Find the point of the intersection for the given systems y=x^2+1 and y=x+1
mario62 [17]

set them equal to each other

x²+1=x+1

minus 1 from both sides

x²=x

minus x both sides

x²-x=0

factor

x(x-1)=0

set each to 0

x=0


x-1=0

x=1


subsitute back to find y values

y=x+1, y=0+1, y=1, one point is (0,1)

y=x+1, y=1+1, y=2, another point is (1,2)


the 2 points of intersection are (0,1) and (1,2)

Still can’t get the answer
Eddi Din [679]

Answer:

Arliss needs 4 \frac{1}{3} yards more.

Step-by-step explanation:

We can look at the fractions 2 \frac{1}{3} and 3 \frac{1}{3} and add them up.

Looking at the whole numbers, 2+3=5.

Looking at the fractional parts, \frac{1}{3} +  \frac{1}{3} = \frac{2}{3}.

So all together, she currently has 5 \frac{2}{3} yards.

If she wants to get to 10, we need to find how many more yards we need.

Let's level it out quickly - having \frac{1}{3} more of a yard will give is 6 yards.

10-6=4, so in total we added

4 \frac{1}{3} more yards.

So she needs 4 \frac{1}{3}  more yards.

Hope this helped!

On a coordinate grid, point P is at (2, 1) and point R is at (−6, −5). Points Q and S are a reflection of both points across the
belka [17]
Since you're reflecting both points across the x axis they'll be the same, but flipped.
S will be (-6, 5) and Q will be (2, -1)
