What is the slope of a line that is perpendicular to the line y=2x+3?

Answer:

fe

Step-by-step explanation:

Answer:

0.09x +10 is the first choice

0.07x +16 is the second choice (set the two data plans equal to each other)

0.09x +10 = 0.07x +16  (subtract 0.07x from both sides)

0.02x +10 = 16 (subtract 10 from both sides)

0.02x = 6  (divide both sides b 0.02 to isolate x)

x= 300 MB of data (the answer)

Answer:

x=-3

Step-by-step explanation:

If x=-3, then

x³+x²-2x+12=-27+9+6+12=-27+27=0

If this is true, then x+3 is a factor. So:

x³+x²-2x+12/x+3=x²-2x+4

So the factors of x³+x²-2x+12 are:

(x+3)(x²-2x+4)

((x²-2x+4) has no real roots)........

Answer:

Answer of this equation is (x-2)^2/ (X+3)^2

Step-by-step explanation:

x^2-4/X+3 × x-2/ x^2+5x+6

(X+2)(x-2) / X+3 × x-2/ x^2+(2+3)X+6

(X+2)(x-2)/X+3 × x-2/(X+2)(X+3)

(x-2)(x-2)/(X+3)(X+3)

(x-2)^2/(X+3)^2

Answer:

b) The average speed at which he travelled for the whole journey

Step-by-step explanation:

If he had travel 200- km/h and had broke down by which was at 10:30 a.m  you would have to subtract 200 km/h to 10:30  your answer would be 189.7 when they back on the road also the speed slowed down a bit about 50 km/h so you would add 50 km/h to 20 mins you would get 70km/h they were traveling by, then you add all of the numbers up by 100 you would get 640 so your answer would be 640

Answer:

The image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

Step-by-step explanation:

We know that when a point, let say P(x, y), is reflected across the y-axis, the sign of x-coordinate is reversed but y-coordinate remains the same.

In other words, the rule is:

P(x, y) → P'(-x, y)

Here, P'(x, y) is the image of the original point P(x, y) after the reflection across the y-axis.

Considering the point

Let us reflect the point A(2, 3) across the y-axis.

We know the rule:

P(x, y) → P'(-x, y)

so

A(2, 3) → A'(-2, 3)

Thus, the image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

x − 3 = 6 − 2 x = − 8 √ x = 3

Step-by-step explanation:

Select which do not represent proportionality

Proportionality exists when a unit rate can be calculated.

For instance:

- If 2 litres of gas is $2, then the unit rate is $1 per litre

- If an employee is paid $100 for 5 days, then the unit rate is $20 daily

- If 5 movie tickets cost $50, then the unit rate is $10 per movie

The above scenario are used to describe options (2 - 4) because they can be expressed in unit rates.

However, this is not the same for age and height because age is not a function of height and height is not a function of age. In other words, they can not be expressed in proportions.

So, option (a) is not a situation of proportionality.

Answer:

a. Geometric

b. 20, 10 and 5

c. Tn = 20(0.5)^n-1

d. 0.00004 ft

Step-by-step explanation:

a. The sequence is geometric

The reason for this is that we will be multiplying each term by a particular value

If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number

b. 1st term is

20

second term

1/2 * 20 = 10

Third term

1/2 * 10 = 5

c. Explicit formula

Mathematically, that will be;

Tn = ar^n-1

Where r is 1/2 or 0.5

Tn = a(0.5)^n-1

where Tn is the present term and n is the present number of the term

d. 20th term

T20 = 20 * 0.5^19

T20 = 0.00004 ft

The two variables in this problem are dollars and hours

Melissa charges $1.25 per hour to pet-sit.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The table and the given points on the coordinate plane provide information about the relationship between the number of hours of

pet-sitting (x) and the amount of money earned (y) by Melissa, who charges a fixed rate of $1.25 per hour for pet-sitting.

The equation of the line passing through the points (1, 1.25) and (4, 5) can be found by using the slope-intercept form:

y - y_1 = m (x - x_1),

where m is the slope and (x_1, y_1) is a point on the line.

Using the two given points, we have:

m = (y_2 - y_1)/(x_2 - x_1)

= (5 - 1.25)/(4 - 1)

= 1.25

y - 1.25 = 1.25 (x - 1)

y = 1.25x - 0.75

This means that for each additional hour of pet-sitting, Melissa earns an additional $1.25.

Therefore,

The two variables in this problem are dollars and hours

Melissa charges $1.25 per hour to pet-sit.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Though i am unable to attach an image of the question here. However, i will do my best to explain quite well.

The densities of the liquids are;

A - 13.6 g/ml

B- 0.8 g/ml

C- 1.0 g/ml

The most dense liquids will be found at the bottom while the least dense liquid is topmost liquid. This implies that A will be found at the bottom followed by C and finally B.

Answer:

Option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

Determining the difference of the fractions

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

[tex]\frac{1}{5}-\frac{3}{4}=\frac{4}{20}-\frac{15}{20}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

          [tex]=\frac{4-15}{20}[/tex]

Add the number: 4-15 = -11

           [tex]=\frac{-11}{20}[/tex]

Apply the fraction rule:  [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

            [tex]=-\frac{11}{20}[/tex]

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.

Therefore, option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Answer:

35 cm

Step-by-step explanation:

Diameter of small pizza = 16

Let Diameter of large pizza = x

Diameter of small pizza = 2/5(x) + 2

2/5(x) + 2 = 16

(2x / 5) + 2 = 16

2x / 5 = 16 - 2

2x / 5 = 14

multiply both sides by 5

2x = 14 * 5

2x = 70

Divide both sides by 2

x = 70/2

x = 35

Diameter of large pizza = 35 mm

a. The equation that both services would cost the same is

0.25x + 5 = 0.35x + 2.

b. The weight of Mr. Molinary's package is 30 ounces.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, AAA Packages Plus sends packages overnight for $5 plus $0.25 per ounce.

United Packages charges $2 plus $0.35 per ounce.

Assuming the no. of ounces to be x.

∴ 0.25x + 5 = 0.35x + 2.

0.25x - 0.35x = 2 - 5.

- 0.1x = - 3.

x = 3/0.1

x = 30 ounces.
