The quotient of a number x and 4 is at most 5. An inequality is?
Shalnov [3]

Answer:

The inequality can be represented as:

\frac{x}{4}\leq5

Solution for the inequality:

x\leq20

Step-by-step explanation:

Given :

The quotient of a number x and 4 is at most 5.

To write an inequality for the given statement.

Solution:

The quotient of two variables a and b can be represented as : \frac{a}{b}

Thus the quotient of the number x and 4 can be represented as:

⇒  \frac{x}{4}

The quotient is at most 5 which means it is less than or equal to 5.

Therefore, the inequality can be represented as:

\frac{x}{4}\leq5

<em>Solving for</em> x.

Multiplying both sides with 4.

4\times \frac{x}{4}\leq5\times 4

x\leq20

Thus, the number must be at most 20.

Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three
otez555 [7]

Answer:

y_Q=\dfrac{21}{5}=4.2

Step-by-step explanation:

If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.

Use formula to find the coordinates of the point Q:

x_Q=\dfrac{3x_P+2x_R}{3+2}\\ \\y_Q=\dfrac{3y_P+2y_R}{3+2}

In your case, P(-2,7) and R(1,0), then

x_Q=\dfrac{3\cdot (-2)+2\cdot 1}{3+2}=\dfrac{-4}{5}\\ \\y_Q=\dfrac{3\cdot 7+2\cdot 0}{3+2}=\dfrac{21}{5}

Which ordered pair is a solution of the equation? -x-4y=-10 A: (3,2) B: (-3,3) C: Both D: Neither
Marina CMI [18]

Answer:

D

Step-by-step explanation:

we let that,

(3,2)=(x,y)

given the equation that,

x-4y=10

so,we substitute the values of (x,y)=(3,2)it become

3-4(2)=-5

and test another coordinates(-3,3)

-3-4(3)=-15

botha answers doesn't give 10 as the answer so the answer is D(neither)
