A. x = 2, y = 7
B. x = -13, y = 7
C. x = y = 12
D. x = 5, y = 1

Answer:

2625

Step-by-step explanation:

First let's see all the possible combinations.

(Even=E, Odd= O)

1) EEEO

2) EEOE

3) EOEE

4) OEEE

5) EEEE

Now let's see what E and O possibly could be

E = 0, 2, 4, 5, 6 and 8 (5)

O = 1, 3, 5, 7, 9 (5)

Now we are just simply gonna multiply

1) EEEO = 4*5*5*5

2) EEOE = 4*5*5*5

3) EOEE = 4*5*5*5

4) OEEE = 5*5*5*5

5) EEEE = 4*5*5*5

The even contains a 0, so you can't put 0 in, so (5-1=4), there are only 4 digits for the even.

500 times 4 = 2000

5⁴ = 625

2000+625= 2625

Answer:

x = 2±3sqrt(3)

Step-by-step explanation:

(x-2)^2/3=9

Multiply each side by 3

(x-2)^2/3 *3=9*3

(x-2)^2=27

Take the square root of each side

sqrt( (x-2)^2)=±sqrt(27)

x-2 = ±3sqrt(3)

Add 2 to each side

x = 2±3sqrt(3)

Hey there! :)

Answer:

C(-1) = -5.

Step-by-step explanation:

C(x) = -4x² + 4x + 3

Plug in -1 for x to solve for C(-1):

C(-1) = -4(-1)² + 4(-1) + 3

Simplify:

C(-1) = -4 + (-4) + 3

C(-1) = -5

Answer:

C(-1)= -5

Step-by-step explanation:

This question asks us to find C(-1). We know what C(x) is, it is:

[tex]C(x)=-4x^{2} +4x+3[/tex]

Therefore, we must substitute -1 in for every x to find C(-1).

[tex]C(-1)=-4(-1)^{2} +4(-1)+3[/tex]

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, evaluate the exponent.

-1^2=-1*-1=1

[tex]C(-1)=-4(1) +4(-1)+3[/tex]

Next, multiply -4 and 1.

[tex]C(-1)=-4+4(-1)+3[/tex]

Multiply 4 and -1 again.

[tex]C(-1)=-4+ -4 + 3[/tex]

Add the numbers together.

[tex]C(-1)=-8+3[/tex]

[tex]C(-1)=-5[/tex]

The value of expression remains the same

Step-by-step explanation:

Let the given function be f(y), where

[tex]f(y) = \frac{3y}{2y}[/tex]

Lets put different values of y to finds its effect on the function

f(y) = 3y/2y

Let y = 1

f(1) = 3(1)/2(1) = 3/2

Let y = 2

f(2) = 3(2)/2(2) = 6/4 = 3/2

Let y = 3

f(3) = 3(3)/2(3) = 9/6 = 3/2

Let y = 10

f(4) = 3(10)/2(10) = 30/20 = 3/2

As we can see, no matter whatever value of y we put in the expression, the result is always the same i,e 3/2

Hence,

The value of expression remains the same

Answer:

0.005

Step-by-step explanation:

Answer:

using the equation of the line y = mx + b

m= slope

b = y intercept

y= - 1.5x - 4 m = -1.5 b = -4

y = -3x + 4 m = -3 b = 4

y = 3x m = 3 b = 0

y = 1.5x - 7 m = 1.5 b = -7

y = 7 m = 0 b = 7

Hope this helps.

Answer:

y=3x goes with m=3, b=0

y=7 goes with m=0, b=7

y=-3x+4 goes with m=-3, b=4

y=1.5x-7 goes with m=1.5, b=-7

y=-1.5x-4 goes with m=-1.5, b=-4

Step-by-step explanation:

The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.

Answer:

73.72 ft Squared

Step-by-step explanation:

First you need to find the area of the rectangle the area of rectangle is 8x10=80. Then You take that 80=3.14x2. then you find the area by dividing it. so...

1.) 80=3.14x2

3.14x2=6.28       80=6.28              (Then you divide 6.28 by 80)

                             80    80                  

Answer:

  True

Step-by-step explanation:

The measure of the angle where secants intersect outside the circle is half the difference of the measures of the intercepted arcs. A pair of tangents is a special case where the intercepted arcs meet each other. The same relation regarding arc and angle measures still applies.

