Answer:
-37
Step-by-step explanation:
1) to find the equation of the given line (its slop-interception form is y=mx+i, where m - slop, i - interception):
a) y=2x+i, where m=2;
b) it is possible to calculate the value of 'i' after the substitution the point (5;-3) into the equation y=2x+i:
-3=2*5+i; ⇒ i= -13;
c) the equation of the given line is y=2x-13.
2) to calculate the value of 'R':
if to substitute the point (-12;R) into the equation y=2x-13, then
R=2*(-12)-13; ⇒ R= -37.
7/8 is tricky to do on a computer, but I will say that it is 87.5 percent or 0.875.
Do you know how to do normal long division? This is like that. Just after the decimal point, drop a 0 down.
I hope this helps!
A 180º rotation around the origin changes the coordinates from (x, y) to (-x, -y).
A translation 7 units up increases the y value by 7 units.
A reflection over the x-axis results in the y-values being opposites.
My apologies this is only for a reward to ask questions myself .
