What is the solution of the system of linear equations graphed below?
Answer: (1.125,-0.25)
Step-by-step explanation: The point that is the same for both equations is the point where they intersect. It appears from the graph to be around (1,0). We should confirm this by deriving the equation for each line and then solving them. Use the standard format: y = mx+b, where m is the slope and b the y-intercept.
I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x). The y intercept is 2 (b). This equation would be y = mx+b, or y = -2x + 2.
The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1
Set these two equations equal to each other and solve for x.
-2x+2=(2/3)x-1
x = 1.125
Use that value of x to solve for y: y = -0.25
The point of intersection is therefore (1.125, -0.25)
Under her cell phone plan, Aubree pays a flat cost of $50.50 per month and $4 per gigabyte. She wants to keep her bill at $56.10 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Aubree can use while staying within her budget.
Equation:
Answer: g =
Answer:
50.50 + 4g ≤ 56.10
Step-by-step explanation:
The variable is g, the amount of gigabytes she uses and each gigabyte costs $4 therefore the equation must be set as the flat fee, $50.50 plus 4g since it costs $4 per gigabyte to be less or equal to $56.10 since Aubree wants to stay below $56.10.
What is the surface area of a cylinder with base radius 4 and height 5?

If the area of a square with side x is 9,
what is the area of a square of side 4x
Answer:
144
Step by step explanation ;
Area of square is S×S
side X×X=9
X equals 3
4×3=12
12×12=144
The area of a square of side 4x will be 36 square units.
What is the area of the square?A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.
Also, each vertex of the square has an angle equal to 90 degrees.
The area of the figure is the product of the length of the side.
Area of square = Side × Side
The area of a square with side x is 9. Then the area will be
Area = 4x
Area = 9 × 4
Area = 36
The area of a square of side 4x will be 36 square units.

Please help
Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36

Answer:
The square root of 2 is between 1 and 2, so radical 2 is about 1.4.
Step-by-step explanation:
You can plot a 1 on the very left and a 2 on the very right of the number line.
Since there is no formal square root of 2, you have to estimate.
It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.
It also has to be greater than 1 because 1 * 1 = 1 and that's too low.
I would estimate it to be right before the middle line.

Step-by-step explanation:
We can set up this problem by making an equation.
(2900-1200-200-5%)(x)=5000
(1500-5%)(x)=5000
(1425)(x)=5000
5000 divided by 1425 equals 3.50...
My answer would be 3 1/2 months but I could be wrong.

Answer:
-17
Step-by-step explanation:
First, let's see what the value of w is, by solving -5w - 5 = 5.
-5w - 5 = 5 Add 5 on both sides.
-5w = 10 Divide -5 on both sides.
w = -2
Now, we know that w is equal to -2, let's plug it in to find the value.
9(-2) + 1 Distribute.
