Answer:

The answer would be r = 2

Step-by-step explanation:

Answer:

r=2

Step-by-step explanation:

r² - 4r + 4 = 0​

r^2-(2+2)r+4=0

r^2-2r-2r+4=0

r(r-2)-2(r-2)=0

(r-2)(r-2)=0

r=2,2

Step-by-step explanation:

y2- y1/x2-x1

-1-5/6-2

-6/8

The required slope of AB is -3/4 which passes through points  A(-2, 5) and B(6.-1).

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

To determine the slope of AB: A(-2, 5) and B(6.-1)

Given,

We have been given that two points are A(-2, 5) and B(6.-1)

Let

x₁ = -2, y₁ = 5

x₂ = 6, y₂ = -1

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute values in the formula

The slope of AB = (-1 - 5)/(6 - (-2))

The slope of AB = (-6)/(6 + 2)

The slope of AB = -6/8

Therefore, the required slope of AB is -3/4.

Answer:

35.8

Step-by-step explanation:

                [tex]\frac{340.1}{9.5}[/tex]  = 358

 We know that our answer can never be greater than 358 since the dividend

is 340.1 and the divisor is 9.5;

  Also,

  Both values are to one decimal places and we can use this to solve the problem;

  9 can divide 340 in about 37 place with a remainder of 7,

    So, it is appropriate to make the solution 35.8

Answer:

The number of minutes is 10minutes

Step-by-step explanation:

  Step one:

Given that the first minute of a call cost $2.30 and

each additional minute is $0.20.

let the number of minutes be x

and the total cost be y

the total cost  for the situation is modeled as

y=mx+c-----equation of a line

   Step two:

given that y=4.3, we can solve for the totals cost as

by substituting we have

4.3=0.2x+2.3

4.3-2.3=0.2x

2=0.2x

x=2/0.2

x=10

The number of minutes is 10minutes

Answer:

n = 12

Step-by-step explanation:

84 / 7 = 12

May I have brainliest please? :)

Answer:

84 is 7 x n.

n = 84 ÷ 7

n = 12

Step-by-step explanation:

You can solve the problem by using algebraic expressions in looking for the value of n.

Let n be the no. of families in City B that have a dog.

City A is 7 times as many families with a dog than City B. You can express this as: City A = 7 x n

Since you know that City A has 84 families owning a dog. Then you can express this as: 84 is 7 x n or 84 = 7 x n.

Let's get the value of n.

84 = 7 x n

n = [tex]\frac{84}{7}[/tex] or n = 84 ÷ 7

n = 12

There are 12 families in City B that have a dog.

Answer:

t=-14

Step-by-step explanation:

subtract 17 from each side

Answer:

t = -14

Step-by-step explanation:

to find out the answer, you need to get t by itself and to do that you subtract 17 from both sides. On the left side, it cancels out and on the right, 3-17 is -14 so t would equal -14

Answer:

Step-by-step explanation:

Answer:

0.05357142

Step-by-step explanation:

Answer: $9.75.

Step-by-step explanation:

Given: Cost per stamp  = 39 cents

since 1 dollar = 100 cent , so 1 cent = 0.01 dollar

So,  Cost per stamp  = $0.39

Total stamps = 25

Cost of 25 stamps = (Cost per stamp)  x (Cost per stamp)

=$0.39 x 25

= $9.75

Hence, the price  for the sheet of stamps = $9.75.

Answer:

its 10 with the remainder of 38

Step-by-step explanation:

The result of the division is remainder = 38 and quotient = 10

Division is the opposite of multiplying. When we know a multiplication fact, we can find a division fact: Example: 3 × 5 = 15, so 15 / 5 = 3. Also, 15 / 3 = 5.

Given that, 708 divided by 67

When dividing 708 by 67 will get 10 as quotient and 38 remainder

Hence, the result of the division is remainder = 38 and quotient = 10
