Answer:
slope 2.500
x intercept 1.80000
m intercept 4.50000
Step-by-step explanation:
<u>step 1:</u>
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x+4)-(-2*(-4-m)+3)=0
<u>step</u><u> </u><u>2</u><u>:</u>
-4 - m = -1 • (m + 4)
(5•(x+4))-((0--2•(m+4))+3) = 0
<em>step</em><em> </em><em>3</em><em>:</em>
5 • (x + 4) - (2m + 11) = 0
<u>step</u><u> </u><u>4</u><u>:</u>
5x - 2m + 9 = 0
<u>step</u><u> </u><u>5</u><u>:</u>
Solve 5x-2m+9 = 0
Answer:
The length of the long side of the rectangle is 38 ft.
Step-by-step explanation:
If we test out all possible factors, we will see that 15 x 38 is the most fitting.
Perimeter: 15 + 15 + 38 + 38 = 106 ft.
Area: 15 x 38 = 570 square ft.
38 ft. is the measurement of the long side and 15 ft. is the measurement of the smaller side.
Answer:
60 kilometers per hour (kmph) over the limit
Step-by-step explanation:
The speed limit is 60 kmph
Let's find his original rate:
We know D = RT
Where
D is the distance, in km
R is the rate, in kmph
T is the time in hours
He went 10 km in 5 minutes, so we need the time in hours, first. That would be:
5/60 = 1/12 hour
So, putting into formula, we find rate:
D = RT
10 = R(1/12)
R = 10/(1/12)
R = 10 * 12
R = 120 kmph
He was going over by:
120 - 60 = 60 kmph
