The slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.
<h3>What is the slope-intercept form of the given equation?</h3>
The slope-intercept form is expressed as;
y = mx + b
Where m is the slope and b is the y-intercept.
Given the equation in the question;
8x + 10y = -30
To convert to slope intercept form, we make y the subject of the formula and simplify.
8x + 10y = -30
10y = -8x - 30
Divide each term by 10
10y/10 = -8x/10 - 30/10
y = -4x/5 - 3
y = (-4/5)x - 3
Therefore, the slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

Friving in opposite directions, Joe and Hannah become (45+40)= 85 more miles apart rvery hour. They are 510 miles apart after (510/85)= 6 hours.
Answer:
Step-by-step explanation:
Hello!
An observational study is one where the investigator has no control or intervenes on it. He just defines the variable of interest and merely collects and documents the information.
An experimental study or experiment is one where the investigator intervenes by defining the variable of interest and artificially manipulates the study factor. It is also one of its characteristics the randomization of cases or subjects in groups (two or more, depending on what is the hypothesis of study).
1)
In the first example, the researcher doesn't control anything about the experiment, he just asks the professional musicians their age.
This is an observational study.
2)
In this second example, there is also no intervention of the researcher, she just asks her employees where they eat their lunch. This example is also an observational study.
I hope you have a SUPER day!
2 1/8 + 1 3/4
3/4 = 6/8
1/8 + 6/8 = 7/8
2 + 1 = 3
3 + 7/8 = 3 7/8
There is a total of 3 7/8 cups of flour.
Divide both length and width by the dialtion factor and that will be the dimensions of the new rectangle. 2.5714in by 3.4286in. Round as needed
