Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4). What are the coordinates of the fourth vertex of the rectangle?

A.
(–3, –4)

B.
(–3, –1)

C.
(7, –3)

D.
(7, 4)

Answers

Answer 1

Answer: The answer is A because a rectangle has sides that go straight down basically -3 there has to be two -3 for x coordinate and two 7 for y coordinate and the missing coordinate also has to line up with the coordinate right next to it so it must have -4 as it's coordinate so basically the coordinate vertically across from it has the same x coordinate and the coordinate horizontal from it has the same y coordinate. So it's (-3,-4)

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is negative 4. And the y-intercept of the line is 1. Then the equation of the line is given as,

y = −4x + 1

The graph of the line is given below.

Answers

so earned 56,700 in a year and had 8,788.5 held back
convert to percent

so find what percent was withhelald which is (amount held back)/(total taken from)
so it would be 8,788.5/56,700=0.155/1
percent means parts out of 100 or x/100=x% so convert the bottom number ot 100 by mulitplyint the whole fraction by 1 or 100/100 so
0.155/1 times 100/100=15.5/100=15.5%
the answer is 15.5%

A right triangle has the leg lengths of 3X and 40 and a hypotenuse of length 5X. How long are the sides?

Answers

Answer:

Hypotenuse = 10 units

Step-by-step explanation:

According to the Pythagoras theorem:

${hyp}^(2) = {(one \: leg) }^(2) + {(other \: leg)}^(2) \n \therefore \: {(5x)}^(2) = {(3x)}^(2) + {40}^(2) \n \therefore \: {25x}^(2) = {9x}^(2) + 1600 \n \therefore \: {25x}^(2) - {9x}^(2)= 1600 \n \therefore \: {16x}^(2)= 1600 \n \therefore \: {x}^(2)= (1600)/(16) \n \therefore \: {x}^(2)= 100 \n \therefore \: {x}= 10 \n$
