What is the slope of the line that passes through points (3,2) and (4,5)? *
Answer:3over1
Step-by-step explanation:
Answer:
3
Explanation:
The formula for the slope of a line is
[tex]\frac{ y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
In this case, the y2 would be 5 and the y1 would be 2
so the numerator would be 3.
The x2 would be 4 and the x1 would be 3 so the denominator would be 1.
The answer is [tex]\frac{3}{1} = 3[/tex]
Simplify each expression using an exponent rule learned in class. [tex](\frac{y}{x} )^{4}[/tex]
Hey there! I'm happy to help!
If you raise a fraction to an exponent, you apply that exponent to the numerator and the denominator. This would give us [tex]\frac{y^4}{x^4}[/tex].
Have a wonderful day! :D
Since the exponent is outside the fraction, you apply the exponent to both the numerator and denominator.
(y/x)^4 = y^4/x^4
Best of Luck!
On a long-distance biking trip, annike started biking at 7 a.M., and her average speed was 11 miles per hour. Celia started at 8 a.M., and her average speed was 14 miles per hour
Answer:
3.67 hours
Step-by-step explanation:
Speed is the ratio of distance to time, it is given by the formula:
Speed = Distance / time
For annike her average speed was 11 miles per hour and she started at 7 am.
At 8 am (time = 1 hr i.e 7 am to 8 am) the distance she would have covered is given as:
11 miles/hr = distance / 1 hr
Distance = 11 miles per hr × 1 hr = 11 miles
After 8 am, the distance traveled at time t is:
11 = distance/t
distance = 11t
Total distance = 11t + 11
For Celia she started at 8 am at 14 miles per hour, at time t, the distance traveled is:
14 = distance/t
Distance = 14t
Given that both bikers traveled the same distance, hence:
14t = 11t + 11
3t = 11
t = 11/3
t = 3.67 hours
Ben's favorite deli says the average serving time is 12 minutes. Ben notices that the wait time at the deli varies at different times of day, before and after noon. His observations when the wait time is as advertised can be represented by the equation 2|x − 2| − 12 = 0. Solve for the times when the serving time is as advertised, relative to noon.
Answer:
Step-by-step explanation:
Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;
Note that the modulus of the function |x-2| will return both positive and negative value.
For the positive value of |x-2|;
2|x − 2| − 12 = 0
2(x − 2) − 12 = 0
open the parenthesis
2x-4 - 12 = 0
2x - 16 = 0
add 16 to both sides
2x-16+16 = 0+16
2x = 16
x = 16/2
x = 8
For the negative value of |x-2|;
2|x − 2| − 12 = 0
-2(x − 2) − 12 = 0
open the parenthesis
-2x+4 - 12 = 0
-2x - 8 = 0
add 8 to both sides
-2x-8+8 = 0+8
-2x = 8
x = -8/2
x = -4
Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes

Writing What is the slope of the line which goes through the points (-3,-11) and (1,1)
The slope of the line is (Type an integer or a simplified fraction.)
Answer:
3
Step-by-step explanation:
[tex]m=\frac{rise}{run}=\frac{1+11}{1+3}=\frac{12}{4}=\boxed{3}[/tex]
The slope of the line would be 3.
Hope this helps.
Answer:
Slope = 3
Step-by-step explanation:
Let (x1,y1) = (-3,-11) and (x2,y2) = (1,1)
Slope = y2-y1/(x2-x1)
1-(-11)/(1-(-3) = 12/4 = 3
The recipe of a certain type of rice calls for 2:3 ratio to water . If you need to make 5 cups of rice , how much water should you use ?
Answer:
7 and 1/2 cups of water.
Step-by-step explanation:
Every 2 cups of rice, you need three cups of water. You make this equation, [tex]\frac{2}{3} \frac{5}{y}[/tex] and do cross multiplication to get 2y=15, divide that by two and end up with 7 1/2 cups of water.

What is the measure of AngleDCF?
Three lines extend from point C. The space between line C D and C E is 75 degrees. The space between lines C E and C F is 54 degrees.
The measure of AngleDCF is
degrees.
Answer:
129°
Step-by-step explanation:
∠DCE = 75
∠ECF = 54
∠DCF = ∠DCE + ∠ECF
= 75 + 54
= 129°
Answer:
129

Expand:
[tex]4x-5=2* \:2x+2* \:1[/tex]
[tex]4x-5=4x+2[/tex]
Add 5 to both sides:
[tex]4x-5+5=4x+2+5[/tex]
[tex]4x=4x+7[/tex]
Subtract 4x from both sides:
[tex]4x-4x=4x+7-4x[/tex]

expand (x-5)(x+2)(x+7)
Answer:
x³ + 4x² - 31x - 70
Step-by-step explanation:
Step 1: Expand (x - 5) and (x + 2)
(x - 5)(x + 2) = x² + 2x - 5x - 10 = x² - 3x - 10
Step 2: Expand (x² - 3x - 10) and (x + 7)
(x² - 3x - 10)(x + 7) = x³ - 3x² - 10x + 7x² - 21x - 70 = x³ + 4x² - 31x - 70

Is √3,600 rational or irrational? Please help asap.
Answer:
[tex]\sqrt{3600}[/tex] is rational
Step-by-step explanation:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The answer of square root of 3600 is 60 which is not a decimal or an irrational number and therefore it's rational
