In an arithmetic equation, there is no variable in the 'meat' of the equation(example: 5-5=0). In an algebraic equation, there is a variable in the meat of the equation(example: 5-x=0).

Answer:
- Is y = 4x - 7 a linear function?
- Is y = 6x² - 1 a linear function?
- Is y =
+ 10 a linear function?
Step-by-step explanation:
- Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
- No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
- No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.
For the graphs -
- The first one represents the linear function [y = 4x - 7]
- The second one (that looks like an L) represents the last not linear function [y = + 10]
- The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

Answer:
Step-by-step explanation:
Let s represent the son's age now. Then s+32 is the father's age. In 4 years, we have ...
5(s+4) = (s+32)+4
5s +20 = s +36 . . . . . eliminate parentheses
4s = 16 . . . . . . . . . . . . subtract s+20
s = 4
The son is now 4 years old; the father, 36.
_____
<em>Alternate solution</em>
In 4 years, the ratio of ages is ...
father : son = 5 : 1
The difference of their ages at that time is 5-1 = 4 "ratio units". Since the difference in ages is 32 years, each ratio unit must stand for 32/4 = 8 years. That is, the future age ratio is ...
father : son = 40 : 8
So, now (4 years earlier), the ages must be ...
father: 36; son: 4.
Answer:
the number of blonde hair is 10
Step-by-step explanation:
The computation of the number of blonde hair is shown below;
Given that
Ratio of blonde to brunetees is 2:3
And, there is total of 25 students
So, the number of blonde hair is
= 25 × 2 ÷ (2 + 3)
= 25 × 2 ÷ 5
= 10
Hence, the number of blonde hair is 10
Answer:
1/3
Step-by-step explanation:
To convert a decimal to percent, we multiply the decimal by 100. To convert a fraction to decimal, we divide the numerator by the denominator using long division and to convert a fraction to percent, we convert the fraction to decimal and the decimal to percent.
