Simultaneous equations
y=x+2
y=x^2

Answers

Answer:

(- 1, 1 ) and (2, 4 )

Step-by-step explanation:

Given the 2 equations

y = x + 2 → (1)

y = x² → (2)

Substitute y = x² into (1)

x² = x + 2 ( subtract x + 2 from both sides )

x² - x - 2 = 0 ← in standard form

(x - 2)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x + 1 = 0 ⇒ x = - 1

Substitute these values into (1) for corresponding values of y

x = 2 → y = 2 + 2 = 4 ⇒ (2, 4 )

x = - 1 → y = - 1 + 2 = 1 ⇒ (- 1, 1 )

Clockwise from top left, the angles formed with line c are blank, blank, blank, 114 degrees; with line d are blank, blank, 68 degrees, blank; with line e are blank, 112 degrees, blank, blank; with line f are blank, blank, 66 degrees, blank. Which streets are parallel? Check all that apply. c || d c || e c || f d || e d || f e || f

Answers

Answer:

The answer is "c || f  and d || e".

Step-by-step explanation:

Its acute collision angle between e and t is:

[tex]\to 180^{\circ}- 112^{\circ} = 68^{\circ}[/tex]

Its angle refers to the acute corner of d, so d and e are parallel to its extreme angle of crossroads between c and t is:

[tex]\to 180^{\circ} -114^{\circ} = 66^{\circ}[/tex]

Its angle is identical to the acute angle of, f so, that c and f are parallel. [tex]d | |e, c || f[/tex]

All "corresponding" to extreme angles at crossings of t. Thus the associated points are connected to their congruence.

Manoj and Tamar are arguing about a number trick they heard.

Tamar tells Andrew to think of a number, multiply it by five and

of a number, add five and multiply the result by three. Andrew

says that whichever way he does the trick he gets the same

answer.

a. What was the number Andrew started with?

b. What was the result Andrew got both times?

c. Name another set of steps that would have resulted in the

same answer if Andrew started with the same nu

Answers

Answer:

a .  Andrew's started with number 9

 b. 42

 c. 4x + 6 = (x+12)*2

Step-by-step explanation:

Let the Andrew's number is x

Tamar tells Andrew to think of a number, multiply it by five and

         subtract three from the result

        5x - 3

Manoj tells Andrew to think   of a number, add five and multiply the result by three.

       (x +5)*3

as he was getting the same answer so both the numbers will be equal

5x -3 = (x+5)*3

5x - 3 = 3x + 15

2x = 18

x = 9

a. Andrew's started with number 9

b. (1) 5x- 3 = 5*9 - 3

        = 42

  (2) (x + 5)*3

        = 14*3 = 42

c. Think of a number, then multiply it with 4 then add 6 in it

   Think of a number add 12 in it then then double it.  

   4x + 6 = (x+12)*2

    x = 9

Is BAK ~ JOL? Explain your reasoning.

Answers

Answer:

Since the ratios are not equal the triangles are not similar

Step-by-step explanation:

Triangle Similarity

For both triangles to be similar, their corresponding side lengths should be proportional by the same scale factor.

Triangle BAK has side lengths: BA=60, AK=38, and KB=36

Triangle JOL has side lengths: JO=50, OL=28, and LJ=26.

Calculating the ratios of the corresponding side lengths:

BA/JO=60/50=1.2

AK/OL=38/28=1.36

KB/LJ=36/26=1.38

Since the ratios are not equal the triangles are not similar

Division is one of the four fundamental arithmetic operations. The typing speed of Yousef is 54 words per minute.

What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Yousef typed a 36-word paragraph in 2/3 minutes. Therefore, the typing speed of Yousef in a minute is,

Typing speed of Yousef = 36 words/ (2/3) minutes

                                         = (36×3)/2 words per minute

                                         = 54 words per minute

Hence, the typing speed of Yousef in a minute is 54 words per minute.

1. Laura earns $115 a month babysitting. If she saves all of the
money she earns in June and July and uses it to buy a bicycle

A. $230,00
B. $43.00
C. $60.00
D. $72.00
A
B
OC

Answers

Answer:

Laura will have exactly $72.00 after purchasing the bicycle.

Step-by-step explanation:

We are given that Laura ends $115 per month of babysitting.

We also learn that she wants to save her money from June and July, which means she wants to save her money over a period of two months.

Therefore, she will earn $115 twice.

[tex]\displaystyle{\$115 \times 2 = \$230}[/tex]

Then, she wants to purchase a bicycle that costs $158, so we need to subtract the cost of the bicycle from her total earnings.

[tex]\$230 - \$158 = \$72[/tex]

Therefore, Laura will have exactly $72.00 remaining after her purchase.

Para hacer una ración de puré de papa se necesita 1/5 de kg. ¿Cuántas raciones se pueden hacer con 7/4 de kg?
Gracias

Answers

Answer:

Cantidad de raciones=  8.75 raciones

Step-by-step explanation:

Dada la siguiente información:

Para hacer una ración de puré de papa se necesita 1/5 de kg.

Vamos a pasar las cantidades a décimales:

Ración puré= 0.2kg

Kg de papa= 7/4= 1.75 kg

Ahora, dividimos la cantidad total por la cantidad unitaria:

Cantidad de raciones= 1.75/0.2

Cantidad de raciones=  8.75 raciones

Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4. Find the difference between 16 and 10. Add the difference to 16. Find the difference between 16 and 10. Add the difference to 7.5.

Answers

Answer:

Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.

Step-by-step explanation:

Given

Minutes: 10 || 16 || ?  || 48

-----Miles: 2.5 || 4 || 7.5 || 12

Required

Which statements solve for the missing value?

First, we need to calculate the ratio of minutes to mile

[tex]Ratio = \frac{Minutes}{Mile}[/tex]

When minutes = 16; mile = 4

So, we have:

[tex]Ratio = \frac{16}{4}[/tex]

[tex]Ratio = 4[/tex]

Next, we multiply the ratio by 7.5

[tex]Minutes = Ratio * 7.5[/tex]

[tex]Minutes =4 * 7.5[/tex]

[tex]Minutes = 30[/tex]

P is a point on y-axis which is equidistant from A and B.
What are the coordinates of P?

Answers

Answer:

The coordinates of P are (1,0)

Step-by-step explanation:

Midpoint

The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

We need to find the coordinates of P which is equidistant from the endpoints A=(-2,1) and B=(4,-1).

Calculate the midpoint:

[tex]\displaystyle x_m=\frac{-2+4}{2}=1[/tex]

[tex]\displaystyle y_m=\frac{1-1}{2}=0[/tex]

Thus, the coordinates of P are (1,0)

Note the midpoint does not lie on the y-axis but on the x-axis.

How much does a t-shirt cost?
How much does a hat cost?

Answers

Answer:

A t-shirt costs 10.00 pounds and a hat costs 3.00 pounds.

Step-by-step explanation:

x is a t-shirt

y is a hat

9x + y = 93.00

4x + y = 43.00

(9x + y) - (4x + y) = 93.00 - 43.00

9x + y - 4x - y = 50.00

5x = 50.00

x = 50.00/5

x = 10.00 [a t-shirt costs 10.00]

4x + y = 43.00

4×10.00 + y = 43.00

40.00 + y = 43.00

y = 43.00 - 40.00

y = 3.00 [a hat costs 3.00]
