Basically move the decimal point to the left once if it’s 10% with decimals.

Answer:

430,000

Step-by-step explanation:

Answer:

x = 47

Step-by-step explanation:

Because the lines are parallel, we know that some angles are the same, see the images attached. That means that A and B in the image are the same angles. So we know that angle A totals to 78 degrees. And the angle outside the triangle is 35. So the angle inside the triangle is

78 - 35 = 43.

The interior angles of a triangle add up to 180. We know that one angle is 43 and another angle is 90 because of the indicating square angle marker. That means that

43 + 90 + x = 180.

Then we can simplify the equation:

133 + x = 180⇒

x = 180 - 133⇒

x = 47

Answer:

y = 6x - 3

Step-by-step explanation:

y = mx + B

3 = 6(1) + B

3 = 6 + b

3 - 6 = b

-3 = b

b = -3

3 = 6(1) - 3

3 = 3

y = 6x - 3

Answer: To find a distance, we need to multiply speed by time.

Answer:

(y+13)=5(x+2)

Step-by-step explanation:

Apply the formula (y-y1)=m(x-x1) to the given point and slope intercept form equation.

Answer:

the answer is x=-1

Step-by-step explanation:

The required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question below as:

5x + 1.2 = −3.8

We have to determine the solution to the given equation 5x + 1.2 = −3.8

⇒ 5x + 1.2 = −3.8

Rearrange the terms of non-variable in the above equation,

⇒ 5x =  - 3.8 - 1.2

Apply the addition operation,

⇒ 5x = -5

Divided by 5 both sides of the above equation,

⇒ x = -5 / 5

Apply the division operation,

⇒ x = - 1

Therefore, the required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

Answer:

3x and 2 are both variables

Step-by-step explanation:

In mathematics, a variable is a symbol which works as a placeholder for expression or quantities that may vary or change; is often used to represent the argument of a function or an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.

Have a great day! :D

Step-by-step explanation:

the slope = (4-0)/(-1-0) = 4/(-1) = -4

the equation : y = -4x

m = (Y2 - Y1)/(X2 - X1)

m = (0 - 4)/(0 - (-1))

m = -4/(0 + 1)

m = -4/1 = -4

Answer:

5

Step-by-step explanation:

(y2-y1)/(x2-x1), when you plug the numbers into the formula, you should get 5

Answer:

  x = ±3√2i

Step-by-step explanation:

Add -18 to both sides of the equation:

  x^2 = -18

Take the square root of both sides:

  x = ±√(-18)

Remember that 18=9·2 = (3^2)·2 and √-1 = i. Simplify.

  x = ±(√(3^2))·(√2)·(√-1)

  x = ±3√2i

Answer:

1

Step-by-step explanation:

let x = smallest

let x+2 = middle

let x+4 = largest

x + x + 4 = 6(x +2) - 12

2x + 4 = 6x + 12 - 12

2x + 4 = 6x

4 = 4x

x = 1

numbers are 1, 3, 5

check:

is 1 + 5 equal to 6(3) - 12

6 = 18 - 12

6 = 6

Step-by-step explanation:you just -5

Answer:

±5

Step-by-step explanation:

Given equation ,

=> x² - 25 = 0

=> x² - 5² = 0

=> ( x +5)(x-5) = 0

=> x = ±5

Answer:

x = -5 or 5

Step-by-step explanation:

→ Factor the quadratic

( x + 5 ) ( x - 5 )

→ Equate each bracket to 0

x + 5 = 0 and x - 5 = 0

→ Solve each for x

x = -5 or 5

Answer:

[tex]\boxed{y = -5,5x - 52}[/tex]

Step-by-step explanation:

Equation of a straight line: y = kx + b

Points: (-10,3) and (-8,-8)

Сompose the system of equations:

[tex]\displaystyle \left \{ {{3=-10k + b} \atop {-8=-8k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 3 + 10k} \atop {b=8k - 8}} \right \Longrightarrow 3 + 10k = 8k - 8[/tex]
