Answer:

(0,0)

Step-by-step explanation:

The y-intercept is where the parabola crosses the y-axis. The y-intercept is expressed as a coordinate pair, where x is always equal to 0 because the y-axis exists where x=0.

There are 2 ways to find the y-intercept of a function. The first way is to plug in 0 for x because you know that x=0 at the y-intercept. Then, solve for y.

[tex]y=0^2+3(0)[/tex]

y=0

The second, and easier, way to find the y-intercept is to use logic. Since you are plugging in 0 for x, all terms that have variables will equal 0. This means that all that is left are the constants. So, the easiest way to find the y-intercept is to just simplify the constants. Whatever this equals will be the y-value of the y-intercept. Since there are no constants written in this equation, the constant must be 0. If 0 is the constant, then that must mean that the y-value of the intercept is 0.

Answer:

2p - 4

Step-by-step explanation:

Hello!

Let's start by deciphering what the wording is saying.

So we see he reads 4 less than 2 times the number of pages he read yesterday.

Note the words I put in bold. They're in bold because they signal our operations.

Note the fragment I underlined. It is underlined because that underlined portion refers to our variable, p.

So the amount of pages read is 4 less than 2 times p.

Well, 2 times p is 2p, and 4 less than 2p is 2p - 4

Answer:

x = 101 degrees

Step-by-step explanation

Answer:

x = 101°

Step-by-step explanation:

x and are same- side interior angles and sum to 180° , then

a + x = 180° , that is

79° + x = 180° ( subtract 79° from both sides )

x = 101°

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

Let larger number be X and smaller one be Y.

The two equations are :-

X = 2Y + 3

X = 2Y + 1

As you can tell, the slopes are the same and the y-intercepts are different. So, they will not intersect. Therefore, no solutions exist for this situation.

Answer:

No, they are not equivelent.

Step-by-step explanation:

If we solve both of them :

3:6 = 3/6

3/6 = 1/2

1/2 = 1:2

6:3 = 6/3

6/3 = 2/1 (just 2!)

2/1 = 2:1

So, they aren't the same because they aren't the same fraction and they don't simplify to the same answer :)

The statement proves that quadrilateral HIJK is a kite is  IH = IJ = 3 and JK = HK = [tex]\sqrt{29}[/tex] and IH ≠ JK and IJ ≠ HK.

Given

On a coordinate plane, kite H I J K with diagonals is shown.

Point H is at (negative 3, 1), the point I is at (negative 3, 4), point J is at (0, 4), and point K is at (2, negative 1).

A quadrilateral is called a kite with two pairs of equal adjacent sides but unequal opposite sides.

Firstly calculating the length of the sides of the kite using the following formula;

[tex]\rm Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For a kite quadrilateral,  HIJK will be a kite, if it's siding IJ = IH

From the graph length of I H = 4 - 1 = 3 units

Length of IJ = 0 - (-3) = 3 units

Therefore, IJ = IH = 3 units

Sides HK should be equal to JK

Length of HK is;

[tex]\rm HK =\sqrt{(1-(-1))^2+(2-(-3))^2} \\\\HK=\sqrt{(1+1)^2+(2+3)^2} \\\\HK=\sqrt{(2)^2+(5)^2\\} \\\\ HK =\sqrt{4+25} \\\\HK= \sqrt{29}[/tex]

Hence, the statement proves that quadrilateral HIJK is a kite is  IH = IJ = 3 and JK = HK = [tex]\sqrt{29}[/tex] and IH ≠ JK and IJ ≠ HK.

Answer:

a = 4

b = 26

Step-by-step explanation:

median is the middle number(s)

middle numbers are 22 and b

if the median is 24 then

that means the average if 22 and b is 24

so do the math in reverse

22 and b are 2 numbers

24 * 2 = 48
22 + b = 48

48 - 22 = 26

b = 26

mean is average

so do the math in reverse

there are 10 numbers

the average or mean is 19

so all the numbers add up to 190

3+a+10+13+22+26+27+27+28+30 = 190

a + 186 = 190

a = 4

Answer: 20.25ft

1. Find what 8 inches in scale equal for the height of the house.

we will do this step by multiplying.

2in=4.5

8=?

to find...

2x4=8

so

4.5x4=18

2. Find what 1 inch on the scale is equal to for the height of the house.

we will do this by dividing 4.5 by 2

4.5/2=2.25

3. Add both the values for step 1 and 2.

we will do this by just adding them both

18+2.25=20.25

This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!

Probability helps us to know the chances of an event occurring. The correct option is A.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that an integer is needed to be chosen between 1 to 50 both inclusive. Therefore, the most likely integer to be chosen can be known by finding the probability.

A.)The integer selected will be even.

Probability of choosing Even number = 25/50 = 0.5

The integer selected will be a multiple of 5.

Probability of choosing a multiple of 5 = 10/50 = 0.2

The integer selected will be a multiple of 10.

Probability of choosing a multiple of 10 = 5/50 = 0.1

The integer selected will be a multiple of 20.

Probability of choosing a multiple of 20 = 2/50 = 0.04

Since the probability of choosing an even number is the greatest, therefore, the integer that is most likely to be selected will be even.

Answer:

20.3

Step-by-step explanation:

4 = 0.25(w-4.3)

4= 0.25w- 1.075

5.075= 0.25w

(4/1)*5.075 = 1/4w *(4/1)

20.3 = w

Answer:

Combina los términos multiplicados en una sola función

4=0.25 (w-4.3)

4=1(w-4.3)/4

Multiplica por 1

4=1 (w-4.3) /4.

4=w-4.3/4

Multiplica todos los términos por el mismo valor para eliminar los denominadores de las funciones

4=w-4.3/4

4.4=4.w-4.3/4

Cancela los términos multiplicados q estén en el denominador

4.4=4.w-4.3/4

4.4=w-4.3

Multiplica los números

4-4=w-4.3

16=w-4.3
