Given: 5n-42=12n prove: n=-6

Answers

Answer:

n=-6

Step-by-step explanation:

5n-42=12n

5n=12n+24

5n-12n=42

-7n=42

divide each side by -7

n does =-6

The required proof for n = -6 is given in the solution.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given equation is,

5n - 42 = 12n

Taking alike terms together we get,

5n - 12n = 42

Solving we get,

-7n = 42

Dividing both the side by -7 we get,

-7n/-7 = 42/-7

Solving we get,

n = -6

Hence we get the required proof.

Thus, the required proof for n = -6 is given in the solution.

Line s has an equation of y=-1/7x-10. Parallel to line s is line t, which passes through the point (9,-2). What is the equation of line t?

Answers

Answer:

y = -1/7x + 5/7

Step-by-step explanation:

The slope of a parallel line is the same as the original.

Find the new y-intercept.

y = -1/7x + b

-2 = -1/7(9) + b

-2 = -9/7 + b

5/7 = b

y = -1/7x + 5/7

when 24 is subtracted from the square of a number the result is five times a number what is the negative solution

Answers

Step-by-step explanation:

let the unknown be x

24 - x^2 = 5x

-x^2 - 5x + 24 = 0

(x - 3)(x + 8) =0

x = 3 (or) x = -8

if u wanna check

if you wanna check

24 - (-8)^2 =5(-8)

24 - 64 = -40

-40 = -40

since you ask for negative solution

x= -8 is a NUMBER

the solution is 5times of a NUMBER = -8 × 5 = -40

hope I got it right^^,good luck!

Answers

Answer:

x = -5/21

Step-by-step explanation:

Step 1: Write equation

2(12x - 1) = (21x - 49)/7

Step 2: Solve for x

Multiply both sides by 7: 14(12x - 1) = 21x - 49Distribute 14: 168x - 14 = 21x - 49Subtract 21x on both sides: 147x - 14 = -49Add 14 to both sides: 147x = -35Divide both sides by 147: x = -5/21

Given triangle ABC with coordinates A(−2, 7), B(−2, 4), and C(−4, 3), and its image A′B′C′ with A′(2, 3), B′(−1, 3), and C′(−2, 1), find the line of reflection.

The line of reflection is at y =

Answers

Answer:

y = x + 5

Step-by-step explanation:

given an obtuse scalene triangle (∆ABC) with vertices A(-2,7), B(-2,4), and C(-4,3) (representing the preimage of the reflection). And congruent triangle (∆A'B'C') with vertices A'(2,3), B'(-1,3), and C'(-2,1) (representing the image of the reflection / triangle after the reflection).

The easiest way to look at this is by taking the inverse of each point on the preimage (swapping y and x coordinates) and the adding 5 to the y and subtracting 5 from the x to get the image.

You can test this, and you will see that this will match with vertices of the image.

16.827 to the nearest whole.

Answers

Answer:

Step-by-step explanation:

We want to round 16.827 to the nearest whole number.

When we round a number to the nearest place value, we always look at the digit in the place value to its right.

Here, we're technically rounding to the nearest ones place, so look at the tenths place. It's an 8. Remember that we round up if the digit is 5-9 and round down if the digit is 0-4.

Since it's 8, we round up. Thus, 16.827 rounds up to 17.
