What is an equivalent fractions

Answer:

add four to both sides of the equation

Step-by-step explanation:

x=4+4

x=8

Because the formula of quadratic equations is y = ax² + bx + c where you can see the only equation with the power of two is equation B

Equation B into quadratic equation

5x² + x = y - 4

y = 5x² + x +4

Function 5x² + x = y - 4 is quadratic .

Hence option B is correct .

Given , Linear and Quadratic function.

Standard form of quadratic function : y = ax² + bx +c

a = coefficient of x² .

b = coefficient of x .

c = constant .

Rearranging the function,

5x² + x = y - 4

y = 5x² + x - 4

Comparing the equation with standard form,

a = 5

b = 1

c = -4

Hence option B is correct .

Answer:

p=19

Step-by-step explanation:

since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:

([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]

now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]

in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]

the equation now:

[tex]x^{19}[/tex]=[tex]x^{p}[/tex]

since the exponents are at the same base, we can solve the equation

19=p

so p is 19

Step-by-step explanation:

replace x with 3 and solve

The robot does not meet both of Fernando's expectations.

A represents the number of minutes the robot filters air.

W represents the number of minutes the robot filters water.

Inequality is a statement stating two expressions are not equal.

Expectation 1:

21A + 14W > 512

Given A=15 minutes

W=5 minutes

So, 21A + 14W =21*15 +14*5 =370

370<512

So, the robot does not meet Fernando's first expectation.

Expectation 2:

0.36 A + 0.6W < 9

A=15 minutes

W=5 minutes

So, 0.36 A + 0.6W =0.36*15+0.6*5 = 8.4

8.4<9

So, the robot meets Fernando's second expectation.

Hence, the robot does not meet both of Fernando's expectations.

Answer is 3

Step-by-step explanation:

first what you do is you rearrange the numbers so the eqaution is -2x+4=-2

SO what you do is (4) - 4 to cancel it out then you do the same thing on the other side so (-2)-4=-6 so the equation now is -2x=-6 then you divide -2 to cancel it out and you do the same thing -6 divide by -2 is 3 so the answer is 3

Answer:

The answer is 648

Answer: 5 + 5w

Step-by-step explanation:

We can use the variable x to describe each additional hour, although the vairable can be substituted for any other vairable.

We know that the main cost for one hour is $5, and that each additional hour will cost $5.

Therefore, the equation to reflect this situation would be 5 + 5w, because the first 5 represents the first hour, and the 5w represents how much each hour costs. If you rent two extra hours, then the cost would end up being 15, because the equation would become: 5 + (5x2) = 15.

The equation is 5 + 5w. Hope this helps, and good luck!

Answer:

see explanation

Step-by-step explanation:

∠ AOB = 360° - 264° = 96°

The altitude OM bisects ∠ AOB and the base AB

(a)

∠ MOB = 0.5 × 96° = 48°

Using the cosine ratio in right triangle MOB

cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{OB}[/tex] = [tex]\frac{18}{r}[/tex] ( OB is the radius r of the circle )

Multiply both sides by r

r × cos48° = 18 ( divide both sides by cos48° )

r = [tex]\frac{18}{cos48}[/tex] ≈ 27 cm ( to the nearest cm )

(b)

Using the tangent ratio in the right triangle MOB

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MB}{OM}[/tex] = [tex]\frac{MB}{18}[/tex] ( multiply both sides by 18 )

18 × tan48° = MB then

AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )

Step-by-step explanation:

Answer:

It would take 12.1 years.

Step-by-step explanation:

We are given with $3000 invested in bank pays 6.75% interest compounded semi annually to the nearest 10th. We are asked to find the number of years the bank reaches $6700.

Let's use the compound interest formula.

[tex]A= P(1+\frac{r}{n}) ^{nt}[/tex]

We know A=6700

P=3000

r =0.0675

n=2(because compounded semiannually)

t =?( we need to find it)

Plug in the known values into the formula.

[tex]6700=3000(1+\frac{0.0675}{2}) ^{2*t}[/tex]

Simplify and solve for 't'

Divide both sides by 3000

[tex]2.23333= (1.03375)^{2t}[/tex]

Take log on both sides

[tex]log(2.23333) = 2t log(1.03375)[/tex]

Divide both sides by log(1.03375)

24.2067=2t

Divide both sides by 2.

t=12.10...

To round to nearest 10th, we get t=12.1 years.
