Answer:

6

Step-by-step explanation:

first, set up the equation

4x+7 = x+25

solve for x:

4x = x + 18

3x = 18

x = 6

Answer:

Yes

Step-by-step explanation:

Did the math on my calculator on my phone

Answer:

Yes

Step-by-step explanation:

The cost for each meal is 3.50 and there are five days so you would multiply 3.50 by 5 which equals 17.5. So it would cost the students 17.50 each week for the lunch, leaving them 2.50

The equation that can be used to determine the cost of a cab ride is cost = $3 + ($1.50 x miles driven).

The flat rate of the cab ride is $3.

The cost of travelling 7 miles is $13.50.

The total amount that would be spent on the cab ride is a function of the price per mile, the total miles driven and the flat rate.

Total cost = variable rate + flat rate

variable rate = cost per mile x total miles driven

15 x $1.50 = $22.50

Flat rate = total cost - variable rate

$25.50 - $22,50 = $3

The equation to determine the total cost of a cab ride: $3 + $1.50m

Where m is the miles driven.

The cost of travelling 7 miles : 3 + (1.5 x 7) = $13.50

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Simply plug -3 in for x.

-2(-3)^2-7(-3)+6

(-3)^2=9

9*-2= -18

-7*-3=21

-18+21=3

3+6=9

Answer:

f(-3) = 9

Step-by-step explanation:

Here we have a quadratic function in x:  and we want to know the value of this function when x = -3.

Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to                                                    f(-3) = -2(9) + 21 + 6, or

                                                                                    f(-3) = -18 + 27 = 9

Thus, f(-3) = 9

Answer:

answer to the equation is

[tex]y = 2x + 11[/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

first find the slope of the line using the two points

[tex]slope \: m = \frac{y2 - y1}{x2 - x1} = \frac{23 - 5}{6 - ( - 3)} \\ = \frac{18}{9} \\ slope \: m = 2[/tex]

substitute 2 for m and use one of the points for x and y and solve for b

[tex]5 = 2( - 3) + b \\ 5 = - 6 + b \\ 5 + 6 = b \\ b = 11[/tex]

Now that you found b, the y-intercept, you can substitute that into the equation for your line

[tex]y = 2x + 11[/tex]

Answer:

-3=x

Step-by-step explanation:

3(x+4)-5=2x+4

use distributive property to get:

3x+12-5=2x+4

simplify to get:

3x+7=2x+4

subtract 4 from both sides to get:

3x+3=2x

subtract 3x from both sides to  get:

3=-x

multiply both sides by -1 to get your answer:

-3=x

Answer: 5 pens cost Rs.50

Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.

Answer:

Last option, "y is greater than or equal to -1/3 x + 1"

Step-by-step explanation:

y represents any value in the shaded region, and since the region is above the line, that's how you know it's greater than the line. You also know the sign is greater than or equal to (rather than just greater than), because the line on the graph is solid, instead of dotted.

Hope this makes sense :)
