Answer:

I think this is the answer

4+–x

–x+4

Answer:

4 y + 3

Step-by-step explanation:

y = -3/4

d/dy((2 y + 1)^2 - 4 y^2 + 2) = 4

Indefinite integral:

integral(2 - 4 y^2 + (1 + 2 y)^2) dy = 2 y^2 + 3 y + constant

Answer:

x=2  y=-4

Step-by-step explanation:

2x-y=4   solve for x

2x-0=4

2x=4+0

2x=4 . divide both sides by 2

x=2

2x-y=4 .  solve for y

0-y=4

-y=4 . divide both sides by -1

y=-4

Answer:

22.6°

Step-by-step explanation:

the cosines rule :

cos x = (24²+26²-10²)/2(24)(26)

= (576+676-100)/1248

= 1152/1248

= 0.923

so, x = cos`¹ 0.923 = 22.6°

Answer:

axb/2

Step-by-step explanation:

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2

Answer:

In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.

Step-by-step explanation:

The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.

Answer:

9 hours

Step-by-step explanation:

We can use a ratio to solve

247 dollars       171 dollars

---------------- = -------------

13 hours             x hours

Using cross products

247* x = 13*171

247x =2223

Divide each side by 247

247x/247 =2223/247

Answer:

Step-by-step explanation:

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,

x = (2 · 8 + 5 · -6) / (2 + 5)

x = (16 - 30) / (7)

x = - 14 / 7

x = - 2

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Answer:

320 cm² or 264 cm²

Step-by-step explanation:

first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²

the 2 square faces will be either 8 x 8 or 6 x 6.

If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²

If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²

(d) Using the commutative property

Step-by-step explanation:

Given

The above steps

Required

Which is not part of the process

We have:

[tex]5(2x-8)= 20[/tex]

[tex]10x - 40 = 20[/tex]

[tex]10x - 40+ 40 = 20 + 40[/tex]

[tex]10x = 60[/tex]

[tex]\frac{10x}{10} = \frac{60}{10}[/tex]

[tex]x = 6[/tex]

Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.

Other properties are:

[tex]5(2x-8)= 20[/tex] ---- Distributive

[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms

[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

Answer:

6.73 x 10 ot the power of 5

Step-by-step explanation:

Answer:

yn +y -xn

Step-by-step explanation:

Mean= sum of numbers ÷number of numbers

x= sum of n numbers ÷n

Multiply both sides by n:

xn= sum of n numbers

sum of n numbers= xn -----(1)

Let the number added be a.

After a has been added,

y= (sum of n numbers +a) ÷(n+1)

Multiply both sides by (n +1):

y(n +1)= sum of n numbers +a

sum of n numbers= y(n +1) -a -----(2)

Substitute (1) into (2):

xn= y(n +1) -a

Expand:

xn= yn +y -a

a= yn +y -xn

Let's check!

Let the numbers be 1, 2, 3 and 4.

mean, x= 10 ÷4= 2.5

n= 4

Let the new number added, a, be 7.

a= 7

mean, y= 17 ÷5= 3.4

a= yn +y -xn

a= 3.4(4) +3.4 -2.5(4)

a= 7

Thus, the expression is true.
