A cell phone company charges $45 per month for unlimited calls and $0.25 per text messages. Another call phone company $0.15 per text messegaes and $70 per month for unlimited calls. Write an equation to reoresent when the cost from both compsnies will be the same after one month
Answer:
You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Answer:
140
Step-by-step explanation:
x = 7 ; y = -2

7/15 - 2/5
please can someone do a step by step? thank you
Answer:
1/15
Step-by-step explanation:
1.) Make the denominator equal by turning the 5 into a 15 (In order to subtract it properly)
2.) Make the 2 correspond with the denominators. In this case multiply by 3 because 5 goes in to 15 3 times. Equation Now: 7/15 - 6/15
3.) Subtract the numerators to get your answers
4.) Final Answer: 1/15

PLZ MARK ME AS BRAINLIST
A manager of the credit department for an oil company would like to determine whether the mean monthly balance of credit card holders is equal to $75. An auditor selects a random sample of 100 accounts and finds that the mean owed is $83.40 with a sample standard deviation of $23.65. If you were to conduct a test to determine whether the auditor should conclude that there is evidence that the mean balance is different from $75, which test would you use? a) Z-test of a population mean b) Z-test of a population proportion c) t-test of population mean d) t-test of a population proportion
Answer:
c) t-test of population mean
Explanation:
The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.
Example we compare our test variable to the hypothesized mean value $75 above.
The t test is used instead of z score when standard deviation is unknown.
Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.
What is the vertex of this parabola? y= 2x² + 4x +5
Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )
Convert the following equations from point-slope form to slope-intercept form.
9) y – 4 = 3(x – 1)
10) y – 1 = -4(x – (-3))
We need to solve both for y.
#9:
[tex]y - 4 = 3(x - 1)\\\\y - 4 = 3x - 3\\\\y = 3x + 1[/tex]
#10:
[tex]y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11[/tex]

Klein opened a savings account that paid 5% simple interest with 6,000 in principal. If Klem left that money untouched in the account for ten years,then how much interest with he have earned?
Answer:
I= $3,000
Step-by-step explanation:
Giving the following information:
Klein opened a savings account that paid 5% simple interest with 6,000 in principal.
Number of periods= 10 years
To calculate the interest earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
I= 6,000*0.05*10
I= $3,000
