Answer:

-3/2

Step-by-step explanation:

Let x = the integer:

2x^2 - 18 = 9x

2x^2 - 9x - 18 = 0

Now either factor that or use the quadratic formula if you're lazy like me.

x = -3/2 and 6, so x must be 6 because it has to be an integer.

What is (3xy^2)(-6xy^4)
krok68 [10]

Answer:

-18x^2y^6

Step-by-step explanation:

we have

(3xy^2)(-6xy^4)

Applying property of exponents

x^{m} x^{n}=x^{m+n}

(3xy^2)(-6xy^4)=(3)(-6)(x^{1+1})(y^{2+4})=(-18)(x^{2})(y^{6})=-18x^2y^6

Find y if the line through (3, 1) and (9, y) has a slope of 4.
klio [65]

Answer:

y = 25

Step-by-step explanation:

To find slope, we use this expression: \frac{y2-y1}{x2-x1}

Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.

\frac{y-1}{9-3}=4

Simplify the denominator:  \frac{y-1}{6}=4

Multiply both sides by 6 to isolate the y - 1:   y - 1 = 24

Add 1 to both sides to isolate the y:  y = 25

y = 25

Question Solve. 2 1/3−1/2x=−2/3 Enter your answer in the box.
Tcecarenko [31]

2/3 - 1/2x = -2/3 then the value of x is 6 .

The algebraic expression should often take one of the following forms: addition, subtraction, multiplication, or division. Bring the variable to the left and the remaining values to the right to determine the value of x. To determine the outcome, simplify the values.

The steps to use the calculator to determine x's value are as follows:

  • Fill in the multiplicand and product fields with the numbers (Integer/Decimal Numbers).
  • To obtain the result, press the "Solve" button now.
  • The output field will show the dividend or the x value.

given equation is

2/3 - 1/2x = -2/3

⇒7/3-x/2 = -2/3

⇒7/3+ 2/3 =x/2

⇒9/3 = x/2

⇒ x=3 x 2

⇒ x=6

therefore the value of the x is 6
