What are the coordinates of the point where the x-axis and the y-axis intersect on a coordiantest plane

Step-by-step explanation:

y = -2x² + 9x - 11 (2 complex solutions)

y = 3x² - 6x + 3 (1 distinct real solution)

y = -x² - 4x + 7 (2 real solutions)

x/4 - 5 = -8

=> x/4 = -8 + 5

=> x/4 = -3

=> x = -3 × 4

=> x = -12

So, answer is B. –12

Answer:

$280.80

Step-by-step explanation:

Given:

C = 30x+ 25y

Where,

C = total cost

x = number of pants

y = number of shirts.

If Veronica buys eight shirts and two pairs of pants

C = 30x + 25y

= 30(2) + 25(8)

= 60 + 200

= 260

C = $260

Sales tax rate = 8%

Amount of sales tax = 8% of $260

= 8/100 × 260

= 0.08 × 260

= $20.80

Total cost of the bill including 8% tax = $260 + $20.80

= $280.80

Answer:

Yes.

Step-by-step explanation:

6(64) = 6(50+14)

Using the Distributive Property, 6 needs to be multiplied by both 50 and 14.

6(50+14) = 6(50) + 6(14)

Thus, Jane is correct.

Answer:  (x+2)^2/x+2

Answer:

It depends on your situation

Step-by-step explanation:

If you have a mixed fraction, for example: 5 23/3000 + 101 777/3000 you would have to make them irrational numbers and add them. Like so: 3000x5 = 15000. 15000+23 = 15023.  15023/3000. Same process but this time you get 303777/3000. You then add the numerators (top numbers) and you'll get the sum over 3000.

For regular fractions you simply add the numerators. If your denominators are not the same, you need to find a common term that both can fit into. If the denominators are not the same, no matter the size of the fraction, you cannot add it.

Answer:

a. $9.72

b. $11.60

Step-by-step explanation:

$9.39*(1+(3.5/100)) = $9.72

$9.39*(20/100) = $1.88

$9.72+$1.88 = $11.60

Answer:

A: The line is a dotted line and the shaded part is on the right side of the line

Answer:

X = root 73

Step-by-step explanation:

Basically you have to use the slope formula and slope intercept aka y = mx+b to find the equation. The equation is: 8/3x minus 10/3 and if you were to set this equation to zero and plug in root 73 you would get 0 meaning this answer is true/right.

Step-by-step explanation:

Answer:

A. Sandra substitutes c = 925 into the equation c + (c + 750) = 2,600.

C. Sandra finds a true statement after substituting 925 into the equation.

F. When Sandra evaluates the equation with c = 925, she adds 925 to 750. Then, she adds that sum to 925. She finds that the value is 2,600.

Answer:

1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.

4)

[tex] \frac{5x - 3}{6} + \frac{x - 9}{6} [/tex]

[tex] = > \frac{5x - 3 + x - 9}{6} [/tex]

[tex] = > \frac{6x - 12}{6} [/tex]

Taking 6 common from numerator,

[tex] = > \frac{6(x - 2)}{6} [/tex]

Cancelling 6 from both numerator & denominator,

Answer:

let the larger and  smaller number be x and y respectively

first condition

x + y = 49

second condition

3x = 2y+97

3x-2y =97

Multiplying first condition by two and adding both equations

2x + 2y = 98

3x -2y = 97

5x =  195

x = 195/5 = 39

putting the value of x in

x + y = 49

y = 49 -39 = 10

Answer:

  a) y = -7/640x^2 +7/4x

  b) y = -7/640(x -80)^2 +70

Step-by-step explanation:

a) Given the equation in standard form:

  y = ax^2 +bx +c

we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.

  a·0 +b·0 +c = 0

  a·80^2 +b·80 +c = 70

  a·160^2 +b·160 +c = 0

The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...

  [tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]

A matrix solver finds the solution to be ...

  a = -0.0109375 = 7/640, b = 1.75 = 7/4

The standard-form equation for Money's path is ...

  y = -7/640x^2 +7/4x

__

b) Factoring out -7/64, we have ...

  y = -7/640(x^2 -160x)

adding and subtracting the square of the x-coefficient, we have ...

  y = -7/640(x^2 -160x +6400) +70

  y = -7/640(x -80)^2 +70

Answer:

[tex]\dfrac{7}{9}[/tex]

Step-by-step explanation:

[tex]\dfrac{x+1}{y+1}=\dfrac{4}{5}\\\Rightarrow 5x-4y=-1[/tex]

[tex]\dfrac{x-5}{y-5}=\dfrac{1}{2}\\\Rightarrow 2x-y=5[/tex]

Putting it in matrix form

[tex]\begin{bmatrix}a_{1}&b_{1}\\a_{2}&b_{2}\end{bmatrix}{\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}{c_{1}}\\{c_{2}}\end{bmatrix}\\\Rightarrow\begin{bmatrix}5 & -4\\2 & -1\end{bmatrix}\begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}-1\\ 5\end{bmatrix}[/tex]

From Cramer's rule we have

[tex]x=\dfrac{\begin{vmatrix}c_1 &b_1 \\ c_2 & b_2\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow x=\dfrac{\begin{vmatrix}-1 &-4 \\ 5 & -1\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1\end{vmatrix}}\\\Rightarrow x=\dfrac{1+20}{-5+8}\\\Rightarrow x=7[/tex]

[tex]y=\dfrac{\begin{vmatrix}a_1 &c_1 \\ a_2 & c_1\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow y=\dfrac{\begin{vmatrix}5 &-1 \\ 2 & 5\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1 \end{vmatrix}}\\\Rightarrow y=\dfrac{25+2}{-5+8}\\\Rightarrow y=9[/tex]

Verifying the results

[tex]\dfrac{7+1}{9+1}=\dfrac{8}{10}=\dfrac{4}{5}[/tex]

[tex]\dfrac{7-5}{9-5}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]

Hence, the fraction is [tex]\dfrac{7}{9}[/tex].

Answer: 3.5 *  2.5 = 8.75

Step-by-step explanation:

The factors are to be less than 10 but are should be two digit numbers. The only way this is possible would be if they had decimals.

Which two numbers below 10 can give a product less than 10 but more than 8?

3 and 3 would give 9 which is the closest to our constraints.

Both numbers cannot be similar however and have to have a decimal but the factors should be around 3 but not up to 4 as this would pass the 10.

3.5 *  2.5 = 8.75 would work.

Answer:

Step-by-step explanation:

y = 4 * x

you can replace y and x with any values, but it has to be correct. you can say 15 = 4 * 3, but that isn't correct. but you can say 16 = 4 *4

The value of the equation is y = 4x

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.

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.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = 4x   be equation (1)

On simplifying the equation , we get

when x = 1

y = 4 ( 1 )

y = 4

when x = 2

y = 4 ( 2 )

y = 8

when x = 3

y = 4 ( 3 )

y = 12

when x = 4

y = 4 ( 4 )

y = 16

Therefore , the values of y are { 4 , 8 , 12 , 16 }

Hence , the equation is y = 4x
