Answer: 2 and
Step-by-step explanation: equation 2:
3(3x+4)-5=9x-2
9x+12-5=9x-2
9x+7=9x+-2
Subtract both sides by 9x
7=-2
This Is not true therefore there is no solution
equation 3:
3(3x+4)-5=-3x+4
9x+12-5=-3x+4
9x+7=-3x+4
12x=-3
divide both parts by -3
x=-4

Using linear interpolation on the interval [15,23] that would be
9.5 + (22-15)/(23-15) * (11.9-9.5) = 11.6
That is, since 22 is 7/8 of the way from 15 to 23, he should produce a value 7/8 of the way from 9.5 to 11.9
The correct answer is 11.9

Help me find the answer to this please!!
Answers
Explanation
When you have a graph, you can find the slope or coefficient next to x, by finding rise over run on the graph or using slope formula.
On the graph, from 0, 0, we go up or rise +6 and go right or run +1. Slope is 6/1 or 6.
Or, you have (0, 0) and (1, 6) as two definite points. Using slope formula
y2 - y1 over x2 - x1
6 - 0 over 1 - 0 = 6/1 or slope of 6.

How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?
Answers
Answer:
To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:
Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.
Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.
Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.
Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.
Use mental math to add the terms, which gives you a result of 15.8.
Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.
Step-by-step explanation:

Answer: Y = 3/8
Step-by-step explanation:
You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this
8,3
0,0
8,3
Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!
y = 3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.
What is proportional?In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.
If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.
This definition is frequently broadened to include associated varying amounts, also known as variables.
We can see that when y = 1.5, then x = 4
And when y = 3, x = 8
Putting the value in slope form
y - y1 = m(x - x1)
3 - 1.5 = m(8 - 4)
1.5 = m(4)
m = 1.5/4
m = 3/8
Now simply we put the value in y-intercept form
y - 3 = 3/8(x - 8)
y = 3/8(x) - 3 + 3
y = 3/8(x)
