Y = 22
y= 3x+4
y=3(6)+4
y=18+4
y=22
Answer: 22.5 minutes
Step-by-step explanation: Daisy ran 12 miles in 90 minutes so we should first figure out how many minutes it took her to run a mile. So 90/12 would get us that. 90/12 turns out to be 7.5 minutes per mile. Since she runs at a constant rate we multiply 7.5 by 3 (7.5*3) to get 22.5 minutes for 3 miles.
C. 1/root2
Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.
Answer:
1st Side: 27 inches, 2nd Side: 23/2, 3rd Side: 67/2
Step-by-step explanation:
Let's solve your problem step by step:
First side should be: 2x+4
Because 2 times the second side =, and 4 longer than that.
Second side should be: x
This is the base of the equation, since all the numbers depend on "x"
Third side should be: (3x+4)-5
Because x + x+4, and the third side is 5 shorter..
We add all and we get 72.
Solve for x.
x=23/2
Now, we can solve for other sides, by doubling it and adding 4.
This is answer is correct, I tried it. :)
You have to plug in 0 to each variable and solve to get each axis intercepts giving you. (0,-3) (6/5,0)
