The approximate distance between point p and q are 5.1 so the answer is D.
Elodia [21]3 years ago
5 0

Answer:

(D) 5.1 units

Step-by-step explanation:

From the given graph, we get the two points P and Q that are:

P=(-3,-4) and Q=(2,-3)

Thus, the approximate distance between the points P and Q is given as:

|PQ|=\sqrt{(-3+4)^4+(2+3)^2}

|PQ|=\sqrt{(1)^2+(5)^2}

|PQ|=\sqrt{1+25}

|PQ|=\sqrt{26}

|PQ|=5.1 units

Therefore, the approximate distance between the points P and Q is 5.1 units.

Hence, option (D) is correct.

Describe the nature of the roots for the equation<br> 49x2– 28x +4 = 0
Zepler [3.9K]

Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

Point (18, 0)

Point (10, -5)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{-5-0}{10-18}
  2. Subtract:                              m=\frac{-5}{-8}

Suppose x=7 is a solution to the equation 4x-2(x+a)=8 how can you find the value of a that make the equation true
marta [7]

Answer:

a = 3

Step-by-step explanation:

Since x = 7 is a solution, substitute x = 7 into the equation and solve for a

4(7) - 2(7 + a) = 8 , that is

28 - 2(7 + a) = 8 ( subtract 28 from both sides )

- 2(7 + a) = - 20 ( divide both sides by - 2 )

7 + a = 10 ( subtract 7 from both sides )

a = 3
