Answer:

  3

Step-by-step explanation:

The square root function (√) only gives positive values, so graphs 1 and 4 make no sense.

When x = -3, the y-value is 0, consistent with graph 3.

Answer:

11

Step-by-step explanation:

3-(-8) = 3+8

= 11

Plug in -3 for f(x) into the first equation.

-3 = x^2 - 5x + 3

x^2 - 5x + 6 = 0

Factor!

(x - 3)(x - 2) = 0

Set each binomial equal to 0 to get the x-value of the point.

x = 3

x = 2

Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.

(3)^2 - 5(3) + 3

9 - 15 + 3

-6 + 3

-3

(2)^2 - 5(2) + 3

4 - 10 + 3

-6 + 3

-3

Ordered pairs of the solutions for this system of equations: (2, -3) and (3, -3)

Hope this helps!! :)

Answer:

D) [0, ~)

Step-by-step explanation:

Domain of a Function:

the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.

For Example:

suppose, we have a function:

f(x) = 3x - 1

and it's domain is {1, 2, 3}

that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.

The given function:

Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.

and since the graph starts from x = 0 and continues towards infiinity

(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)

So, that way we got [0, ~). ^^

Answer: A

Step-by-step explanation:

Replace x by 3, and y by 2

Answer:

Step-by-step explanation:

x = 3 , y = 2

• Y= x - 1

• 2 = 3-1

• 2 = 2

Answer:

10 and 12

Step-by-step explanation:

10 and 12

if I divide 3 and 6 by 3 I get 1/2

if I divide 5 and 10 by 5 I get 1/2

1/2 is the first one listed

I cannot reduce 10/12 and get 1/2, I get 5/6

Answer:

Unit Cost = 0.6

Cost for 50 mile taxi ride = $30

Step-by-step explanation:

We are given the following information in the question:

Length of taxi ride = 28 miles

Time taken by taxi ride = 42 minutes

Cost of taxi ride = $16.80

We have to find cost of a 50 mile ride.

In order to do so, we have to find the unit cost of distance covered by ride which is the unit cost per mile of the ride that is the cost for 1 mile of taxi ride.

Our Formula:

Unit Cost = Cost for 1 mile of taxi ride = cost of taxi ride / distance covered by taxi ride

Using the values given we can use the formula so

unit cost = 16.80 / 28 = 0.6

Cost of 50 mile taxi ride

0.6 x 50 = 30

Henc costing $30 for a 50 mile taxi ride

Step-by-step explanation:

in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.

now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.

when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).

so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.

xm, ym are the coordinates of the midpoint.

xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5

ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5

so, the midpoint is (-6.5, 0.5)

3b - 3.76 = 1.34

3b = 3.76+ 1.34

3b = 5.1

b= 5.1/3

Answer:

$38 for 2 sweaters

Step-by-step explanation:

Every price for all other sweater options are divisible by 24, since it is the unit price (meaning 1 sweater = $24). 38 is not divisible by 24, but by 19. This means it does not follow the unit price. It would be a special sale.

Answer: 7 miles per hour

Step-by-step explanation:

3 1/2 miles = 7/2 miles

1/2 hours= 30 minutes

So,

In 30 mins, travelled 7/2 miles

In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles

In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.

Hence, the speed is 7 miles per hour.

Answer:

The slope is undefined.

Step-by-step explanation:

If the x value stay the same between a set of points, the slope of the line will be undefined.

Answer:

[tex]4*3=3*4[/tex]

Step-by-step explanation:

The commutative property of multiplication states that [tex]a*b=b*a[/tex].

In the first equation, we have that [tex]4*3=3*4[/tex], which is a clear application of the commutative property.

So, the answer is [tex]4*3=3*4[/tex] and we're done!

Answer:

it's the first one cause the commutative property is multiplying in any order without changing the product.... I think?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Find the zeroes of the function f ( x ) = x 2 + 12 x + 32

First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )

Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )

Set each factor equal to zero and the answer is x = − 8 and x = − 4 .

4x^2 y^3 × 2xy^4 =

4 × 2 × x^2 × x^1 × y^3 × y^4 =

8 × x^(2 + 1) × y^(3 + 4) =

8 × x^3 × y^7 =

8x^3 y^7
