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.
Answer:
I think the answer is -12r^3x^2y^7
Y=18.
All triangles are 180 degrees. The given angle is 108 degrees. 180 - 108 = 72. 72 degrees are left to solve for in the triangle. 72 degrees / the two angles = 36. The angles of the triangle are 108, 36, 36. The 36 degree angle = 2y. 36 / 2 = 18.
Y=18
answer
x=6,y=14
Step-by-step explanation:
make -5x+5x=40 as equation (1)
4x+3y=24...... (2)
Find equation (3) from (1)
-5x+5y=40
-5x/-5=(40-5y)-5
x= y-8............. (3)
Substitute (3) from (2)
4x+3y=24
4 (y-8)+3y=24
4y-32=24
4y=24+32
4y=56
y=14
find x from equation (3)
x=y-8
x=14-8
x=6
