Answer:

d

Step-by-step explanation:

Step-by-step explanation:

The cubic function passes the x-axis only once,

so there is 1 distinct real zeroes and 2 complex zeroes.

The function has only one real zero and two complex zeroes. Then the correct option is D.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The graph of the cubic function is shown.

The intersection of the curve with the x-axis is known as the zeroes of the function.

From the graph, the curve that cut the x-axis is only one point. Then the function has only one real zero and two complex zeroes.

Thus, the correct option is D.

Answer:

106 sq meters

Step-by-step explanation:

Break the figure down. I have attached an image as you can see see below.

The figure consists of three rectangles

So Area of rectangle 1 is = 4 x 7 = 28 sq meters

So Area of rectangle 2 is = 10 x 5 = 50 sq meters

So Area of rectangle 3 is = Area of rectangle 1 = 28 sq meters as they are the same rectangles

So area of the whole figure is =  Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of whole figure is = 28 + 50 + 28

Area of whole figure is = 106 sq meters.

Answer:

The height of the mother is 147.25cm

Step-by-step explanation:

The height of the new-born panda is 15.5 centimeters.

Let the height of the mother be = x

We know from the problem that the mother is 9.5 times taller than the baby.

We can get the height of the mother by multiplying the height of the baby by 9.5.

i.e x = 9.5 X 15.5 = 147.25cm

Answer:

S = (5m+79)

Step-by-step explanation:

It is given that,

Scores won by home team = (2m + 39) points

Score won by visiting team = (3m + 40) points

We need to find the sum to represent the total points scored by the two teams m minutes past halftime.

It can be calculated by the sum of score by two teams. Let the sum is S.

S = (2m + 39) + (3m + 40)

S = 5m + 79

Hence, sum to represent the total points scored by the two teams m minutes past halftime is (5m+79)

Answer:

30 degrees

Step-by-step explanation:

Since a triangle's angle measures add up to 180, you need to set up an equation to find the missing side.

130+20+? = 180

150+?=180

180 minus 150 is 30 so the missing side is 30 degrees

Answer:

30 degrees

Step-by-step explanation:

All three angles in a triangle always add up to be 180 degrees.

Add 20 and 130 to get 150. Then, subtract 150 from 180 to get 30 degrees.

So a proportional relationship is one in which there is a . For example if you know that somebody makes $10 per hour per every one hour. This is a proportional relationship and we can use an equation to represent this.

Given that,

A food truck is selling 2 burritos for $5.

Solution,

We need to find the relationship between burritos and dollars.

2 burritos = $5

To find the value of 1 burrito. Divide 5 by 2 as follows :

[tex]1\ \text{burrito}=$\dfrac{5}{2}\\\\1\ \text{burrito}=$2.5[/tex]

Hence, the relation between burritos and dollars is " [tex]1\ \text{burrito}=$2.5[/tex]"

Answer:

(5, 0)

Step-by-step explanation:

For the first line, we can isolate x by subtracting 5y on both sides.

x=5-5y.

Now we can use substitution on the second line!

-(5-5y)+6y=-5

= -5+5y+6y=-5

=-5+11y=-5

=11y=0

y=0  

We subsitute y for the first line,

x+5(0)=5

x+0=5

x=5

We can check our work by plugging in x and y

5+5(0)=5 ✔

-5+6(0)=-5 ✔

[tex] - {4} < x < - 6 \\ [/tex]

Step-by-step explanation:

[tex]5 < - 4x - 11 < 13[/tex]

Add 11 to both sides of the inequality to make - 4x stand alone

[tex]5 + 11 < - 4x - 11 + 11 < 13 + 11 \\ 16 < - 4x < 24[/tex]

Divide both sides by - 4

[tex] - \frac{16}{4} < \frac{ - 4x}{ - 4} < - \frac{24}{4} \\ - {4} < x < - 6[/tex]

Reverse the signs

Answer:a

A

Step-by-step explanation:

Edge 2021

Answer: Option B.

Step-by-step explanation:

A linear function can be written as:

y = a*x + b

where a is the slope and b is the y-intercept.

if the line passes through the points (ax, ay) and (bx, by) then the slope is:

a = (bx - ax)/(by - ay)

In this case, we can see that the line passes through the points:

(1, 3) and (2, 1)

Then the slope is:

a = (1 - 3)/(2 - 1) = -2

y = -2*x + b

In the graph we also can see that the line intersects the y-axis at y = 5, then b = 5.

The line is:

y = f(x) = -2*x + 5.

the inverse function is such that:

g( f(x)) = x

to find the inverse function of a linear equation, we just could isolate x.

y - 5 = -2x

-y/2 + 2.5 = x

Then we could write the inverse function as:

g(x)  = - x/2 + 2.5

Now we need to see which pairs belong to this line. I just will evaluate the function g(x) in different values of x, and see which points belong to the line.

g(9) = -9/2 + 2.5 = -4.5 + 2.5 = -2

(9, -2) belongs to the line.

g(7) = -7/2 + 2.5 = -3.5 + 2.5 = -1

Then (7, -1) belongs to this line.

g(5) = -5/2 + 2.5 = 0

Then the point (5, 0) belong to this line.

We can already see that all these points are in option B, then option B is the correct one.

Answer:

Step-by-step explanation:

Let's consider an exponential function as,

f(x) = 2ˣ

Now we prepare the input-output value table to get the ordered pairs to be plotted.

f(x)     0.25     0.5          1             2            4           8

x         -2         -1            0            1             2           3    

By plotting these points we get the graph as attached.

Therefore, second option in the last attachment will be the correct option.
