what is the value of the function when x = 0? ​

Answers

Answer:

f(0) = -2.

Step-by-step explanation:

This question pertains to the y-intercept. By definition, the y-intercept is the point on the graph where it crosses the y-axis, and has coordinates, (0, b). It is also the value of y when x = 0.  Looking at the graph, the point where the line crosses the y-axis is (0, -2). The y-coordinate is the y-intercept, b.

Therefore, the value of the function when x = 0 is: f(0) = -2.

Step-by-step explanation:

The number of nickels 61 nickels

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of dimes be = x

Let the number of nickels be = y

So , total number of coins = 100

x + y = 100   be equation (1)

And , the total amount = $ 6.95

The cost of one dime = $ 0.10

The cost of one nickel = $ 0.05

So , total cost = 0.10x + 0.05y = 6.95   be equation (2)

Now , on simplifying equation (1) and equation (2) , we get

x + y = 100

10x + 5y = 695   be equation (3)

Divide equation (3) by 5 , we get

2x + y = 139   be equation (4)

Now , Subtracting equation (1) from equation (4) , we get

x = 39

Therefore , the number of dimes is 39 dimes

Substituting the value of x in equation (1) , we get

x + y = 100

y + 39 = 100

Subtract 39 on both sides of the equation , we get

y = 61

Therefore , the number of nickels is 61 nickels

Hence ,

The number of dimes is 39 dimes

The number of nickels 61 nickels

Write the equation in standard form.
y+ 7= -3/2 (x+1)

Answers

Answer:

2y + 3x = -17

Step-by-step explanation:

standard form is Ax + By = C

first step is to distribute -3/2 among 'x' and then by 1 to get:

-3/2x - 3/2

you now have y + 7 = -3/2x - 3/2

we want to get the -3/2x term on the same side as 'y' and get 7 from the right side to the left side

we want to add 3/2x to the left side of the equation because it is being subtracted:

y + 3.2x + 7 = -3/2

now we want to subtract 7 to the right side because it is currently being added:

y + 3/2x = -7 3/2

we can convert -7 3/2 to be -17/2

we now can eliminate the denominator of 2 in the 'x' term by multiplying each term by 2 to get:

2(y + 3/2x) = -17/2(2)

distribute and simplify to get:

2y + 3x = -17

An angle measures 64.8° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer: angle 1 = 56  and angle 2 = 124

Step-by-step explanation:

Supplementary angle equal 180 degrees

   let X be angle 1 and X +68 be angle 2

    x + x + 68 = 180

     2x + 68 = 180

          - 68     - 68

      2x = 112

        x = 56

        x + 68 = 56 + 68 = 124
