Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.
Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).
Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?
Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.
Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.
Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.
Answers
Answer:
see below
Step-by-step explanation:
given: size of television is height = 37 in, length = 71 in.
A. using Pythagorean theorem:
parts given are legs which is the sides
looking for the hypotenuse.
B. formula:
a² + b² = c² or H² + L² = D²
where H = height = 37
L = length = 71
D = diagonal (which is req'd)
C. D² = 37² + 71²
D = [tex]\sqrt{1369+ 5041}[/tex]
D = [tex]\sqrt{6410}[/tex]
D = 80 in (missing length)
D. size of television:
37 x 71 in
Diagonal is 80 in

The total length of three boards is 7/8 of a yard. The length of two of the boards are 1/4 of a yard and 3/16 of a yard. What is the length of the third board.
Answers
Answer:
7/16 of a yard
Step-by-step explanation:
Let's put the boards to the same denominator so it's easier.
Let's go with a denominator of 16
1/4= 4/16
7/8= 14/16
3/16 stays the same.
So, 4/16+3/16+x=14/16
7/16+x=14/16
x=7/16 of a yard, the length of the 3rd board.

Laura deposits $2,000 in an account that has an annual interest rate of 1.96%,
compounded monthly. How much interest will she earn at the end of 1 month?
Round to the nearest cent. *
Answers
Answer:
$3.23
Step-by-step explanation:
Given that,
Principal, P = $2,000
Rate of interest, r = 1.96%
Tie, n = 1 month = (1/12) years
The formula of compound interest is given by :
[tex]CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23[/tex]
So, the interest will she earn at the end of 1 month is $3.23
The amount she earns at the end of 1 month is 200,326cents
The formula for calculating the compound amount is given as:
A = P(1 + r/n)^ntr is the raten is the compounding timet is the timeA = 2000(1 + 0.0196/12)^(12*1/12)
A = 2000 (1+0.00163)^1
A = 2000(1.00163)
A = $2,003.26
Hence the amount she earns at the end of 1 month is 200,326cents

How to find a rational function given 2 vertical asymptotes and an X intercept?
It’s question 20 by the way
Answers
Answer:
[tex]\frac{x-4}{(x+3)(x-5)}[/tex]
Step-by-step explanation:
Since the rational function has vertical asymptotes at -3, and 5, the denominator must equal 0 when x is -3 or 5. Therefore, the denominator must be:
(x+3)(x-5)
Now, to make the x-intercept at (4, 0), the numerator must be equal to 0 when x is 4. Therefore, the numerator must be:
x-4
Therefore, that rational function is:

write the equation to solve for x 3x + 21 6x - 60 please help i was given 3x+21=6x-60 thats wrong can someone please help richard u are amazing wish i could message u u can me
Answers
Answer:
3x + 21 = 6x - 60
Step-by-step explanation:
parallel angles are equal
3x + 21 = 6x - 60
combine similar terms:
3x - 6x = -60 - 21
-3x = -81
x = 81/3
x = 27
now, plugin the value of x=27 back into the equation to get the angle:
= 3x + 21
= 3(27) + 21
= 102
= 6x - 60
= 6(27) - 60
= 102
as you noticed, both values are equal 102 = 102 because its a parallel angles
so the equation is 3x + 21 = 6x - 60

Step-by-step explanation:
Answer:
Divide both sides by a constant to simplify the equation. Thus the second option.
Step-by-step explanation:
Solve for x:
9 - 10 x = -1
Hint: | Isolate terms with x to the left hand side.
Subtract 9 from both sides:
(9 - 9) - 10 x = -9 - 1
Hint: | Look for the difference of two identical terms.
9 - 9 = 0:
-10 x = -9 - 1
Hint: | Evaluate -9 - 1.
-9 - 1 = -10:
-10 x = -10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -10 x = -10 by -10:
(-10 x)/(-10) = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
x = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
