One number is 14 more than another number. Their sum is 58. Find the numbers.
Numbers are 36, 22
What is an equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in mathematics when you do not know the exact number in a calculation.
Given
One number is 14 more than another and their sum is 58.
Let one number be x
Another number will be x + 14
Rewriting the equation in mathematical form
⇒ [tex]n+ (n+4) =58[/tex]
⇒ [tex]2n +14 =58[/tex]
⇒ [tex]2n = 58-14[/tex]
⇒ [tex]2n=44[/tex]
⇒ [tex]n= \frac{44}{2}[/tex]
⇒ [tex]n=22[/tex]
⇒ [tex]n+14=22+14=36[/tex]
Hence, numbers are 36, 22

Answer: Systematic sampling
Step-by-step explanation: Systematic sampling usually takes an ordered technique or process in dealing with samples. 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.

given that 5x - 8y = 29 find y when x = -1 give your answer as an improper fraction
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

Round to the nearest tenth.
4.8367
Answer:
Number = 4.8367
Rounded to the nearest tenth means, rounded to the number after the decimal point.
We will have to round down because the hundredth is less than 5
So, we get,
4.8367 becomes, 4.8
Therefore 4.8367 rounded to the nearest tenth = 4.8

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

if f(x)=7(x-1)+8, what is the value of f(1)
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

Write an equation in slope-intercept form that would have infinitely many solutions in a system of equations with 5x+2y=8
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].

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?

Write y=2x^2+24x+47 in vertex form. Also please explain/write the steps thanks.
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.

In the figure, m<7 = 100. Find the measure of <9.
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°.
