Eric cell phone service cost $40.00 a month for unlimited calls he also pays $0.02 for each text message he send. whichbis equation represents the total cost C in dollars for a month when eric send ť text message

Given :

Service cost , c = $40.

Amount paid for each message , m = $0.02 .

To Find :

Equation represents the total cost C in dollars for a month when eric send t text message.

Solution :

Let , total cost be C .

It is an linear equation with slope equal to 0.02 and y-intercept equal to 40.

So ,

Hence, this is the required solution.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
