Answer:

(-18, -3)

Step-by-step explanation:

To solve this system of equations, use the substitution method.

Steps for substitution method:

Step 1 : First, solve one linear equation for y in terms of x.

Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x.

Step 3: Solve this, and you have the x -coordinate of the intersection.

Step 4: Then plug in x to either equation to find the corresponding y -coordinate.

Please help me!!!! I will mark brainlist.
Misha Larkins [42]

Answer:

angle 1 =135

Step-by-step explanation:

it is 180 degrees total. We know that there are two angles that have a ratio to 3:1. So, assign x to 2. Since 1 = 3x, we do 3x+x =180

4x=180

x=45 or angle 2

180-45=135 or angle 1

Multiply angle 2 by 3 to check if its correct

Evaluate the expression StartFraction 12 minus 3 y Over 2 EndFraction plus y StartFraction 2 y minus 4 Over y EndFraction for y
vladimir1956 [14]

Answer:\frac{31}{6}

Step-by-step explanation:

Given

\Rightarrow \frac{12-3y}{2}+y\frac{2y-4}{y}

\Rightarrow \frac{12-3y}{2}+\frac{y^2+2y-4}{y}

Now for y=3

\Rightarrow \frac{12-3\times 3}{2}+\frac{3^2+2\times 3-4}{3}

\Rightarrow \frac{3}{2}+\frac{9+6-4}{3}

\Rightarrow \frac{3}{2}+\frac{11}{3}

\Rightarrow \frac{9+22}{6}=\frac{31}{6}

20 POINT'S!!!!!!!!!<br> HELP!!!
zalisa [80]

Well, the base and height would still be applicable (essentially, base is just width and height is just, uh, height,)

So basically the area of one triangle is 0.5(7*6), which is 21

The area of one triangle is option c., 21.
