Mathematics
1 answer:
Nostrana [21]1 year ago
8 0

Answer:

-1<0 then 9x+5

f(-1)=9*-1+5

f(-1)=-9+5= -4

f(0)=9x+10

f(0)=10

f(2)=9x+5=28

There is a line that includes the point (-1, -1) and has a slope of 0. What is its equation in slope-intercept form?
tresset_1 [31]

Answer:

y=-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx +b where m is the slope and b is the y intercept

We know the slope is zero

y = 0x+ b

Substituting the values for x=-1 and y=-1 from the point we are given

-1 =0 +b

b=-1

Putting this into the original equation

y = 0x+-1

y=-1

Which equations represent the line that’s passes through points (1,-5) and (3,-17)
Nutka1998 [239]

(1,-5)(3,-17)

slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6


y = mx + b

slope(m) = -6

use either of ur points...(1,-5)...x = 1 and y = -5

now we sub and find b, the y int

-5 = -6(1) + b

-5 = -6 + b

-5 + 6 = b

1 = b

so ur equation is : y = -6x + 1....or 6x + y = 1

Hope this helps!

What is the rule for finding the vertex of a formula in Standard form? Use that rule to
worty [1.4K]

The vertex is the minimum or the maximum point of the parabola.

<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

<em />

The standard form of a parabola is

f(x) = ax^2 +bx + c

The x coordinate of the parabola is calculated using:

x  =-\frac{b}{2a}

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

f(\frac{b}{2a}) = a(-\frac{b}{2a})^2 + b(-\frac{b}{2a}) + c

At the end of the calculation,

x and f(x) represent the horizontal and the vertical coordinates of the vertex.

Take for instance:

f(x) = 2x^2 + 4x - 9

The x-coordinate of the vertex is:

x = -\frac b{2a}

x = -\frac 4{2 \times 2}

x = -\frac 44

x=-1

The y-coordinate is:

f(x) = 2x^2 + 4x - 9

f(-1) =2 \times (-1)^2 + 4 \times -1 - 9

f(-1) =-11

So, the vertex of f(x) = 2x^2 + 4x - 9 is (-1,11)

See attachment for illustration of vertex of f(x) = 2x^2 + 4x - 9

There are 60 cars in a used car lot.
PilotLPTM [1.2K]

Answer:

Honda made 32 cars

Step-by-step explanation:

Total no. of cars = 60

car made by ford = 3/10 of total no of cars

car made by ford = 3/10 of 60 = 3/10* 60 = 18

car made by General Motors = 1/6of total no of cars

car made by General Motors = 1/6 of 60 = 1/6* 60 = 10

No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors

No of cars made by Honda = 60 - 18 - 10 = 32

In this lot, Honda made 32 cars.

Simplify (−6.5)(2)(−5).
Dmitry_Shevchenko [17]
65 is the answer,I just put it into a calculator,but all that really is is multiplying,a negative times a negative equals a positive so you would take -6.5×2=-13
-13×-5=65
