Solving Two Step Equations
3(x + 4) - 5 = 2x + 4
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:
Step-by-step explanation:
While on vacation in Washington DC, the cab ride for the Dulles airport to the hotel is 15 miles. The
total cost of the cab ride was $25.50. The cabbie charges $1.50 per mile for the entire trip.
A. Write an equation to that can be used to determine how much a cab ride would cost anywhere in Washington DC.
B. What is the flat rate of the cab ride?
C. How much does it cost to travel 7 miles in a cab?
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

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
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]

A student has an allowance of $20 each week. He wants to buy lunch at school for $3.50 every day, Monday - Friday. Does the student have enough money to buy lunch?
Why or why not?
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

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
Which inequality represents this graph?
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.

3) if the cost of 1 pen is Rs.10, find the cost of 5 pen
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.
