Answer:
a
Step-by-step explanation:
In ax+by=c form
slope=-a/b
y intercept is when x=0
sloope of 2x-5y=12 is -2/-5=2/5
y intercept of 4y+24=5x
4y+24=5(0)
4y+24=0
4y=-24
y=-6
y int=-6
y=mx+b
m=slope
b=y intercept
y=2/5x-6
answer is 2nd optoin
Answer:
d. $10,234.80
Step-by-step explanation:
we are given
The equipment will cost $26,000
so, Amount is $26000
A=26000
should be invested today at 12%
r=12%=0.12
It is compounded semiannually
so, n=2
t=8
now, we can use formula

now, we can plug values

now, we can solve for P

Answer:
7.8 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 48 = x/7
7 tan 48 = x
7.774287604 = x
To the nearest tenth
7.8 =x
Let's assume money in Josie's purse to begin with as 'x'
There are 18 markers
Each marker cost $1.20
so, we can find total cost of markers
Total cost of markers = ( total number of markers)*(price of each marker)
so, we can plug value
Total cost of markers is

$
now, we are given
Josie spent 4/7 of the money in her purse on some books
the rest of the money on 18 markers
so, rest money is


and this rest money is total cost of markers
so, we can set them equal and then we can solve for x




So, total money in Josie's purse in beginning is $50.4..........Answer
