y=-x+2
y=3x-1
Answer:
x = 3/4
y = 5/4
Step-by-step explanation:
Step:
Substitute−x+2 for y in y=3x−1:
y=3x−1
−x+2=3x−1
−x+2+−3x=3x−1+−3x(Add -3x to both sides)
−4x+2=−1
−4x+2+−2=−1+−2 (Add -2 to both sides)
-4x = -3
x=3/4
Step: Substitute x into the original equation
y=-3/4 + 2
y=5/4
Hope this helps!!

Answer:
-10
Step-by-step explanation:
the upper right is the same (105°), therefore the left 75°
now you have 180 = 75 + x + 115
therefore: -10
Maria has two options for buying a new computer. She can pay $750 right now, or she can pay $24.99 each month for 3 years. How much more will Maria pay if she makes payments for 3 years?
Answer:
$149.64
Step-by-step explanation:
Recall that there are 12 months in a year. Thus, 3 years would be 36 months.
$24.99 times 36 months comes to $899.64. To determine how much more Maria will pay by making monthly payments is $899.64 less $750, or $149.64.

Hi! i'm showing this to my sister and she wants to know, At a yard sale, Jennifer sold 2 tricycles for $22.50 each, 3 old video games for $2.75 each, a video for $5.00, and a dictionary for 75 cents. How much money did she make?
Jennifer made $59.
$22.50 times 2 is $45 and $2.75 times 3 is $8.25, the sum of these numbers is $53.25.
$5 plus $0.75 is $5.75, and the sum of $5.75 plus $53.25 is exactly 59 dollars.
If this is incorrect, please, don't refrain to tell me.

Which equation represents a nonlinear function? y=−85x+19.4 y = − − 8 5 x + 19.4 y=−12x2−7 y = − − 1 2 x 2 − − 7 y=x4+x y = x 4 + x y=32−4
Answer:
The answer is below.
Step-by-step explanation:
The options are not clear. I would solve a similar question.
A linear function is a function in the form:
y = mx + b; where y and x are variables, m is the slope and b is the y intercept.
From the options:
a) x(y - 5) = 2
xy - 5x = 2. Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.
b) y - 2(x + 9) = 0
y - 2x - 18 = 0
y = 2x + 18. The equation is in the form of y = mx + b, hence it is a linear function.
c) 3y + 6(2 - x) = 5
3y + 12 - 6x = 5
3y = 6x - 7. The equation is in the form of y = mx + b, hence it is a linear function.
d) 2(y + x) = 0
2y + 2x = 0
2y = -2x. The equation is in the form of y = mx + b, hence it is a linear function.

A) -10
B)10
C)-17
D)17
Answer:
sorry but the epuation is in,but I will try
Step-by-step explanation:
0 = -3×2+17x-10
0= -6+17x-10
0+6+10=17x
16=17x
x=17/16

Which measurements is equivalent to 4,000 centimeters? (100 centimeters = 1 meter)
Answer:
400 meters = 4000 centimeters
Step-by-step explanation:
Sorry if this didn't help
The solution is , 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.
Here,
we know,
100 centimeters = 1 meter
Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.
So, to convert 40 meters to centimeters, we can multiply 40 by 100:
40 meters = 40 x 100
= 4,000 centimeters
Therefore, 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

How much air can the basketball
hold? With a radius of 3 inches. Round to the nearest hundredth.
Answer:
113.10 if you use the pi button
113.04 if you use 3.14
Step-by-step explanation:
We want to find the volume
V = 4/3 pi r^3
The radius is 3
V = 4/3 pi (3)^3
Using the pi button for pi
V = 113.09734
Rounding to the nearest hundredth
V = 113.10
If you use 3.14 for pi
V = 113.04
Mr. Ramirez built a wooden storage shed for his tools. The dimensions of the shed are shown below. What is the volume of the storage shed to the nearest cubic foot?
Answer:
[tex]Volume = 24\ ft^3[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]Length = 170cm\\ Width = 100cm\\ Height = 40cm[/tex]
Required
Determine the volume
This is calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 170cm * 100cm * 40cm[/tex]
[tex]Volume = 680000cm^3[/tex]
Convert to cubic foot [Divide by 28317 ]
[tex]Volume = \frac{680000\ ft/^3}{28317}[/tex]
[tex]Volume = 24.0138432744\ ft^3[/tex]
[tex]Volume = 24\ ft^3[/tex] --- approximated
