We want to solve the inequalities
x < 2
y ≤ 4x + 1

<span>Graph </span>the lines:
x = 2
y = 4x +1

The solution to the system of inequalities is the shaded region shown in the graph below.

Test the given points to see whether they fall within the solution region.

Point   Pass/Fail
--------  --------------
(5,6)     Fail
(5,-2)    Fail
(-3,-15)  Pass
(1,11)       Fail

Answer: (=3, -15)

Write the equation of a line in slope-intercept form that is parallel to the line y equals 7 over 8 x minus 7 and containing poi
STALIN [3.7K]

Answer:

y = (7/8)x + 7

Step-by-step explanation:

"7 over 8 x" is incorrect; you meant "(7/8)x" (which is not the same as "7 over 8 x."  Thus, your line is y = (7/8)x - 7.  The slope of a parallel line is the same, or (7/8).  Given that the line passes thru (8,0), we have enuf info with which to calculate the y-intercept.  Write out:  y = mx + b.  Immediately replace m with (7/8), y with 0 and x with 8, obtaining:  0 = (7/8)(8) + b.  Then b = 7, and the equation of this new, parallel, line is y = (7/8)x + 7.

Solve the system by submission -5y-10=x<br> x+9y=-2
Sonbull [250]

Answer:  =−20

y=2

​

Step-by-step explanation:

Solve for xx in -5y-10=x−5y−10=x.

x=-5y-10

x=−5y−10

2 Substitute x=-5y-10x=−5y−10 into x+9y=-2x+9y=−2.

4y-10=-2

4y−10=−2

3 Solve for yy in 4y-10=-24y−10=−2.

y=2

y=2

4 Substitute y=2y=2 into x=-5y-10x=−5y−10.

x=-20

x=−20

5 Therefore,

\begin{aligned}&x=-20\\&y=2\end{aligned}

​

 

x=−20

y=2
