Answer:
y = -2x + 9
Step-by-step explanation:
The slope of the line can be found from 2 points.
(y2-y1)/(x2-x1)
7-3/1-3
4/-2
= -2
-2 is the slope.
The y-intercept is 9.
The equation of a line is y=mx+b.
m is the slope, and b is the y-intercept.
y = -2x + 9
Solving the questions below we use PEMDAS
that is:
parenthesis, exponential, multiplication, division, addition then lastly subtraction.
1) 12×43+43×88
In this situation we begin by multiplication first:
516+3784
Next we add the result
4300
2)23×77+77×77
we multiply first
1771+5929
next we add them
7700
3) <span>3) 45∙123−45∙80+45∙57
We multiply first
5535-3600+2565
next we add the positive numbers then lastly we subtract the results
8100-3600
subtracting gives us:
4500
4)</span><span>1341</span>×<span>12−12</span>×<span>1241
First we multiply the numbers
16092-14892
next we subtract:
1200</span>
Answer:
A would be at (-2,5) if reflected across the y axis
Answer: points B (4,7) and I (9,3)
If the inequalities are
y > −2x + 10 and y> (½)x -2
Step-by-step explanation: If I interpreted the inequalities correctly, the attached graph shows them. It is possible that you meant y > 1/(2x-2) for the second inequality. If so, we start over!
You can test the values for all the points, but it appears that (4,7) and (9,3) both work.
The other coordinates appear to be outside the solution -- the dark-shaded area.
I hope this is your Brainliest answer. It was a lot of work!
