The expression equivalent to m<4 when the given image is examined is m<2 + m<3.
What are the angles equivalent to m<4?According to mathematical theory, an exterior angle is equal to the sum of the two interior opposite angles. An exterior angle is formed when a line extended from an adjacent side of a regular polygon. An interior angle is the angle that is formed inside the polygon.

Graph the image of the given triangle after a rotation of 180° about the origin
Answers
Answer:
The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)
Step-by-step explanation:
Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.
(x,y) → (-x,-y)
Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).
The transformation (x,y) → (-x,-y) gives ;
(-1,1) → (1,-1)
(-2,6) → (2,-6)
(-5,4) → (5,-4)
Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".

Rearrange the equation y+5=3/4(x-12) into slope-intercept form.
PLEASE show work for brainliest
Answers
y+5=3/4x-9— distributing the 3/4
y=3/4x - 14 — subtracting 5 from both sides
final answer is y=3/4x - 14 since slope intercept form is y=Mx+b
The equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).
What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
An equation is given which is :
y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12)
If we multiply by 4 on both sides , we get :
4y + 20 = 3x - 36
or
4y = 3x - 56 -- -- -- -- --- ---- ----- ----- --- --- --- Equation 1
We know that the slope intercept form of a line is given by :
y = mx + c
So , to change the above equation into slope intercept form we must divide equation 1 by 4. So , the rearranged equation will be :
4y / 4 = (3/4 x ) - (56 / 4)
y = [tex]\frac{3}{4}[/tex] x + (-14)
Therefore , the equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).

This is so hard and I don’t know why
Answers
Answer:
Hey girl! I got you.
Step-by-step explanation:
So! The angle x and z are congruent, meaning that they are equal, so you got that part correct. They are indeed 103. Next you need to find y, and in this case you need to do 180 - 103 because the line that holds both angle z and angle y is equal to 180.
180 - 103 = 77, you got that correct also!
You're on the right track, just explain in words how you know what each angle is equal to! Good luck! :)

Terry’s average driving speed for a 2 and a half hour trip was 58 mph. How far did Terry travel?
Answers
145 miles. lets see how i got this.
so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.
sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.
side-sidenote: i hope this answers your question and helps you in the future.
key: r= rate (mph or kph), d=distance, and t=time.
The length of the base of an isosceles triangle is x. The length of a leg is 5x – 3. The perimeter of the triangle is 60. Find x.
X
Answers
Answer: x = 6
Step-by-step explanation:
The perimeter of the isosceles triangle = 2 leg + base
Since the perimeter = 60
then 60 = 2(5x - 3) + x
60 = 10x - 6 + x
60 + 6 = 11x
6 = x
Step-by-step Explanation:
The legs are both the same so 2(5x - 3) accounts for both. Then add x and simplify.
10x - 6 + x
11x - 6
Set equal to 60
11x - 6 = 60
11x = 66
x = 6

a² - b² = (a - b)(a + b) , then

To solve for the slope, choose two pairs of coordinates and substitute their values into the slope formula.
Let (x1, y1) = (1, 5)
(x2, y2) = (2, 4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 5)/(2 - 1)
m = -1/1
m = - 1
Therefore, the slope, m = -1.
For the y-intercept, choose one of the given points, and use it along with the slope to solve for the y-intercept. Using point (2, 4) and the slope, m = -1, substitute their values into the slope-intercept form:
y = mx + b
4 = -1(2) + b
4 = -2 + b
Add 2 to both sides to solve for b:
4 + 2 = -2 + 2 + b
6 = b
Therefore, the linear equation is :
y = -x + 6

so here, one year's interest is
I = 300(.045) = 13.5
Divide 50 by 13.5 and get 3.7 years...thus
she will need four years to donate 50...
Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
given
Principal(P) = 300
Interest Rate(I.R) = 4.5%
Simple Interest(S.I) = 50
required
Time(T)
I.R = (S.I × 100)
(P ×T)
T × I.R = (S.I × 100) ×T
I.R (P × T) × I.R
T = (S.I × 100)
(P × I.R)
= (50 × 100)
