Answer:
13 cms
Step-by-step explanation:
By Pythagoras:-
x^2 = 12^2 + 5^2
x^2 = 144 + 25
x^2 = 169
x = √169
= 13
Answer:
y = -x + 1
Step-by-step explanation:
The slope-intercept formula is y = mx + b where m is the slope and b is the y-intercept. Since slope is...

this means that the slope of the line is -1 (the rise is -1, the run is 1, -1/1 = -1). By looking at the graph you can also see that the line goes through 1 on the y-axis, so the y-intercept is 1. By plugging in the appropriate values, the equation of the line is y = -1x + 1 or just y = -x + 1
320 cups of soup
Step-by-step explanation:
2:5 is a part to whole ratio.
2/5=x/800
so we cross multiply to get:
5x=1600
x=320

Step-by-step explanation:
Answer: 4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get,
+ 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
