What is the solution to this set of equations?
2x+2y=6
x-y=3
Which answer is correct?
(0,-3)
(3,0)
(6,3)
(0,3)
Answer:
(3,0)
Step-by-step explanation:
2x + 2y = 6 divide thru by 2 and you get x + y = 3
Name x + y = 3 equation (1) and x - y = 3 equation (2)
Add equations (1) and (2)
(1) x+ y = 3
(2) x - y = 3
2x = 6
x = 3
Substitute x = 3 into equation (1). So, 3 + y = 3
y = 0

The total surface area of a cube is 600
in2. What is the length of each side of the
cube? It is in.
Answer:
10
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
600 / 6 = 100
10 x 10 = 100

Problem ID: PRABMTFA A solid with volume 12 cubic units is dilated by a scale factor of k. Find the volume of the image for each given value of k.
k=1/4
Answer:
Step-by-step explanation:
3/16
You can use the fact that you can think of the solid as made up of 12 cubes with side length of 1 unit.
The volume of the image of the dilated solid is for k = 1/4 is
3/16 cubic units
How can we interpret measurement of something?Remember that volume, area, length etc all are measured relatively.
If you are 1.7 meters tall, then you're height is measured relative to meters. This is called unit of the measurement. It means that if we collect 1 meter and 0.7 meters too,they together will be equally tall as you.
Similarly, if we say that a triangle has area of 40 square inches, then it means that its area is equal to 40 squares of 1 inch sides.
Using above understanding to find the volume of the dilated solidSince the original solid was of 12 cubic units. it means its volume was equal to the total volume of 12 cubes with 1 unit side length.
Now since the scale factor of the dilation is k, that means each of the cube got its side length multiplied by k
Now volume of 12 cubes with side length k units is given by
[tex]V = 12 \times k^3[/tex]
Since it is given that k = 1/4, we have:
[tex]V = 12 \times (\dfrac{1}{4})^3 = \dfrac{3}{16} \: \rm unit^3[/tex] now there are 3/16 cubes with 1 unit length.
Thus,
The volume of the image of the dilated solid is for k = 1/4 is
3/16 cubic units

Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
3.75=3.75/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10 to the power of 2 = 100
3.75/1×100/100=375/100
Find the Greatest Common Factor (GCF) of 375 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25,
375 ÷ 25
_______ = 15/4
100 ÷ 25
Simplify the improper fraction,

x2 = 16
3+xV7-13
7x = 14
Answer:
3+x sqrt 7 -13 is a radical equation.
The value of radical equation is,
⇒ 7√x = 14
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
All the equations are,
⇒ x +√5 = 12
⇒ x² = 16
⇒ 3 + x√7 = 13
⇒ 7√x = 14
Since, A radical equation is an equation with at least one variable put on a radical form.
In this question, there is only one kind of variable which is x.
Then, you need to find the equation where x is in the radical form.
Hence, The radical form can be expressed with square root symbol.
Therefore, The option with √x would be only,
⇒ 7√x = 14
Thus, The value of radical equation is,
⇒ 7√x = 14

Area of the Composite Figure:
in?
8 in
bi
16in
Answer:
86.14 in.²
Step-by-step explanation:
Area of the composite figure = area of semicircle + area of rectangle + area of triangle
= (½πr²) + (L*W) + (½bh)
Where,
r = ½*6 = 3 in.
L = 8 in.
W = 6 in.
b = 16 - 8 = 8 in.
h = 6 in.
Plug in the values and solve
Area of composite figure = (½*π*3²) + (8*6) + (½*8*6)
= 14.14 + 48 + 24
= 86.14 in.²

Given:
The center of the circle = (-1,0)
Point on the circle = (2,-4).
To find:
The equation of the circle.
Solution:
Distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between the center (-1,0) and the point on the circle (2,-4) is the radius of the circle.
[tex]r=\sqrt{(2-(-1))^2+(-4-0)^2}[/tex]
[tex]r=\sqrt{(2+1)^2+(-4)^2}[/tex]
[tex]r=\sqrt{(3)^2+(-4)^2}[/tex]
On further simplification, we get
[tex]r=\sqrt{9+16}[/tex]
[tex]r=\sqrt{25}[/tex]
[tex]r=5[/tex]
Now, the equation of the circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center and r is the radius of the circle.
The radius of the circle is 5 and the center is at (-1,0), so the equation of the circle is
[tex](x-(-1))^2+(y-0)^2=5^2[/tex]
[tex](x+1)^2+y^2=25[/tex]
Therefore, the first option is correct, i.e., [tex](x+1)^2+y^2=25[/tex].

2x - x + 7 = x + 3 + 4
Answer:0
Step-by-step explanation:
Simplifying
2x + -1x + 7 = x + 3 + 4
Reorder the terms:
7 + 2x + -1x = x + 3 + 4
Combine like terms: 2x + -1x = 1x
7 + 1x = x + 3 + 4
Reorder the terms:
7 + 1x = 3 + 4 + x
Combine like terms: 3 + 4 = 7
7 + 1x = 7 + x
Add '-7' to each side of the equation.
7 + -7 + 1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
0 + 1x = 7 + -7 + x
1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
1x = 0 + x
1x = x
Solving
1x = x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
1x + -1x = x + -1x
Combine like terms: 1x + -1x = 0
0 = x + -1x
Combine like terms: x + -1x = 0
0 = 0
Simplifying
0 = 0
The solution to this equation could not be determined.
