Answer:
That would be (2,3)
Step-by-step explanation:
When we're moving left in the coordinate plane, we are subtracting the x-coordinate by how much distance we move.
In this case, 7-5=2, so the new x-coordinate is 2, but the y-coordinate doesn't change since we're going horizontally and not vertically.
Answer:
mass = density · volume
Step-by-step explanation:
To find the mass of a given volume, multiply your given volume by the <em>density</em>. Often, density is given in grams per cubic centimeter. 1 cubic centimeter is the same as 1 milliliter.
Answer:
m∠6 = 116°
Step-by-step explanation:
<u>first find x:</u>
7x - 17 = 2x + 78
subtract 2x from both sides: 5x - 17 = 78
add 17 to both sides: 5x = 95
divide by 5: x = 19
<u>plug x into 7x - 17</u>
7(19) - 17 = 116
∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°
Answer: ![A=2.5x^{2}](https://tex.z-dn.net/?f=A%3D2.5x%5E%7B2%7D)
Step-by-step explanation:
1. Let's write the following formula for calculate the area of a rectangle:
![A=yx](https://tex.z-dn.net/?f=A%3Dyx)
Where
is the lenght (the longer side) and
is the width (the shorter side).
2. You know that the length is 2.5 times as long as the other side, which indicates a multiplication. Then:
![y=2.5x](https://tex.z-dn.net/?f=y%3D2.5x)
3. So, you must substitute
into the equation for calculate the area of the rectangle and then you must simplify.
4. Then, you obtain the following expression:
![A=(2.5x)(x)\\A=2.5x^{2}](https://tex.z-dn.net/?f=A%3D%282.5x%29%28x%29%5C%5CA%3D2.5x%5E%7B2%7D)
