What is the value of X in the equation 8X - 2y=48,when y=4

Mathematics

Anni [7]3 years ago

Answer:

x = 7.

Step-by-step explanation:

The given equation is  

8x-2y=48

We need to find the value of x, when y=4.

Substitute y=4 in the given equation and then solve for x.

8x-2(4)=48

8x-8=48

Add 8 on both sides.

8x=48+8

8x=56

Divide both sides by 8.

x=\dfrac{56}{8}

x=7

Therefore, the value of x is 7, when y=4.

Answer:

X=7

Step-by-step explanation:

8x-2y=48

8x-2(4)=48

8x-8=48

8(7)-8=48

56-8=48

The graph represents the cost of a subscription to a newspaper. A coordinate plane showing Ferry Ride Cost with Number of Person
allochka39001 [22]

Answer:

The constant of variation is $1.50

Step-by-step explanation:

Given

Point 1 (1,2)

Point 2 (5,8)

Required

Constant of Variation

Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.

Having said that,

the constant variation can be solved by calculating the gradient of the graph;

The gradient is often represented by m and is calculated as thus

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1, y_1) = (1,2)\\(x_2, y_2) = (5,8)

By substituting values for x1,x2,y1 and y2; the gradient becomes

m = \frac{8 - 2}{5 - 1}

m = \frac{6}{4}

m = \frac{3}{2}

m = 1.50

Hence, the constant of variation is $1.50
