Answer:

\fbox{x = 9, y = 12}

Step-by-step explanation:

\textsf {Let's solve by substitution.}

\rightarrow \mathsf {-5x + 4y = 3}\\\rightarrow \mathsf {x = 2y - 15}

\textsf {Substitute for x in the first equation of the system.}

\implies \mathsf {-5(2y-15)+4y=3}

\implies \mathsf {-10y+75+4y=3}

\implies \mathsf {-6y=-72}

\implies \textbf {y = 12}

\implies \mathsf {x = 2(12) - 15}

\implies \mathbf {x = 9}

\textsf {The solution is : x = 9, y = 12}

marissa [1.9K]

Answer:

d(m) = (1.05 miles/min)*m

Step-by-step explanation:

Divide 2 5/8 miles by 3 1/2 minutes to obtain the unit rate (miles per minute):

2 5/8 miles

--------------------

3 1/2 minutes


First, convert 2 5/8 miles and 3 1/2 minutes to improper fractions:

21/8 miles             21/8 miles

------------------  =  ----------------------  =  21/20 miles/minute

5/2 minutes         20/8 minutes


The constant rate is (21/20) miles/minute, or 1.05 miles/minute.

Thus, the equation representing the distance, d, that the car travels in m minutes is

d(m) = (1.05 miles/min)*m

What is the slope of the line through (1, -1) and (5. – 7)?
Vladimir [108]

Answer:

-3/2

Step-by-step explanation:

Given two points, we can find the slope by

m = (y2-y1)/(x2-x1)

    = (-7 - -1)/ (5-1)

    = (-7+1)/(5-1)

    = -6/4

    = -3/2
