Answer:

a=3

Step-by-step explanation:

24=3(2a-14)-3a

distribute

24=6a-42-3a

subtract 3a from 6a

24=3a-42

add 42 to both sides

66=3a

divide 3

3=a

a=3

Answer:

y= 10+ 3x

10 is the admission fee

3x is the cost for each ticket

y is the total

The function for the total cost (y) spent by the event-goer at the event is

y = 3x+10

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given that, Admission costs $10, and each raffle ticket costs $3. There are no other possible costs.

Let the total cost be y,

Therefore, establishing the function, for x number of tickets.

y = 3x+10

Hence, the required function is y = 3x+10

Answer:

slope, m

y-intercept

Step-by-step explanation:

When writing an equation in slope-intercept form, there will be need for slope and y- intercept.

When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.

Here m is slope and c is constant.

To writing the slope intercept form of the equation,

There will be requirement of slope,

and y intercept, it will be in form of (0, a), here a will be value of y coordinate.

Answer:

SinZ=24/40 = 12/20 = 3/5

C)

The value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.

The trigonometric ratios are the ratios of sides of two sides of right angled triangle used in trigonometry. Trigonometric ratios are used to find the value of the acute angles in a right triangle when the sides of the triangle are given.

We have,

A right-angled triangle XYZ with the given values,

Angle Y = 90°

And,

YZ = 32, XY = 24 and XZ = 40,

Now,

Using the trigonometric ratios,

i.e.

[tex]Sin Z=\frac{Perpendicular}{Hypotenuse}[/tex]

i.e.

[tex]Sin Z=\frac{XY}{XZ}[/tex]

So,

[tex]Sin Z=\frac{24}{40}[/tex]

On simplifying,

We get,

[tex]Sin Z=\frac{3}{5}[/tex]

So,

The option C is the correct answer for the given triangle find out using trigonometric ratio,

Hence, we can say that the value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.

Answer:

y = 4x - 16

Step-by-step explanation:

Plug in the slope and point into y = mx + b, and solve for b:

y = mx + b

-8 = 4(2) + b

-8 = 8 + b

-16 = b

Then, plug in b and the slope into y = mx + b

y = 4x - 16 is the equation in point slope form

Answer:

x = 8/5 and y = -4/5

The method used was SUSTITUION METHOD

Step-by-step explanation:

x = -2y

2(-2y)-y = 4

-4y-y = 4

-5y = 4

y = -4/5

then

x= -2(-4/5)

x = 8/5

Given:

The equation of line is

[tex]y=-3x+2[/tex]

To find:

The equation of line parallel to given line and passes through (-5,-8).

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

On comparing the equation [tex]y=-3x+2[/tex] with the slope intercept form, we get

[tex]m=-3[/tex]

Slope of given line is -3.

Slope of two parallel lines are same. So, the slope of parallel line is -3.

Equation of line passes thorough the point (-5,-8) with slope -3 is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope of the line.

[tex]y-(-8)=-3(x-(-5))[/tex]

[tex]y+8=-3(x+5)[/tex]

[tex]y+8=-3x-15[/tex]

Subtract 8 from both sides.

[tex]y=-3x-15-8[/tex]

[tex]y=-3x-23[/tex]

Therefore, the equation of required line is [tex]y=-3x-23[/tex].

Answer:

Marissa hit the ball 12 times if she goes to bat 30 times.

Step-by-step explanation:

Given that:

Marissa hits the ball 40% of the time when she is up to bat.

Marissa gets to bat for 30 times.

Balls hit by Marissa = 40% of the times Marissa goes to bat

Balls hit by Marissa = [tex]\frac{40}{100}*30[/tex]

Balls hit by Marissa = 0.4 * 30

Balls hit by Marissa = 12

Hence,

Marissa hit the ball 12 times if she goes to bat 30 times.

Answer: Arm routine = 11 minutes

Abdominal routine = 22 minutes

Step-by-step explanation:

Let the minutes used for an arm routine be represented by x.

Let the minutes used for an abdominal routine be represented by y.

Last week, he worked out for a total of 88 minutes by doing 2 arm routines and 3 abdominal routines. This can be expressed as:

2x + 3y = 88

This week, he has completed 4 arm routines and 1 abdominal routine and spent a total of 66 minutes exercising. This can be expressed as:

4x + y = 66

2x + 3y = 88 ...... i

4x + y = 66 ...... ii

Multiply equation I by 4

Multiply equation ii by 2

8x + 12y = 352 ...... iii

8x + 2y = 132 ...... iv

Subtract iv from iii

10y = 220

y = 220 / 10

y = 22

An abdominal routine last for 22 minutes

From equation I

2x + 3y = 88

2x + 3(22) = 88

2x + 66 = 88

2x = 88 - 66

2x = 22

x = 22/2

x = 11 minutes

An arm routine last for 11 minutes
