Speedy Cav Company uses the following to determine ride costs:
A $5.00 flat fee for a ride.
An additional $0.75 for each mile traveled.
Which equation represents the cost of a car ride from Speedy Cab Company?
A. t = 5x + 0.75
B. t = 0.75 + 5
C. t = 0.75x + 5
D. t = 5x - 0.75
Which of the following inequalities is the solution to the number line?
Answer:
A
Step-by-step explanation:
- 5x + 4 > 9 ( subtract 4 from both sides )
- 5x > 5
Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.
x < - 1
Which is represented by the given number line
Select the expression equivalent to 4(– 7) + 8.
Answer:
-20

-28 + 8 =
-20
An expression equivalent to 4(– 7) + 8 would be:
8 + 4(-7)
This is true because of the commutative property which states that a+b=b+a
Answer:
-20
Step-by-step explanation:
It is very simple!
4x-7= -28
-28+8=20
if dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3
Answer:
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0
Step-by-step explanation:
Step(i):-
Given that the slope of the tangent
[tex]m = \frac{dy}{dx} = x(y-1)[/tex]
m = -2( 3-1) = -4
Given point x = -2
y = f(-2) =3
∴The given point ( x₁ , y₁) = ( -2 ,3)
Step(ii):-
The equation of the tangent line passing through the point (-2,3)
[tex]y - y_{1} = m(x-x_{1} )[/tex]
[tex]y -3 = -4(x-(-2))[/tex]
y -3 = -4( x+2)
y-3 = -4x -8
4x + y -3+8=0
4x +y +5=0
Step(iii):-
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0

-40 =-5y + 8x
x-intercept:
y-intercept:
Answer:
Y Intercept = (0,8)
x Intercept = (-5,0)
Step-by-step explanation:
Rearrange to y=mx+c
-5y= -40-8x
-5y=-8x-40
Divide both sides by -5
y=8/5x+8
Y Intercept = (0,8)
X intercept; Find x when Y=0
0= 8/5x+8
8/5x = -8
x= -5
Hence;
X Intercept = (-5,0)

5x + y = 9
Answer:
x=4, y=-11. (4, -11).
Step-by-step explanation:
3x+2y=-10
5x+y=9
--------------
3x+2y=-10
-2(5x+y)=-2(9)
--------------------
3x+2y=-10
-10x-2y=-18
-----------------
-7x=-28
7x=28
x=28/7=4
5(4)+y=9
20+y=9
y=9-20=-11

Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-6, -4),A(−6,−4),A, left parenthesis, minus, 6, comma, minus, 4, right parenthesis, comma B(-4,-4)B(−4,−4)B, left parenthesis, minus, 4, comma, minus, 4, right parenthesis, C(-4, -2)C(−4,−2)C, left parenthesis, minus, 4, comma, minus, 2, right parenthesis, and D(-6, -2)D(−6,−2)D, left parenthesis, minus, 6, comma, minus, 2, right parenthesis.
What is the perimeter of rectangle ABCDABCDA, B, C, D?
units
The perimeter of the rectangle is 8 units
The coordinates of the rectangle is given as:
[tex]A = (-6,-4)[/tex]
[tex]B = (-4,-4)[/tex]
[tex]C = (-4,-2)[/tex]
[tex]D = (-6,-2)[/tex]
Start by calculating the distance between the vertices using the following distance formula
[tex]d=\sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]AB=\sqrt{(-6 --4)^2 + (-4 --4)^2}[/tex]
[tex]AB=\sqrt{4}[/tex]
[tex]AB=2[/tex]
[tex]BC=\sqrt{(-4 --4)^2 + (-4 --2)^2}[/tex]
[tex]BC=\sqrt{4}[/tex]
[tex]BC=2[/tex]
[tex]CD=\sqrt{(-4 --6)^2 + (-2 --2)^2}[/tex]
[tex]CD=\sqrt{4}[/tex]
[tex]CD=2[/tex]
[tex]DA=\sqrt{(-6 --6)^2 + (-2 --4)^2}[/tex]
[tex]DA=\sqrt{4}[/tex]
[tex]DA = 2[/tex]
So, the perimeter of the rectangle is:
[tex]P =AB + BC + CD + DA[/tex]
This gives
[tex]P= 2 + 2+2+2[/tex]
[tex]P= 8[/tex]
Hence, the perimeter of the rectangle is 8 units
