What is the slope of the line that passes through the points (5,11) and (14,-10)

Answers

Answer:

the picture has the answer on it

Step-by-step explanation:

The slope of the straight line that passes through the points (5,11) and (14,-10) is [tex]\frac{-7}{3}[/tex].

What is a straight line?

''A straight line is an endless one-dimensional figure that has no width. A straight line is a combination of endless points joined on both sides of a point.''

Given, two points are (5, 11) and (14, -10).

Let, the line that passes through both these points has a slope = m.

Where, m = [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex].

Here, (y₂ - y₁) = Change in the value of y.

(x2 - x₁) = Change in the value of y.

Therefore, [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex] = [tex]\frac{-10 - 11}{14 - 5}[/tex] = [tex]\frac{-21}{9}[/tex] = [tex]\frac{-7}{3}[/tex]

Hence, slope of the straight line is [tex]\frac{-7}{3}[/tex].

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options. The amount of change is different for the percent increase and the percent decrease. The ratio of the percent increase is not the same as the percent decrease. The ratio for the percent increase has a smaller denominator than the percent decrease. The ratio for the percent increase has a different numerator than the percent decrease. The original amount for the percent increase is different from the original amount for the percent decrease.

Answers

Answer:

A, C, D

Step-by-step explanation:

I took the test lol :)

(A) The amount of change is different for the percent increase and the percent decrease.

(C) The ratio for the percent increase has a smaller denominator than the percent decrease.

(D) The ratio for the percent increase has a different numerator than the percent decrease.

Percentage:A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.Example -An increase of $[tex]0.15[/tex] on a $[tex]2.50[/tex] price equals a fractional increase of [tex]\frac{0.15}{2.50} =0.06[/tex]. This represents an increase of % when expressed as a percentage.There is no mathematical restriction, therefore percentages may have various values even though the majority of % numbers fall between [tex]0[/tex] and [tex]100[/tex]. For percent changes and comparisons, it's typical to use terms like [tex]111[/tex] percent or [tex]35[/tex] percent.

Therefore, the correct options are as follows -

(A) The amount of change is different for the percent increase and the percent decrease.

(C) The ratio for the percent increase has a smaller denominator than the percent decrease.

(D) The ratio for the percent increase has a different numerator than the percent decrease.

We know that,

sum of all angles in a triangle measures 180°

Then,

(2x+6)+(3x-25)+y= 180°

2x+3x+y=180-6+25

5x+y=199°

Angle A and angle B are supplementary. The measure of angle B is 82.5.
What is the measure of angle A, in degrees?

Answers

Answer:

Angle A = 97.5º

Step-by-step explanation:

Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.

180 - 82.5 = 97.5

Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Angle A and angle B are supplementary. The measure of angle B is 82.5°.

Then the equation is given as,

∠A + ∠B = 180°

Simplify the equation, then the measure of the angle A will be calculated as,

∠A + 82.5° = 180°

∠A = 180° - 82.5°

∠A = 97.5°

Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.
