Answer:
D
Step-by-step explanation:
There is more than one way to solve this; the easiest way is to plug in some numbers for x. We can see the roots are (3,0) and (7,0) and the lowest point is (5,0). So when we plug in 3 or 7, we should get zero.
B: (3-3)(3-7)=0
D: 3(3-3)(3-7)=0
So we have two possible solutions, So to check, let's find a point where we can easily find the y value.
When x is equal to 4,5, or 6, there is an integer value for y. so let's plugin 5:
(5-3)(5-7)=-4
We can see when x is five, y has to be -12, so that is not the answer, thus d is the final answer.
The answer is the average shoe size is 10 because mean is average.
Answer:
1/4 is the number
a.k.a. 0.25
Step-by-step explanation:
Replace the words "a number" with x
4x + 2 = 3
Then, simplify
4x = 1
x = 1/4
Answer:
Step-by-step explanation:
So we know two points of a line and we want to find the equation of the line.
First, let's use the two points to find the slope.
The slope formula is:
Let's let (3,1) be x₁ and y₁ and let's let (2,5) be x₂ and y₂.
Therefore:
Simplify:
So, our slope is -4.
Now, let's find our equation using the point-slope form. The point-slope form is:
Let's continue to use (3,1) as x₁ and y₁. Our m or slope is -4. Thus:
Distribute the right:
Add 1 to both sides:
And we're done!