The given statement is true.

The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Now, The diagram is attached below

AB  and BC are the two tangents

By exterior angle theorem

∠3 = ∠2 + ∠4

So   ∠2 = ∠3 - ∠4

Now we find angle 3  and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc

∠3 = 1/2 arc ADC

∠4 = 1/2 arc AC

∠2 = ∠3 - ∠4

∠2 = 1/2 arc ADC - 1/2 arc AC

∠2 = 1/2 ( arc ADC - arc AC)

Thus, The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.

Answer:

x + 2y = -1

Step-by-step explanation:

First, we'll find the slope.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5))      *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2

Standard form:

1/2x + y = -1/2

x + 2y = -1

The sporting goods store receives the shipment of 124 golf bags in total.

Let us assume that the number of full-sized bags = X

Then the number of collapsible golf bags = 124 - X

Cost of each full sized bags = $38.50

Cost of each collapsible bags = $22.50

Total cost of the 124 bags received by the sporting goods store = $3430

Then

(38.50)X + (124 - X)22.50 = 3430

(38.50X - 22.50X) + 2790 = 3430

16X = 3430 - 2790

16X = 640

X = 640/16

  = 40

So the number of full-sized golf bags received = 40

Then the number of collapsible golf bags received = 124 - 40

                                                                                = 84

Answer:

x = 2

y = 1

z = 3

Step-by-step explanation:

Okay, we know y=z-x.

Let's plug in that y-value into the first equation: x + 2 (z - x) -z =1

Simplify that down to x +2z -2x -z = 1

Equation 1 becomes -x + z = 1

Let's plug it into equation 3 and solve to get: 2x - (z - x) +3z = 12

Equation 3 becomes 3x + 2z = 12

Now let's use system of equations for those two equations we just found

3x + 2z = 12

-2x + 2z = 2 ------> multiplied this by 2 to simplify

subtract, and you 5x = 10, x = 2

Use x = 2 and solve for the other variables using the same method (try this on your own!) to get y = 1 and z = 3

Answer:

the solution is (-2, 1)

Step-by-step explanation:

In the first equation, substitute -2 for x.  We get:

y = -2 + 3 = 1

So the solution is (-2, 1)

The solution of system of Equations is x= -2 and y= 1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the Equation:

y= x+ 3

x= -2.

So, putting the values in equation in (1) we get

y = -2 + 3

y = 1.

Thus, the solution is x= -2 and y= 1.

Answer:

y = -2/5 or y = 1

Step-by-step explanation:

5y^2 - 2 = 3y

5y^2 - 3y - 2 = 0

(5y + 2)(y - 1)

5y + 2 = 0 or y - 1 = 0

5y = -2 or y = 1

y = -2/5 or y = 1

Answer:

y = -2/5 or y = 1

Step-by-step explanation:

5y²-2 = 3y

Add -3y on both sides

5y²- 3y -2 = 0

Factorize.

(5y + 2)(y-1) = 0

(5y+2) = 0

Subtract 2 on both sides.

5y = -2

Divide 5 into both sides.

y = -2/5

(y - 1) = 0

Add 1 on both sides.

y = 1

Answer:

2/3, 1, and 6/5

Step-by-step explanation:

This is all just a matter of substitution. The values given of x = 1, x = 4/9 and x = 1 1/3 just need to be substituted in as x itself.

If x = 1, then the expression will be as the following: 4/15÷1+0.4. Dividing anything by 1 is just the same number, so 4/15 remains the same. 0.4 as a fraction is 4/10. A common denominator is 30, as both 10 and 15 fit into 30, so:

8/30+12/30=20/30, which can be simplified into 2/3

If x = 4/9, then we just substitute again. 4/15÷4/9+0.4. Due to BIDMAS, we do 4/15÷4/9 first, and to divide fractions, we use the KCF rule of Keep, Flip, and Change. We Keep the first fraction (4/15), Change the division sign into multiplication and then Flip the second fraction so it becomes 9/4

Now, we multiply the two fractions (4/15×9/4) to get 3/5, and then adding 4/10 to that gives us just 1.

If x = 1 1/3, we do the exact same thing we did for x = 4/9 to get 6/5. Good luck.
