Answer:
m = 1/2
Step-by-step explanation:
Use two points on the line given.
(0 , 2) & (-4 , 0)
You are solving for the slope. The slope formula:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-4 , 0)
(x₂ , y₂) = (0 , 2)
Plug in the corresponding numbers to the corresponding variables:
m = (2 - 0)/(0 - (-4))
Simplify:
m = (2)/( 0 - (-4))
m = (2)/(0 + 4)
m = 2/4
Simplify the slope. Divide the common factor 2 from both the numerator and denominator:
m = (2/4)/(2/2) = 1/2
1/2 is your slope.

solve for v 2(3v+8)=70
Answers
Answer:v = 9
Step-by-step explanation:
Simplifying
2(3v + 8) = 70
Reorder the terms:
2(8 + 3v) = 70
(8 * 2 + 3v * 2) = 70
(16 + 6v) = 70
Solving
16 + 6v = 70
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 6v = 70 + -16
Combine like terms: 16 + -16 = 0
0 + 6v = 70 + -16
6v = 70 + -16
Combine like terms: 70 + -16 = 54
6v = 54
Divide each side by '6'.
v = 9
Answer: the answer is 9
Step-by-step explanation:
1. open the bracket by multiplying: 2(3v+8)=70
6v+16=70
2. take the 16 over the equals sign. note:(the plus sign in front of the 16 changes to a minus sign.)
6v=70-16
6v=54
3. divide both sides by 6
6v/6=54/6
final answer: v=9

Answer: [tex]2x^{2} - 10x -28[/tex]
Step-by-step explanation:
We know that f(x) = 2x +4 and g(x) = x -7 so to find f(g(x)) multiply them.
(2x + 4)(x-7) Apply the distributive property twice
2x(x-7)

Fabienne rolls a ball 72 inches across the floor. This is 9 times the distance that Olivier rolls his ball across the floor. Let n represent the number of inches Olivier rolls his ball.
How many inches does Olivier roll his ball?
Select each equation that can be used to solve this problem.
Answers
Answer:
8 inches
Step-by-step explanation:
Oliver rolls his ball 1/9th of the distance Fabienne rolls his, so just divide 72 by 9 to get your answer.
Answer:
Oliver rolls his ball 8 inches.
the equation that was used to solve this was : 9n = 72 inches.
Step-by-step explanation:
Since the 72 inches was nine times the distance that Oliver rolled his ball, it means that the unknown number (n), was multiplied by 9 to get Fabienne's inches. So, 9n = 72.
divide both sides by the number next to the unknown to get (n), the number of inches that Oliver rolled his ball.... which is 8.
Which of the following pairs could be reasonable approximations for the diameter and circumference of a circle? 18 inches and 57 inches 3 centimeters and 28 centimeters 33 meters and 80 meters
Answers
Answer:
18 inches and 57 inches
Step-by-step explanation:
The diameter and the circumference of a circle are proportionate to each other.
The circumference of a circle will always be the diameter times [tex]\pi[/tex]. We know this because the circumference of a circle is represented as
[tex]2 \pi r[/tex]
Since the diameter is twice the radius, we multiply the radius by 2 - there's already a [tex]\cdot 2[/tex] in this equation, so [tex]c = \pi d[/tex].
1st option: [tex]18\cdot3.14 = 56.52[/tex], this is close to 57 so it's reasonable.
2nd option: [tex]3\cdot 3.14 = 9.42[/tex], this isn't close to 28 at all.
3rd option: [tex]33 \cdot 3.14 = 103.62[/tex], this isn't close to 80 at all.
So the 1st option is reasonable.
Hope this helped!
Answer:
First option: 18 inches diameter, 57 inches circumference
Step-by-step explanation:
Circumference of a circle is...
2 * radius * pi
We can approximate pi (3.14159...) to 3.
So the circumference of a circle is approx.
2 * radius * 3
We know the diameter of a circle is 2 times the radius...
diameter = 2 * radius
Thus, the circumference of a circle is approximately...
diameter * 3
First option:
Diameter 18, circumference 57
Let's try our approximation
18 * 3 = 54
We see that 57 is pretty close and is a reasonable approximation.
Second option:
Diameter 3, circumference 28
3 * 3 = 9
Not even close to 28.
Third option:
Diameter 33, circumference 80
3 * 33 = 99
Closer, but much further off than our first option.

