Answer:
Final solution = -10
(-9)+4+6+(-11)
-9 + 4 +6 (+-11) you need to show
-9 +4 +6 + (-11) calculator shows
= -5 + 6-11 is both results.
= 1-11
= -10
Answer:
y= -2x + 7
Step-by-step explanation:
I did the math and the slope was -2 and the y-intercept was 7
1 1/5, 1.25,! 3/4 and 5 continues forever...Brainliest?
Answer: 0.036
Work Shown:
6 red, 6+3+7 = 16 total
A = 6/16 = probability of getting red the first time
after you pick 1 red, there's 6-1 = 5 left out of 16-1 = 15 total
B = 5/15 = probability of getting red the second time
then you repeat: 5-1 = 4 red left out of 15-1 = 14 total
C = 4/14 = probability of getting red the third time
B and C are dependent on A, C is dependent on B. This is assuming we do not put any marbles back.
Multiply out the fractions found
A*B*C = (6/16)*(5/15)*(4/14) = 0.0357 which rounds to 0.036 when rounding to the nearest thousandth.
Answer:
100 brochures
Step-by-step explanation:
<u><em>The complete question is</em></u>
The organizers of a walkathon get cost estimates from two printing companies to print brochures to advertise the event. The costs are given by the equations below, where C is the cost in dollars and n is the number of brochures.
Company A: C=15+0.10n
Company B: C=0.25n.
For what number of brochures are the cost the same for both company’s
Let
n ---> the number of brochures.
C ---> the cost in dollars
we have
<em>Company A</em>
----> equation A
This is the equation of a line in slope intercept form
where
The slope or unit rate is
![m=\$0.10\ per\ brochure](https://tex.z-dn.net/?f=m%3D%5C%240.10%5C%20per%5C%20brochure)
The y-intercept or initial value is
![b=\$15](https://tex.z-dn.net/?f=b%3D%5C%2415)
<em>Company B</em>
----> equation B
This is a proportional relationship
where
The constant of proportionality or slope is
![m=\$0.25\ per\ brochure](https://tex.z-dn.net/?f=m%3D%5C%240.25%5C%20per%5C%20brochure)
To find out for what number of brochures are the costs the same for both companies, equate equation A and equation B
Solve by substitution method
![0.25n=15+0.10n](https://tex.z-dn.net/?f=0.25n%3D15%2B0.10n)
solve for n
![0.25n-0.10n=15\\0.15n=15\\n=100\ brochures](https://tex.z-dn.net/?f=0.25n-0.10n%3D15%5C%5C0.15n%3D15%5C%5Cn%3D100%5C%20brochures)
