Answer:
Her average speed was 48..88 mph
Step-by-step explanation:
Use a rule of 3 to find the time she traveled at 60 mph:
60 miles ----------1 hour
40 miles ---------- x
60x = 40
x = 40/60 = 0.67 hours
She traveled 40+50= 90 miles
During 1.25+0.67= 1.92 hours
90/1.92 = 48.88 mph
The sum's degree will be equal to the highest degree of the two polynomials. Out of the two polynomials being added, the higher degree is 5. The sum will be degree 5.
Hello from MrBillDoesMath!
Answer:
Choice B
Discussion:
The answer shown highlighted is the correct answer
For a function, each value in the domain should be assigned a unique value in the range. In the case of ordered pairs, each x value in an order pair should have a unique y value. This aspect fails for Choices A, C, and D. Details follow.
Choice A: Not a function because (3,3), and (3,2) both have x = 3 but associated y value is not unique (equal 3 or 2)
Choice C: Not a function because (1,-1) and (1, -2) both have x = 1 but associated y value is not unique (equals -1 or -2)
Choice D: Not a function because (2,3) and (2,1) both have x= 2 but associated y value is not unique (equals 3 or 1)
Choice B has no such issues as an x value is repeated.
Thank you,
MrB
The answer is 17s + 13.7 + 3.6t.
All you need to do to find the perimeter is to add all the sides.
(7.1s+9.6) + (9.9s-1.7) + (3.6t+5.8)
(7.1s+9.9s) + (9.6-1.7+5.8) + (3.6t)
(17s) + (7.9+5.8) + (3.6t)
17s+13.7+3.6t
Answer:
Step-by-step explanation:
THe slope intercept form of a line is y = mx + b
Where, m is the slope with formula
and
b is the y-intercept (the point where the line cuts the y-axis)
x_1 and y_1 is the first pair of points
x_2, y_2 is the second pair of points
<em>Let's find m first by plugging in the points:</em>
<em></em>
<em />
<em>Now we have y = 1/3x+b. We can plug in any point (let's use (1,0)) and find b:</em>
<em></em>
<em />
<em>THus, the equation of the line is </em>
