What is the slope of the line that passes through the points (−4,4) and
(−6,6)? Write your answer in simplest form.

Answer:

r = -2

Step-by-step explanation:

7(3r - 1) - (r + 5) = -52 distribute (the - sign too)

21r - 7 + -r - 5 = -52 add/ subtract like terms

20r - 12 = -52 subtract -12 and added to -52

     +12      +12

20r = -40 divide by 20

20r/20 = -40/20

r = -2

Answer:

10 times greater

Step-by-step explanation:

the 5 in 520 is in the  hundreds place value

The 5 in 50 is in the tens place value

50 *10 = 500

From units to tens-------------Multiply by 10 (2*10=20)

From tens to  hundreds-------Multiply by 10  (20*10=200)

From hundreds to thousands----Multiply by 10 (200*10=2,000)

And so on

The value of 5 in 520 is in the hundreds place, so it equates to 500. Conversely, the 5 in 750 is in the tens place, meaning it equals 50. Thus, the 5 in 520 is 10 times greater than the 5 in 750.

This question pertains to the place value in numbers, an essential mathematical concept. In the number 520, the digit 5 is in the hundreds place, which means its value is 5*100 = 500. On the contrary, in the number 750, the digit 5 is in the tens place, hence, it's value is 5*10=50.

Therefore, to find out how many times the value of the 5 in 520 is greater than the value of the 5 in 750, divide the value of the 5 in 520 (which is 500) by the value of the 5 in 750 (which is 50). So, 500 divided by 50 equals 10. This reveals that the value of the digit 5 in 520 is 10 times greater than the value of the digit 5 in 750.

Answer:

113

$1.13

Step-by-step explanation:

22x + 3 when x = 5 is written 22(5) + 3

You multiply first, 22(5) = 110 + 3 = 113

a nickel is worth .05 so you mulitply .05 x 22 which gets you 1.1 and 3 pennies is .03 and when you add the two together you get $1.13

Answer: The value of 22x+3 is 113. The amount of money that equals 22 nickels and 3 pennies. That answer is also 1113.

Step-by-step explanation:

For the first problem u want to basically do 22 times 5 and that gives you 110. Then after doing that u want to do 110+3 which equals 113.

For the second one since nickels equal 5 cents u want to do 22•5 which gives you 110 and then you do 110+3 and that gives you 113.

Answer:

442

Step-by-step explanation:

170/5 (to find per hour)

34*13 = 442

Answer:

The rate per hour is 34 bagels per hour. They can bake 442 bagels in 13 hours.

Step-by-step explanation:

Rate per hour:

170/5= 34

You do this because you want to find the amount of bagels they can bake in 1 hour, which is found through 170/5.

Bagels in 13 hours:

34*13= 442

You use the unit rate established, 34 bagels per hour, and multiply it by 13 hours, 13*34.

Answer:

10 calories were burned for each minute of jogging  and  10 calories were burned for each minute of cycling.

Step-by-step explanation:

Let be "j" the amount of calories Shelly burned for each minute of jogging and "c" the amount of calories Shelly burned for each minute of cycling.

Set up a system of equations:

[tex]\left \{ {{10j+20c=300} \atop {20j+10c=300}} \right.[/tex]

You can apply the Elimination method: multiply the first equation by -2, then add the equations and  solve for "c":

[tex]\left \{ {{-20j-40c=-600} \atop {20j+10c=300}} \right.\\...............................\\-30c-300\\\\c=10[/tex]

Now, substitute the value of "c" into any original equation and solve for "j":

[tex]10j+20(10)=300\\\\10j=300-200\\\\10j=100\\\\j=10[/tex]

Step-by-step explanation:

Devin brought his snail collection to school. He has 10 snails.

the smallest number of snails in the tank is 0 and the greatest number of snails in the tank is 10. Also the number of snails in each tank must be a whole number (Devin cannot put half of the snail into the tank). There are 11 whole numbers between 0 and 10.

