Find the x- and y- intercepts of the
equation 7x + 6y = 42.
Answers
Answer:
x intercept: (6,0) y intercept: (0,7)
Step-by-step explanation:
first is x intercept
7x+6(0)=42
7x=42
x=6
now y intercept
7(0)+6y=42
6y=42
y=7
The x- and y- intercepts of the equation 7x + 6y = 42 will be x intercept: (6,0) y intercept: (0,7)
What is x-intercept of a function?The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function.
The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
The first is x intercept of the equation;
7x + 6y = 42
So, y = 0
7x+6(0)=42
7x=42
x=6
Now y - intercept of the equation;
7(0)+6y = 42
6y = 42
y = 7

A random sample of 26 restaurants was selected from all restaurants listed in Greenwich Village and their Zagat ratings were recorded. Zagat ratings are averages of responses from many diners who rated the restaurants on a scale of 0 to 30 on food, décor, and service. Diners also estimated the total cost of dinner, one drink, and a tip. Suppose that Zagat is interested in whether they can predict the cost of a meal from the Zagat service rating. In that study, the response (dependent) variable is:
Answers
Complete Question
The complete question s shown on the first uploaded image
Answer:
Correct option is B
Step-by-step explanation:
Generally the respond dependent variable can be defined as a variable whose values are dependent on the changes in other variable
Now in this question the respond (dependent) variable is the cost of meal , this because from the question the interest of Zagat is to predict the cost of a meal from the Zagat service rating
So in this case the independent variable is Zagat service rating
While the responds dependent variable is cost of meal
Assume that you have a total of 14 people on the board: 5 out-of-state seniors, 3 in-state seniors, 1 out-of-state non-senior, and 5 in-state non-seniors. University rules require that at least one in-state student and at least one senior hold one of the three offices. Note that if individuals change offices, then a different selection exists. In how many ways can the officers be chosen while still conforming to University rules?
Answers
Answer:
The appropriate solution is "570". The further explanation is given below
Step-by-step explanation:
There's a whole average of 14 committee members of trustees, including 5 out-of-state leaders, 5 in-state senior citizens, 1 out-of-state semi-senior, and 3 semi-senior in-state elderly. Out of those 14 members, 3 members must be chosen. According to the required specifications, the 3 members chosen should also include at least a single in-state member as well as at least 1 longtime leader.We may establish the executive committee in two distinct ways, in compliance with us even. One is about choosing the in-state participant from either the five seniors throughout the state, which follows the university's two requirements. As well as the other option is to choose an in-state participant from either the three non-senior in-state students.The 2nd incarnation should also be chosen from either the 5 out-of-state leaders throughout the second scenario. Across each circumstance, we can determine the multitude of scenarios, and afterward, the amount of the two can provide the maximum range of things the board can indeed be chosen.(1)
Choosing the right 1 member out of 5 seniors throughout the state.
The remaining 2 candidates would be chosen from some of the other 13 committee members within a week of choosing 1 member from either the 5 in-state representatives.
So, throughout this case, the number among approaches p is supplied by:
⇒ [tex]p=5C_1\times 13C_2[/tex]
[tex]=5\times 78[/tex]
[tex]=390[/tex]
(2)
Choosing the right one person of the legislature out of three non-senior members of the state
In this scenario, as already mentioned, the second participant needs to be chosen from the 5 qualified out-of-state citizens. Currently that we would have chosen 2 members out of 14 members in all, the 3rd member should be chosen out of another leftover 12 people.
Therefore, the amount of forms, throughout this case q, seems to be:
⇒ [tex]q=3C_1\times 5C_1\times 12C_1[/tex]
[tex]=3\times 5\times 12[/tex]
[tex]=180[/tex]
So that the total no. of ways will be:
⇒ [tex]p+q[/tex]
⇒ [tex]390+180[/tex]
⇒ [tex]570[/tex]

ΔABC and ΔEFG are similar triangles due to the SAS congruence postulate rule.
What are Similar Triangles?Similar triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
In triangles ΔABC and ΔEFG,
Angle ∠A = Angle ∠E
SideAB/SideEF = SideAC/SideEG
So, ΔABC ~ ΔEFG
Given triangles are similar due to the SAS congruence postulate rule.
SAS or Side-Angle-Side Similarity Criterion,
According to the SAS similarity theorem, If any two of the first triangle's sides are exactly proportional to those of the second triangle, and if the angle created by these two sides of each triangle is equal, then the two triangles must be similar.
Hence, ΔABC and ΔEFG triangles are similar due to the SAS congruence postulate rule.

