Answer:
1080 boys
Step-by-step explanation:
2400 x 0.45 = 1080
Answer:
2. for the first equation, it works, for the second it doesnt so the answer is no
i cant graph for you, but its easy, just use y=mx+b m being the slope which is rise over run
8. x=6, y=-1
10. x=-5 y=5
this is all i could do in such a short notice, but i hope it helped you!
Step-by-step explanation:
for 8, 
for 10,
Answer:
3.496
Step-by-step explanation:
Multiply these two by getting rid of the decimal:
38 -<em>decimal is moved one place here.</em>
<u>x092</u> -<em>decimal is moved two places here.</em>
3496 -move decimal three places over.
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.
b= square-root of (c^2)-(a^2)
b= square-root of (9^2)-(2^2)
b= 8.77.... which in the exact form is square root of 77.
To find the slope, we must use the formula stated below.
Slope = Change in Y / Change in X = (Y1 - Y2) / (X1 - X2)
Since our coordinates are given as (X, Y), we must pick a coordinate to be #1, and the other coordinate will be #2.
I'll use the first coordinate as our #1.
(3 - 6) / (2 - 7) = (-3) / (-5) = 3/5 which is our answer