Hence,  all 11 possibilities to divide snails into two tanks are:

[tex]\begin{array}{cc}\text{Tank 1}&\text{Tank 2}\\ \\0&10\\1&9\\2&8\\3&7\\4&6\\5&5\\6&4\\7&3\\8&2\\9&1\\10&0\end{array}[/tex]

The sums of two numbers in each row must be exactly 10 as the total number of snails Devin has.

Answer:

Step-by-step explanation:

Any [tex]b\neq 0[/tex] raised to the 0-th power will give 1. So [tex]a=3[/tex]

Once you know that, from the passing through (2,48) you get:

[tex] 48=3b^2\\ 16=b^2 b=4 [/tex]

Notice that,even if -4 satisfies the condition, exponential functions are defined only and only if the base is positive and not equal to 1. (if the base was 1, you'd get an horizontal line, and with a negative base the function starts losing meaning in the real plane in a series of points.

To write the exponential function in y = ab^x form, we use the given y-intercept and a point on the graph to find the values of 'a' and 'b'.

To write the exponential function in y = ab^x form, we need to find the values of a and b.
Based on the information given, we know that the y-intercept is (0,3), which means that when x = 0, y = 3.
So, we have the equation 3 = ab^0, which simplifies to a = 3. Now, using the point (2,48), we can substitute the values of a and x to find the value of b. We get 48 = 3b^2, which simplifies to 16 = b^2. Taking the square root, we find that b = 4. Therefore, the exponential function is y = 3 * 4^x.

Step-by-step explanation:

Mike has two part time jobs.

Job 1: Ice-cream store

Number of hours worked= 8.5 hours

Payment per hour=$10.55

Job 2: Movie theater

Number of hours worked=7 hours

Payment per hour=$13.85

1. Earnings per week before taxes

⇒For job 1 will be; the product of hours worked and hourly payments

= 8.5×$10.55 =$89.68

⇒For job 2 will be;

=7×$13.85=$96.95

Total=$89.68+$96.95=$186.63

2.  Calculate amount taken as tax

    Find 22% of the amount earned

   = 22/100 * 186.63 =$41.06

  Remaining amount after tax will be;

   =$186.63-$41.06=$145.57

12(f + 2)

Step-by-step explanation:

12F + 24 = 12 (f + 2)

Answer:

It is an algebraic expression that has an answer which can be determined by multiplying a known value of variable F by 2, and adding 24 to the outcome.

Step-by-step explanation:

2F + 24 is an algebraic expression which implies that if a variable F is multiplied by 2 and 24 is added to it, there would be a certain outcome. This expression has no answer unless the value of F is known.

By factorisation, the expression can be re-written as:

                  2F + 24 =  2 (F + 12)

which would give the same answer as the initial expression.

Therefore, the given algebraic expression represents a value which can be determined by multiplying a known value of variable F by 2, and adding 24 to the outcome.

Answer:

b. There are horizontal and vertical asymptotes

Step-by-step explanation:

The graph is a hyperbola with asymptotes of x=0 and y=0

The correct options regarding the graph of y = 1/x are:

b. There are horizontal and vertical asymptotes.

c. The graph intersects the x-axis in two places.

a. The domain of y = 1/x is all real numbers except x = 0 since division by zero is undefined.

b. The graph of y = 1/x has a vertical asymptote at x = 0, which means the function approaches infinity as x approaches 0 from the left side and approaches negative infinity as x approaches 0 from the right side.

There is no horizontal asymptote because the function does not approach a specific y-value as x approaches positive or negative infinity.

c. The graph intersects the x-axis in two places: once for positive x-values and once for negative x-values.

The x-intercepts occur when y = 0, which happens when x = 1 and x = -1.

d. The range of y = 1/x is y ≠ 0 since division by zero is undefined. The function can take on positive and negative values as x approaches positive or negative infinity, respectively.

Therefore, the range is y < 0 or y > 0, depending on the chosen interval.
