You could also use a ruler or some other measuring device for (2). You can also draw a picture of a circle with the denominator as the slices, and the numerator as the shaded areas, then compare both fractions together for (3).
Here, = x(-y + z)
Just substitute the values,
= 3( -3 + 1)
= 3( - 2)
= -6
In short, Your Answer would be -6
Hope this helps!
The area would be 63.The steps to how I got that anwser:
1.] Write your formula
A=bh
----
2
2.]Begin by plugging in your measurements
A=7.5 times 16.8
-------------------
2
3.]Multiply the top two numbers together
A=126
-----
2
4.]Divide to get your final anwser
A=63
If the length is twice the width, then we could write
and
. For perimeter, there are two length measures and two width measures.
![p = 2l + 2w](https://tex.z-dn.net/?f=p%20%3D%202l%20%2B%202w)
This can be converted into
![2(2w) + 2(w) = p](https://tex.z-dn.net/?f=2%282w%29%20%2B%202%28w%29%20%3D%20p)
Hope I answered your question.
Answer:
<u>y = -3x + 8</u>
Step-by-step explanation:
<u>Given :-</u>
Point on line = (5, -7)
Slope (m) = -3
<u>To find :-</u>
Equation of line
<u>Solving :-</u>
Using point-slope form of equation,
y - y₁ = m(x - x₁)
y + 7 = -3(x - 5)
y + 7 = -3x + 15
<u>Solution :-</u>
<u>y = -3x + 8</u>