Bruce earns x dollars
Elliot earns 5 more than 2 times what Bruce earns
E = 5+2x
Rewriting
E = 2x+5
Answer:
3x + 36 for the first question and 2x + 5 for the second question
Step-by-step explanation:
For the first question, you have to calculate the area of the two rectangles separately and then add them together.
3 · x = 3x
3 · 12 = 36
Add your results together and you get 3x + 36
For the second question, we know Elliot has made 5 dollars more than 2 times how much Bruce has made. Bruce has earned x dollars and we are trying to find out how much Elliot earned.
2 times how much Bruce has made can be represented as 2 · x = 2x
Elliot has made 5 dollars more than 2 times how much Bruce has made so you add 5 to your answer
Elliot has made 2x + 5 dollars

Answer:
x = 36 degrees
Step-by-step explanation:
The sum of a triangle's interior angles is 180 degrees.
We know that 2 of the angles measure 90 degrees (right angle) and 54 degrees. Add those together and you get 144. Now all you have to do is subtract 144 from 180 to get
36 degrees.
180 - 90 - 54 = x
Answer:
36
Step-by-step explanation:
The conner shows a thin square. That means it is a 90-degree angle. You know that x is going to be smaller than the 54- degree angle and 90-degree angle. So the angle x will be a smaller number. You would need to subtract 90 from 54. Therefore the answer is 36.

Answers
Levy is painting a miniature model of a World War II tank. His figure uses a 1:72 scale and is 22.5 cm long. The actual tank is 1620 cm long.
To determine the length of the actual tank, we need to scale up the length of the miniature model using the given scale of 1:72.
Let's denote the length of the actual tank as "x".
According to the scale, 1 cm on the miniature model represents 72 cm on the actual tank.
So, we can set up the following proportion:
1 cm (miniature model) / 72 cm (actual tank) = 22.5 cm (miniature model) / x cm (actual tank)
Cross-multiplying and solving for x, we get:
x = (72 cm * 22.5 cm) / 1 cmx = 1620 cm
The actual tank is 1620 cm long.

n = 27/5
n = 5.4
m + n = 7
m = 7 - n
m = 7 - 5.4
m = 1.6
now you have m = 1.6 and n = 5.4

Answer:
m + n = 7 then m = 7 - n

The profit a company makes is its revenue(R) minus its cost(C). For a bicycle shop C=4x+60 and R=14x-0.01^2 where x is the number of items sold. Which expression does not represent the profit in terms of the number of units sold?
Answers
The answer is that the expression "Profit = 10x - 60.0001" does not represent the profit in terms of the number of units sold.
The profit of a business is its income minus its costs. Given that C represents the cost, and R represents revenue, the formula for the profit (P) is given by:P = R - C
Now, let's plug in the values of C and R:P = 14x - 0.01^2 - (4x + 60)We know that 0.01^2 is equal to 0.0001,
therefore:P = 14x - 0.0001 - 4x - 60Simplifying the equation we get:P = 10x - 60.0001
So, the expression that does not represent the profit in terms of the number of units sold is: Profit = 10x - 60.0001
Therefore, the answer is that the expression "Profit = 10x - 60.0001" does not represent the profit in terms of the number of units sold.

e. m<ABE = 67°
How to Find Each Indicated Measure for the Circle?In order to find the indicated measures in the circle, recall that the measure of an inscribed angle is half of the measure of the intercepted arc based on the inscribed angle theorem.
Thus, we have:
a. m<A = 1/2(m(BD))
Substitute:
m<A = 1/2(76)
m<A = 38°
b. m(CE) = 2(m<CBE))
Substitute:
m(CE) = 2(28)
m(CE) = 56°
c. m<C = 1/2(m(BD))
Substitute:
m<C = 1/2(76)
m<C = 38°
d. m<D = 1/2(m(AC))
Substitute:
m<D = 1/2(78)
m<D = 39°
e. m<ABE = 1/2(m(ACE))
m<ABE = 1/2(m(AC) + m(CE))
