Answer:
7 - ?
Step-by-step explanation:
Write and expression like and you should have a right answer. Hope this helps and good luck :)
Step-by-step explanation:
"Solutions to the equation" just means that they are points on the line. To find out if these two points land on this line, plug each one in, like this:
1.5 = (1/4)(1) + (5/4)
1.5 = (1/4) + (5/4)
1.5 = (6/4)
1.5 = 1.5
Since the expression is true, this point is on the line.
Do the same process for the second point (remember a point is formatted (x,y)) and see if it is also a point on the line.
To find the x-intercept, simply plug in 0 for y and see what you get. It should look like (x,0).
Multiply first example by 3 and subtract by second example, you will get the following:
3*(5x + 2y) = 3*22 => 3*5x + 3*2y = 66 => 15x + 6y = 66
now subtraction:
(15x + 6y) - (-2x + 6y) = 66 - 3
15x + 6y + 2x - 6y = 63
15x + 2x + 6y - 6y = 63
17x = 63
x = 63/17 ≈ 3.705..... and as it says to round to the nearest tenth our answer would be: x = 3.7

I need help with this too
Step-by-step explanation:
Answer:
120 degrees
Step-by-step explanation:
Ok, so if you know that 5 is 120 degrees then 1 is 120 degrees because the angles will be corresponding when it is a set of lines that are parallel bisected by a line. So 1 is corresponding to 5 and 2 to 6 and 3 to 7 and 4 to 8.
