<u>Answer</u>

y = 5x +25


<u>Explanation</u>

To get the equation of a line, first get the slope of the line.

Slope = (change in y)/(change in x)

          = (60-30)/(7-1)

          = 30/6

            = 5

Now use one point in the line (4,45) and a general point (x,y).

Slope = (change in y)/(change in x)

    5 = (y - 45)/(x - 4)

    5(x - 4) = (y - 45)

  5x - 20 = y - 45

y = 5x -20 + 45

y = 5x + 25

This question is worth 20 points if someone answers it! ​
Nostrana [21]

The maximum number of tourists in the third week will be maximum in the numberville city.The solution of f(x)=h(x) will be x(5,2).

<h3>What are equations?</h3>

The equation is actually a relationship between the numbers and the variables.

To calculate the number of the tourists in the third week we will put the value 3 in every function:

f(x)=x^2+5x+10=(3)^2+(3\times 3)+10=29\\\\\\g(x)=3^x=3^3=27\\\\\\h(x)=10x=10\times 3=30

So we can see that the function third h(x) numberville city is having a maximum number of tourists.

The solution of f(x)=h(x) will be calculated as:

x^2-3x+10=10x\\\\\\x^2-7x+10=0\\\\\\x^2-5x-2x+10=0\\\\\\x(x-5)-2(x-5)=0\\\\\\x=5,2

Hence the solution of f(x)=h(x) will be x(5,2).

Find the indicated angle measures:
Lera25 [3.4K]

Answer:

Angle 1: 55 degrees
Angle 2: 55 degrees
Angle 3: 70 degrees

Step-by-step explanation:

<u>Finding angle 1:</u> We know that in a triangle, all three angles must add up to 180 degrees. In the triangle on the left, 2 of the angle measures are already given to us. Therefore, we can simply do 180 - 40 - 85, thus the measure of angle 1 is 55 degrees.
<u>Finding angle 2:</u> We know that opposite angles are congruent. Therefore, angle 2 and angle 1 have the same measure.
<u>Finding angle 3:</u> Using the same thought process as we used when finding the measure of angle 1, we can subtract the other 2 angles. 180 - 55 - 55 is equal to 70.

Which statements are true? Check all that apply. The square root of a positive number greater than 1 is less than the number. Th
Korolek [52]

Answer: The true statements are:-

1.The square root of a positive number greater than 1 is less than the number.

as 2<4

2.The square root of a positive number less than 1 is between 0 and 1.

as square root of 0.04 is 0.2 which lie between 0 and 1.

Step-by-step explanation:

2.The square root of a positive number is always less than half of the number itself . It is not true always , for example the number is 4 then the square root of 4 =2 and it is not less than half of 4=2  .

3.The square root of a positive number less than 1 is less than the number.

It is not true ,as 0.04=(0.2)^2

⇒ 0.2 is the square root of the number and is not less than the number.

4 .The square root of a perfect square is not a whole number. It is not true, as 4 is a perfect square and its square root is 2 which is a whole number.
