Actually Welcome to the Concept of the exponents and indices.

here, we should remember one thing that,

3 ^3 = 27 and 1/3^x = 3^-x

so we get as,

(3^-3)^4-x = (3^3)^2x-1

==> 3^-12+3x = 3^6x-3

since the base is same that is 3 , we equate their powers.

-12x+3=6x-3

==> 3+3 = 6x+12x

==> 6 = 18x

hence ===> x = 6/18 = 1/3

hence, x = 1/3

So, basically I can't remember how to do this the long way but I used a calculator on Desmos (the graphing one to be specific). You should be able to find tutorials on how to use it and graph problems to find their answers but if not, you can just message me and I'll walk you through how to use it.

As for the form it asked for in the question, slope-intercept form is just:

y = mx + b

m is the slope, and b is the y-intercept (the place where the line crosses the y-axis)

f(x) = (x + 2)²    ⇒   f(x) = (x - (-2))² + 0    ⇒   h = -2 ,   k = 0

Answer:

The annual profits will be 2187.5

Step-by-step explanation:

p(x) = 65x - 0.3x^2

I am guessing that the 2 was supposed to be a square.

Simply plug in the number of pies sold:

p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

Answer:

42 feet squared

Step-by-step explanation:

10% of 10% is 0.01 then 1% of 1% is also 0.01

the same number of the same number is also 0.01 at this point:

25% of 25% is 0.01.

Answer:

The answer is 1 5/12 or 17/12.

Step-by-step explanation:

First we turn 5 2/3 into a Improper fraction.

5 2/3 = 17/3

Next we change 4 to 1/4 then multiply 1/4 by 17/3.

17/3 * 1/4 = 17/12

17/12 = 1 5/12

Hope this helps! :)

Answer:

17/12

Step-by-step explanation:

5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12

Answer:

x = 6

Step-by-step explanation:

The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64 = 36

b = ±[tex]\sqrt{36}[/tex]

b = ± 6

But we know that distance is always positive, so

b = 6

I have used b in place of x if you are confused about the variable usage.

Answer:

10a - 30b + 40

Step-by-step explanation:

Multiply each term inside the ( ) by the 5 outside the ( ).

5 x 2a = 10a

5 x -6b = -30b

5 x 8 = 40

Add the terms together (don't forget that it's negative 30b)

10a + -30b + 40 = 10a - 30b + 40

Answer:

Step-by-step explanation:

Were there not several equations from which to choose?

The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}.  The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300.  Because the discriminant is negative, the quadratic has no real solutions.

The quadratic equation with no real solution is 25x²-10x+4 = 0

The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Given that, which of the equations have no real solution,

Considering the quadratic equation 25x²-10x+4 = 0

D = [tex]\sqrt{b^{2} -4ac}[/tex]

We know, when √D > 0, real roots

√D = 0, equal roots

√D < 0, imaginary roots

[tex]\sqrt{b^{2} -4ac}[/tex] =

[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]

Since, the discriminant is less than 0, therefore, its roots are imaginary.

Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

5, 10 and 11 feet.

Step-by-step explanation:

Let length of first side be x feet then

second side  = 2x feet

third side = 2x + 1 feet.

So we have the equation:

x + 2x + 2x + 1 = 26

5x + 1 = 26

5x = 25

x = 5 feet.

So first side = = 5 feet, second = 10 and third = 11 feet.
