Answer:

35mins

Step-by-step explanation:

Can you hear me now cost function: y=0.15x+50.75

24 Hour Calls cost function: y=0.9x+24.5

Set two equations equal to each other because we want to find the time (x value) that make the cost  (y-value) equal

0.15x+50.75=0.9x+24.5

0.75x=26.25

x=35mins

Answer:

-2/5

Step-by-step explanation:

2x - 11 = 4x - 13 - 7x

2x - 11 = -3x - 13

2x - 11 + 3x = -13

5x - 11 = -13

5x=-13+11

5x=-2

X= - 2/5

You multiply 2 by d then and then by 7 making 2d+14

Answer:

-1

Step-by-step explanation:

2(y−6)+3=4y−7

2y−12+3=4y−7

2y-12+12+3=4y-7+12

2y+3=4y+5

2y+3-3=4y+5-3

2y-4y=4y-4y+2

-2y=2

-2y/-2=2/-2

y=-1

The value of y in the given algebraic expression when simplified is; y = -1

We are given the algebraic expression;

2(y − 6) + 3 = 4y − 7

Expand the bracket to get;

2y − 12 + 3 = 4y − 7

Use addition property of equality to add 12 to both sides to get;

2y - 12 + 12 + 3 = 4y - 7 + 12

2y + 3 = 4y + 5

Subtract 3 from both sides to get;

2y + 3 - 3 = 4y + 5 - 3

2y = 4y + 2

4y - 2y = -2

2y = -2

y = -2/2

y = -1

Answer:

-3/2

Step-by-step explanation:

To find the slope of the line, you need to use the slope formula.

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\[/tex]

Plug in the given points into the equation and solve for m.

[tex]m=\frac{-5 -1 }{6 -2 } \\\\m=\frac{-6}{4} \\m=-\frac{3}{2}\\[/tex]

The slope is -3/2.

A linear equation should have points that graph in a straight line.

Step-by-step explanation:

I hope it help !

A linear equation should have points that graph in a straight line.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function is a function in which the slope remains constant.

Since a straight line has a constant slope thus it will represent the straight line.

Hence "A linear equation should have points that graph in a straight line".

 3/4, 4/6, 5/8, 2/3, 6/10

Step-by-step explanation:

The five fractions that provide a range of values between 1/2 and 7/8 are 5/8, 3/4, 11/16, 2/3, and 13/16.

Here are five fractions that lie between 1/2 and 7/8:

5/8: This fraction is greater than 1/2 but less than 7/8. It can be obtained by dividing 5 by 8.

3/4: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 3 by 4.

11/16: This fraction is closer to 1/2 and slightly less than 7/8. It can be obtained by dividing 11 by 16.

2/3: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 2 by 3.

13/16: This fraction is closer to 7/8 and greater than 1/2. It can be obtained by dividing 13 by 16.

These five fractions provide a range of values between 1/2 and 7/8. They demonstrate different proportions and can be used in various contexts where a fraction between 1/2 and 7/8 is required, such as measurement, comparison, or estimation.

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118

Answer:
