Answer:

[tex]y=2x+7[/tex]

Step-by-step explanation:

Given the equation

[tex]y=-\frac{1}{2}x[/tex]

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

so the slope of the line is -1/2

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

the slope of the perpendicular line will be: 2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2, 3) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 2 and the point (-2, 3)

[tex]y-3=2\left(x-\left(-2\right)\right)[/tex]

[tex]y-3=2\left(x+2\right)[/tex]

Add 3 to both sides

[tex]y-3+3=2\left(x+2\right)+3[/tex]

[tex]y=2x+7[/tex]

Answer:

10

is that exponent or multiplication? if exponent: 64 if multiply: 12

3.5

Does that mean divide or 17 percent of 3? if divide: 5.66 if percent: 0.51

2*5 = 10

4**3 = 64

7/2 = 3.5

17 % 3 = 2

In python,

* means multiplication

** means exponential

/ means division

% means remainder

Answer:

The best estimate is -2.64

Step-by-step explanation:

To get the estimate value we are rounding all values to the nearest hundredth

You use BOMDAS/PEMDAS to do this expression

(34/8 - 16/3) - 14/9

= 4.25 - 5.33 - 14/9

= 4.25 - 5.33 - 1.56

= -1.08 - 1.56

= -2.64

Answer:

6

Step-by-step explanation:

You must multiply both sides by a common multiple of all denominators. Usually, the least common multiple, LCM, is used since it is the smallest common multiple and makes calculations easier.

The LCM of 2, 3, and 6 is 6.

Answer:

Write this:

y= -3x + 1

Step-by-step explanation:

Solve the equation:

6x -2y = 32

Subtract 6x from both sides

-2y = -6x +32

divide by negative to on both sides

y = -3x -16

ANSWER:

y = -3x (any number ,negative or positive, except 16)

The slope of the line will be 3.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The equation of parallel line is,

⇒ 6x - 2y = 32

Now,

The slope of two parallel lines are always same.

So, We find the slope of the parallel line.

Since, The standard form of equation line is,

⇒ y = mx + c

Where, m is slope of the line.

So, We can change the equation of parallel line in the standard form.

The equation of parallel line is,

⇒ 6x - 2y = 32

Add 2y both side,

⇒ 6x - 2y + 2y = 32 + 2y

⇒ 6x = 32 + 2y

Subtract 32 both side,

⇒ 6x - 32 = 2y

⇒ 2y = 6x - 32

Divide by 2, we get;

⇒ y = 3x - 16

Compare with y = mx + c, we get;

The slope of the line (m) = 3

Thus, The slope of the line will be 3.

Answer:

Step-by-step explanation:

.25 mile in 2 mins

.25(5) miles in 10 min

1.25 mins in 10 mins

There is 5-2 mins in 10 mins. So times by the 5.

Answer:

Its 1.25

Step-by-step explanation:

Answer:

As the ratio is 5:3, it totals 8 parts. I would do 480 divided by 8 to get the number of pages per part, then multiply that number into the ratio.

480 / 8 = 60

The value of each part being 60 put into the ratio 5:3 = 60x5 : 60x3

Which gives your answer.

Answer:

600 centimeters. 1 meter is equal to 100 centimeters

Answer:

side = 14 cm

Step-by-step explanation:

Let 'x' be the side of the square.

Perimeter = 4 * side

                = 4*x

                = 4x

4x = 56

Solution:

4x = 56

Divide both sides by 4

x = 56/4

x = 14 cm

Answer:

k > 100

Step-by-step explanation:

y= x²+20x+k

if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots

discriminant is

b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400

k > 100 is the solution
