Answer:

3.C

Step-by-step explanation:

the line is going down so the slope is negative and the y intercept is 4. also to find the slope fine a point for example 1,1 so either go up or down the the next point like 0,4 so it up 3 and over one which is 3/1 which is just 3.

4.c

for the slope you go up 5 over 1 for and for the y intercept will always gave 0 and something beside it but sense it us 0 then you just done have one also you can just plot the points and make a line as well.

Express 15.16 as a mixed number
kap26 [50]
If this is not a typo, and you mean 15.16 as in 15 and 16 hundredths, we can express this into a mixed number.
Mixed numbers are a whole number with the remainder of that number as a fraction.
For example, 1.25 as a decimal = 1 1/4 as a mixed number.
Since we already have our whole number, 15, we need to know what 16 hundredths is simplified as a fraction.
Currently, our mixed number is 15 16/100.
To simplify this, we need to find a common factor that 16 and 100 share.
Since they are both even numbers, let's divide by 2.
16/2 = 8
100/2 = 50.
Our new mixed number is 15 8/50.
Currently our fraction is still even, so divide by 2 again.
8/2 = 4
50/2 = 25
Your new mixed number is 15 4/25.
4 and 25 have no common factors, so the fraction is simplified.
Your answer is:
15.16 is 15 4/25 as a mixed number.
I hope this helps!

Find the value of x.
zimovet [89]

Answer:

x = 30

Step-by-step explanation:

We know that the angle is a right angle, which is equal to 90. So in order to see what the equation is equal to, we have to subtract 81 from 90.

90 - 81 = 9

With the answer we get, we can now begin to solve for x.

2x - 51 = 9, add 51 to both sides

2x = 60, divide 60 by 2 to get x

x = 30

Now, to check your work, plug 30 into the equation.

2(30) - 51

60 - 51 = 9

hope this helps!! :]
