Answer: (0,0) or y=0
In order to find the y-intercept, we need to find the point that crosses the y-axis. To find that x=0 or (0,y)
When x=0, y=0 on the graph since there are no transformations.

Which expression represents the difference (6b+9) – (7b — 4)?
Answer:
there arent any options but this is what i got
− b + 13
Step-by-step explanation:
Final answer:
The difference expression (6b+9) – (7b — 4) simplifies to -b + 13 after distributing the negative sign and combining like terms.
Explanation:
The expression representing the difference (6b+9) – (7b — 4) is obtained through the subtraction of the second polynomial from the first. To perform the subtraction, one must distribute the negative sign to the terms within the second polynomial, which flips the signs of the terms inside the parentheses. Therefore, the subtraction becomes:
(6b + 9) + (-7b + 4)
Now, combine like terms:
Combine the b terms: 6b - 7b = -1b
Combine the constant terms: 9 + 4 = 13
After combining like terms, the final simplified expression is -1b + 13 or simply -b + 13.
Frank averages a speed of 19 miles per hour during his bike race. The race is 60 miles long.
Answer:
3 hours and 16 minutes or 3.16 for Frank to finish the race
Step-by-step explanation:
60 miles long Frank is going 19 miles an hour
60 divided by 19 3.157 rounded up 3.16
Using the distance and speed, we calculate the time it takes for Frank to complete the bike race. He averages a speed of 19 miles per hour for a 60-mile race, which means it will take him approximately 3.16 hours to finish.
Explanation:This question is about solving a typical problem in math - specifically, calculating time with information on distance and speed. To figure out how long it would take Frank to finish the 60-mile bike race, we use the formula Time = Distance / Speed. Given that Frank averages a speed of 19 miles an hour, we divide the total distance (60 miles) by his average speed (19 mph).
So, 60/19 ≈ 3.16. That means Frank will take approximately 3.16 hour to complete the bike race.

and the y-intercept of the line of best fit on the scatter plot?
Answer:
The y intercept is 80 and the line of the best fit is -3/5
Step-by-step explanation:
The y intercept of the line of best fit is 80 miles with a slope of -0.6 mile per minute
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, the y intercept is 80 miles. The line passes through (0, 80) and (100, 20), hence:
slope = (20 - 80) / (100 - 0) = -0.6 mile per minute

5 days and she remembers the last day's pulse was 58 and all the others were the same. Write and solve an equation to find what her pulse was on all the other days. Justify your answer by showing your steps. Put in Simple equation
Answer:
63
Step-by-step explanation:
She finds her average resting heart rate to be 62 after 5 days.
That means, average of the 5 heart rate pulse=62
If the last day was 58 and all the other days were the same.
Let x be her pulse on the other days,
Then,
[tex]Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63[/tex]
Her pulse on all the other days is 63.

Answer:
100 Cos 40° + 100 Sin 40° ≈ 141 yards
Step-by-step explanation:
From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle
This means that;
Cos 40° = x/100
x = 100 Cos 40°
Sin 40° = y/100
y = 100 Sin 40°
Therefore, total distance walked = x + y
" = 100 Cos 40° + 100 Sin 40° ≈ 141 yards

