A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
Answer:
0
Step-by-step explanation:
By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.
If line 1 is parallel to line 2, it means their slopes are the same.
So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].
find the value of x PLEASE HELP i’m so lost
x = -5 + 5√3
Step-by-step explanation:
A = ℓ × w
50 = (x + 10) × x
50 = x² + 10x
x² + 10x - 50 = 0
a = 1b = 10c = -50x = [-b ± √(b² - 4ac)] / 2a
x = [-10 ± √(10² - 4(1)(-50))] / 2(1)
x = [-10 ± √(100 - (-200))]/2
x = [-10 ± √300]/2
x = [-10 ± 10√3]/2
x = [-5 ± 5√3]
because x is a unit of length, it is positive
x = -5 + 5√3
The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?
Answer:
134 people
Step-by-step explanation:
80 / .6 = 133.333
Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people

A manufacturer has a monthly fixed cost of $40,000 and a product cost of $8 for each unit produced. The products sells for $12/unit.
Answer:
48,000
Step-by-step explanation:
The cost function by the given data is C(x) = 40,000 + 8x.
We are given that;
Monthly fixed cost = $40,000
The product cost for each unit produced= $8
Now,
The cost function is a function that gives the total cost of producing a certain number of units. The cost function depends on the fixed cost and the variable cost per unit. The fixed cost is the amount of money that the manufacturer has to pay regardless of how many units are produced, such as rent, salaries, utilities, etc. The variable cost per unit is the amount of money that the manufacturer has to pay for each unit produced, such as materials, labor, etc.
In this case, the fixed cost is $40,000 and the variable cost per unit is $8. To find the cost function, we need to add the fixed cost and the product of the variable cost per unit and the number of units.
We can use x to represent the number of units and C(x) to represent the cost function.
Then we have:
C(x) = fixed cost + (variable cost per unit)(number of units)
C(x) = 40,000 + (8)(x)
Therefore, by algebra the answer will be C(x) = 40,000 + 8x.

Juan graphed a line with a slope of -23
How does Juan count the slope from any point on the graph?
a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.
b. From any point on the graph, he counts up 2 then right 3 to end up on the line again
c. From any point on the graph, he counts down 2 then left 3 to end up on the line again.
d. I don't know.
Answer:
a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.
Step-by-step explanation:
The slope is -2/3.
-2/3 = 2/-3
slope = rise/run
rise/run = -2/3
Count down 2 and right 3.
rise/run = 2/-3
Count up 2 and left 3
Answer: a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.

Answer:
The missing side would be 6.
And the area would be 54.
Step-by-step explanation:
The perimeter equals 30, that's the outside of the rectangle. They give you a part of the perimeter, 9ft. So 9ft and there's another 9ft on the bottom line, (because it is equal to the top width) Which equals 18. To get the other sides you need to subtract 18 from the whole perimeter, 30. Which gives you 12. And there's two sides left, so divide by 2, and you have 6 on each side(left and right sides) Perimeter is adding all the sides up.
And the Area formula is Area=Length times Width. Area=9ft×6ft Which equals 54.

5x+3y=-16
-10x-3y=11
Find the solution
Answer: x = 3.2 + 0.6y
Step-by-step explanation: Simplifying
5x + -3y = 16
Solving
5x + -3y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 16 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 16 + 3y
5x = 16 + 3y
Divide each side by '5'.
x = 3.2 + 0.6y
Simplifying
x = 3.2 + 0.6y

What is an algebraic expression for this word phrase?
5 more than the product of 7 and n
5 + 7n
5(7+n)
7(5+n)
5 + 7 + n
Answer:
The value of the algebraic expression when n is given as 6 will be 38.
An algebraic expression is when we use numbers and words in solving a particular mathematical question.
Based on the information given in the question, the expression will be:
= 1 + 7n - 5
Note that the value of n = 6
Therefore, 1 + 7n - 5 will be:
= 1 + 7n - 5
= 1 + 7(6) - 5
= 1 + 42 - 5
= 38
Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.

use estimation to check whether 96.26 is a reasonable solution fot the equation m-62.74=159
Answer:
See below
Step-by-step explanation:
I hope you wrote down the right equation using a minus sign instead of a plus.
Rounding 96.26 off to just 96 and then rounding 62.74 off to 62, you can subtract the two in your head real quick.
96 - 62 = 34
So using this estimation you can see that the answer of 159 is no where near correct.

Find two consecutive even integers such that 4 times the smaller integer is 44 less than 7 times the larger integer
Answer:
let x be the smaller number.
let x + 2 be the larger number.
4 times the smaller number is 2 more than 3 times the larger number.
in equation form, this becomes:
4x = 3 * (x+2) + 2
simplify this to get:
4x = 3x + 6 + 2 which becomes:
4x = 3x + 8
subtract 3x from both sides of this equation to get:
x = 8
this means that x+2 = 10
the smaller number is 8 and the larger number is 10.
4 times the smaller number is equal to 32.
3 times the larger number + 2 is equal to 32.
requirements of the problem check out ok, so the solution is good.
the smaller number is 8.
the larger number is 10.

Answer:
Domain: 0 <= x <= 6
Range: 10 <= x <= 22
Step-by-step explanation:
There is no minimum to the number of cups she can purchase, thus x > 0 or x >= 1. The maximum amount she can purchase is x = 6 or x <= 6, thus 0 <= x <= 6. Plugging these two values into the function we get a range of 10 <= x <= 22.
