Answer:
<h2>y=60+25h+0.3r</h2>
Step-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
Answer:
Domain: {-2,0,-1,4}
Range: {4,2,3,-2}
Step-by-step explanation:
1. Given the The relation Q={ (-2, 4), (0, 2), (-1, 3), (4, -2)}, you can determine the domain and the range as following:
DOMAIN:
The domain is the x-coordinate of each ordered pair. Therefore, you have:
Domain: {-2,0,-1,4}
RANGE:
The range is the y-coordinate of each ordered pair. Therefore, you have:
Range: {4,2,3,-2}
Answer:
26m
Step-by-step explanation:
a^2+b^2=c^2
24^2+10^2=c^
576+100=c^2
676=c^2
√676=√c^2
26=c
-5 + 9 = 4
-5 - 9 = -14
4 and -14 are both 9 units from -5 on a number line
2/7 = 630/x
2x = 7 × 630
2x = 4410
÷ 2
2205 = x
2205 applied
