Answer: D. (0,10)
Why:
Your given equation is 5x+2y=20, so in order to find the y-intercept, we must put it in slope-intercept form, a.k.a. y=max+b.
To do this, subtract 5x from both sides. This will then give you 2y=-5x+20.
And to fully simply, divide both sides by 2. Finally, you get y=(-5/2)x+10. And since we know b in slope-intercept form is the y-intercept, and 10 is b in our final function/equation. We get the answer of y-intercept=(0,10)
Answer:
40
Step-by-step explanation:
12 is 30% of 40
30% x X = 12 or 30/100 x = 12
so if you multiply both sides by 100 and divide both sides by 30
we get X = 12 x 100/30
= 40
(BTW if you want to use a calculator just put 12×100÷30 which will give you the answer)
Answer: Option A
Step-by-step explanation:
Given the parent function , it can be transformated:
If , then the function is shifted k units down.
If and it is vertically stretched it, but if it is vertically compressesd.
If , then the function is reflected over the x-axis.
Then, if the function given is reflected over the x-axis, it is vertically streteched by a factor o 2 and it is shifted down 1 units, the function that results after this transformations is:
