Answer:

x = -4

x = -1

Step-by-step explanation:

We have been given the following quadratic equation;

x^2 + 5x + 4 = 0

We are required to determine the roots of the above quadratic equation via graphing.

To do this we formulate the following equations;

y = x^2 + 5x + 4

y = 0 (x -axis)

We then proceed to graph these functions on the same graph. The roots of the original quadratic equation will be the points where the graphs of the above functions will intersect.

The attachment below is the graphical solution obtained from desmos graphing tool;

The graph of the functions intersect at;

x = -4 and x = -1

These are the roots of the given quadratic equation

Answer:

The graph of the given function f(x) = x² + 2x + 3 is attached with the answer. It is not from the given two options.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given equation is quadratic f(x) = x² + 2x + 3 so the curve on the graph will be parabolic.

When we put the different values of x in the input function f(x) the output function varies in the form of the parabolic curve the equation is quadratic so it will give two solutions which cut the axis at the points ( 0,3) you can see in the attached graph.

Answer:

Not all relationships are functions, but all functions are also relationships

Step-by-step explanation:

A relationship is a correspondence between two sets of values.

A relationship assigns values from an output set called range to a set and input called a domain.

On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).

In other words, if an input value [tex]x_1[/tex] is assigned two or more output values [tex]y_1[/tex], [tex]y_2[/tex], [tex]y_3[/tex] .. then the relationship is not a function. This means that not all relationships are functions.

[tex]y=\±\sqrt{x} +3[/tex]   is a relation but it is not a function.

because when x = 4 then y = 1 and y = 5.

Not all relationships are functions, but all functions are also relationships

Final answer:

A relation is a set of ordered pairs, while a function is a relation where each input value is associated with only one output value. Not every relation is a function, but every function is a relation.

Explanation:

A relation is a set of ordered pairs where each input value is associated with one or more output values. On the other hand, a function is a relation where each input value is associated with only one output value.

Not every relation is a function. For example, the relation {(1,2), (1,3), (2,4)} is not a function because the input value 1 is associated with two different output values (2 and 3). However, every function is a relation because it establishes a relationship between the input and output values.

Answer:

x = -4 and x = -12

Step-by-step explanation:

x^2 + 16x + 48 = 0 is to be factored.

Note that 48 is the product of 4 and 12 and that the sum of 4 and 12 is 16.

Therefore,

x^2 + 16x + 48 = 0 in factored form is:

(x + 4)(x + 12) = 0, so that x + 4 = 0 → x = -4, and

                                        x + 12 = 0  → x = -12

Answer:

(x + 4) (x + 12)

Step-by-step explanation:

to factor x² + 16x + 48 = 0, you need to find 2 numbers that when multiplied together give you 48 and when added together give you 16

you can list the factors of 48 and see what adds up together to give you 16, but here is a hint:

the numbers probably end in a 2, 4, 0, 6, 5, or 1, as a pair of these numbers added together give us 6. i looked at a factor chart and saw that 12 and 4 that when added together, give us 16 and when multiplied, give us 48

in factored form it looks like the following:

(x + 4) (x + 12)

this would be the answer in factored form

Answer:

24,74

Step-by-step explanation:

the price with tax= 34 : 100 x 107= 36.38

( start price : 100% x 100% with the 7% tax)

now you can calculate the discount = 36.38 ; 100 x 68= 24.74

( start price : 100% x 68 because the full price is 100% but there goes 32 from off so 100-32 = 68)

A percentage is a way to describe a part of a whole. The final cost of the shirt is $24.74.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The original cost of the shirt is $34, now since a 32% discount is given the cost will be,

$34 - (32% of $34)

= $34 - $10.88

= $23.12

Further, 7% tax is paid on the cost of the shirt after the discount, therefore, the final cost will be,

Final cost = $23.12 + (7% of $23.12) = $24.74

Hence, the final cost of the shirt is $24.74.

Answer: Edgur eats 12 ounces of popcorn. Before he ate any, he had 2 pounds of popcorn. How much popcorn, in ounces, of popcorn does Edgur have now? Edgur has 20 ounces of popcorn.

Step-by-step explanation:

Pounds to ounces: 1 pound = 16 ounces.

