QUESTION POSTED AT 18/01/2020 - 07:15 AM

Ok so
for a right triangle with legs legnth a and b, and hypotnuse legnth c
a^2+b^2=c^2

hypotonuse is 13
one leg is 12
other leg is ?
a=12
b=?
c=13

sub and find ?
12^2+?^2=13^2
144+?^2=169
minus 169 both sides
?^2=25
sqrt bot sies
?=5

### In 4 years, harry’s age will be the same as jim’s age is now. in 2 years, jim will be twice as old as harry will be. find their ages now.

The answer to this question would be:
Jim     =6 years
Harry =2 years

To answer this question, you need to translate the description into a  mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J
2. (J+2)= 2(H+2)
J+2= 2H+4
J= 2H +2

If you put the 1st and 2nd equation together, the result would be:
H+4= J
H+4= (2H +2)
H-2H= 2-4
-H= -2
H=2

After that insert the H value to either 1st or 2nd equation.
H+4= J
2+4=J
J= 6

We can reduce the fractions or rates to their lowest term by dividing the numbers by 4 such that,
(1) 3 pages / 5 minutes
(2) 5 pages / 8 minutes
Therefore, the rates are not equivalent.

### Find the range of the function y=-5x-7

Range is how far up or down the garph can go
basically the limits of y

find min and max of y

basically find the biggestor smallest the x can get to influence y
confusing sorry
when x is an even number, that number is still negative

so make that number as small as possible
if x=(big number that is negative)
we get -1/(5^(big number)) which basically makes it nigligible or almost 0

y=-7 is max

when x=big number (positive) we get very negative number

so range is from negative infinity to -7
basically y<-7
we choose < and not ≤ because the -5ˣ will never dissapear, it will just be very, very small

### Two sides of a triangle measure 5 in. and 12 in. Which could be the length of the third side? 3 in. 6 in. 10 in. 18 in.

The possible answer is 10 in.

Step-by-step explanation:

Two sides of a triangle measure 5 in. and 12 in.

If three side of triangle are a, b and c then sum of two side is always greater than third side.

Sum of two side greater than third side.

a+b>c

a+c>b

b+c>a

Difference of two side is less than third side.

a-b<c

b-c<a

a-c<b

Here, we are given two sides of a triangle 5 in and 12 in.

Possible length of third side be

12-5 < c < 12+5

7<c<17

Third side must be lie between 7 to 17.

According to option, Third side must be equal to 10 in.

Hence, The possible answer is 10 in.
