Step-by-step explanation:

which equation represents the line that passes through (5,8) and (9,2)

Answers

ASSUMING This is a straight line so we gotta the formula for a straight line which is y=mx+b, where m represents the slope and b represents the y intercept.

First, we know this line passes through (5,8) and (9,2) we can use these for finding the equations. When we know two points, we use this formula:

y-y=m(x-x)

The first y is 8 and the second one is 2
The first x is 5 and the second one is 9

Plug it in:

8-2=m(5-9)
6=m(-4)
6/-4=m <— simplify this
m= -3/2

*NOTE: another way to find m is by calculating it (y-y)/(x-x)

Now we know m, we have to find b.
All you gotta do is plug everything you know back into the equation y=mx+b

y=mx+b
y=-3/2x+b <— now plug in a point we know(x,y)

8=-3/2(5)+b
8=-15/2+b
8-(-15/2)=b
b=8+15/2
b=16/2+15/2
b=31/2 (now you can write be as a fraction or a decimal in your equation, depending on what your teacher told you to use)
*NOTE: it is best to use fractions instead of decimals as it is more accurate sometimes.

Now we know all the variables that need to be known, we just need to rewrite the formula of the equation so the teacher can see.

m=-3/2
b=31/2

We don’t need to plug in x or y since it could have different values (since a straight line has MANY co-ordinates)

SO OUR EQUATION IS=
y=(-3/2)x+31/2

Step-by-step explanation:

Answer:

24%

Step-by-step explanation:

Use Percent equation (p = n w) or part of the whole = percentage times the whole

so we would have

12 = n 50

12/50 = n

0.24 = n

0.24 = 24%

Here is an inequality:

< 3x + 2
Select all of the values that are a solution to the inequality.

Answers

Inequalities are used to relate unequal expressions

The values that are a solution to the inequality are: A. x = -3 and B. x = -2

The expression is given as:

[tex]\mathbf{7x + 6 < 3x + 2}[/tex]

Collect like terms

[tex]\mathbf{7x -3x < -6 + 2}[/tex]

[tex]\mathbf{4x < -4}[/tex]

Divide both sides by 4

[tex]\mathbf{x < -1}[/tex]

[tex]\mathbf{x < -1}[/tex] means that: the values of x are less than 1.

Hence, the values that are a solution to the inequality are: A. x = -3 and B. x = -2

Select the correct answer. Consider functions h and k. What is the value of ?

Answers

Answer:

Option (C)

Step-by-step explanation:

If two functions are f(x) and k(x),

(f o g)(x) = f[g(x)]

From the question given in the picture attached,

We have to find the value of (h o k)(1).

(h o k)(x) = h[k(x)]

= h[k(1)]

= h(3) [Since, k(1) = 3]

= 28 [Since, h(3) = 28]

Therefore, (h o k)(1) = 28 will be the answer.

Option (C) will be the correct option.

The correct option is C.

The calculation is as follows:

If two functions are f(x) and k(x),

(f o g)(x) = f[g(x)]

Now according to the picture

We have to find the value of (h o k)(1).

(h o k)(x) = h[k(x)]

= h[k(1)]

= h(3) [Since, k(1) = 3]

= 28 [Since, h(3) = 28]

An exterior angle of a triangle is 124°. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?

Answers

Answer:

62 degrees

Step-by-step explanation:

Let x be the measure of each non-adjacent interior angle.

By the remote interior angle theorem, the two angles mentioned add up to the exterior angle 124

x+x = 124

2x = 124

2x/2 = 124/2

x = 62

So we have two interior angles of 62 degrees each. The third interior angle is 180-124 = 56 degrees. You can also find this by solving x+x+y = 180 for y Please brainliest

The rule T(5,-3) is used for point (5,-1). Where is the translated point in the coordinate system

Answers

Answer:

Quadrant 4

Step-by-step explanation:

(5,-1), 5+5, -1-3 (10,-4) which is bottom left which is quadrant 4

The point (5, -1) is located in the fourth quadrant. Therefore, option B is the correct answer.

Given that, the rule T(5,-3) is used for point (5,-1).

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Quadrant rules:

First Quadrant: - x > 0 and y > 0. Thus, the sign of a point will be ( +, +).

Second Quadrant: - x < 0 and y > 0. Thus, the sign of a point will be ( -, +).

Third Quadrant: - x < 0 and y < 0. Thus, the sign of a point will be ( -, -).

Fourth Quadrant: - x > 0 and y < 0. Thus, the sign of a point will be ( +, -).

By studying above rules we understood (5, -1) in fourth quadrant.

The point (5, -1) is located in the fourth quadrant. Therefore, option B is the correct answer.
