Answer:
60cm^2
Step-by-step explanation:
15 times 8 = 120
divided by 2 = 60
Answer:
x=3
Step-by-step explanation:
-2x+3=x-6
-3x+3=-6
-3x=-9
-x=-3
x=3
Answer:
-2
Step-by-step explanation:
We can find the slope by using the slope formula
m = (y2-y1)/(x2-x1)
= (-5 - -7)/ ( -2 - -1)
= ( -5+7) / ( -2 +1)
= 2/-1
= -2
Two straight lines perpendicular to each other, the slope of which is negative reciprocal.
y=-4/3x+b
The known points are put into the linear equation
y=-4+b
b=13
y=-4/3x+13
