Question is using standard formula ax+by=c to find the slope by converting into slope intercept form y=mx+b
so we also need to convert ax+by=c into y=mx+b as shown below:



divide both sides by

Now compare it with y=mx+b, we get

So using values of a and b, we can find the slope
compare given equation -5x+2y=15 with ax+by=c, we get:
a=-5, b=2
Now plug both into above formula



Now matching these details with given choices we find that THIRD choice is the final answer.
The rule is -3, then +2
24-3 = 21
21 + 2 = 23
23-3= 20
20+2= 22
22-3= 19
19+2 = 21
21-3= 18
18+2 = 20
Answer:
act as if the ratio is a fraction 4:3 would be 4/3..
Step-by-step explanation:
Find out how much you need for one person then multiply by 18 is one way you could do this..
4 divided by 24 = 0.166666666666667 x 18 = 3 litres of lemon-lime soda.
2 divided by 24 = 0.083333333333333 x 18 = 1.5 pints of servet
6 divided by 24 = 0.25 x 18 = 4.5 cups of ice.
Hope this helps!
Your teacher may have wanted you to (some how) use your 6x tables to work this out?!
Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>

</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>

</h3><h3 /><h3>

</h3>
But
<h3>

</h3>
So we have

<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>

</h3>
<u>Using the rules of logarithms</u>
That's
<h3>

</h3>
Rewrite the expression
That's
<h3>

</h3><h3 /><h3>

</h3><h3>

</h3><h3>

</h3><h3 /><h3>

</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>
Hope this helps you
