Find the midpoint of a segment with endpoints (-9, 3) and (5, 7).
I need help ASAP pleasee
Answer:
( -2,5)
Step-by-step explanation:
To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2
( -9+5)/2 = -4/2 = -2
To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2
( 3+7)/2 = 10/2 = 5
The midpoint is ( -2,5)

a.5
b.21
c.17 over 5
4 over 5
Answer:
k = 5
Step-by-step explanation:
4 - 5k = -21
Transpose and subtract 4 from both sides:
4 - 4 - 5k = -21 -4
-5k = -25
Divide both sides by -5
-5k/-5 = -25/-5
k = 5

Answer:
[tex]\huge\boxed{66.42 \textdegree}[/tex]
Step-by-step explanation:
In order to solve for this missing angle, we can use trigonometry.
With angle B, we only have two sides: the adjacent of the angle and the hypotenuse of the angle. The adjacent side is the one laying directly next to the angle that isn't the hypotenuse.
Using SOH CAH TOA, we can see that the correct trig function for this would be cos because of CAH (Cosine = Adjacent over Hypotenuse)
Since we know the length of the sides but we don't know the angle, we are going to use inverse trig.
The adjacent side over our hypotenuse will be [tex]\frac{2}{5}[/tex] since 2 is the length of the adjacent and 5 is the length of the hypotenuse.
We know have the equation [tex]cos^{-1}(B) = \frac{2}{5}[/tex].
We now find what [tex]\frac{2}{5}[/tex] is (0.4) and find the inverse cosine of it. We can do this by plugging it into a calculator.
When we do this, we get the number [tex]66.42182152[/tex] etc. Rounding to the nearest hundredth gets us 66.42.

Where is the shading in the graph of the quadratic inequality y > -22 + 6x + 3? Why?
Answer:
Check Graph below
Step-by-step explanation:
y > -22 + 6x + 3
Add -22 and 3.
y > 6x - 19
Use the slope-intercept form to find the slope and y-intercept.
Slope: 6
y-intercept: (0,-19)
Graph a dashed line, then shade the area above the boundary line since y is greater than 6x − 19 .
y > 6x - 19

What is 5x-7(x+1)=9
Thanks for the help
Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
5x - 7(x + 1) = 9
Step 2: Solve for x
Distribute -7: 5x - 7x - 7 = 9Combine like terms: -2x - 7 = 9Add 7 to both sides: -2x = 16Divide both sides by -2: x = -8Step 3: Check
Plug in x to verify it's a solution.
5(-8) - 7(-8 + 1) = 9
-40 - 7(-7) = 9
-40 + 49 = 9
9 = 9
How to get the LCM of the exxpresion
Answer:
The LCM is made by multiplying all factors included in the factoring of the given expressions. Common factors are used once only and the one with the highest power is used. 3 x 3 - 2 x 2 - x and x - 1 . The LCM is by multiplying all factors included in the factoring of the given expressions.
Step-by-step explanation:
To find the LCM of given expressions, we proceed as follows:
1) Express each of the expressions as the product of its factors including prime factors where applicable.
2) Find the product of each factor with the highest power which occurs in the given expressions.
3) This product is the LCM.

If f(x)=x²+3x-2
find f(-2)
Answer:
f(- 2) = - 4
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4
Value of f(-2) is -4
Given that;
f(x) = x²+3x-2
Find;
Value of f(-2)
Computation:
Given that;
f(x) = x²+3x-2
By putting x = -2
f(-2) = (-2)² + 3(-2) - 2
f(-2) = 4 - 6 - 2
f(-2) = 4 - 8
f(-2) = -4
So, -4 is the correct answer to the given equation.
