Describe the graph of the proportional relationship represented by the equation y = 7.5x.
Answers
The graph of the equation y = 7.5x shows the proportional relationship.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
y = 7.5x.
The graph of the equation y = 7.5x is shown below.
At x = 1, the value of y = 7.5,
At x = 2, the value of y = 7.5 x 2 = 15
At x = 3, the value of y = 7.5 x 3 = 22.5
And so on.
The value of y multiplied by 7.5 by increasing value of x by 1.
Thus, the graph of the equation y = 7.5x shows the proportional relationship.

Explain why dividing each side of \small 3x^2=6x by \small 3x is not a reliable way to solve the equation.
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]3x^2 = 6x[/tex]
Required
Why dividing by [tex]3x[/tex] is not reliable
The reason is that, the given expression is a quadratic equation and as such, it will most likely have two solutions.
So, when the expression is divided by [tex]3x[/tex], the solution will be [tex]x = 2[/tex], leaving out the other possible solution.
The right way is:
[tex]3x^2 = 6x[/tex]
Subtract 6x from both sides
[tex]3x^2 - 6x = 6x - 6x[/tex]
[tex]3x^2 - 6x = 0[/tex]
Factorize
[tex]3x(x - 2) = 0[/tex]
Split
[tex]3x = 0\ or\ x - 2 = 0[/tex]
Solve for x in both cases:
[tex]x = 0\ or\ x = 2[/tex]

What are permutation and combination?In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Dora has three candles, which will burn for 3, 4, and 5 hours,
The combination of the hours of burning,
3 + 4 = 7 hours
4 + 5 = 9 hours

Step-by-step explanation:

8x° + 140° = 180°
(Linear pair angles)
8x° = 180° - 140°
8x° = 40°
x ° = 40°/8
x° = 5°
x = 5
12.
2x° + 42° = 90°

2x° = 90° - 42°
2x° = 48°
x ° = 48°/2

Izzy is saving up for a road trip that is happening6 weeks from today. At this moment, Izzy has $90 in her savings account. She plans on saving $25 a week.
Answers
Answer:
$210
Step-by-step explanation:
Given data
time = 6 weeks
initial amount= $90
saving per week = $25
Hence the expression for the total savings after the 6 weeks is given as
y= mx+c
where
m= $25
x= 6 weeks
c= $90
substitute
y=25*6+90
y= 150+60
y= $210
Hence the total amount after 6 weeks is $210
