Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
<u>ANSWER:
</u>
Colby hit 8 home runs.
<u>SOLUTION:
</u>
It is given to us that Colby hit four more home runs that twice the number of home runs Dominic hit and together they hit ten home runs.
Let us denote the runs hit by Colby as ‘c’ and that hit by Dominic as ‘d’.
According to the given statement
d + c = 10 --eq1
and we also know that Colby hit four more home runs that twice the number of home runs Dominic hit. So we can write it in an equation as follows:
c = 2d + 4 -- eq2
Now from the eq1and eq2 we can solve to find out how many runs Colby hit Let's rewrite equation one as follows:
d = 10 - c -- eq3
Now substituting eq3 in eq2 we get the following:
c = 2(10 - c) + 4
We can rewrite the equation as:
c = 20 - 2c + 4
3c = 24
c = 8
Therefore Colby hit 8 home runs.
Answer:
<u>The third table is an arithmetic sequence </u>. Its difference is -1.4.
Step-by-step explanation:
In an arithmetic sequence the difference between one term and the next is a constant
8.7 - 1.4 = 7.3
7.3 - 1.4 = 5.9
5.9 - 1.4 = 4.5
4.5 - 1.4 = 3.1

Answer:
<h2>
x = 2</h2>
Step-by-step explanation:
(7x + 9)° is corresponding angle to (9x + 5)° angle
Therefore:
m║n ⇒ (7x + 9)° = (9x + 5)°
(7x)° + 9° = (9x)° + 5° {subtract (7x)° from both sides}
9° = (2x)° + 5° {subtract 5° from both sides}
4° = (2x)° {divide both sides by 2°}
x = 2
