need help on 5 & 6 please !!!

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 )

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]

Range: { 4, -1, 3, 4}

Function: Yes it is a function

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

         subtract three from the result

        5x - 3

       (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

Slope is -1

Answer:

y= 448

Step-by-step explanation:

1.) 94=y/4-18

94+18=[tex]\frac{y}{4}[/tex]-18+18

2.) simplify

112=[tex]\frac{y}{4}[/tex]

3.) Multiply all terms by the same value to eliminate fraction denominators.

112=[tex]\frac{y}{4}[/tex]

4 · 112=4 · [tex]\frac{y}{4}[/tex]

4.) Multiply the numbers

448=y

Solution

448=y

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.

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.

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.

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

Answer:

√7 units, √98 units

Step-by-step explanation:

Pythagorean theorem

a^2+b^2=c^2. So 9+b^2=16. So b^2=7. So b=√7

a^2+b^2=c^2. SO 49+49=c^2. So 98=c^2. So c=√98.

Answer:

√7 units, √98 units

Answer:

Length of sides of triangle are: AB = 15.13, BC = 12.72, AC = 9.21

Step-by-step explanation:

We need to find the length of sides of the triangle whose vertices are A (7,4), B (-8, 6) C(1, -3).​

We have three sides of triangle AB, BC and AC

The length of side can be calculated using distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Now finding lengths of sides AB, BC and AC

i) Length of side AB

We have A (7,4), B (-8, 6)

and [tex]x_1=7, y_1=4, x_2=-8, y_2=6[/tex]

Putting values in formula and finding length

[tex]Length \ of \ side \ AB \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ AB \ =\sqrt{(-8-7)^2+(6-4)^2}\\Length \ of \ side \ AB \ =\sqrt{(-15)^2+(2)^2}\\Length \ of \ side \ AB \ =\sqrt{225+4}\\Length \ of \ side \ AB \ =\sqrt{229}\\Length \ of \ side \ AB \ =15.13[/tex]

So, Length of side AB is 15.13

ii) Length of side BC

We have B (-8, 6) and C(1, -3)

and [tex]x_1=-8, y_1=6, x_2=1, y_2=-3[/tex]

Putting values in formula and finding length

[tex]Length \ of \ side \ BC \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ BC \ =\sqrt{(1-(-8))^2+(-3-6)^2}\\Length \ of \ side \ BC \ =\sqrt{(1+8)^2+(-9)^2}\\Length \ of \ side \ BC \ =\sqrt{(9)^2+(-9)^2}\\Length \ of \ side \ BC \ =\sqrt{81+81}\\Length \ of \ side \ BC \ =\sqrt{162}\\Length \ of \ side \ BC \ =12.72[/tex]

So, Length of side BC is 12.72

iii) Length of side AC

We have A (7,4)and C(1, -3)

and [tex]x_1=7, y_1=4, x_2=1, y_2=-3[/tex]

Putting values in formula and finding length

[tex]Length \ of \ side \ AC \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ AC \ =\sqrt{(1-7)^2+(-3-4)^2}\\Length \ of \ side \ AC \ =\sqrt{(-6)^2+(-7)^2}\\Length \ of \ side \ AC \ =\sqrt{36+49}\\Length \ of \ side \ AC \ =\sqrt{85}\\Length \ of \ side \ AC \ =9.21[/tex]

So, Length of side AC is 9.21

So, length of sides of triangle are: AB = 15.13, BC = 12.72, AC = 9.21
