Part a:
this is really just intuition. you can go either way as long as you back up what you say.
either you think hunter would be faster because he starts out with a lot more money, or you think amado would be faster because he earns a lot more.
part b:
let x be the number of hours hunter works, and y the number that amado works.
they both need to earn 600 dollars.
hunter's money is modelled by 150 + 7.5x
to get 600 dollars
150 + 7.5x = 600
7.5x = 450
x = 60
amado's money is modelled by 12y
to get 600 dollars
12y = 600
y = 50
hunter would need to work 60 hours to make enough money, but amado would only need to work 50, so hunter will take longer.
then say whether this agrees with what you guessed in part a
<em><u>Explore Motors dealership has R7 million to spend and wants to buy equal numbers of the entry.</u></em>
Answer: 195 CM
Step-by-step explanation:
Volume: Length x Width x Height
“First we have to break it into 2 shapes”
“Let’s solve the top shape!!”
The length is 5 the width is 3 and the height is 4.
Volume = 5 x 3 x 4 = 60
Now the bottom shape
The length is 9 the Width is 5 and the Height is 3
The height isn’t given so we must do some math
Subtract the 7 from 4 = 7 - 4 = 3
Volume = 9 x 5 x 3 = 135
Finally, 135 + 60 = 195 cm
Answer:
Step-by-step explanation:
Let's do like-terms first which on the right side has the 2p:
17-2p=4p+5
Then make the variables on one side:
17=4p+2p+5
17=6p+5
Let's put that 5 on the other side:
17-5=6p
12=6p
Lastly, divide 6 to get a final remaining p.
12/6=p
2=p
Hope you understand :)
Answer:
Step-by-step explanation:
Refer to attached for points
a) f(-1) = 3 as per graph
b) f(x) = 6
We add horizontal line through point y=6 to find intersections with the graph
Take x-values of those points. The points are x = -3, x = -2, x = 2