The height of a trapezoid is 6 in. and it’s area is 72 in to the 2nd power. One base of the trapezoid is 6 inches longer than the other base. What are the lengths of the bases? Complete the explanation of how you found your answer.
One base is __ inches for one of the bases and __ inches for the other base.
Use the formula for the area of a trapezoid. Substitute 72 for A and 6 for h and simplify the equation to find __ = (b1 + b2). Use guess and check to find two numbers that add to __ with one number 6 more than the other to get __ inches for one of the bases and __ inches for the other base.
Given:
The height of the given trapezoid = 6 in
The area of the trapezoid = 72 in²
Also given, one base of the trapezoid is 6 inches longer than the other base
To find the lengths of the bases.
Formula
The area of the trapezoid is
[tex]A=\frac{1}{2} (b_{1} +b_{2} )h[/tex]
where, h be the height of the trapezoid
[tex]b_{1}[/tex] be the shorter base
[tex]b_{2}[/tex] be the longer base
As per the given problem,
[tex]b_{2}=b_{1} +6[/tex]
Now,
Putting, A=72, [tex]b_{2}=b_{1}+6[/tex] and h=6 we get,
[tex]\frac{1}{2} (b_{1} +b_{1}+6)(6) = 72[/tex]
or, [tex]b_{1}+b_{1}+6 = \frac{(72)(2)}{6}[/tex]
or, [tex]2b_{1}+6 = 24[/tex]
or, [tex]2b_{1}=24-6[/tex]
or, [tex]b_{1}= \frac{18}{2}[/tex]
or, [tex]b_{1}=9[/tex]
So,
The shorter base is 9 in and the other base is = (6+9) = 15 in
Hence,
One base is 9 inches for one of the bases and 15 inches for the other base.
9. Mrs. Kenny teaches a ceramics class. She finds
that she has of a pound of clay for a project. The
project requires of a pound. How many projects
can Mrs. Kenny complete without running out of clay?
To find how many projects can be completed, divide the total amount of clay Mrs. Kenny has by the amount of clay required for each project. However, the question seems to be missing the values for the total amount of clay and the amount required per project.
Explanation:Mrs. Kenny is teaching a ceramics class where she uses clay for her projects. As stated, it seems there is a portion of the question omitted which is the number of pounds of clay Mrs. Kenny has and the amount required for each project. Ideally, the number of projects Mrs. Kenny can complete is determined by dividing the total weight of the clay she has by the weight of clay required for each project. For instance, if Mrs. Kenny has 3 pounds of clay and each project requires 1/2 pound of clay, she would be able to complete 6 projects (3 divided by 1/2 = 6).

What is the perimeter, in units, of the model?
О64х + 24
О46х + 25
O32х + 12
050x +11
Given:
Given that the model of the house.
The house is made up of two composite figures triangle and rectangle.
The two sides of the triangle are 6x - 4 units each.
The length of the rectangle is 14x + 13.
The width of the rectangle is 12x + 3.
We need to determine the perimeter of the house.
Perimeter:
The perimeter of the house can be determined by adding all the sides of the house.
Thus, we have;
[tex]Perimeter=2(6x -4 )+2(12x+3)+(14x+13)[/tex]
Simplifying the terms, we get;
[tex]Perimeter=12x -8+24x+6+14x+13[/tex]
Adding the like terms, we have;
[tex]Perimeter=50x+11[/tex]
Thus, the perimeter of the house is 50x + 11 units.

Nancy's spaghetti and meatballs recipe calls for 2 cloves of garlic the recipe makes 8 servings how much garlic is in each serving
Answer:
1/4 clove
Step-by-step explanation:
Each serving of Nancy's spaghetti and meatballs recipe contains a quarter (or 0.25) of a garlic clove.
Explanation:In the given scenario, Nancy's spaghetti and meatballs recipe asks for 2 cloves of garlic and yields 8 servings. Hence, to find out the amount of garlic in each serving, we need to divide the total cloves of garlic by the number of servings. Hence,
Garlic per serving = Total garlic / Number of servings
Here's how to do the math:
Garlic per serving = 2 cloves / 8 servings = 0.25 cloves per serving
So, there is 0.25 or a quarter of a garlic clove in each serving of Nancy's spaghetti and meatballs recipe.

Please help!! In radians, what is the period of the function y = .5cos5x
pi/5
(3pi)/2
(2pi)/5
pi/2
Answer:
(2pi)/5
Step-by-step explanation:
The cosine function cos(x) has a period of 2*pi.
If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:
5x = 2*pi
x = 2*pi/5
The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.
