Answer:

C The total cost, in dollars, for all binders and notebooks purchased

Step-by-step explanation:

x = the cost of a binder

y =  the cost of a notebook

Mario purchased 4 binders that cost x dollars each and 3 notebooks that cost y dollars each.

4x + 3y = 24

If the given equation represents this situation, which of the following is the best interpretation of 24 in this context?

The total cost, in dollars, for all binders and notebooks purchased.

The fraction that needs to be mowed is 2/3, The fraction division for the condition is x = 1 - 1/3.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given that,

Michael mows = 1/3 of the yards.

Let's say the remaining fraction is x

Remaining fraction = Total fractions - a fraction of the mowed.

x = 1 - 1/3

x = 2/3

Therefore 2/3 fraction still needed to mow.

Hence "The fraction that needs to be mowed is 2/3, The fraction division for the condition is x = 1 - 1/3".

Considering the definition of an equation and the way to solve it, for 25 words the charges will be the same.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Number of words

Being "x" the number of words, and knowing that:

If the charges are the same, the equation in this case is:

Boat Mart= Boat Bargains

1.30 + 0.12x= 1.80 + 0.10x

Solving:

0.12x - 0.10x= 1.80 - 1.30

0.02x= 0.5

x= 0.5 ÷ 0.02

x= 25

The amount of sugar that the two companies charge the same is 20 tons

The cost when the two companies charge the same is $5,015

What is breakeven amount of sugar for the two companies?

The amount of sugar that the two companies charge the same is derived at the point when the total cost of both companies are the same, bearing in mind that the total cost in this case is made of fixed cost to rent truck and variable cost, which is additional fee for each ton of sugar moved.

First company:

TC=3005+100.50x

Second company:

TC=250.75x

3005+100.50x=250.75x

3005=250.75x-100.50x

3005=150.25x

x=3005/150.25

The point t on the unit circle is ( -1/2, √3 /2 ).

The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces. Because each of these four areas occupies a quarter of the entire coordinate plane, they are collectively referred to as quadrants.

Consider the point t = - 4π/3 on the circle.

Now, the reference angle is π / 3.

- 4π / 3 is in quadrant 2 where the value of cosine is negative and sine is positive.

Therefore, the point t(x,y) will be:

( x, y ) = ( - cos ( π / 3 ), sin ( π / 3 ) )

Answer:

x = -1

y = -2

Step-by-step explanation:

We are given the following equations:

[tex]y = -2x - 4[/tex]

[tex]y = 3x + 1[/tex]

As we can see, the expressions [tex]{-2x - 4}[/tex] and [tex]3x + 1[/tex] are both equal to [tex]y[/tex]. Therefore, we can equate them:

[tex]-2x - 4 = 3x + 1[/tex]

Now we can solve for [tex]x[/tex] by making [tex]x[/tex] the subject of the equation:

⇒ [tex]-2x - 4 -3x = 3x + 1 - 3x[/tex]      [Subtracting [tex]3x[/tex] from both sides]

⇒ [tex]-5x - 4 = 1[/tex]

⇒ [tex]-5x - 4 + 4 = 1 + 4[/tex]                 [Adding 4 to both sides of equation]

⇒ [tex]-5x = 5[/tex]

⇒ [tex]\frac{-5}{-5}x = \frac{5}{-5}[/tex]                                     [Dividing both sides by -5]

⇒ [tex]x = \bf -1[/tex]

Now that we know the value of [tex]x[/tex], we can calculate the value of [tex]y[/tex] by replacing the [tex]x[/tex] with -1 in any of the equations for  [tex]y[/tex] given above:

[tex]y = 3x + 1[/tex]

⇒ [tex]y = 3(-1) + 1[/tex]

⇒ [tex]y = -3 + 1[/tex]

⇒ [tex]y = \bf -2[/tex]

Therefore, the solution to the system of equations is : x = -1, y = -2.

Answer:

x = -1

y = -2

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y = -2x - 4\\y= 3x + 1\end{cases}[/tex]

Use the method of substitution to solve for x:

[tex]\begin{aligned}& \textsf{Substitute}: & 3x+1 & = -2x-4\\& \textsf{Add $2x$ to both sides}: & 3x+1+2x & = -2x-4+2x\\& \textsf{Combine like terms}: & 5x+1 & = -4\\& \textsf{Subtract $1$ from both sides}: & 5x+1 -1& = -4-1\\& \textsf{Simplify}: & 5x & = -5\\& \textsf{Divide both sides by $5$}: & \dfrac{5x}{5} & = \dfrac{-5}{5}\\& \textsf{Simplify}: & x & = -1\end{aligned}[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\begin{aligned}& \textsf{Equation}: & y& = 3x+1\\& \textsf{Substitute in $x=-1$}: & y & = 3(-1)+1\\& \textsf{Multiply the numbers}: \quad & y & = -3+1\\& \textsf{Simplify}: & y & = -2\\\end{aligned}[/tex]

The statements that describe the graph of f(x) are (a) the vertex of f(x) is located at (−3,−1) and (c) there is a y-intercept located at (0,2).

The equation of the function is given as

f(x) = |x + 3| - 1

The above function is an absolute value function.

An absolute value function is represented as

f(x) = a|x - h| + k

Where

Vertex = (h, k)

This means that the vertex of f(x) is located at (−3,−1)

To calculate the y-intercept, we set x = 0

So, we have

f(0) = |0 + 3| - 1

Evaluate

f(0) = 2

This means that there is a y-intercept located at (0,2).

To calculate the x-intercept, we set y = 0

So, we have

|x + 3| - 1 = 0

Evaluate

x = -2

This means that there is a x-intercept located at (-2, 0).

Hence, the statements that describe the graph of f(x) are (a) the vertex of f(x) is located at (−3,−1) and (c) there is a y-intercept located at (0,2).

The angle number represents an angle adjacent to  ∠DGA is angle 2.

∠DGB.

When two angles share a shared vertex and side, they are said to be neighboring. The terminus of the rays that create the sides of an angle is referred to as the vertex of an angle. Adjacent angles can be complimentary or supplementary if they have a shared vertex and side.

Adjacent angles seem to be two angles that share a shared vertex and then a common side but do not overlap. Angles 1 and 2 in the figure are adjacent. They have the same vertex as well as a common side. In the diagram, angles 1 and 3 are not contiguous.

When two angles have a common side as well as a common vertex (corner point) but do not overlap, they are said to be adjacent.

Adjacent angles comprise two angles with the same arm and vertex. When two lines meet at the vertex as well as form a pair of opposite angles, vertical angles are formed. They share an arm and a vertex. They share a vertex of the arm but no arm.

The inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The given parameters are:

Budget = $540

New bicycle = $269.88.

4 bicycle reflectors = $10.57 each

Pair of a bike gloves = $17.76.

New biking outfits = $65.65 each.

Let the number of new biking outfits be x

So, we have

New bicycle + 4 * price of bicycle reflectors + Pair of a bike gloves + New biking outfits <= Budget

This gives

269.88 + 4  * 10.57+ 17.76 + 65.65x <= 540

This gives

329.92 + 65.65x <= 540

65.65x <= 210.08

Hence we would conclude that If Frances left the tip of 22 percent on a meal, the cost of the meal before the tip would be 18 dollars.

Let us define x to be the cost of the meal

such that we would have

x  + 22%x =  21.96

= x + 0.22x = 21.96

1.22x = 21.96

We would have to divide through the equation that we have by 1.22

x = 21.96 / 1.22

x = 18

X is the cost for the meal that  that Frances ate before she gave the tip that she did to the waiter.
