Answer: -36

Step-by-step explanation:

Answer:

(40÷4)+(8÷4)

(24÷4)+(24÷4)

Step-by-step explanation:

1 box holds —> 4 cup cakes

x boxes holds —> 48 cup cakes

cross multiply

48 × 1 = 4 × x

48 = 4x

[tex] \frac{ \\ 48}{4} = \frac{4x}{4} [/tex]

x = 12

since the number of boxes needed to hold 48 cup cakes are 12 we need to look for an expression that is equivalent with our figure.

lets try

(24 ÷ 4) + (20 ÷ 4)

= 6 + 5

= 11 (Not correct)

(40 ÷ 4) + ( 8 ÷ 4)

= 10 + 2

= 12 ( correct)

(40 × 4) + ( 8 × 4)

= 160 + 32

= 192(Not correct)

(24 ÷ 4) + (24 ÷ 4)

= 6 + 6

= 12(correct)

48 × 4

= 192(Not correct)

The system of equations that represents this situation is D + Q  =24 and 10D + 25Q = 465 with 15 and 9 quarters and dimes respectively.

Given that

let the quarter be represented by Q and dimes with D

D + Q  =24 (multiply this by 10)

10D  + 10Q = 240

10D + 25Q = 465

Subtracting both the equations:

15Q  =225

Q = 225/15 = 15 quarters

Now putting this value in equation 1st we get

D = 24-15 = 9 dimes

The standard form of the equation Y=(x-2)² + 4 is written as y=x²-4x+6.

A standard form serves as a gauge for how widely scattered the data is in comparison to the mean.

The data are grouped around the mean when the standard deviation is low.

A parabola with the point at its vertex represents this equation (2,4). On a coordinate plane, the equation can be graphed, revealing a parabola that extends upwards and has a minimum value of 4 at the point (2,4).

The factored version of the equation

Y=(x-2)² + 4 is y =  (x-2) (x-2) + 4

This representation of the equation demonstrates that it is the result of two binomials. When the common element is eliminated, the equation can be made simpler (x-2).

The equation is now more easily expressed as

y = (x-2) (x-2) + 4 = (x-2)² + 4.

Expanded form of the equation

Y=(x-2)² + 4 is expressed as y = x² - 4x + 6.

This representation of the equation demonstrates that it is the outcome of expanding (x-2)².

You may use this equation to determine the vertex of the parabola, which is (2,4). The vertex is the location where the parabola's value is at its lowest.

And, the function will be:

g (x) = –x^2

Then, vertically stretched by a factor of 5, we will get:

g (x) = –5x^2

Last, translated 3 units down, we will get:

g (x) = –5x^2 – 3

On solving the quadratic function x²+6x+8, the solutions x = -4 and x = -2 are obtained.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The given quadratic function is - x²+6x+8

To solve the function first multiply - 8 ×  x² = 8x²

Take the LCM of  8x².

8x² = 2 × 2x × 2x

Now, we need to form such two numbers that if added or subtracted gives 6x and when multiplied gives 8x².

8x² = 4x × 2x

6x = 4x + 2x

Factorize the equation using the numbers obtained -

= x²+6x+8

= x²+ 4x + 2x + 8

= x(x + 4) +2(x + 4)

= (x + 4)(x + 2)

This gives the value as x = -4 and x = -2.

Therefore, the solution points are x = -4 and x = -2.

Step-by-step explanation:

Answer:

[tex]56.8x+39.2[/tex]

Step-by-step explanation:

First, you must distribute the 2's to the expressions:

2(4.4x+7.6) = 2(4.4x) + 2(7.6) which is equal to 8.8x + 15.2 and;

2(24x+12) = 2(24x) + 2(12) = 48x + 24

Now add both: 8.8x + 48x + 24 + 15.2 ; combine like terms.

56.8x + 39.2 is what you get from doing that.

This cannot be simplified any further, and therefore is your answer:

What is linear inequality?

A linear inequality is a mathematical statement that describes a relationship between two or more variables that form a half-plane when graphed. The equation of a linear inequality is in the form of "ax + by < c" or "ax + by > c" or "ax + by <= c" or "ax + by >= c", where x and y are variables, and a, b and c are constants.

An inequality that could be used to determine the minimum number of gallons, g, of gasoline Darla would need to drive 120 miles to her brother's house is:

g >= 120/37.5

This inequality states that the number of gallons, g, must be greater than or equal to the number of miles Darla needs to drive, 120, divided by the number of miles per gallon her car gets, 37.5. This is because Darla wants to ensure that she has enough gasoline to make the trip, and she may not want to risk running out of gas on the way.

Another way to write this inequality is

g * 37.5 >= 120

This inequality represents the same meaning as before, we multiply g by the number of miles per gallon the car gets, 37.5 and it should be greater than or equal to the distance she needs to travel which is 120 miles.

Hence, the inequality can be written as g * 37.5 >= 120.

The amount invested in each mutual fund is $400 and $1200 respectively

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 10 and 8x − 4y = 2

Let represent the amount the first fund get by x and the amount the second fund get by y.

Therefore x+y = 1600 equation 1

and 9/100 × x + 4/100 × y = 84

9x/100 + 4x/100 = 84

multiply through by 100

9x + 4x = 8400 equation 2

using elimination method

9x+ 9y = 14400 equation 3

9x + 4y = 8400 equation 4

subtract equation 4 from 3

divide both sides by 5

y = 6000/5

y = $1200

substitute 1200 for y in equation 1

To find the formula of an exponential function from a table, you need to identify two points that fall on the exponential curve, and then use them to find the function's base.

The first step is to identify two points that fall on the exponential curve. Look for two pairs of x and y values that are not too far apart. For example, (1, 2) and (2, 4) are good choices.

Next, you use these two points to find the base of the function, which is the number b in the equation y = b^x. To do this, you take the ratio of the y-values and the logarithm of that ratio with base b. The logarithm of the ratio is equal to the difference of the x-values.

For example, if you have (1, 2) and (2, 4) you can find the base by taking log2(4/2)=log2(2)=1, which means that the base of the function is 2.

Now you have the base you can write the formula of the exponential function as y = 2^x.

It is important to note that you can use the same process with other bases, such as base 10 or base e, depending on the problem and the logarithm function you have available.