2 * 16 = 32.

He ate 12 of those ounces. 32 - 12 = 20.

Final answer:

To solve a problem involving subtraction of pounds and ounces, convert everything to ounces, subtract, and convert back if necessary. In this example, after removing 3 pounds 5 ounces from 9 pounds 8 ounces, the remaining weight is 6 pounds 3 ounces.

Explanation:

Let's create a subtraction problem involving pounds and ounces. Imagine you have a sack of potatoes weighing 9 pounds 8 ounces, and you remove a bag of potatoes weighing 3 pounds 5 ounces. How much does the sack of potatoes now weigh?

First, we need to ensure that both weights are in the same units. We have:

Initial weight: 9 pounds 8 ounces

Weight removed: 3 pounds 5 ounces

To subtract these weights, we will convert pounds to ounces for each weight, then subtract, and finally convert back to pounds and ounces if necessary.

Convert 9 pounds to ounces: 9 × 16 = 144 ounces

Therefore, the initial weight in ounces is 144 ounces + 8 ounces = 152 ounces.

Convert 3 pounds to ounces: 3 × 16 = 48 ounces

The weight removed in ounces is 48 ounces + 5 ounces = 53 ounces.

Subtract the smaller weight from the initial weight: 152 ounces - 53 ounces = 99 ounces

Now we convert 99 ounces back to pounds and ounces. Since 1 pound is 16 ounces:

99 ÷ 16 = 6 pounds with a remainder of 3 ounces.

So, the sack of potatoes now weighs 6 pounds 3 ounces.

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of squares on the other 2 sides, that is

x² + 12² = 13²

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = [tex]\sqrt{25}[/tex] = 5

Answer:

x = 25

Step-by-step explanation:

We are given a right angled triangle and we are to find the value of x.

For that, we will use the Pythagoras Theorem.

[tex] 1 3 ^ 2 = x ^ 2 + 1 2 ^ 2 [/tex]

[tex] 1 6 9 = x ^ 2 + 1 4 4 [/tex]

[tex] x ^ 2 = 1 6 9 - 1 4 4 [/tex]

[tex] x ^ 2 = 2 5 [/tex]

Taking square root on both sides to get:

Step-by-step explanation:

The ways we can get "1 counter to be white out of 2 draws" is:

1. If 1st one taken out is white and next one different color, and

2. If 2nd one taken out is white and 1st one different color

In probability, AND means MULTIPLY and OR means ADD

Here, we are actually looking for ways of 1st one white, next one different OR first one different and next one white. Let's find them separately.

1. If 1st one taken out is white and next one different color

there are 6 white and 10 total, so 1st one white is 6/10

not replaced, so now there are 9 total and 4 of them are different,so different probabililty is 4/9

We multiply these two to get:  6/10 * 4/9 = 4/15

2. If 2nd one taken out is white and 1st one different color

probabilty 1st one different color is 4/10 since 4 are different and we have total of 10

since not replaced, now we have 9 total and still 6 white.

probability of white in 2nd draw is 6/9

We multiply these two to get:  4/10 * 6/9 = 4/15

Now we add these 2 as stated earlier, so 4/15 + 4/ 15 = 8/15

Answer:

Yes he is Correct

Step-by-step explanation:

When multiply with numbers like 10,100,1000 ect or even like 20,200,2000 then you have to break it down. Since multiply by zero equals 0 anyways you will only have to focus on the number that is in front of it. And just and the zeros to the back of the number.

Answer:

Yes he is correct

Step-by-step explanation:

Whenever we are multiplying any number with  10 or multiples of ten we simply add the zeros to the end of that number.

For example:

134 x  10   =  1340

As you can see, to get the answer, you simply need to add 0 to the end of 134

Also 10 x 10 = 100

To get the answer we simply added zero to the end of ten which then give us   100

12 x 10= ?  all you need to do is to add zero to the end of 12 which will give us 120

13 x 100 =?  In this case, since the zeros are two, you will simply add two zeros to the end of  13 which will give you the answer 1300

So Marcel can find 52 times 10 by simply adding a 0 to the end of 52 to get 520 as the correct answer.
