Answer:

x=5 and y=25

Step-by-step explanation:

y=5x

3x+10=5x

3x+10+−5x=5x+−5x(Add -5x to both sides)

−2x+10=0

−2x+10+−10=0+−10(Add -10 to both sides)

−2x=−10

−2x

−2

=

−10

−2

(Divide both sides by -2)

x=5

y=3x+10

y=(3)(5)+10

y=25(Simplify both sides of the equation)

Why do airplanes look like they are going slower when they are higher in the sky?
dlinn [17]
Our brains judge the speed of objects passing by us through the time taken for them to cross our field of view. Those taking a long time could either be nearby and travelling slowly or faster and further away. And in the case of planes, our brains know that the second interpretation is the right one.

K (t) = 13t - 2; k(3)
True [87]

Answer:

k(3)=37

Step-by-step explanation:

This questions asks us to find k(3).

We want to find what k(t), or y is, when t, or x is equal to 3.

k(t)=13t -2

Therefore, we can substitute 3 in for t.

k(3)= 13(3)-2

Solve according to PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, multiply 13 and 3

k(3)=39-2

Subtract 2 from 39

k(3)=37
