Heeeeeelp pleaseeeeeee

Answer:

x = 12

Step-by-step explanation:

DE + EF = DF

2x - 1 + 5x - 13 = 70

7x - 14 = 70

7x = 70 + 14

    = 84

x = 84 ÷ 7

x = 12

Answer: x=12

Step-by-step explanation:

2x-1+5x-13=70

Combine like terms

7x-14=70

Add 14 to both sides

7x=84

Divide both sides by 7

X=12

Answer:

15°C

Step-by-step explanation:

Find the difference by subtracting -4.8 from 10.2

10.2 - (-4.8)

Subtracting a negative number changes to adding a positive number:

10.2 + 4.8

= 15

So, the difference in temperature between the two cities is 15°C

Answer:

AB is undefined, CD is y = -5

Step-by-step explanation:

Find both of the line's slopes. You can use the formula for slope to calculate this answer because you know two points on the line for both lines (Look below). If you plug in the points for AB, you would have ( -2 - 7)/0, which would be undefined, because anything divided by 0 is undefined. Since the slope for AB is undefined, it is undefined. Next, we have CD. If you plug in the points for CD, you would get (-5 - (-5))/(6 - 3), which would be 0/3, which is 0. This means that the slope is 0. Next, we have to plug in the points for CD into the formula for equation of the line (Look Below), which would be y - (-5) = 0 * (x - 6), which simplifies to y + 5 = 0, which is y = -5.

Formula for Slope:

[tex]\frac{y1 - y2}{x1 - x2}[/tex]

Usable with 2 points of the line given ((x1, y1) and (x2, y2))

Formula for Equation of the Line:

[tex]y - y1 = slope * (x - x1)[/tex]

Usable with the slope and a point given ((x1, y1))

Answer: AB is undefined (AB is not a relationship, slope is undefined (Vertical Line)) and CD is y = -5 (Horizontal Line)

Answer:

c) 160,000

Step-by-step explanation:

Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:

120,000 x 1.2 = 144,000.

Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:

1 - .1 = .9

144,000 / .9 = 160,000

1 1/2 cups of flour = 12/8 cups of flour

2 2/3 cups of oatmeal = 2 2/3 cups of oatmeal

1 cup sugar = 3/3 or 8/8 cups of sugar

1/2 cup of brown sugar = 4/8 cups of brown sugar

Answer:

See below

Step-by-step explanation:

There are two ways to graph an equation.

1st Way:

We can use a graphing calculator. (See the attached file)

2nd Way:

We can take the values of x as 0, 1 , 2 (Or anything).

Then, We have to put the values of x in the equation to get the value of y accordingly.

According to these values, Plot the graph.

Also,

Slope = 5 / 6

y-intercept = 1

Answer:

A is the answer

Step-by-step explanation:

Becuase if it has the same radius and the same height. then they will both be equal.

Answer:

15 feet

Step-by-step explanation:

Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot

Using similar triangles

= Let the height of the flagpole be represented as h.

h/35 =5/12

We cross Multiply

35 x 5 = 12h

12h = 175

h = 175/12

h = 14.583333333 feet

Approximately to the nearest foot is

h = 15 feet

Answer:

[tex]F = 1.8C +32[/tex]

[tex]F = 86^{\circ}F[/tex]

Step-by-step explanation:

Represent Celsius with C and Fahrenheit with F.

So, we have:

[tex](C_1,F_1) = (100,212)[/tex]

[tex](C_2,F_2) = (0,32)[/tex]

Solving (a): Represent as a linear equation

First, we calculate the slope:

[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]

This gives:

[tex]m = \frac{32 - 212}{0 - 100}[/tex]

[tex]m = \frac{-180}{- 100}[/tex]

[tex]m = 1.8[/tex]

The linear equation is then calculated using:

[tex]F - F_1 = m(C -C_1)[/tex]

Where

[tex](C_1,F_1) = (100,212)[/tex]

[tex]m = 1.8[/tex]

[tex]F - 212 = 1.8(C -100)[/tex]

[tex]F - 212 = 1.8C -180[/tex]

Make F the subject

[tex]F = 1.8C -180+212[/tex]

[tex]F = 1.8C +32[/tex]

Solving (b): The value of F when C = 30

Substitute 30 for C in [tex]F = 1.8C +32[/tex]

[tex]F = 1.8 * 30 + 32[/tex]

[tex]F = 54 + 32[/tex]

[tex]F = 86[/tex]

Answer:

person above me is wrong

Answer:

x= -1

Step-by-step explanation:

Answer:

1 ( 12-3m ) - 5m ( 11-4m+25)

1 ( 9m ) - 5m ( 32m )

9m -5m ( 32m )

4m ( 32m )

32×4 = 128 m

128 m

Answer:

Without an equivalence given (i.e. an equals sign somewhere in the expression), we have no way of solving for m.

We can however simplify it:

m²(2 - 3m) - 6m(1 - 4m + 5m²)

= 2m² + 3m³- 6m + 24m² - 30m⁴

= 26m² + 3m³ - 6m - 30m⁴

= m(-30m³ + 3m² + 26m - 6)
