For question 4 I know it has the answer already but I just need the steps by step for it its the midpoint formula. If you know can you help me out
Answers
Answer:
M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2) = (1/2, 1)
Step-by-step explanation:
The midpoint (M) of segment AB is ...
M = (A +B)/2
That is, for coordinates A = (ax, ay) and B = (bx, by), the midpoint is ...
M = ((ax, ay) +(bx, by))/2
M = ((ax+bx)/2, (ay+by)/2) . . . . midpoint formula
__
For A(-4, -1) and B(5, 3), M will be ...
M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2)
M = (1/2, 1) . . . . as you know

Solve for x -9<4x+3<27 enter your answer as one inequality in the box
Answers
If a< c< b then a<c and c<b
Separate the equation into 2 separate ones and solve them:
X-9 < 4x +3
Subtract 3 from both sides:
X-12 < 4x
Subtract x from both sides:
-12< 3x
Divide both sides by 3:
X > -4
4x+3 < 27
Subtract 3 from both sides
4x < 24
Divide both sides by 4
X <6
Combine to get one inequality:
-4<x<6
The Solution of the inequality [tex]x-9 < 4x+3 < 27[/tex] in the form of one inequality is : [tex]-4 < x < 6[/tex]
We have the following inequality with us -> [tex]x - 9 < 4x+3 < 27[/tex]
We have to solve this inequality and the answer should be expressed as one - single inequality.
What is an inequality? Does [tex]a < b < c[/tex] means [tex]a < b[/tex] and [tex]b < c[/tex] ?Inequality in mathematics is a relation that helps us to compare two or more mathematical expressions. The expressions can be related to each other using the following operators > (greater then), < (less then), ≥ (greater then or equal to), ≤ (less then or equal to). Yes, the inequality [tex]a < b < c[/tex] signifies (or means) that [tex]a < b[/tex] and [tex]b < c[/tex].
[tex]a < b < c \; \;\;means\; \;\;a < b\; \;and\; \;b < c[/tex]
Using the above rule, we can also solve the inequality given to us :[tex]x-9 < 4x +3 < 27[/tex] by separating it into two different inequalities as follows-
[tex]x-9 < 4x+3[/tex] (Inequality 1)
and
[tex]4x + 3 < 27[/tex] (Inequality 2)
Solving the Inequality - 1 :
[tex]x-9 < 4x+3[/tex]
Subtracting [tex]x[/tex] on both sides, we get -
[tex]x-9-x < 4x-x+3\\\\-9 < 3x+3[/tex]
Adding [tex]-3[/tex] on both sides, we get -
[tex]-3-9 < 3x+3-3\\-12 < 3x[/tex]
Dividing both sides by [tex]3[/tex]. we get -
[tex]\frac{-12}{3} < \frac{3x}{3}[/tex]
[tex]x > -4[/tex]
Solving the Inequality - 2 :
[tex]4x+3 < 27[/tex]
Subtracting [tex]3[/tex] from both sides, we get -
[tex]4x+3-3 < 27-3\\4x < 24[/tex]
Dividing both sides by [tex]4\\[/tex]. we get -
[tex]\frac{4x}{4} < \frac{24}{4}[/tex]
[tex]x < 6[/tex]
Now, on solving the above two inequalities, we got the following result -
[tex]x > -4[/tex] and [tex]x < 6[/tex]. Combining both to one inequality, we get -
[tex]-4 < x < 6[/tex]
Hence, the solution for the inequality - [tex]x-9 < 4x+3 < 27[/tex] can be written in one-inequality as -
[tex]-4 < x < 6[/tex]

To Find:The value of x.
Angle Sum Property:The sum of all the Interior Angles of a triangle is 180°.
Solution:x + 2x + 45° = 180°
or, 3x = 180° - 45°
or, 3x = 135°
or, x = 135/3 = 45°
Answer:The value of x is 45°.
Answer:
x = 45

Trent is simplifying the expression 47 × 13. He claims he can solve the problem by multiplying 47 × 10 and adding it to the product of 47 × 3. Select the answer that best explains whether or not his strategy is correct. Trent is incorrect, because one group of 13 is not the same as one group of 10 and one group of 3. Trent is incorrect, because he would need to add the 3 to 47 before multiplying it by 10. Trent is incorrect, because he must first round 47 to a number that is easier to multiply. Trent is correct, because one group of 13 is the same as one group of 10 and one group of 3.

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
(-9,7), (6,2)
Answers
Answer:
Point-slope form: [tex]y-2=-\frac{1}{3} (x-6)[/tex]
Slope-intercept form: [tex]y=-\frac{1}{3}x+4[/tex]
Step-by-step explanation:
So, first, we need point-slope form.
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex]
In this form, m is your slope and [tex]x_1, y_1[/tex] is your point.
We have two points, so let's find the slope.
Slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
The y_2 and y_1 points can be interchanged, but order can't be changed (a y_2 can't go with an x_2).
For this problem, (-9,7) is going to be the x_2, y_2 pair.
[tex]x_2[/tex] = -9
[tex]y_2[/tex] = 7
[tex]x_1[/tex] = 6
[tex]y_1[/tex] = 2
Let's put the values into the formula.
[tex]\frac{7-2}{-9-6}[/tex] = [tex]\frac{5}{-15}[/tex] = [tex]-\frac{1}{3}[/tex]
The slope is 1/3. Going back to point-slope form, let's put the slope in.
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-y_1=-\frac{1}{3} (x-x_1)[/tex]
Now, lets put our x_1, y_1 point in.
[tex]y-2=-\frac{1}{3} (x-6)[/tex]
This is our point-slope form.
Now, to convert this to slope-intercept form, multiply everything out.
[tex]y-2=-\frac{1}{3}x+2[/tex]
Add two.
[tex]y=-\frac{1}{3}x+4[/tex]
This is our slope-intercept form.

195 = 75 + (10 + 8)w
195 - 75 = (10 + 8)w
120 = (10 + 8)w
120 = (2)w
120 ÷ 2 = w
60 = w
