What is the answer to 1-5

1. EFG

2. F

3. FA and FB Take a moment to look at this one. The two rays are pointing in opposite directions. They are 180o apart. They share a common point at F.

FE and FG does the same thing.

4. No G is on a line that has only one point on the plane and that point is F.

5, AC has an infinite number of points on the plane.

Fareed wants to add 1/4 +5/8 Add the fractions by using the giant one to create a common denominator

saul85 [17]

Hi!

This question is about math.

$\frac{1}{4}+\frac{5}{8}$

Least Common Factor 4 or 8: 8

Factors of 4 : 1, 2, 4 (prime factorization) (2*2)

Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)

Least Common Factor of a,b is the smallest positive number that divisible by both a and b.

Multiply each factor the greatest number of times it occurs in either 4 or 8.

Then multiply by the numbers.

$2*2*2$

$=8$

Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.

For 1/4 multiply the denominator and numerator by the 2.

$\frac{1}{4}=\frac{1*2}{4*2}=\frac{2}{8}$

$\frac{2}{8}+\frac{5}{8}$

Since the denominator are equal, combine the fractions.

$\frac{2+5}{8}$

Add the numbers 2+5=7

$=\frac{7}{8}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $69. A season ski pass costs $350. The

zalisa [80]

Divide the season pass cost by the daily capstone:

350 / 69 = 5.07

They would have to ski 6 days for the season pass to be less expensive

5. h(x)=0.5x - 1 with domain (-♾, 4) what is the range

Rudiy27

We have a domain of a function, that is, which x-es can we throw in. But we are asking which y-s will we get given that we can only throw x-es in $(-\infty,4)$ .

Let's try $x=4$ even though we are forbidden to put 4 inside $h$ we are still able to do so.

So $h(4)=0.5\cdot4-1=2-1=1$ what we just got is the upper limit of the range. The lower limit is $h(-\infty)=-\infty$ .

So the range is just $(-\infty, 1)$ .

Hope this helps :)
