if it cost 75 cents to play 3 games, that means it cost 25 cents per game. Multiply 21 games by 25 cents per game and you get 525, or $5.25.

Answer:

$1,031.25 will be in the account

Answer:

$1031.25.

Step-by-step explanation:

The formula for simple interest is

I = PRT/100 so substituting:

I = 750 * 7.5 * 5 / 100

Interest I =  $281.25.

Amount in account =  750 + 281.25

=  $1031.25.

Answer:

(×-8)5=20

(5×-40)=20

The distance between 178 and 313 on a number line is:  135

We know that the distance between two points a and b on a number line is equal to the absolute difference between the two numbers.

i.e. Distance between two numbers = |a-b|

Here we have:

a= 178

and b=313

This means that:

|a-b|=|178-313|=|-135|=135

Answer:

f(x) = x² - 12x + 36 = (x - 6)²

The correct answer is A.

The quadratic function that has only one \(x\)-intercept is A. [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]

A quadratic function has only one [tex]\(x\)[/tex]-intercept if it touches the [tex]\(x\)[/tex]-axis at exactly one point, which happens when the discriminant [tex](\(\Delta\))[/tex] of the quadratic equation is zero. The discriminant of a quadratic function [tex]\(ax^2 + bx + c = 0\)[/tex] is given by:

[tex]\[ \Delta = b^2 - 4ac \][/tex]

Let's calculate the discriminant for each given function to determine which one has only one [tex]\(x\)[/tex]-intercept.

Option A: [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]

[tex]\[ a = 1, \, b = -12, \, c = 36 \][/tex]

[tex]\[ \Delta = (-12)^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 144 - 144 \][/tex]

[tex]\[ \Delta = 0 \][/tex]

Option B: [tex]\( f(x) = x^2 - 13x + 36 \)[/tex]

[tex]\[ a = 1, \, b = -13, \, c = 36 \][/tex]

[tex]\[ \Delta = (-13)^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 169 - 144 \][/tex]

[tex]\[ \Delta = 25 \][/tex]

Option C: [tex]\( f(x) = x^2 + 13x + 36 \)[/tex]

[tex]\[ a = 1, \, b = 13, \, c = 36 \][/tex]

[tex]\[ \Delta = 13^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 169 - 144 \][/tex]

[tex]\[ \Delta = 25 \][/tex]

Option D: [tex]\( f(x) = x^2 + 20x + 36 \)[/tex]

[tex]\[ a = 1, \, b = 20, \, c = 36 \][/tex]

[tex]\[ \Delta = 20^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 400 - 144 \][/tex]

[tex]\[ \Delta = 256 \][/tex]

Only option A has a discriminant of 0, which means it has exactly one \(x\)-intercept.

Answer:

y = -2 2/5

Step-by-step explanation:

-3(y+3)=2y+3

-3y - 9 = 2y + 3

-3y - 2y = 3 + 9

    -5y   = 12

        y = 12/-5  = -12/5 = - 2 2/5

-3(y+3)=2y+3

Mutiply the bracket by -3

(-3)(y)= -3y

(-3)(3)= -9

-3y-9= 2y+3

Move -9 to the other side

Sign changes from -9 to +9

-3y-9+9= 2y+3+9

-3y= 2y+3+9

-3y= 2y+12

Move 2y to the other side

Sign changes from +2y to -2y

-3y-2y= 2y-2y+12

-3y-2y=12

-5y= 12

Divide both sides by -5

Step-by-step explanation:

Answer:

A model for my number has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number is 236.

Solution:

Given that the model has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number can be found out by,

[tex]\bold{\begin{array}{l}{=\text { (number of hundreds block } \times 100)+(\text { number of tens block } \times 10)+} \\ {\text { (number of ones block } \times 1)}\end{array}}[/tex]

Given that number of one blocks = 6 blocks. Hence we get [tex]6 \times 1=6[/tex]

Number of ten blocks = 3.Hence we get [tex]3 \times 10 = 30[/tex]

Number of hundred blocks = 2 .Hence we get [tex]2 \times 100=200[/tex]

 So the model number = 6 + 30 + 200

 =236

Hence the model number is 236.

A. Counterclockwise rotation 90 about the origin

Step-by-step explanation:

All we have to do is make the 270°-clockwise [90°-counterclockwise] rotation to map it exactly on q' and p'.

I am joyous to assist you anytime.

Option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The graph shows the parallel lines p, q and p', q' in the plane.

The parallel lines p and q coincide with parallel lines p' and q' when we transformed the parallel lines by counterclockwise rotation 90°  about the origin.

After this transformation of rotation, the parallel lines p and q will coincide with parallel lines p' and q'.

Hence we can conclude that option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.

Answer:

x=0, y=-5

Step-by-step explanation:

The system is

(1)  5x+3y=-15  

(2) -8x-2y=10

Let's solve it by elimination.  In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated

Multiply (1) by 2 and (2) by 3

(1) 10x+6y=-30

(2) -24x-6y=30

Add the two equations

10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0

Now replace this value in any equation, for example in (1)

6y=-30 ----> y=-30/6----> y=-5

Answer:  The required solution is (x, y) = (0, -5).

Step-by-step explanation:  We are given to solve the following system of equations by the method of substitution or elimination :

[tex]5x+3y=-15~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-8x-2y=10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

We will be solving the given system by substitution method.

From equation (ii), we have

[tex]-8x-2y=10\\\\\Rightarrow -4x-y=5\\\\\Rightarrow y=-4x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (i), we get

[tex]5x+3(-4x-5)=-15\\\\\Rightarrow 5x-12x-15=-15\\\\\Rightarrow -7x=0\\\\\Rightarrow x=0.[/tex]

From equation (iii), we get

[tex]y=-4\times0-5=-5.[/tex]

Thus, the required solution is (x, y) = (0, -5).
