Answer:

(0.4,6.2)

Step-by-step explanation:

set the equations equal, 3x+5=8x+3

solve for x, 5x=2, x=2/5 = 0.4

plug in x value to solve for y, y = 3*0.4 + 5, y=6.2

Please Hurry) What is the length of side AC of the triangle? □ units.

NARA [144]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

$\boxed{\mathrm{AC = 25 \:\: units ~}}$

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

As we can see in the given figure, Angles A and B are equal. therefore their opposite sides will be equal to one another, that is ~

AB = BC

now, let's plug the values of AB and BC in terms of x and equate them to find the value of x ~

$5x + 5 = 7x - 1$

$7x - 5x = 5 + 1$

$2x = 6$

$x = 6 \div 2$

$x = 3 \: \: units$

now , let's find the measure of side AC ~

AC = 6x + 7

that is ~

$6(3) + 7$

$18 + 7$

$25 \: \: units$

Find the slope of the line please

djyliett [7]

The slope of the line is 4/1.

An easy way to find the slope of a line is something called "rise-over-run." From the lowest point, how many spaces does it have to move up in order to be horizontally-on-the-line with the highest point? 4.

How many spaces across? 1...

4 = rise

1 = run

4 RISE

-- -------

1 RUN
