Answer: The correct option is

$(A)~~x+y=90,~~x-y=8.$

Step-by-step explanation: Given that one of the two complementary angles is 8 degrees less than the other.

We are to select the correct system of equations represents the given word problem.

Let x and y represents the two complementary angles where y is less than x.

Since one angle is 8 degrees less than the other and y is less than x, so we have

$x-y=8.$

We know that the sum of two complementary angles is 90 degrees, so we get

$x+y=90.$

Thus, the required system of equations representing the given word problem will be

$x+y=90,\\\\x-y=8.$

Option (A) is CORRECT.

I think it is the middle one becuase complimentary angles add up to 90 degrees and if one is 8 less than the other it would be proved like that.

What is this problem -12=4(x-7)-8x

Fofino [41]

-12=4(x-7)-8x

One solution was found :

x = -4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-12-(4*(x-7)-8*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

-12 - (4 • (x - 7) - 8x) = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

4x + 16 = 4 • (x + 4)

Equation at the end of step 3 :

4 • (x + 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 4 = 0

Hope this helps you, Have a nice day.

So what you do,is you add them together to get 13/10 but then you can also simplify it but you can keep the answer to 13/10

Help! ASAP!!!

Answer:

7.2 units

Step-by-step explanation:

Coordinates of city A = (0, 0)

Coordinates of city B = (6, 4)

Use the distance formula to find the distance between the two cities as follows:

$AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(0, 0) = (x_1, y_1)$

$B(6, 4) = (x_2, y_2)$

Plug in the values into the formula

$AB = \sqrt{(6 - 0)^2 + (4 - 0)^2}$

$AB = \sqrt{(6)^2 + (4)^2}$

$AB = \sqrt{36 + 16} = \sqrt{52}$

$AB = 7.2$ (nearest tenth)

WILL GIVE BRAINLIEST AND 20 POINTS! Which function is the inverse of f(x) = -5x -4?

inn [45]

Answer:

-1/5x -4/5 = y

Step-by-step explanation:

f(x) = -5x -4

y = -5x-4

Switch x and y

x = -5y -4

Solve for y

Add 4

x+4 = -5y

Divide by -5

-1/5x - 4/5 = -5y/-5

-1/5x -4/5 = y
