What is the value of x in the equation 3x – 4y = 65, when y = 4? <br> the answer is x=27

Olenka [21]

What is the value of x in the equation 3x-4y=65 when y=4?

Simple...plug n chug..

3x-4(4)=65

3x-16=65

Now, isolate the variable, x....

3x-16=65
+16 +16

3x=81

Now, divide,

$\frac{3x}{3} = \frac{81}{3}$

x=27.

Thus, your answer.

Which represents the solution(s) of the system of equations, y + 4 = x2 and y-x=2? Determine the solution set by

Sergeu [11.5K]

Answer:

The points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

Step-by-step explanation:

Here, the given equations are: $y + 4 = x^{2} , y -x = 2$

Now checking for the given points:

(a) (-2, 0)

Here, $y + 4 = 0 + 4 = 4 = (-2)^{2} = x^{2} \\y- x = 0 -(-2) = 2 = RHS$

Hence, (-2, 0) is the solution of the given equations.

b) Checking for (2,0), as (-2, 0) is a solution as shown above

Here, $y + 4 = 0 + 4 = 4 = (2)^{2} = x^{2} \\y- x = 0 + (-2) = -2 \neq 2(RHS)$

Hence, (2, 0) is NOT the solution of the given equations.

c) Checking for (3,5), as (-2, 0) is a solution as shown above

Here, $y + 4 = 5 + 4 = 9 = (3)^{2} = x^{2} \\y- x = 5 -3 = 2 - (RHS)$

Hence, (3,5), is the solution of the given equations.

Hence, the points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

What is the median of the data set {23 , 16 , 19 , 17 , 15 , 19 , 17 , 24 }

Yuki888 [10]

Answer:

7; 19; 24; 10; 17; 21; 6; 22; 5; 9

Arrange: 5; 5; 6; 7; 9; 10; 17; 19; 21; 22; 24

( 5+5+6+7+9+10+17+19+21+22+24 ) / 11

Mean = 145 / 11

Mean = 13,18

Mode = 5

(5 is the only value that appears most often)

Median = 10
