how do you know you have a direct variation in the relationship between two quantities?

Answers

Answer 1
According to Khan academy:

“Say you have y=2x. That is a direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2d to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.”

Hope this helps!

Answers

Answer:

x=67

Step-by-step explanation:

The correct statement is,

(B) f(x) has a greater maximum value than g(x).

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Function f (x) is,

f (x) = - 8x² + 7

Now, First, we determine the maximum point of f(x).

f(x) is at maximum at the point of symmetry, i.e. where x = - b/a

Here, a = -8, b = 0

Hence, x = - 0 / - 8 = 0

So, We get;

f (0) = - 8 x 0 + 7 = 7

Thus,

The maximum point of f(x) is (0,7)

And, The maximum point of g(x) is (2,6)

Therefore, f(x) has a greater maximum value than g(x).

Hence3, The correct option is B.

Molly bought c candy canes. She paid $1.05, including tax, per candy cane. She gave the cashier $10 and received $1.60 in change. How many candy canes did Molly purchase? Please hurry

Answers

Answer:

Number of candy = 8 candy canes.

Step-by-step explanation:

Cost per candy = $1.05

Amount paid = $10

Change received = $1.60

Total cost = amount paid - change received

Substituting into the equation, we have;

Total cost = 10 - 1.6

Total cost = 8.4

To find the number of candy purchased;

Number of candy = total cost/cost per candy

Number of candy = 8.4/1.05

Number of candy = 8 candy canes.

Therefore, Molly purchased 8 candy canes.

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.

Answers

Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

To isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Isolating variables in inequality

Isolation of variables means making the variable the subject of the formula from the given expression.

Given the inequality expression -1/2 w  < 12

To make w the subject of the formula, we will have to multiply both sides by -2 to have;

-1/2 w * -2 >  12 * -2
w > -24

Hence to isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.
