Answer:
y= 6/5x -8
Step-by-step explanation:
The slope-intercept form (basically the form for the equation of a line)
y=mx+b
m is the slope
x is the value you want to plug in, or the x term in a point (x, y)
we know so far,
y=6/5x + b
so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope
-2 = 6/5(5) + b
6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6
so
-2 = 6 + b
subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)
-8 = b
2. 3/4(-4 + 4x) = -3 + 3x 3/4 times 4 is 3, so if you distribute 3/4 (-4 + 4x), you will get -3 + 3x.
3. -0.113(-4x - 4) = 0.452x + 0.452 0.113 times 4 is 0.452, but you need to make sure to have the correct signs. Since the product is positive and -0.113 is negative, you would have to multiply it by a negative to get the product.
If you're having trouble with multiplying by fractions, just use repeated addition in your head. For example, for the first problem, instead of trying to tackle 3/4 times 4, think 3/4 + 3/4 + 3/4 + 3/4.
3/4 + 3/4 = 6/4
6/4 + 3/4 = 9/4
9/4 + 3/4 = 12/4
12/4 = 3
For the second problem, when multiplying by a decimal, just do what you'd normally do for multiplication. When you get to the end, count how many digits you had behind the decimal before, and put the decimal in the corresponding space for the answer.
0.113
x 4
0452
There are 3 digits behind the 0 in 0.113, so there should be 3 digits behind the decimal in the answer. So, the answer should be 0.452.
Hope this helps!
Answer:
C. 5/3 (5 sqrt 3) (8.66...)
Explanation:
You would use the SohCahToa to find out side x.
First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).
Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.
Third, once you figure that out then plug stuff in...
Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X
I’m pretty sure This rounds to 900
Answer:
It's 4 (B)
Reasoning:
When X is equal to its lowest point (1 in this case, but it's usually 0), y is equal to 4
I hope this helps and good luck!
