Answer: 7/4

Step-by-step explanation:

you would first add 5 to both sides

4x-5+5= -12+5

then simplify

4x= -7

divide 4 on both sides

4x/4= -7/4

and you get x=7/4

Answer:

The answer to your question is:

x = 2

y = 4

Step-by-step explanation:

     4x - 5y = -12       (1)

      -x + 5y = 18        (2)

Solve the system

                                               4x - 5y = -12

                                                 -x + 5y = 18

                                              3x   + 0 = 6

                                               3x = 6

                                                  x = 6 / 3

                                                  x = 2

                  Substitution

                                     4(2) - 5y = -12

                                      8 -5y = -12

                                          -5y = -12 - 8

                                          -5y = -20

                                           y = -20 / -5

                                           y = 4

the altitude of A (in feet) of a plane T minutes after liftoff is given by a=3400t + 600. How many minutes after liftoff is the
____ [38]

If our equation is a = 3400t + 600, and we have a target altitude of 21,000, we just need to plug that in for a.

21,000 = 3,400t + 600. Now subtract 600 from both sides.

20,400 = 3,400t. now divide both sides by 3,400.

6 = t.

We get that our answer is at 6 minutes we get an altitude of 21,000 feet!

The line that contains the point Q( 1, -2) and is parallel to the line whose equation is y - 4 = 2/3 (x - 3)
Musya8 [376]

Answer:

y + 2 = \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = \frac{2}{3}(x - 3) ← is in point- slope form

with slope m = \frac{2}{3}

Parallel lines have equal slopes, thus equation of parallel line

with m = \frac{2}{3} and (a, b) = Q(1, - 2) is

y - (- 2) = \frac{2}{3}(x - 1) , that is

y + 2 = \frac{2}{3}(x - 1)
