Hey!
Adjacent angles are when two angles in a plane share a vertex and side but no common interior points.
I hope this helps;)
Direct variation
Explanation:
Given –2 + 4y + 2 = 8x.
To find the given expression –2 + 4y + 2 = 8x is direct variation or not.
If y varies directly as x, then y = kx.
If y varies inversely as x, then
⇒ –2 + 4y + 2 = 8x
Combine like terms together.
⇒ –2 + 2 + 4y = 8x
⇒ 4y = 8x
Divide both sides of the equation by 4, we get
⇒ y = 2x
Which is in the format of y = kx.
Thus y varies directly as x.
Hence, –2 + 4y + 2 = 8x is direct variation.
If the number of dogs seen by the veterinarian is 40 then the number of cats seen by him will be equal to 16.
The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.
As per the data given in the question,
The ratio of cats to dogs seen by veterinarian = 2:5
Number of dogs seen by veterinarian = 40
Let the number of cats seen by him be x.
Then, the ratios will be,
C : D
2 : 5
x : 40
Use cross-multiplication to find the number of cats,
5x = 2 × 40
x = (2 × 40)/5
x = 2 × 8
x = 16

Answer:
The Volume of 10 g of Gasoline is 14.286 ml approximately.
Step-by-step explanation:
Consider the provided information.
We need to find the Volume of 10 g of Gasoline.
Solve this with using the formula shown below:
Volume = mass/density
The density of gasoline is 0.7 g/ml.
Substitute the respective values in the above formula as shown:
Hence, the Volume of 10 g of Gasoline is 14.286 ml approximately.
Answer:
easy, if the intercepts or roots or zeros of the equation are r₁ and r₂ then 2 factors of the equatain are (x-r₁) and (x-r₂)
so
we see it intercepts the x axis at 1 and 6
r₁=1
r₂=6
therefore 2 roots are (x-1) and (x-6)
answer is 2nd option
