8p2 + 2p+ 7p? does anyone know?​

Answer:

Step-by-step explanation:

first the parenthesis

3^4/3^0=3^4

anything raised to the power of 0 is 1

(3^4)^2=3^8     you multiply the powers

3^-6 * 3^8= 3^(-6+8)=3^2

Thhe simplified form of the expression is 9

Indices are expressed as power or exponent which is raised to a number or a variable.

According to the law of indices

[tex]a^n \times a^m = a^{n+m}\\a^n \div a^m = a^{n-m}[/tex]

Given the expression

[tex]3^{-6} \times (\dfrac{3^4}{3^0} )^2[/tex]

This can also be expressed as:

[tex]=\dfrac{1}{3^6} \times (\frac{3^4}{1})^2 \ (3^0 =1)\\= \dfrac{1}{3^6} \times 3^8\\=\dfrac{3^8}{3^6}\\=3^{8-6}\\=3^2\\=9\\[/tex]

This shows that the simplified form of the expression is 9

If he need one pound of cheese for each pizza and he has seven pounds of cheese then he would be able to make 7 pizzas.

Answer:

He can make 7 pizzas.

Step-by-step explanation:

If he only has seven pounds, and it takes one pound to make one pizza, you can divide the pounds available (7) by the pounds needed to make a whole unit (1 pizza).

Answer:

Therefore, the width of the canyon is 109.09 meters.

Step-by-step explanation:

* 160/22 = k (Scale Factor)

  7.2727 = k

* Let x be the width of the canyon

 x / 15 = k

 x / 15 = 7.2727

 x = 7.2727 (15)

 x = 109.09 m

The width of the canyon is 109.09m.

Here we assume x be the width of the canyon.

The k(Scale factor) should be

= [tex]160 \div 22[/tex]

k =  7.2727  

So,

[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]

 x = 109.09 m

Answer:

Market price = Rs. 6,000

Step-by-step explanation:

Given:

Cost price = R.s 4,000

Profit after discount = 20%

Discount = 20%

Find:

Market price

Computation:

Sales price = Cost price[1+Profit after discount]

Sales price = 4,000[1+20%]

Sales price = 4,800

Market price = Sales price[100/(100 - Discount)]

Market price = 4,800[100/(100 - 20%)]

Market price = Rs. 6,000

Answer:

2.25 ft

Step-by-step explanation:

Perimter= 28ft

W= x ft

L= 3x+5

but

P=2L+2W

substitute

28=2*(3x+5)+2x

28=6x+10+2x

collet like terms

28=8x+10

28-10= 8x

18=8x

divide both sides by 8

x= 18/8

x=2.25 ft

Hence the width is 2.25 ft

Answer:

x = 2

Step-by-step explanation:

Given

3(x - 4) = 2(- 2x + 1) ← distribute parenthesis on both sides

3x - 12 = - 4x + 2 ( add 4x to both sides )

7x - 12 = 2 ( add 12 to both sides )

7x = 14 ( divide both sides by 7 )

x = 2

Answer: 2=x

Step-by-step explanation:

3(x-4)=2(-2x+1) <- multiply number outside of parentheses by numbers inside parentheses

1)3x-12=-4x+2

2)-3x      -3x <- subtract -3x

-12=-7x+2 <- what you should have after

3)-2      -2 <- subtract 2

-14=-7x <- what you should have after

4)/-7 /-7 <- divide by -7

2=x <- what you should have after

/= divide

remember: negative multiplied by a negative equals a positive, and a negative multiplied by a positive equals a negative.

Answer:

a + b = 50 (Two numbers total 50)

b = a - 6 (one number is 6 less than the other)

Since we have a value, we can use the substitution metod:

a + a - 6 = 50

Simplify:

2a - 6 = 50

From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.

2(a) -6= 50

2a-6= 50

six goes and adds to 50 on the other side

2a = 56

divide both sides by 2

a= 28

final answer 28

Answer:

16km

Step-by-step explanation:

Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2

So if we apply it to this situation we get,

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2= 400 - 144

b^2= 256

b= 16

So the answer is 16km

Answer:

C.

Step-by-step explanation:

Answer:

m∠AYB = 85°

m∠C = 50°

Step-by-step explanation:

By is the angle bisector of ∠ABC,

Therefore, m∠1 = m∠2 = 30°

m∠3 = 35°

m∠AYB + m∠YAB + m∠ABY = 180°

m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]

             = 180° - [(30° + 30°) + 35°]

             = 180° - 95°

             = 85°

m∠A + m∠B + m∠C = 180°

2(30°) + 2(35)° + m∠C = 180°

60° + 70° + m∠C = 180°

m∠C = 180° - 130°

m∠C= 50°

The equation of the line in the slope-intercept form will be:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  

From the attached graph, taking two points

Finding the slope between (0, 0) and (-10, 70)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]

[tex]m=\frac{70-0}{-10-0}[/tex]

[tex]m=-7[/tex]

Determining the y-intercept:

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear that:

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = -7 and b = 0 in the slope-intercept form

y = mx+b

y = -7x + 0

y = -7x

Therefore, the the equation of the line in slope-intercept form will be:

Answer:

(4,2)

Step-by-step explanation:

Just by looking at the graph, you can see that they intersect at (4,2). But just to check:

x - 2 = -0.5x + 4

1.5x = 6

x = 4

y = 4 - 2 = 2

(4,2)

Answer:

x = undefined

Step-by-step explanation:

Because you have an x and then remove the x the it is not pssible to tell what x was with the given information causing it to be undefined.

Answer:

y = 2x + 1

Step-by-step explanation:

According to the table:

+1 +1 +1 +1

[x] -2 -1 0 1 2

[y] -3 -1 1 3 5

+2 +2 +2 +2

y = mx + b

b is y when x = 0

m is the change in y divided by the change in m = ∆y/∆x or slope.

+2/+1 = 2 = m

y = 1 when x = 0 so b = 1

therefore y = 2x + 1
