- Write an equation of the line that passes through (2, -1) and (-3, 3).

Answers

9514 1404 393

Answer:

y = -4/5x +3/5

Step-by-step explanation:

The 2-point form of the equation for a line can be useful.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (3 -(-1))/(-3 -2)(x -2) -1

y = 4/(-5)(x -2) -1

y = -4/5x +8/5 -1

y = -4/5x +3/5

geometry triangles plz helpp

Answers

Okay for every triangle, the degrees have to add up to 180 degrees. For example, the triangle that has c,h and 92 degrees, have to add up to 180, which means you can subtract 92 from and 180 and you’ll get 88, and since you need to find out both C and H you can divide 88 by 2 and you’ll get 44, which therefore C and H equal 44! Now try to solve the rest!

Benett

Step-by-step explanation:

Answer: Betty

Step-by-step explanation:

Bennet isn't correct because we can plug in 300 for r. It will become 300= 50t, and solving for t, we get that it would take 6 minutes.

Betty is correct because we can change the variables r and t to y and x respectively. In this case, 50 would be the constant of proportionality, or k.

Which inequality represents all the solutions of -5x + 5 ≥ 160 − 10x? A. x ≤ -33 B. x ≥ 33 C. x ≥ 31 D. x ≤ 31

Answers

Answer:

The answer is B.

Step-by-step explanation:

Solve for x.

-5x + 5 [tex]\geq[/tex] 160 - 10x

Add 10x to both sides, and subtract 5 from both sides.

5x [tex]\geq[/tex] 155

Now, divide by 5.

x [tex]\geq[/tex] 31 is the answer

#teamtrees #WAP (Water And Plant)

The inequality represents all the solutions x ≥ 31. Then the correct option is C.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given as,

−5x + 5 ≥ 160 − 10x

Simplify the equation, we have

10x – 5x ≥ 160 – 5

5x ≥ 155

x ≥ 31

Then the correct option is C.

The ratio of the perimeter of a square to the length of a rectangle is 5:6.
The ratio of the length to the width of the rectangle is 3:2.
The perimeter of a rectangle is 60cm.
Find the area of the square.

Answers

Answer:

=225/16cm^2

Step-by-step explanation:

Given

The ratio of the length to the width of the rectangle =3:2.

The perimeter of a rectangle = 60cm.

Solution

Let length=3x

width=2x

Perimeter of rectangle=2(length + width)

2(3x+2x)=60

5x*2=60

10X=60

X=60/10

X=6

SO LENGTH =3×6=18cm

WIDTH=2×6

=12cm

Let perimeter of the square=5x

Length of rectangle=6x

6x = 18

X=18/6

X=3

SO PERIMETER OF SQUARE=5×3

4SIDE=15

Side=15/4

Area of square=15/4×15/4

=225/16cm^2

Joshua rented a movie for $4.49 from Cinema Rentals. If the movie is not returned on the due date, Cinema Rentals charges an
additional $2.25 a day until the movie is returned. If Joshua returns the movie x days after its due date, which of the following
functions represents the total cost, R(x), he paid for the movie rental?

Answers

Answer:

R(x) = 2.25x + 4.49

Step-by-step explanation:

Equation form: R(x) = mx + b

m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.

b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.

Since we know the value of m and b, we can write the equation:

R(x) = 2.25x + 4.49

Answer:

1.) slope is 6

2.) slope is -4

4.)slope is undefined

Step-by-step explanation:

1.) For one we can use the equation y2-y1/ x2-x1

First, pick any 2 points that you want to use to plug into the equation

(0, -3) and (1, 3)

Next, plug in and solve!

3-(-3)/ 1-0= 6

The slope is 6

2.) We can use this same equation for the problem and plug in!

(-1, 5) (2,-7)

-7- 5/ 2-(-1)= -4

The slope is -4!

4.) Use the same equation and find the slope!

(8, 1) and (8, 2)

2-1/ 8-8= undefined

Because we cannot divide by a 0 the slope is undefined!

4 more than the quotient 12 and a number x

Answers

More than means to add.

Quotient means to divide.

4 + (12/x)

The required expression is 4 + (12/x).

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is,

4 more than the quotient 12 and a number x

Now, converting the statement into numerical form.

Since more than is addition.

Thus, 4 more than = 4 +

and, quotient 12 and a number x = 12/x

Thus, 4 more than the quotient 12 and a number x = 4 + 12/x

this is the required expression.

Thus, the required expression is 4 + (12/x).

Write the equation of a line that is parallel to the graph of y = − 7x − 9, and passing through the point (1, 10). SHOW ALL WORK!

Answers

Answer:

y = - 7x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 7x - 9 ← is in slope- intercept form

with slope m = - 7

Parallel lines have equal slopes, thus

y = - 7x + c ← is the partial equation

To find c substitute (1, 10) into the partial equation

10 = - 7 + c ⇒ c = 10 + 7 = 17

y = - 7x + 17 ← equation of parallel line

Looking at the table given, we can assume two of the points are (9,-24) and (13,-21). To find the slope with given points, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We can plug the two points in and solve.
