Solve f(x)=2, if f(x)=1/2x-3

Answer:

x = 44.3

Step-by-step explanation:

Knowing that the given figure shows a supplementary angle

⇒ Note that: Supplementary angle= 180 °

Since it already given the other two number

The equation is:

43 + 92.7 + x = 180

Adding both number together : 43 + 92.7

135.7 + x = 180

Subtract 135.7 from both sides

135.7 -135.7 +x = 180-135.7  

x = 44.3

Hence, the value in degrees of x = 44.3 °

Answer:

Step-by-step explanation:

In this question we have given volume of cube that is 8 in³. But we know that volume of cube is a³. So ,

[tex] \implies \: a {}^{3} = 8[/tex]

Now ,

[tex] \implies \: a = \sqrt[3]{8} [/tex]

So , cube root of 8 is ,

[tex] \implies \: \boxed{\bold{a = 2}}[/tex]

Now , we are finding surface area of cube . We know that surface area of cube is 6a² . So ,

[tex] \pink{ \boxed{ Therefore, \: surface \: area \: of \: cube \: is \: 24 \: in ^{2} }}[/tex]

Let's start with 5 squared. 5 squared, or just squared in general, represents the number behind it times itself.

[tex]5^2~or~ 5*5 = 25[/tex]

Now, add 3

[tex]25 + 3 = 28[/tex]

Next, subtract 1

[tex]28 - 1 = 27[/tex]

Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.

[tex]\frac{18}{2} = 9[/tex]

Lastly, divide x by y, 27 divided by 9

[tex]\frac{27}{9} = 3[/tex]

The problem is solved! The final answer is 3

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

B = (4,6)

C = (9,6)

D = (11,6)

Since it is a strait line on six, all the points should have 6 as y. For the x's, just count how much it is away from the y-axis.

Answer:

option C

i hope it is correct

Answer:

Tbh I am not sure but it's a semi-circle prism or like semi cylinder (I think) but usually semi-circles themselves will not tessellate bc circles have no angles and when u line them up next to each other there will be gaps between them and one of the tessellation rules is that no overlapping or gaps so yeah

I am sorry lol if that's all wrong but my answer is no, I don't think that this figure is a tessellate plane

The distance he jogs in kilometers would go by 7 every hour making it proportional relationship

Answer:

Now, △DEF has interior angles with measures y°, 70°, and 20°.

By using angle sum property,

Now, we can say that,

"The two triangles are not similar because x≠y"

As one angle of measure 70 degree is common in both the triangles.

If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.

Therefore, the two triangles are not similar because x is not equal to

Step-by-step explanation:

Answer:

the triangles are not similar. If they were, they would have the same angles.

The interior angles are not congruent. We can rule out choice B and C.

Just because they have one equal angle does not make them similar. We can rule out D.

A is the best answer.

Answer:

12.56 in²

Step-by-step explanation:

Area = πr²

Substitute for pi.

A = 3.14 × r²

The diameter is 4. We divide the diameter by 2 to get the radius.

4 ÷ 2 = 2

Substitute for the radius.

A = 3.14 × 2²

Solve

A = 3.14 × 4 = 12.56 in²

Answer:

5x - 1

Find Factors:

Factors: (2x-3)(3x+2)

Their sum:

Factor the trinomial 6x²-5x-6, then find the sum of the factors .

This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .

[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]

Now , by splitting the middle term that is - 5 x :

[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]

Now , taking 3x and -2 as common :

[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]

So ,

[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]

Therefore , factors are ,

In the question we have ask to find the sum of their factors . So adding them ,

Therefore , 5x - 1 is the sum of the factors .

Answer:

The Area is: 84ft

Step-by-step explanation:

multiply "Y" and "X" and you get 78ft.

"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.

"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2

2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.

78+6=84.

By, Cross multiplying, we get

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

[tex]⇢2 {x}^{2} - 2x = 2x(x + 2) - 1( x+ 2)[/tex]

[tex]⇢2 {x}^{2} - 2x = 2 {x}^{2} + 4x - x - 2[/tex]

Here, [tex]2 {x}^{2} [/tex] from both sides will get cancelled

[tex] ⇢- 2x = 3x - 2[/tex]

[tex]⇢ - 2x - 3x = - 2[/tex]

Answer:

[tex]x=\frac{2}{5}[/tex]

Step-by-step explanation:

[tex]\frac{2 x}{x+2}-\frac{x}{x-1}=1[/tex]

[tex]\begin{aligned} & \Leftrightarrow \frac{2 x(x-1)}{(x+2)(x-1)}-\frac{x(x+2)}{(x-1)(x+2)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x}{(x+2)(x-1)}-\frac{\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-\left(x^{2}+2 x\right)}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{2 x^{2}-2 x-x^{2}-2 x}{(x+2)(x-1)}=1 \\& \Leftrightarrow \frac{x^{2}-4 x}{(x+2)(x-1)}=1 \\\end{aligned}[/tex]

[tex]\begin{aligned}& \Leftrightarrow x^{2}-4 x=(x+2)(x-1) \\& \Leftrightarrow x^{2}-4 x=x^{2}-x+2 x-2 \\& \Leftrightarrow x^{2}-4 x=x^{2}+x-2 \\& \Leftrightarrow-4 x=x-2 \\& \Leftrightarrow 5 x=2\end{aligned}[/tex]

therefore,

Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."

By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.

We can make a right triangle with the sides: DE, FE, and DF.

Such that we know that:

DE = FE = 4

These two are the cathetus of the right triangle.

Then DF is the hypotenuse.

Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:

(DE)^2 + (FE)^2 = (DF)^2

4^2 + 4^2 =(DF)^2

√32 = DF = 5.7

The length of DF is 5.7 units.
