Answer:
y=-3x+4
Step-by-step explanation:
im assuming that you need the equation of the table
to find slope, y2-y1/x2-x1 10-4/-2-0
6/-2=-3 slope=-3
y=mx+b just sub in the numbers from a point in the table
10=-3(-2)+b
10=6+b
b=4
y=-3x+b
Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
![32=k\times 20\\k=\dfrac{32}{20}=1.6\\\\k=1.6](https://tex.z-dn.net/?f=32%3Dk%5Ctimes%2020%5C%5Ck%3D%5Cdfrac%7B32%7D%7B20%7D%3D1.6%5C%5C%5C%5Ck%3D1.6)
Now when k =1.6 , y = 40 then x will be
![40=1.6\times x\\\\x=\dfrac{40}{1.6}=25\\\\x=25](https://tex.z-dn.net/?f=40%3D1.6%5Ctimes%20x%5C%5C%5C%5Cx%3D%5Cdfrac%7B40%7D%7B1.6%7D%3D25%5C%5C%5C%5Cx%3D25)
Therefore the value of x is 25 when y =40.
Answer: 6.71
=======================================
Work Shown:
The longest horizontal portion of length 6 breaks up into two equal pieces of length 3 each. Focus on the smaller right triangle on the right hand side. This right triangle has legs of 3 and 6. The hypotenuse is x.
Use the pythagorean theorem with a = 3, b = 6, c = x to find the value of x
a^2 + b^2 = c^2
3^2 + 6^2 = x^2
9 + 36 = x^2
45 = x^2
x^2 = 45
x = sqrt(45)
x = 6.7082039
x = 6.71

Answer:
d) 12(100) + 12(80) + 12(5)
Step-by-step explanation:
According to the distributive property, if a,b, c, and d are real numbers, then
a(b+c+d)=ab+ac+ad
We want to find the product 12(185).
We can expand 185 as 100+80+5
Our product then becomes;
![12(185)=12(100+80+5)](https://tex.z-dn.net/?f=12%28185%29%3D12%28100%2B80%2B5%29)
We expand using the distributive property to get;
![12(185)=12(100)+12(80)+12(5)](https://tex.z-dn.net/?f=12%28185%29%3D12%28100%29%2B12%2880%29%2B12%285%29)
The correct choice is D
