Answer:

[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]

Answer:

x=5

Step-by-step explanation:

[tex]x(x-1)-x^2+2x=5[/tex]

expand by using distributive property

[tex]x^2-x-x^2+2x=5[/tex]

simplify

x=5

check work by substituting 5 into the original equation and simplify

use PEMDAS

[tex]5(5-1)-5^2+2(5)=5[/tex]

[tex]5(4)-25+10=5[/tex]

add and subtract  (left to right)

20-25+10=5

5=5

The equation is true, thus x=5

Answer:

Step-by-step explanation:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Answer:

rearrange the question

y - 5x = 8.................(1)

y - 8x = 9..................(2)

make y the subject formula in eqn. (1)

y = 8 + 5x................(3)

substitute

8 + 5x - 8x = 9

-3x = 1

x = -⅓

y = 8 + 5x

y = 8 + (-⅓)

y = 23/3

Step-by-step explanation:

63+36+X = 180 (interior angles of a triangle equal 180)

X = 180-99

X= 81

X+Z= 180(angles on a straight line adds up to 180)

81+y= 180

Z=180-81

Z =99

13+Z+Y=180

13+99+Y=180

Y=180-112

Y=68

Answer:

Step-by-step explanation:

Surface Area of a cylinder = 2 × area of base + lateral face

First find the area of the base

Area of Base = πr² ( pi × radius squared ) ( pi = 3.14 )

AB = 3.14 × 3²

AB = 3.14 × 9

Area of Base = 28.26

Next, find the lateral face

Lateral Face = circumference of base × altitude

( circumference of base = 2πr ) ( altitude = height of the cylinder )

LF = 2 × 3.14 × 3

Lateral Face = 18.84

Last, is the Surface Area

Surface Area of a cylinder = 2 × area of base + lateral face (formula)

SA = 2 × 28.26 + 18.84 × 5

SA = 56.52 + 18.84 × 5

SA = 56.52 + 94.2

Answer:

f(-12) = -13

Step-by-step explanation:

f(x) = x - 1

Let x = -12

f(-12) = -12-1

       = -13

Answer:

[tex]f(x) = x - 1 \\ f( - 12) = - 12 - 1 \\ \boxed{ f( - 12) = - 13}[/tex]

Note the rule

[tex]\boxed{\sf a_n=ar^{n-1}}[/tex]

Now

[tex]\\ \tt\longmapsto a_2=3(-1/2)^{2-1}=3(-1/2)=-3/2[/tex]

[tex]\\ \tt\longmapsto a_3=3(-1/2)^{3-1}=3(-1/2)^2=-3/4[/tex]

[tex]\\ \tt\longmapsto a_4=3(-1/2)^{4-1}=3(-1/2)^3=-3/8[/tex]

[tex]\\ \tt\longmapsto a_5=3(-1/2)^{5-1}=3(-1/2)^4=-3/16[/tex]

5x^3 + 6x^2 - 45x - 54

x^2( 5x + 6) -9(5x-6)

(5x+6)(x^2 - 9)

5x+6=0 x^2-9=0

5x= -6 x^2= 9

x= -6/5 x= -3 or 3

Answer:

Step-by-step explanation:

So first of all, you can rearrange your equations:

4x + 7x = 11 can be rearranged and simplified to x = 11/7

x = y + 1 can be rearranged to y = x - 1

Then you can graph them like normal by plugging in points. It should look like the following picture

Answer:

63.55

Step-by-step explanation:

1. Given that Javier's pay rate is $10.25 per hour, let's find the combined amount he earned from Monday and Tuesday by multiplying the hours worked by 10.25.

2. Now, let's add 24.6 and 38.95 to get how much he earned:

Therefore, Javier earned 63.55 dollars and cents on those two days.
