The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 is graphed below. On a coordinate plane, 2 lines intersect at (0, negative 1). What is the solution to the system of equations? (0, –1) (–1, 0) (0, 1) (1, 0)
Answer:
0, -1
Step-by-step explanation:
trust me I just took the exam on edge 2020
The solution to the given system of equations will be (0, -1). which is the correct option (B).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.
y = 2x - 1 ....(i)
y = -4x - 1 ....(ii)
Substitute the value of equation (i) in equation (ii) and solve for variable x :
2x - 1 = -4x - 1
Rearrange the terms of variable "x" and combine them,
2x + 4x = -1 + 1
6x = 0
x = 0
Substitute the value of x = 0 in equation (ii) and solve for variable y :
y = -4(0) - 1
y = -1
Therefore, the solution to the given system of equations will be (0, -1).

1/2x+5=10 whats the value of the variable
Answer:
1/2x+5=10
subtracting 5 from both sides 1/2x+5-5=10-5
1/2x=5
divide both sides by 1/2
1/2x÷1/2=5÷1/2

Raju took 5/6 h to complete his mathematics homework. He took 1/5 h less to complete his english homework. how many hours did raju take to complete his english homework? what was the total time spent by raju on his homework?
Answer:
English homework = 19/30h or 38 minutes
Total time spent = 22/15h or 88 minutes
Step-by-step explanation:
Mathematics homework = 5/6h
= 5/6 × 60
= 300/6
= 50 minutes
He took 1/5 h less to complete his english homework.
English = 5/6h - 1/5h
= 25h-6h/30
= 19/30h
= 19/30 × 60
= 1,140/30
= 38 minutes
English homework = 19/30h or 38 minutes
Total time spent on his homework = mathematics homework + English homework
= 5/6h + 19/30h
= 25h+19h/30
= 44/30h
= 22/15h
= 22/15 × 60
= 1,320 / 15
= 88 minutes
Julie works at a pizza place in Phoenix. She receives a 15% discount on any pizza that she buys. If a large pizza costs $14.00, what is the amount of Julie’s discount? What is the final cost of her pizza?
Answer:
The final cost of her pizza is $11.90
Step-by-step explanation:
First we need to convert 15% into a decimal, which is 0.15.
Now we multiply $14 and 0.15.
$14 × 0.15 = $2.10.
Now we subtract $2.10 from $14.00.
$14.00 - $2.10 = $11.90

Find the exact length of the third side.
Answer:
[tex]24x^{2} +7x^{2} =[/tex]
step-by-step explanation:
You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
Answer:
this is a right angle triangle.
which means that we can use hypotenuse theorem to solve it.
the hypotenuse theorem:-
a^2 +b^2 =c^2
where a and b are the sides opposite to the hypotenuse.
[(the longest side) the longest side of the triangle is always opposite to the right angle]
so...
a = 24
b = 7
a^2 + b^2 = c^2
24^2 + 7^2 = c^2
576 + 49 = c^2
625 = c^2
don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.
√625 = c
25 = c
thus the length of the third side is 25.

Step-by-step explanation:
Solve for y.
3x + 4y = z
-----------------
Answer:
y= z-3x/4
Step-by-step explanation:
4y=z-3x
y=z-3x/4
Answer:
[tex]y=\frac{z-3x}{4}[/tex]
Step-by-step explanation:
[tex]3x+4y=z[/tex]
Subtract 3x from both sides:-
[tex]3x+4y-3x=z-3x[/tex]
[tex]4y=z-3x[/tex]
Divide both sides by 4:-
[tex]\frac{4y}{4}=\frac{z}{4}-\frac{3x}{4}[/tex]
[tex]y=\frac{z-3x}{4}[/tex]
