6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19
Answer:
B) 10
Step-by-step explanation:
4x+5=45
-5 -5
4x=40
/4 /4
x=10
Calculate The mode of this set of numbers 2,5,1,6,3,8,5,9,2,4,7
koban [17]
The mode is 5 & 2 because they both appear the most and the same amount of times that’s why they’re both the mode.
Answer:
here,
principle(p)=£8000
time(t)=5 years
rate(r)=10%
now,
Interest=PTR/100
=8000 x 5 x 10/100
=£4000
Step-by-step explanation:
