Using the formula y=mx+b, you can simplify the equation to y=-4.5x+28 which means that the slope (m) equals -4.5 and the y-intercept (b) equals 28.
Answer:
175
Step-by-step explanation:
5/24 = 0.208 percentage of defective bolts
scale up to 840 bolts by finding 20.8% of defective bolts
840*20.8 = 175
Answer:
Perimeter = 14
Area = 
Step-by-step explanation:
If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².
We have the ratio:

Area of the smaler triangle = x
Area of the larger triangle = 567 cm²
Therefore we have the equation:

<h3>Answer: C. 63 cm²</h3>
Total miles:350+150=500
Total hours:4+3=7
Avg speed:500/7=71.429 mph
