Paralelll ines have same slope
in form
ax+by=c
slope=-a/b

point slope form
the equtaiotn of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
find slope

24x+8y=7
slope=-24/8=-3

a point is (-5,-8)

m=-3

y-(-8)=-3(x-(-5))
y+8=-3(x+5)
y+8=-3x-15
y=-3x-23

Solve this system of linear inequalities ( will give brainiest)

lakkis [162]

From the graphs you can see that the graph of the line $y= \frac{1}{3} x-3$ lies under the graph of the line $y= \frac{1}{3} x-1$ . Then all solutions of unequality $y\le \frac{1}{3} x-3$ are solutions of unequality $y\le \frac{1}{3} x-1$ , but not all solutions of unequality $y\le \frac{1}{3} x-1$ are solutions of unequality $y\le \frac{1}{3} x-3$ .
For example, if x=1, y=-2
$-2\le \frac{1}{3} \cdot 1-1 =- \frac{2}{3} \\ -2\ \textgreater \ \frac{1}{3} \cdot 1-3=- \frac{8}{3}$ .
Answer: Correct choice is B.

Can someone help me me I think I'm bad at this honestly..

Answer:

A=7.07cm^2

Step-by-step explanation:

A= (pi)(r^2)

diameter=3

radius= 1/2 of the diameter = 1.5

pi = approximately 3.14

A= (3.14) (1.5)^2

A= 7.065 ----> rounds to 7.07
