Answer:

Option C is correct.

(1, 4)

Step-by-step explanation:

A system of equation is given :

2x + 3y =12                 .....[1]

4x + 2y =10                 .....[2]

Multiply equation [1] by 2 both sides we get;

2(2x+3y) = 2(12)

Using distributive property i,e a \cdot(b+c) = a\cdot b+ a\cdot c

4x + 6y = 24                           .....[3]

Subtract equation [2] from [3] to eliminate x we get;

4x + 6y - 4x - 2y= 24 - 10

Combine like terms;

4y = 14

Divide both sides by 4 we get;

y = 3.5

Substitute the value of y in equation [1] we have;

2x + 3(3.5) =12

2x + 10.5 = 12

or

2x = 12 -10.5

2x = 1.5

Divide both sides by 2 we get;

x = 0.75

Solution = (0.75 , 3.5)

Best estimate solution =  (1, 4)

Therefore, the best estimate solution of the given system of equation is, (1, 4)

Write the inverse of the function f(x) = 5x +3 ?
Ilia_Sergeevich [38]

Answer: f(x^-1) = x/5 - 3/5

Step-by-step explanation:

1. Replace f(x) with y

2. Swap the positions of x and y to make x = 5y + 3

3. Solve for y by subtracting 3 from both sides and dividing each side by 5

Thirty seven divided by nine
Sunny_sXe [5.5K]

Answer:

4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))

Step-by-step explanation:

To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.

To solve it through long division,

9 can go into 3 zero times

9 can go into 37 four times though

9*4 is 36

So subtract 36 from 37, leaving 1.

9 can go into 1 zero times.

Add a zero behind the one and 9 can go into 10 once.

The pattern continues forever, making the answer 4.1(with the one repeating)

or 4.11 (rounded to the hundredth place)

If you need anymore clarification I can certaintly help.

Twice the sum of consecutive numbers n and n+1 is 510. What is the smaller number and the larger number?
Paha777 [63]

Answer:

n is smaller, n + 1 is larger

Step-by-step explanation:

First, make the equation.

2(n + n+1) = 510

Then, simplify.

2(2n + 1) = 510

Distribute.

4n + 2 = 510

Solve.

n = 127

The smaller number is n (127) and the larger number is n + 1 (128).
