Finding angles in measures using triangles

Answer:

2 and - 1

Step-by-step explanation:

Calculate the gradients using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, -3) and (x₂, y₂ ) = (3, 7) ← 2 points on line A

[tex]m_{A}[/tex] = [tex]\frac{7+3}{3+2}[/tex] = [tex]\frac{10}{5}[/tex] = 2

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (7, - 2) ← 2 points on line B

[tex]m_{B}[/tex] = [tex]\frac{-2-7}{7+2}[/tex] = [tex]\frac{-9}{9}[/tex] = - 1

========================================================

Explanation:

The two points on this line are (-1,5) and (0,1)

Let's use the slope formula

m = (y2-y1)/(x2-x1)

m = (1-5)/(0-(-1))

m = (1-5)/(0+1)

m = -4/1

m = -4

The slope is m = -4

If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

With m = -4 and b = 1, we go from y = mx+b to y = -4x+1

Answer:

Step-by-step explanation:

You need to set up a proportion.

(21 - 15) / 21  = 4/(x + 4)

6 / 21 = 4/(x + 4)

2/7 = 4/(x + 4)

2(x + 4) = 7*4

2x + 8 = 28

2x + 8-8= 28 - 8

2x = 20

x = 20/2

x = 10

Answer:

628

Step-by-step explanation:

Well, if you x's are multiplication signs, then the answer is 628 because

6x100=600, 1x10=10, 7x1=7,  9x1=9, 2x1=2 and then add them all up:

600+10+7+9+2=628

Answer:

628

Step-by-step explanation:

6x100= 600

1x10= 10

7x1= 7

9x1= 9

2x1= 2

600 + 10 = 610

7 + 9 = 16

16 + 2 = 18

610 + 18 = 628

Answer:

f(-12) = -15

Step-by-step explanation:

f (-12)

we put -12 in place of x

-12 - 3 = -15

so, f(-12) = -15

Answer

I think 55 times

Step-by-step explanation:

13,200/1,200 = 11

5/1200 =  x/13,200

so if 1,200*11=13, 200 then 5*11= 55.

The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:

Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.

Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.

Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:

[tex]=\dfrac{13200}{1200}\times 5[/tex]

= 55 times

Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:

[tex]=\dfrac{55}{5}\times 1[/tex]

= 11 days

There are 4 big fish for every 5 small fish.

The ratio of two numbers a and b is given by a divided by b and represented by a/b or a:b. While the proportion is the relation between two ratios of a/b and c/d is represented by a:b::c:d or a/b=c/d.

Given that, there are 8 big fish for every 10 small fish, we need to find how many are there for 4 big fish for every.

We will solve this by using proportion,

Let the number of small fishes be x

Therefore,

8 / 10 = 4 / x

x = 5

Hence, there are 5 small fish for every 4 big fishes.

Answer:

[tex]y=6x-19[/tex] is the function which best

represented by this graph.

The graph is also attached.

Step-by-step explanation:

As the point-slope form is

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

where m is the slope

Given

m = 6 and the point (4, 5)

substituting the values in the point-slope form

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

[tex]y - 5 = 6 (x - 4)[/tex]

[tex]y - 5 = 6x-24[/tex]

[tex]y=6x+5-24[/tex]

[tex]y=6x-19[/tex]

Therefore, [tex]y=6x-19[/tex] is the function which best
