Slope of the line pls helpppppp
Answer:
[tex] slope(m) = \frac{3}{2} [/tex]
Step-by-step explanation:
Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):
Where,
[tex] (-14, 3) = (x_1, y_1) [/tex]
[tex] (-12, 6) = (x_2, y_2) [/tex]
Plug in the values
[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]
[tex] m = \frac{3}{2} [/tex]
The perimeter of a rectangle is the same as the
perimeter of a square. If the area of this rectangle
is x^2 + 4x – 21 and the side lengths are integers,
find:
a. the perimeter of the rectangle
b. the area of the square
Answer:
a. 20
b. 25
Step-by-step explanation:
Let find the side lengths of the rectangle,
We can complete the square.
[tex] {x}^{2} + 4x - 21[/tex]
[tex] {x}^{2} + 4x = 21[/tex]
[tex] {x}^{2} + 4x + 4 = 25[/tex]
[tex](x + 2) {}^{2} = 25[/tex]
[tex](x + 2) = 5[/tex]
[tex]x = - 7[/tex]
or
[tex](x + 7)[/tex]
[tex]x = 3[/tex]
or
[tex](x - 3)[/tex]
This means the perimeter of is
2 times -7 equal 14
2 times 3 equal 6
14+6=20.
The side lengths of the square is equal so each side length will measure 5.
[tex] {5}^{2} = 25[/tex]

Answer:
28 cubs
Step-by-step explanation:
Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.
We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.
What is the rate for a day?
6/1.5 =
6 bears produce 4 cubs a day.
Now just do 4 x 7
4 x 7 = 28
Therefore, 6 bears produce 28 cubs in 7 days.

A garden is in the shape of a square with a perimeter of 68 feet. The garden is surrounded by two fences. One fence is around the perimeter of the garden, whereas the second fence is 2 feet from the first fence on the outside. If the material used to build the two fences is $1.37 per foot, what was the total cost of the fences?
Answer:
$197.28
Step-by-step explanation:
perimeter of a square = 4 x length
length = perimeter / 4 = 68/4 = 17 ft
Price of the first fence = perimeter x price per foot
68 x 1.37 = 93.16
Perimeter of the second fence = (17 + 2 ) x 4 = 76
total price = sum of the price of the two fences
Price = 76 x 1.37 = 104.12
total price = 197.28
What steps to get the answer for -4x+7=11
Answer:
-4x=4
Step-by-step explanation:
-4x+7=11 subtract 7 add to the 11 answer-4x=4
Answer:
x=-1
Step-by-step explanation:
Move all terms not containing x to the right side of the equation.
Subtract 7 from both sides of the equation
-4x=11-7
Subtract 7 from 11
-4x=4
Divide each term and simplify
x=-1.

The formula for determining the pressure, p, exerted
on an object at a depth, h, below the surface of a
liquid is p = s + dgh, where s is the atmospheric
pressure, d is the density of the liquid, and g is the
acceleration due to gravity. Which formula
represents h in terms of p, s, d, and g?
Answer:
p = s + dgh
p - s = dgh
(p - s) / dg = h
Answer = h= p-s/dg
The formula that represents the height "h" in terms of p, s, d, and g is expressed as (p - s)/dg
Given the formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid expressed as p = s + dgh where:
s is the atmospheric pressure,
d is the density of the liquid, and;
g is the acceleration due to gravity
We are to make h the subject of the formula;
p = s + dgh
Subtract s from both sides
p - s = dgh
dgh = p - s
Divide both sides by dg
dgh/dg = (p - s)/dg
h = (p - s)/dg
Hence the formula that represents the height "h" in terms of p, s, d, and g is expressed as (p - s)/dg

Margo wants new carpet and a new wallpaper border for her bedroom. The room is 5.7 yards long and 6 7 8 yards wide. About how many square yards of carpet will she need? About how many yards of wallpaper border will she need?
Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards

What is the midpoint of the segment shown below? (-3, 4) (-6, -1)
A. (-9,3) O B.(-9/2, 3/2) C. (-9, 3/2) D. (-9/2,3)
Answer:
B) -9/2 , 3/2
That's the correct answer
The midpoint of the given segment is (-9/2, 3/2), so the correct option is b.
Where is the midpoint of the segment?For a segment whose endpoints are (a, b) and (c, d), the midpoint of that segment is given by the point:
( (a + c)/2, (b + d)/2).
In this case the endpoints are (-3, 4) and (-6, -1), using the above formula, we get that the midpoint is:
( (-3 - 6)/2, (4 - 1)/2) = (-9/2, 3/2)
We can see that the correct option is B.

The velocity of a ball thrown upward into the air is given by v(t)= -32t+96 where t is measured in seconds and velocity v in feet per second calculate the displacement of the ball between t=1 and t=4
Answer:
The displac ment between t = 1 and t = 4 is 272 feet
Step-by-step explanation:
To get the displacement of the ball, we first need to get the equation for the position of the ball with respect to time.
We can do this by differentiating the velocity equation given:
v(t) = -32t +96
integrating between the limits of t = 1 and t = 4, we have
[tex]s = \int\limits^4_1 {-32t +96} \, dt[/tex]
[tex]s(t) = -32t^2/2 +96t[/tex]
[tex]s =[ -16t^2 +96t] t = 4, t =1[/tex]
where t = 4.
s = 256 + (96) =352 feet
Where t = 1
s = 80
Displacement of the ball = 352 -80 = 272ft
The displac ment between t = 1 and t = 4 is 272 feet
Find the number that is exactly half way between -4 and 10
Answer:
7 as a halfway of a line
3 if you were using points on a graph
Step-by-step explanation:
10--4/2=7
use midpoint formula for 3
The number that is exactly halfway between -4 and 10 is 3
The distance between two point is the amount of length between the two points.
Midpoint of -4 and 10 is 10 - (-4) gives 10 + 4
The distance between -4 and 10 is 14 units
Halfway of the length between -4 and 10 is 14 /2 (7)
The number that is exactly halfway between -4 and 10 = -4 + 7 or 10 - 7 = 3
The number that is exactly halfway between -4 and 10 is 3
