Answer:

x=-13

Step-by-step explanation:

the line is on the x axis and cant change its x axis of -13

Answer:

x is being multiplied by 7p so to find x you need to have it alone on one side of the problem, so you could divide both sides by 7p, making it look like 2n+3pm/7p=x (simplify if needed)

Step-by-step explanation:

Answer:

m=1/0 (undefined)

equation=y2-y1/x2-x1=y-y1/x-x1

since M is undefined and M=y2-y1/x2-x1

then the equation=y-y1/x-x1=1/0

y-3/x--1=1/0

cross multiplying

0 (y-3)=1 (x+1)

=x+1

The law of sines can't only be applied to right triangles. Therefore, it's B. False.

The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all the three sides of the triangle.

The law of sines is used to solve any triangle, when we know two angles and one side or two angles and one included side. So, it can be used on non-right triangle and right triangle as the case may be.

The sine law states that the ratio of a triangle's side length to the sine of the opposite angle is the same for all three sides. When we are given a) two angles and one side, or b) two sides and a non-included angle, we use the sine rule.

2y - 4x + 6 = 0

2y = 4x - 6

y = 4x/2 - 6/2

y = 2x - 3

Answer:

[tex]y = 2x - 3[/tex]

Step-by-step explanation:

Simply make the y as the subject

[tex]2y - 4x + 6 = 0 \\ 2y - 4x = - 6 \\ 2y = - 6 + 4x \\ \frac{2y}{2} = \frac{ - 6 + 4x}{2} \\ y = - 3 + 2x \\ y = 2x - 3[/tex]

So,

The proportion which represents the 65% of 90 is:

Step-by-step explanation:

Given information:

We need to find the proportion that can be used to find

65% of 90

Let us take :

% of

So,

Hence , the proportion which represents the 65% of 90 is

Answer:

The proportion [tex]\frac{65}{100} = \frac{x}{90}[/tex]

Step-by-step explanation:

[tex]\frac{65}{100} = \frac{x}{90}[/tex]

(65)(90) = 100x

5850/100 = x = 58.5

58.5 = 65% of 90

Alternatively, you can use the more direct approach:

[tex]\frac{65}{100} (90)[/tex]

= [tex]\frac{65 * 9}{10}[/tex] = 585/10 = 58.5

The 50 ft string makes an angle of 39 degrees with the ground so the stromg and balloon form a right-angle triangle to the ground.

The height of balloon from string = 50*sin(39degrees)

= 31.47 ft

As the string is held by a person 5 ft above ground, the balloon is above ground at 31.47 + 5

= 36.47 ft.

Answer:

20

Step-by-step explanation:

I did this test is 20

60 percent of 20 is 12 dollars

The original price of a pair of jeans would be; 30 dollar.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b% Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Given that a pair of jeans is only $12 after a 60% discount.

The original price in percentage terms = 100%

After the first discount, the price is : 100- 60% = 40%

The equation can be used to represent the price;

40% x original price = $12

0.40 x p = 12

where p = original price

Divide both sides of the equation by 0.40;

p= $30

Hence, The original price of a pair of jeans would be; 30 dollar.

Answer:

x = 51°

Step-by-step explanation:

The image of the triangle is an isosceles triangle. Since it is an isosceles triangle, ∠DFE = ∠FDE.

78 + x + x = 180

=> 2x = 102

=> x = 51°

30 is the length of the hypotenuse

24 is one of the bases

a^2+b^2 = c^2

where c is the hypotenuse (longest side)

24^2 + y^2 = 30^2

576 +y^2 = 900

y^2 = 324

y= √324 = 18

y =  18

Step-by-step explanation:

1) 3 – 36i = 9a + 4bi

3 = 9a => a = 3/9 = ⅓

-36 = 4b => b = -36/4 = -9

2) a – 15i = -7 – (2b-3)i

a = -7

-15 = -(2b-3)

2b-3 = 15

2b = 18

b = 18/2= 9

Answer:

[tex]y = \frac{1}{4} x - 11[/tex]

Step-by-step explanation:

Slope- intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Slope

= 0.25

= ¼

Substitute m= ¼ into the equation:

y= ¼x +c

Given that the y-intercept is -11, c= -11.

Thus, the equation of the line is y= ¼x -11.

The logarithmic property chosen here is:

[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex], and its validity is proven below:

The logarithmic properties are up to six, but one of it that is applicable here is:

[tex]log_{a}[/tex] m - [tex]log_{a}[/tex] n = [tex]log_{a}[/tex] [tex]\frac{m}{n}[/tex]

In the above expression, both the numerator and denominator have the same base number, but different powers. So in this case, dividing a number of power m by the same number but of power n would given an answer that is the same as the number to the power of the difference between m and n.

For example: Solve;

a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3

b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5

c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2

Solutions:

a. [tex]log_{10}[/tex] 6 - [tex]log_{10}[/tex] 3 = [tex]log_{10}[/tex] [tex]\frac{6}{2}[/tex]

        = [tex]log_{10}[/tex] 2

        = 0.3010

b. [tex]log_{10}[/tex] 8 - [tex]log_{10}[/tex] 5 = [tex]log_{10}[/tex] [tex]\frac{8}{5}[/tex]

      = [tex]log_{10}[/tex] 1.6

       = 0.2041

c. [tex]log_{b}[/tex] 6 - [tex]log_{b}[/tex] 2 = [tex]log_{b}[/tex] [tex]\frac{6}{2}[/tex]

        = [tex]log_{b}[/tex] 3
