Answer 1

Answer:

x=7.48

Step-by-step explanation:

13^2+x^2=15^2

169+x^2=225

x^2=56

x=7.48

Answer 2

Answer:

x =     7.48 (2d.p.)  or 7.5 (1 d.p.)

Step-by-step explanation:

Use Pythagoras' Theorem.

15 x 15 (or 15²) = 225

13 x 13 = 169

√H - A = O

225 - 169 = 56

√56 = 7.48 (2d.p.)  or 7.5 (1 d.p.)

slope. Choose two points. For the sake of explainin, I am choosing

(-3,1)

and (0,3). That’s the y intercept!!

The slope is the rate of increase. We have to measure it like we do with stairs. The rise divided by the run

the rise is 2. See the picture. The run is 3(change in x) the x increases by 3 between 2 integer points while the y changes by 3(change in y —>3 minus 1)

Rise= 3

run =2

Slope=rise/run=3/2
