Answer:

-3 and 8

Step-by-step explanation:

take a look at the picture. Hope it helps! Mark Brainliest pleaseee :)

The x intercepts occur where x = 8 and x= -3

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2}+bx+c=0[/tex].

The x-intercept is where a line crosses the x-axis

Given,

[tex]-x^{2} +5x+24=0[/tex]

Factor the expression,

[tex]-x^{2} +5x+24=0\\-(x^{2} -5x-24)=0\\x^{2} -5x-24=0\\(x-8)(x+3)=0\\[/tex]

Therefore,

x= 8 and x = -3

Hence, the x intercepts occurs where x= 8  and x= -3

Answer:

128 markers.

Step-by-step explanation:

7 x 8 =  56

12 x 6 = 72

72+ 15 = 87

Hadley and Delaney therefore bought 128 markers all in total.

Hope I helped ! :))))))

The amount of markers Hadley and Delaney bought in all is equal to 128 markers.

Given  the following data:

To determine the amount of markers Hadley and Delaney bought in all:

First of all, we would determine the total number of marker in each box.

For Hadley:

[tex]Hadley = 7 \times 8[/tex]

Hadley = 56 markers

For Delaney:

[tex]Delaney = 6\times 12[/tex]

Delaney = 72 markers

Now, we can find the total markers:

[tex]Total \;markers = Hadley + Delaney\\\\Total \;markers = 56+72[/tex]

Total markers = 128 markers

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,-1) and (-3,-1)

The distance between them is

[tex]d = \sqrt{ ({ - 4 + 3})^{2} + ({ - 1 + 1})^{2} } \\ = \sqrt{ ({ - 1})^{2} } \\ = \sqrt{1} [/tex]

We have the final answer as

1 unit

Answer:

76

Step-by-step explanation:

multiply 19^4 first to get 76, then minus 3 from that to get 73, and add 3 back to that to get 76.

Your question has been heard loud and clear.

M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s

Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s  

Now , by law of conservation of momentum ,

Total momentum before collision = total momentum after collision

Therefore , total momentum of objects before and after collision = 30kgm/s

Answer:

C. 21

Step-by-step explanation:

We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:

BC * AC = DC * EC

Here:

AC = AB + BC = (2x + 5) + 9 = 2x + 14

BC = 9

DC = 10

EC = KC = (1 + 2x) + 10 = 2x + 11

So plug all these in:

BC * AC = DC * EC

9 * (2x + 14) = 10 * (2x + 11)

18x + 126 = 20x + 110

2x = 126 - 110 = 16

x = 8

Put this back into the expression for AB:

AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21

The answer is thus C.

Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3  cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?

Answer:

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Step-by-step explanation:

Given

[tex]Flower\ Pot = 9 in^3[/tex]

[tex]Small\ Bag = 2\frac{2}{3} in^3[/tex]

Required

How many bag of soil can fill the flower pot

To solve this,we simply divide the volume of flower pots by the small bags. This is done as follows;

[tex]Number\ of\ Bags = \frac{Flower\ Pot}{Small\ Bag}[/tex]

[tex]Number\ of\ Bags = \frac{9 in^3}{2\frac{2}{3} in^3}[/tex]

Convert fraction

[tex]Number\ of\ Bags= \frac{9 in^3}{\frac{8}{3} in^3}[/tex]

[tex]Number\ of\ Bags = 9 in^3/\frac{8}{3} in^3[/tex]

[tex]Number\ of\ Bags = 9 * \frac{3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{9 * 3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{27}{8}[/tex]

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Hence, the number of bags needed is  [tex]3\frac{3}{8}[/tex]

1 inches = $0.24

Step-by-step explanation:

9.5 inches =$2.28

$2.28 ÷ 9.5= .24

so the answer is 1 inch = $0.24

The price per inch of plant is $0.24.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Bob sets the price of the plants according to their height in inches.

A plant that is 9.5 inches high costs $2.28 in his store.

To find the price of the plant per inch:

Use division operation;

2.28 / 9.5

= $0.24 per inch.

Answer:

0.5 m³

Step-by-step explanation:

You have a rectangular prism and a cube.  Find the volume of each separately.  After solving, add the two volumes together to find the total volume.

Cube

The side length is 0.5 m.

V = a³

V = (0.5 m)³

V = 0.125 m³

Rectangular Prism

The height is 0.75 m, the width is 0.5 m, the length is 1 m.

V = lwh

V = (0.75 m)(0.5 m)(1 m)

V = 0.375 m³

0.125 m³ + 0.375 m³ = 0.5 m³

Answer:  (-4.5, -2.5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.

Answer:

Step-by-step explanation: A P E X

An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.

A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.

Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.

Hence, the correct option is 85,000.
