Answer:
60 km/h
Step-by-step explanation:
60/40=1.5
90/1.5=60
Answer:
Step-by-step explanation:
y = -x^2+4x-6x +24
y = -x^2 -2x + 24
Vertex (x) = 2/-2 = -1
Vertex (y) = -100/ -4 = 25
Vertex (-1, 25)
axis of symmetry: x= -1
-x^2 -2x + 24 = 0
Δ/4 = 1+24 = 25
x1 = (1 + 5)/-1 = -6
x2 = (1-5)/-1 = 4
left x intercept = (-6,0)
right x intercept = (4,0)
The DOMAIN is the set of all numbers
The range is y less than or equal to 25
see the attached figure to better understand the problem
Step 1
<u>Find the number of pages printed on an Apricot printer </u>
we know that
The speed of an Apricot printer is 8ppm
so
in 4.5 min
Carlos print
4.5*8=36 pages
step 2
<u>Find the time it takes Carlos to print the same amount of documents on a sure fire printer printer</u>
we know that
The speed on a sure fire printer is 12ppm
so
Divide the total of pages by the speed of the printer
36/12=3 minutes
therefore
<u>the answer is</u>
3 minutes
Move all terms to the side of the answer x = -8/7 Hope this helps! ;D
