Consider segment CD with coordinates C(7, -1) and D(-1, -6). Give the x coordinate of the midpoint of the segment?
===========================================================
Explanation:
The x coordinate of point C is x = 7
The x coordinate of point D is x = -1
Add up these x coordinates to get 7+(-1) = 6
Then cut that result in half: 6/2 = 3
The x coordinate of the midpoint is 3
The y coordinate of the midpoint is found in a similar fashion. You should find the midpoint is located at (3, -3.5) which is the same as saying (3, -7/2) since -7/2 = -3.5

i need to find the slopes from two points!show work.i don’t know how to do this
Answer:
4
Step-by-step explanation:
Ok.....Since I can't graph it, we can make a table
x y
3 9
1 1
From 9 to 1, you subtract 8 (this is for the y section)
From 3 to 1, you subtract 2 (this is for the x section)
Now all you have to do is divide the y with the x
y/x = 8/2 = 4
And 4 will be your slope for these two points.
Hope this helped!

The graph shows the motion of a car driving on a highway.
Enter a value to complete the statement.
Answer:
Car A's speed is 75 miles per hour
Step-by-step explanation:
As the distance-time graph represents the straight line. Thus, the slope of any line would remain constant along the line.
We also know that in a distance-time graph, the slope of the line would be equal to the speed of the object.
Taking two points from the graph
(0, 25)(1, 100)Determining the slope
Slope = [y₂-y₁] / [x₂-x₁]
= [100 - 25] / [1 - 0]
= 75 / 1
= 75 miles per hour
Therefore, Car A's speed is 75 miles per hour

Answer:
y = 42°
Step-by-step explanation:
The third vertex in the triangle with y is adjacent to a right angle, thus is right.
The sum of the 3 angles in a triangle = 180°, then
y = 180° - (90 + 48)° = 180° - 138° = 42°
Are the graph of 4x-3y=9 and y=3/4x+7 parallel, perpendicular, or neither? Explain.
Answer:
Neither
Step-by-step explanation:
In this question, we have to verify if the equations are parallel, perpendicular, or neither to each other.
Turn the first equation into slope-intercept form so we can get a better understanding:
4x - 3y = 9
Subtract 4x from both sides.
-3y = -4x + 9
Divide both sides by -3.
y = 4/3x - 3
Now lets compare both lines:
y = 4/3x - 3
y = 3/4x + 7
Since the slopes have to be the same in order for the lines to be parallel, we can see that the lines are NOT parallel.
We also know that in order for the lines to be perpendicular, one has to be positive and the other has to be negative. In this case, they both are positive. This means that the lines are NOT perpendicular.
This means that our answer would be neither.

Solve x2 + 6x = -6. If exact roots cannot be found, state the consecutive
integers between which the roots are located.
x²+6x=-6 ‖+6
x²+6x+6=0
x1=-(6/2)+√((6/2)²-6)= -3+√(3) or ≈ -1.267
x2=-(6/2)+√((6/2)²-6)= -3-√(3) or ≈ -4.732
The roots of the quadratic equation, x² + 6x = - 6 are between - 2 and - 1,
and 1 and 2.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, x² + 6x = - 6.
We know in ax² + bx + c = 0, x = ± √(b² - ac)/2a.
∴ x² + 6x + 6 = 0.
x = ± √(36 - 24)/2×1.
x = ± √(12)/2.
x = ± (2√3)/2.
x = ± √3.
We know √3 is between 1 and 2 and - √3 is between - 2 and - 1.

Answer:
Sue takes 3.3 hours to kayak 11 miles & marty takes 3.5 hours on her horse
Step-by-step explanation:
Sue's kayaking path is the hypotenuse of a right triangle.
so we use a squared + b squared = c squared
10.5^2+3.2^2=c^2
110.25+10.24=c^2
120.49=c^2
10.9768=c
and then because it said to round to the nearest tenth that would be 11.0 miles.
She's going at an average speed of 3.3 mph
that means it takes her about .3 hours to do 1 mile
so it would take her 3.3 hours to go 11 miles
marty is going at an average speed of 7 mph
so she takes 0.14 hours to go 1 mile
0.14 x 25 = 2.5

3:4 3:1 2:3 1:3 9:7 6:7A pair of shoes that normally cost $30 have their price reduced by 25%. What is the sale price of the shoes?
Answer:$22.50
Step-by-step explanation: you save $7.50
Sale price of shoes = $22.5
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, we have to divide the given number by the whole number and multiply by 100.
Given,
Cost of shoes = $30
Discount on shoes = 25%
Discount = (25/100) × 30
Discount = 750/100
Discount = $7.5
Sale price = Cost - discount
Sale price = $30 - $7.5
Sale price = $22.5
Hence, $22.5 is the sale price of shoes.
