 3) and is parallel to
Lena [83]

Answer:

y=6x

Step-by-step explanation:

The formula you use is y=mx+b you get 4x-3y=21 you add 3 to 3y and 21 then you cancel out the 3's 4x goes down and then you add 21+3 which equals 24 then you divide it all by 4 except y, you drop the y down and you should get y=6x

Hope you get it right
