Please help me. I don’t know which phone contract is better.
I am going to change my phone contract. The monthly contract I am considering costs $30 per month with 75 minutes of free calls and 100 free text messages. Additional calls cost 10¢ per minute and additional text messages 10¢ each. An alternative is ‘Pay as you go’ which has no monthly charge but all calls cost 30¢ per minute and texts cost 10¢ each. I typically make 100 minutes of calls and 60 text messages each month. Which would be the better contract for me and by how much?

the monthly contract seems pretty good

Write y=2x^2+24x+47 in vertex form. Also please explain/write the steps thanks.
Answers
Answer:
y=(2x^2+24x)+25
y=2x(x^2+12x)+25
y=2x(x^2+12x+36)+25-2x(36)
Y=2x(x+6)^2+25-72
Y=2x(X+6)^2-47
Step-by-step explanation:
sorry it was late
Answer: y=2(x+6)²-5
Step-by-step explanation: First you find the coefficient of x^2, which is 2, then take out 2 as a factor, 24/2 which will equal to 12. After that do 47 divided by 2 if you calculate that it will equal to 23.5. y=2(x²-12+23.5) y =2(x²-12x+23.5)
Next Step: Figure out the coefficient of x. To make it easier,look what is in front of x as you can see it is 12. Then you divide 12/2 which is 6. Then square 6, which is 36. Then you add and subtract 36. To write the first three terms as a square, you do ( x+6)^2. Then do -36 + 23.5 if you calculate that it will get you wil get -12.5 . Now that you have calculated that distribute 2, then do 2 times -12.5 which is -12.5. This is how it shoud look like y=2(x+6)² -12.5.

if f(x)=7(x-1)+8, what is the value of f(1)
Answers
Answer:
8
Step-by-step explanation:
f(1)=7(1-1)+8
f(1)=7(0)+8
f(1)=0+8
f(1)=8
The value of f(1) if f(x)=7(x-1)+8 is 8
From the question,
The given function is f(x)=7(x-1)+8
We are to determine the value of f(1) if f(x)=7(x-1)+8
To do this, we will put the value x =1 into the function
That is,
f(x)=7(x-1)+8 becomes
f(1)=7(1-1)+8
The, we get
f(1) = 7(0) + 8
f(1) = 7×0 + 8
f(1) = 0 + 8
∴ f(1) = 8
Hence, the value of f(1) if f(x)=7(x-1)+8 is 8

What is two hundred sixty-five thousandths in standard form?
Answers
Answer:
10^-1*2.65
Step-by-step explanation:
two hundred sixty-five thousandths= 0.265
We need a number between 1 and 10, to do the multiplication in standard form, so 0.265 turns into 2.65.
Because 2.65 becomes, smaller we use a negative power. We only move the decimal place once to the left, so we would multiply 2.65 by 10^1.
10^-1*2.65=0.265
The standard form of two hundred sixty-five thousandths is 265 × 10⁻³.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given that,
Two hundred sixty-five = 200 + 65 = 265
Now,
Thousandths mean we need to divide it by thousand
So,
⇒ 265/1000
⇒ 265/10³
By the law of indices
⇒ 265 × 10⁻³
Hence "The standard form of two hundred sixty-five thousandths is 265 × 10⁻³".

In the figure, m<7 = 100. Find the measure of <9.
Answers
As < 7 and angle < 9 are alternate interior angles, their sum will be equal .
Which means :-
[tex] < \: 7 = < \: 9[/tex]
[tex] < 9 = 100°[/tex]
Therefore , the value of <9 is 100° .
The magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.
What are parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is ∠7 = 100°.
The lines u and t are parallel to each other. The alternate interior angles are equal in magnitude. From the figure it is clear that ∠7 and ∠9 are alternate interior angles. Therefore, we can say that ∠7 = ∠9 = 100°.
Therefore, the magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.

Systematic sampling could assume a randomized start point in selecting observations, However, every other successive points usually follow a fixed order or selection process. In the scenario above, the manager sampling choice involves an ordered and fixed selection process whereby every fifth sample after the initial point is considered. Hence, resulting in predictable points, such as 6th, 11th, 16th, 21st, 26th, 31st,...and so on.

The number 4.8367, when rounded to the nearest tenth, becomes 4.8
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
if the right sided digit to the digit where we've to round off is < 5, we keep it same and make all right sided values 0, and if the right sided digit is > 5, then we make it increase by 1 and rest of the right sided digits become 0. If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
Rounding to the nearest tenth means rounding the first place to the right of the decimal point.
The given number is 4.8367
The digit on the right of the decimal point is 8. On the right of that, there is 3, which is < 5, so the first right digit on right of the decimal point, after rounding, will have no change,and rest of the numbers from the right first place of the decimal point will get trimmed off.
Thus, we get:
4.8367 → 4.8 (after rounding to the nearest tenth)
Thus, the number 4.8367, when rounded to the nearest tenth, becomes 4.8

Answers
Answer with step-by-step explanation:
If x = -1, we can re-write the equation as -5 - 8y = 29.
Step 1: Simplify both sides of the equation.
-5 - 8y = 29
-5 + (-8y) = 29
-8y - 5 = 29
Step 2: Add 5 to both sides.
-8y - 5 + 5 = 29 + 5
-8y = 34
Step 3: Divide both sides by -8.
-8y/-8 = 34/-8
y = -17/4

Write an equation in slope-intercept form that would have infinitely many solutions in a system of equations with 5x+2y=8
Answers
Answer:
y=5/2x-4
Step-by-step explanation:
got it right on my math assignment
The required equation of line in the slope-intercept form will be [tex]y=-\dfrac{5}{2}x+4[/tex].
The given equation of line is [tex]5x+2y=8[/tex].
It is required to write the equation of a line in the slope-intercept form which has infinitely many solutions in the system of equation with the given line.
The system of equations has infinitely many solutions when the equations are the same or all of their coefficients are in the same ratio.
So, the other equation could be,
[tex]k(5x+2y)=8k\\5x+2y=8[/tex]
Now, the equation in slope-intercept form can be written as,
[tex]5x+2y=8\\2y=-5x+8\\y=-\dfrac{5}{2}x+4[/tex]
where the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is 4.
Therefore, the required equation of line in the slope-intercept form will be [tex]y=-\dfrac{5}{2}x+4[/tex].
