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

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°.

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

what is the expression in from 4^n
Answer: 14n or (14×n)
Step-by-step explanation:
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

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

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.

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].

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.
