What is the slope of the line represented by the equation 3x + 4y
12?

Answer:

(B) 60°

Step-by-step explanation:

The total sum of angles in a triangle is 180°. Since you already know the first 2 angles, you can find the last angle C.

C = 180° - 50° - 70°

  = 60°

Answer:

(0.5, 1)

Step-by-step explanation:

The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

[tex](\frac{-1+2}{2},\frac{5-3}{2})=(\frac{1}{2} ,\frac{2}{2} )=(0.5,1)[/tex]

The answer is thus (0.5, 1).

Answer:

x = 24yrs and y = 27yrs

Step-by-step explanation:

Let the age of one of the teachers be x

Let the age of the other teacher be y

From the second sentence;

x + y = 51 ----------(1)

From the first sentence;

x/y = 8/9 ------------(2)

Making y the subject of formula in equation (1) as follows;

y = 51 -x -------------(3)

Substitute (3) into (2) as follows;

x/51- x = 8/9

Cross multiply as follows:

9*x = 8(51- x)

9x = 408 - 8x

Collecting like terms;

9x + 8x = 408

17x = 408

Divide both sides by 17;

x = 24 yrs

Substitute x = 24 into equation (3) as follows;

y = 51 - 24

y = 27 yrs

This is a right angle triangle.

So, by Pythagoras theorem,

√(32^2+20^2) = x

or √(1024+400) = x

or √1424 = x

or 37.74 = x

Step-by-step explanation:

4a - No

4b - Yes

4c - Yes

4d - No

Answer:

4a. yes cuz 0.2 is the same as 1/5 just in a fraction form

4b. yes cuz your counting by 1's so 0.1 0.2 etc

4c. yes cuz 0.7 is 7/10

4d. no cuz your counting by 1's so 0.1 0.2 0.3 etc

Answer:

-1.973

Step-by-step explanation:

Given the data :

Age 36 39 48 53 58

Bone Density 358 351 330 325 314

Equation of regression line is in the form:

yˆ=b0+b1x

Where y = predicted variable ;

b0 = intercept ; b1 = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = -1.97316X + 427.94399

From the equation ;

The slope or gradient (b1) = - 1.97316

Hence, estimated slope to 3 decimal places is : - 1.973

Answer:

Because the law of contract has to do with private law relation.

Step-by-step explanation:

Given that law of contract has to deal with Private laws involving parties to the contract, but not in any way affecting or involving the state or society. The law of contract has seen so little constitutional transformation. For example law of the contract between manufacturers of cars and consumers or buyers.

This is evident in the fact that people's perception and the reality is that the outcomes of the successful delivery or breach of the law of contract have no direct implication on the other people in the society such as individual rights.

Answer:

X and Y are independent

Step-by-step explanation:

attached below is the detailed solution

X and Y are independent

f(x,y) = fx(x) fy (y) = 1

Like you said, we need to use substitution to solve for y.

[tex]x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10[/tex]

Now that we've solved for y, we can plug in the number we got into one of the original equations. (You can choose either equation, but I will use the first one.)

[tex]x + 10 = 11\\\\x = 1[/tex]

Now we have the solution of this system.

[tex](1, 10)[/tex]

Answer:

Answer is 6 and 2/3. That’s it

Step-by-step explanation:

The length of JN of the second triangle is  [tex]6\frac{2}{3}[/tex].

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.

Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

As the two triangles BTL and PJN are similar because the corresponding two angles are given equal in the question.

Thus, the ratios of the side are equal.

[tex]\frac{BT}{JP} = \frac{LT}{JN}[/tex]

[tex]\frac{6}{8} =\frac{5}{JN}[/tex]

[tex]JN =\frac{20}{3}[/tex]

[tex]JN= 6\frac{2}{3}[/tex]

Therefore, the length JN of the triangle comes out to be [tex]6\frac{2}{3}[/tex].

Step-by-step explanation:

Answer:

x = -14/5 or -2.8

Step-by-step explanation:

6 - 5x = 20

Subtract 6 from both sides.

- 5x = 14

Divide both sides by - 5

x = -14/5 or -2.8

Step-by-step explanation:

Miguel will circle 10 counters because 5/8 * 16 = 10.

Answer:

A. 10 is the correct answer.

Step-by-step explanation:

The equation is 5/8 x 16.

Here, there are 16 counters. This is also known as 2 rounds of 8, which is the denominator in our fraction. Since 8 is 1/2 times 16, 5 x 2, or 10, is the correct answer.