We are subtracting a negative so it becomes a positive.
- 3 + 5 + 1
-3 + 6 = 3
Step-by-step explanation:
Remember: We have to know the PEMDAS rule: Parenthesis first, then Exponents, then mulitplication/division, and then addition/subraction.
Since -1 is in parenthesis, we solve for that first. 5-(-1) is equal to 5+1, which is equal to 6. Then, we solve from left to right: -3 + 6, which is 3.

The sum of two consecutive integers is 345. What are the integers? need help with it
Answers
Answer:
hi there ☺️
Here we will use algebra to find three consecutive integers whose sum is 345. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 345. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 345
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 345
3X + 3 = 345
3X + 3 - 3 = 345 - 3
3X = 342
3X/3 = 342/3
X = 114
Which means that the first number is 114, the second number is 114 + 1 and the third number is 114 + 2. Therefore, three consecutive integers that add up to 345 are 114, 115, and 116.
114 + 115 + 116 = 345
We know our answer is correct because 114 + 115 + 116 equals 345 as displayed above.

What type of parent function is this? What is the domain and range of this function? write it in interval notation
Answers
Answer:
See below.
Step-by-step explanation:
This is a parabola. Therefore, it is a quadratic parent function. The quadratic parent function is:
[tex]f(x)=x^2[/tex]
The domain of the parent quadratic function is all real numbers.
The range of the parent quadratic function is all y-values greater than or equal to 0. From the graph, we can see that the graph never goes below 0.
So, the domain in interval notation is:
[tex](-\infty,\infty)[/tex]
And the range in interval notation is:
[tex][0,\infty)[/tex]
This is interpreted as all values greater than or equal to 0.

The amount of water in a bottle is reduced by 15% to 119 milliliters. How much water was originally in the bottle? ________ ml
Answers
Explanation:
let x be the original amount of water
x - 15% = 119
But x = 100% because it’s the original
=> 100% - 15% = 119ml
85% = 119ml
Find the amount of water in 15%:
85% = 119
15% = y
=> 85/15 = 119/y
Cross multiply:
85y = 15 x 119
85y = 1785
y = 1785/85
y = 21
But y = 15% therefore, 15% = 21ml
Back to our equation:
x - 15% = 119ml
x - 21ml = 119ml
x = (119 + 21)ml
x = 140ml
Therefore, the original amount of water is 140ml

So to find the answer, we would use the equation 32+4x=56 where as x represents the amount of strawberries Sameer ate. Now to solve for x
56-32=4x
24=4x
now divide 4 from bboth sides of the equation getting:
x=6

A used automobile dealership recently reduced the price of a used compact car by 6%. If the price of the car before discount was $18 800, find the discount and the new price?
Answers
Answer:
The discount = $1,128
New price = $17,672
Step-by-step explanation:
Price of car before discount = $18,800
Discount given = 6% of price of car
Discount value in dollars = 6% of $18,800 = 6/100*$18,800 = $1,128
Thus, the discount is $1,128
New price = Price of car before discount - discount = $18,800- $1,128
New price = $17,672

$14 to $29
Original number/start = $14
End number = $29
Increase = $29 - $14 = $15
% increase = Increase ÷ Original Number × 100
Substitute in known values
% increase = 15 ÷ 14 × 100
Divide
% increase = 1.07 × 100
Multiply
% increase = 107%
The percentage increase is 107%
Hope this helps :)
Answer:
107%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
new number = 29; old number = 14
percent change = (29 - 14)/14 * 100%
percent change = 15/14 * 100%
percent change = 107%

30 minutes
23 minutes
58 minutes
22.5 minutes
21 minutes
Answers
Answer:
21 minutes
Step-by-step explanation:
Given the following :
Taking CITY STREET:
Time taken to drive to nearest bowling alley = 45 minutes = 45/60 = 0.75 hours
Speed of travel = 30 miles per hour
Taking FREEWAY:
speed of travel = 65miles per hour
If the distance to bowling alley is the same along both routes, The time taken along FREEWAY will be :
.
Distance to bowling alley taking city center :
Speed = distance / time
30 mph = distance / 0.75 hour
Distance = 30 × 0. 75 = 22.5 miles
Since distance is the same :
Time taken along FREEWAY :
Time taken = distance / speed
Time taken = 22.5 / 65 = 0.3461538 hour
Converting to minutes :
0.3461538 × 60 = 20.769 minutes
= 21 minutes ( to the nearest minute)
