Answer:
Same side interior angles of parallel lines are supplementary.
Step-by-step explanation:
5a + 10 + 3a + 10 = 180; 8a + 20 = 180; 8a = 160; a = 20; m<4 = 5xz + 10 = 5 * 20 + 10 = 100 + 10 = 110.
Answer: 82
Step-by-step explanation:
H=9(-3)^2+1
Simplify both sides of the equation.
h=81+1
81+1 =82
h=82
Answer:
Option The graph will be a dashed line with a y-intercept of negative eight and a slope of three. The graph will be shaded above
the line
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line The equation of the dashed line is 
The slope of the dashed line is positive 
The y-intercept of the dashed line is -8
see the attached figure to better understand the problem
I believe it is positive so option 2
X=numbers of hammers
y=numbers of scewdrivers
f(x,y)= total cost in $
f(x,y)=11x+6.65y
f(4,7)=4(11)+6.65(7)=44+46.55=90.55
Sol: an expresion for the total cost of the tools is f(x,y)=11x+6.65 y;
x=number of hammers
y= number of scewdrivers.
The total cost is $90.55
