Slope intercept: y = mx + b
Y = 9x + b, plug in point
9 = 9(0) + b, b = 9
Solution: y = 9x + 9
Answer: 55.1°F
Step-by-step explanation:
We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:
= 1.6° × 2
= 3.2°F
If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:
= 58.3°F - 3.2°F
= 55.1°F
Answer:
x=−8 and y=−4
Step-by-step explanation:
8x−17y=4;−8x+15y=4
add eqn1 and 2
to eliminate x
you will get y=-4
put it zin eqn 1
x=-8
<em><u>0.9506</u></em>
Step-by-step explanation:
here's the easy explanation:
We have 2% and 3%.
Take them both away from 100 since we're decreasing!
<em>100 - 2 = 98</em>
<em>100 - 3 = 97</em>
Divide them both by 100.
<em>98 --> 0.98</em>
<em>97 --> 0.97</em>
Times them both together!
<em>0.98x0.97 = 0.9506</em>
