Answer:
39x - 63
Step-by-step explanation:
5(3x - 3) + 4(6x - 12) ← distribute both parenthesis
= 15x - 15 + 24x - 48 ← collect like terms
= 39x - 63
Answer:
y=1/2x+1
Step-by-step explanation:
First use slope formula.
Plug in the information needed.
The slope is .
Now, use point-slope formula.
y-y1=m(x-x1)
Plug in the information needed.
y-3=1/2(x-4)
y-3=1/2x-2
y=1/2x+1
The equation of the line in slope-intercept form is y=1/2x+1.
Hope this helps!
If not, I am sorry.
Answer:
You can choose trivial values such as , but also something like if you feel more daring. Both equations will come out to yield , which is obviously true.
Step-by-step explanation:
Because the answer is true for all , any two values can be chosen. It is most often useful to choose easy values of for these kinds of situations, though.
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
Phil will have 36 rocks, and since Phil has 3x more than Peter, you take 36/3 which equals 12, 12+36=48. then to find the difference you take 36-12 which equals 24
