Determine the values of k for which the equation has no solution

Mathematics
1 answer:
Naddik [55]3 years ago
5 0

To solve this, we would need to figure out the values of k for which an absolute value is negative. From basics, you should know that an absolute value is always greater than or equal to 0.

If we rearrange this equation a little bit, we get,

|2x+7|\leq 5+k

So 5+k <em>cannot </em>be negative. So,

5+k\geq 0\\k\geq -5

For this to <em>have </em>a solution, k needs to be greater than or equal to -5.

For <em>no solution</em>, k is less than -5. So, values of k which will make the equation to <em>not </em>have any solution is k.

ANSWER:  k

Leven purple marbles, seven orange marbles and two pink marbles are in a bag. What is the probability of selecting a purple marb
likoan [24]

Answer:

The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%

Step-by-step explanation:

First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .

The angle between the ground at the top of a flag pole is 25o when the observer is at point A. The observer walks 10 m directly
gladu [14]

Answer:

12.4967 m

≈  12.5 m

Step-by-step explanation:

From the solution diagram attached, to find /AB/, we apply sine rule:

AB/Sin 140° =AD/Sin 15°

AB = 10/Sin 15° x Sin 140°

     = 24.8372 m

To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:

Sin ∅  =  BC/AB

Sin 25° =   BC/ 24.8372

BC = 24.8372 Sin 25°

    =  10.4967 m

The height of the pole =  BC + 2.0

                                      =  10.4967 + 2.0

                                      = 12.4967

                                     ≈  12.5 m

Graph this equation on the coordinate plane.
Liula [17]
Select any two x and plug it into the equation to get the corresponding y:

I’ll do 1 and 2 for example.
x = 1
y = -2(1) + 4
y = -2 + 4
y = 2

So we have the point (1, 2)


x = 2
y = -2(2) + 4
y = -4 + 4
y = 0
We have the point (0, 2)

Plot (1, 2) and (0, 2) and draw the line that goes through both.
