Answer:
it must be y=-5x+21
Step-by-step explanation:
lets type the equation in front of us and make it simple so we can deal with it
y-1=-5(x-4)
first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this
y-1=-5x+20 -5*x=-5,, -5*-4=20 (note: when you multiply negative with
negative result is positive)
then add each side by 1 so it will be
y=-5x+21
A student earned a grade of 80% on a math test. He answered 20 of the questions correctly. How many problems were on the test?
Answer: 25
Step-by-step explanation:
Given
The student earned 80% on a math test
The student answered 20 questions
Suppose x is the total no of questions
So, we can write
[tex]\Rightarrow \dfrac{20}{x}\times 100=80\%\\\Rightarrow \dfrac{20}{x}=0.8\\\\\Rightarrow \dfrac{20}{0.8}=x\\\\\Rightarrow x=25[/tex]
So, there are 25 questions in total

What is the value of b and the value of c? Picture of triangle down below.
b=
c=
Answer:
b = 73
c = 34
Step-by-step explanation:
<T and <R are equal because they are opposite equal sides.
So b = 73°
Every triangle has 180 degrees
b + c + 73 = 180
73 + c + 73 = 180
146 + c = 180
c = 180 - 146
c = 34

The number line which represents the solutions that is n > -3 is number line 1.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Any real number can be represented in two dimensions using a number line. Any number on the number line with a solid circle next to it refers to include that number followed by the rest of the values, and any number with a hollow circle refers to exclude that value from the list before the rest of the values.
The solutions represented by number line 1 are those where: n > -3.
Using special techniques, number lines are used to represent real numbers. It was Illustrated in number line 1.

What is m CD ?
Plzz help
Given:
Arc(AB) = 78 degrees
Measure of angle CMD = 106 degrees
To find:
The measure of arc CD.
Solution:
Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.
Using secant intersection theorem, we get
[tex]m\angle CMD=\dfrac{1}{2}(Arc(AB)+Arc(CD))[/tex]
[tex]106^\circ=\dfrac{1}{2}(78^\circ+Arc(CD))[/tex]
Multiply both sides by 2.
[tex]212^\circ=78^\circ+Arc(CD)[/tex]
[tex]212^\circ-78^\circ=Arc(CD)[/tex]
[tex]134^\circ=Arc(CD)[/tex]
Therefore, the measure of arc CD is 134 degrees and the correct option is C.

"A freely falling object experiences gravity. The value of gravity is 9.8 m/s2 or 980 cm/s2. The equation that describes the distance an object falls from rest under the influence of gravity is?"
Answer:
S =4.9t²
Step-by-step explanation:
Using the equation of motion
S =ut+1/2gt²
u is the initial speed = 0m/s
t is the time
g I the acceleration due to gravity = 9.8m/s²
S is the distance of the object
Substitute
S = 0(t)+1/2 (9.8)t²
S = 0+4.9t²
S = 4.9t²
Hence thee equation that describes the distance an object falls from rest under the influence of gravity is S = 4.9t²

in isosceles trapezoid EFGH, FG parallel EH, FG=10, GH=12, and ∠E=60. Find the area of EFGH.
Answer:
22√3 units squared
Step-by-step explanation:
1) Draw the trapezoid
2) Notice you have to find the height to find the area of the trapezoid
3) Notice it is a 30 60 90 triangle when you draw the line to find the height
4) Solve for the 30 60 90 triangle and you get the height to be 2√3
5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)
6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)
7) Keep aside the 1/2 for now
8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)
9) Simplify further 44√3
10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3
11) Simplify to get 22√3
12) 22√3 is the area of the trapezoid
13) 22√3 units squared is the final answer
I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.
If you want to know how I solved the 30 60 90 triangle please let me know.

The question says “the system below has been solved by graphing. How many solutions does it have?”
Answer:
Infinitely many solutions
Step-by-step explanation:
3x+y=1
15x+5y=5
Step: Solve3x+y=1 for y:
3x + y +−3 x = 1 + −3x (Add -3x to both sides)
y=−3x+1
Step: Substitute−3x+1 for y in 15x+5y=5:
15x+5y=5
15x+5(−3x+1)=5
5=5(Simplify both sides of the equation)
5+−5=5+−5(Add -5 to both sides)
0=0
so there are infinite solutions
