Answer:
0.2636 hrs
Step-by-step explanation:
Number of kilometers from Sam's house to highway = 7.5 km
Average speed traveled on highway = 55km/hr
Which equation can be solved to find t, the time in hours Sam travels on the highway to reach a farm 22 kilometers away from his house?
Time traveled (t) to reach a farm 22 kilometers from his house :
t = time in hours Sam travels on the high way:
Distance from highway to farm = (Distance of farm from Sam's house - distance from Sam's house to highway)
22km - 7.5km = 14.5km
Speed of travel on highway = 55kmph
Travel time = distance / speed
Travel time = 14.5km / 55km/hr
Travel time = 0.2636 hrs
i need help with 2: simplify algebraic expressions
Answer:
a). 11x²
b). 6x + 5y
c). -4x - 20
Step-by-step explanation:
a). 8x² + 3x²
When you collect the like terms (8 and 3 are the coefficients of x²) and add them together, you get 11x²
b). 3x - 5x + y + 4y + 8x
Start by placing the like terms next to each other.
3x - 5x + 8x + y + 4y
Then add/subtract
6x + 5y
c). -4(x + 7) + 8
First, you have to expand the expression and then simplify.
-4x - 28 + 8
-4x - 20

The table shows the price for different numbers of chocolate boxes:
Number of Chocolate Boxes Price (in dollars)
2 10
3 15
4 20
5 25
Does this table of numbers represent a proportional relationship? (1 point)
No, because the price of 3 boxes should be $11
No, because the price of 4 boxes should be $40
Yes, because 5 times the price is the number of boxes
Yes, because the price is 5 times the number of boxes
10 point for the question

Write the equation of the line, with the given properties, in slope-intercept form.
Slope = -4, through (7,4)
Answer:
Step-by-step explanation:
Slope-intercept form means the equation should be written in this manner
[tex]y=mx+c[/tex]
where m is the slope and c is the y-intercept
so lets take all the date we have to achieve it.
We have a point (7,4) and slope which is m= -4 we can substitute the slope and point in our equation and find the y-intercept .
[tex]y=mx+c\\4=(-4)(7)+c\\4=-28+c\\32=c[/tex]
so now we have our y-intercept that is c=32
now for the equation to be in the slope-intercept form we need m and c and we have both so just replace these variables with their values.
[tex]y=-4x+32[/tex]

Triangle ABC is translated 2 units up and 4 units to the right and is then rotated 180° to
produce the image triangle A'B'C'. What are the coordinates of B' in the resulting figure?
Answer:
[tex]B' = (7,-6)[/tex]
Step-by-step explanation:
From the attachment, we have that:
[tex]A = (1,8)[/tex]
[tex]B = (-3,4)[/tex]
[tex]C = (4,-2)[/tex]
Required
Determine B'
Taking the translation one at a time:
2 units up
This implies, we add 2 to the y value of the function
[tex]B = (-3,4)[/tex] becomes
[tex]B' = (-3, 4 + 2)[/tex]
[tex]B' = (-3, 6)[/tex]
4 units right
This implies, we subtract 4 to the x value of the function
[tex]B' = (-3, 6)[/tex] becomes
[tex]B' = (-3 - 4,6)[/tex]
[tex]B' = (-7,6)[/tex]
180 degrees rotation
Here; B'(x,y) becomes B'(-x,-y)
So, the initial coordinates [tex]B' = (-7,6)[/tex]
becomes
[tex]B' = (-(-7),-6)[/tex]
[tex]B' = (7,-6)[/tex]
Hence:
The final coordinates of B' is [tex]B' = (7,-6)[/tex]

Given the equation: 3x-4y=24
Find two solutions to the equation
Write your answers as coordinates
Answer:
Step-by-step explanation:
we can write this equation into a function to easily plug in values and find solutions
[tex]3x - 4y = 24\\4y = 3x - 24\\y = \frac{3x}{4} - 6[/tex]
now we can plug in any x value and find an appropriate y value
e.g.
x = 0, y = -6 (0, -6)
x = 4, y = -3 (4, -3) [tex]\frac{3(4)}{4} - 6 = 3 - 6 = -3[/tex]
x = 16, y = 6 (16, 6) [tex]\frac{3*16}{4} - 6 = 12 - 6 = 6[/tex]
etc
How do you know which way the rotation is going in geometry? For example clockwise or counterclockwise.
Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8
Answer:
y = -4/3x + 3
Step-by-step explanation:
3x − 4y = −8
-4y = -3x - 8
y = 3/4x + 2
slope m = 3/4
perpendicular version of it is opposite inverse: -4/3
y-intercept through point (0, 3):
y = mx + b
3 = -4/3(0) + b
b = 3
Use the perpendicular slope with b from above to form new perpendicular equation of line:
y = mx + b
y = -4/3x + 3

Answer:
1 - a. addition
2 - c. constant
3. - b. coefficient
4. - d variable
Step-by-step explanation:
+ is the universal sign for addition
11 is a number which is always constant
here w doesn't have a constant value and can be any number. hence it is a variable
the 2 in the 2w is a number which multiplies with the variable w. the value of 2w varies with the value of w. So here 2 is the coefficient of the w in 2w

The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. For a random sample of 162 adult males, the mean pulse rate is 69.6 bpm and the standard deviation is 11.3 bpm. Find the value of the test statistic.
Answer:
0.6758
Step-by-step explanation:
Given That:
Population Mean pulse rate (μ) = 69
Sample size (n) = 162
Sample mean (m) = 69.6
standard deviation (σ) = 11.3
Value of test statistic :
(m - μ) / (σ/√n)
(69.6 - 69) / (11.3 / √162)
0.6 / 0.8878118
= 0.6758

a(b+c) - d = e, for a
Answer:
a = [tex]\frac{e+d}{b+c}[/tex]
Step-by-step explanation:
To isolate the a, the first thing I would do is bring the d to the other side of the equation, remember to switch the sign. This would give me a(b+c) = e+d. Next, in order to get rid of the (b+c), bring it to the other side by dividing since it is attached to the a variable by multiplication. This leaves me with a = e+d / b+c. Make sure not to distribute, this would duplicate your a variable.
