What is the midpoint of AB ?
B
Answer:
hope it helps you........
Step-by-step explanation:
The midpoint formula is
[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]
Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.
The points are
(-5,-4)
(-3,3) So the midpoint is
[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]
Which gives us
[tex] - 4 \: and \: - 0.5[/tex]
So the midpoint is

Find the inverse of the following
F(x)=-3/4x+6
Answer:
[tex] {f}^{ - 1} (x)= - \frac{4}{3} x + 8[/tex]
Step-by-step explanation:
[tex]f(x) = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6[/tex]
[tex]x = - \frac{3}{4} y + 6[/tex]
[tex] - \frac{3}{4} y + 6 = x[/tex]
[tex] - 3y + 24 = 4x[/tex]
[tex] - 3y = 4x - 24[/tex]

b + 3/2b + b + 45 + 2b - 5 + 90 = 540
b + 1.5b + b + 45 + 2b - 5 + 90 = 540
5.5b + 130 = 540
5.5b = 540 - 130
5.5b = 410
b = 410/5.5
b = 74.5
Angles are
b = 74.5
1.5(74.5) = 111.75
74.5 + 45 = 119.5
2(74.5) - 5 = 144

Answer:
y = 3/4x + 19/2
Step-by-step explanation:
m = 3/4. point (-6,5)
Point slope form:
y-5=3/4(x- -6)
y -5 = 3/4x + 18/4. 18/4 = 9/2
Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?
Each group used 9 pictures, first divide total pictures by pictures per group to find total groups:
585 / 9 = 65 total groups.
Each group had 3 students.
Multiply total groups by students per group:
65 x 3 = 195 total students
Answer: 195 students.
What is the common difference of the following sequence? 27, 11, -5, -21, -37, . . .
Answer:
Find the common difference and the next term of the following sequence:
3, 11, 19, 27, 35...
Step 1. To find the common difference, subtract any consecutive pair of terms.
11 - 3 = 8
19 - 11 = 8
27 - 19 = 8
35 - 27 = 8
The difference is always 8, so d = 8.
Step 2. Use the common difference to find the next term.
Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.
Step-by-step explanation:
mark me brainliest plz
Answer:
[tex]d = a_{2} - a _{1}[/tex]
d is the common difference
a1 is the first term, a1 = 27
a2 is the second term, a2 = 11
substitute:

Answer:
the first one: The coordinates of A' are (-2, 3)
and the last one: The coordinates of B' are (-2, 0) and the coordinates of C' are (2, -1).
Step-by-step explanation:
when you rotate a triangle counterclockwise by 90° you swap the numbers of the x and y coordinates.
like how the coordinates of B' were (0, 2) and became (-2,0) once the triangle was rotated.

write an equation that contains points (0, 4) and is perpendicular to x-3y=-12
Answer:
y= -3x+4
Step-by-step explanation:
x+12=3y
(x+12)/3 = y
slope =
[tex] \frac{1}{3} [/tex]
the new slope = -3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b
4 = -3×(0) + b
b= 4
so y= -3x+4
Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?
We have an algebra problem.
We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.
The information given is:
The pickup can travel 45 miles on 3 gallons of gas.
To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)
This is:
r = (45 miles)/(3 gallons) = 15 miles/gallon.
Now that we know this, the number of gallons needed to travel 30 miles is given by:
N = (30 miles)/(15 miles/gallon) = 2 gallons.
N = 2 gallons.
The pickup needs 2 gallons to travel 30 miles.
