Find the solution of the system of equations.
2.x + 4y = -14
– 2y = 9

Answers

Answer:

x = 4, y = -9/2 (-4.5)

Step-by-step explanation:

Using the second equation, we can divide both sides by -2 and get

y = 9/-2

y = -9/2

Then, we plug this y value into the first equation and get:

x + 4(-9/2) = -14

Simplify:

x - 18 = -14

x = 4

F(x)=x2 -x and g(x)=12-x2

Find the slope of the line
(15,18) (6,12)

Answers

Answer:

slope = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (15, 18 ) and (x₂, y₂ ) = (6, 12 )

m = [tex]\frac{12-18}{6-15}[/tex] = [tex]\frac{-6}{-9}[/tex] = [tex]\frac{2}{3}[/tex]

Remember, when finding the slope, use this formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]

We can start by labeling (15, 18) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex] and (6, 12) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now, we can plug these number into the formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }=\frac{12-18}{6-15}=\frac{-6}{-9} =\frac{2}{3}[/tex]

Thus, the slope of the line is [tex]\frac{2}{3}[/tex]. Hope this helps! Let me know if you have any questions related to this problem.

Answers

Answer:

3/4 * 120 = 90

Step-by-step explanation:

3/4 of something is the same as multiplying by 0.75 (to do it one way.)

Or you can just divide 120 by 4, then multiply it by 3.

EDIT: I see you're asking for 3/4, then 3/8...

Ok so first, we know just by looking that QT is 180° since it’s a fraught angle. If you subtract angle QRS from QT, you’ll get the value for angle SRT. 180-162 is 18 so SRT IS 18°. The other angle of the triangle is already given to us as 130°. Since all three angles of a triangle add up to 180°, we can subtract the two angles to get the remaining one. 180-130-18 is 32 so the missing angle is 32°
Hope this helped :)

Answer:

Step-by-step explanation:

Hi there!

∠SRQ = 162°

∠STR = 130°

∠RST = ?

Now;

∠SRQ = ∠RST+∠STR   [external angle is equal to the sum of opposite interior angles of triangle]

∠RST = ∠SRQ-∠STR

∠RST = 162°-130°

Therefore, the measure of ∠RST is 32°.

What is the y-intercept of the equation 2x + 4y = -16?
1. -16
2. -8
3. -4
4. -2

Answers

Answer:

3) -4

Step-by-step explanation:

Hi there!

2x + 4y = -16

The y-intercept occurs when x=0. Replace x with 0 and solve for y:

2(0) + 4y = -16

4y = -16

y = -4

Therefore, the y-intercept is -4.
