Answer:
1.25 hours (Or 1 hour and 15 minutes) and 14 MPH
Step-by-step explanation:
1. If it takes 1 hour to travel 48 miles, then you can subtract it from the 60 miles, and have 12 miles left. Divide 12 by 48, and you get 0.25, so if you add it together, you get 1.25. To check, 48 x 1.25 equals 60.
2. 270 minutes is equal to 4.5 hours. Divide 63 by 4.5, and you'll get 14 miles per hour. To check, 4.5 x 14 equals 63.
Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)
Answer:
2x(2x - 1)(x + 3)
Step-by-step explanation:
4x^3 + 10x^2 - 6x =
Factor out the common factor 2x.
= 2x(2x^2 + 5x - 3)
Factor the trinominal.
= 2x(2x - 1)(x + 3)
Answer:
I think it's the last one D
Step-by-step explanation:
I'm not 100% sure, but I think the x can't repeat and 4 is the only number of x that hasn't been plotted yet. Tell me if it was right?
Answer:
Step-by-step explanation:
<u>Given</u>
- f(x)=2x-5
- g(x)=4x,
- f(g(3))= ?
<u>Solution:</u>
- g(3) = 4*3 = 12
- f(g(3)) = f(12) = 2*12 - 5 = 24 - 5= 19
