Answer:

k = 4

Step-by-step explanation:

Distribute First: 2 ( k- 5)

2k - 10

So now it is:

2k - 10 + 3k = k + 6

Combine Like Terms (CLT):

2k - 10 + 3k = k + 6

5k - 10= k + 6

Inverse operation:

(K = 1k)

5k = k + 16

-k     -k

4k = 16

________

4         4

k = 4

choose the equation in point slope form for the line that is perpendicular to the given line and passing through the given point
alexdok [17]

We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) .

The equation and the point is;

y=\frac{2}{3}x+9,(5,6)

We know that for two lines to be perpendicular, the product of their slopes should be -1.

Therefore, the slope of the perpendicular should be;

m=-\frac{1}{(\frac{2}{3})}=-\frac{3}{2}

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is;

y-y_1=m(x-x_{1_{}})

Inserting all values, we have,

y-6=.-\frac{3}{2}(x-5)

That is the final answer.

Jerald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in s
Snezhnost [94]

Answer. First option: t > 6.25


Solution:

Height (in feet): h=-16t^2+729

For which interval of time is h less than 104 feet above the ground?

h < 104

Replacing h for -16t^2+729

-16t^2+729 < 104

Solving for h: Subtracting 729 both sides of the inequality:

-16t^2+729-729 < 104-729

-16t^2 < -625

Multiplying the inequality by -1:

(-1)(-16t^2 < -625)

16t^2 > 625

Dividing both sides of the inequality by 16:

16t^2/16 > 625/16

t^2 > 39.0625

Replacing t^2 by [ Absolute value (t) ]^2:

[ Absolute value (t) ]^2 > 39.0625

Square root both sides of the inequality:

sqrt { [ Absolute value (t) ]^2 } > sqrt (39.0625)

Absolute value (t) > 6.25

t < -6.25 or t > 6.25, but t can not be negative, then the solution is:

t > 6.25

PLEASE HELP!!! NO BOTS!! solve for x​
Vesnalui [34]

Answer:

/2=1.41

/5=2.24

(a)^2+(b)^2=(c)^2

(1.41)^2+(b)^2=(2.24)^2

2+(b)^2=5

(b)^2=5-2

(b)^2=3

b=/3 or 1.73

Step-by-step explanation:

for a triangle, a missing value of the side can be found using pythagorean theorem which is (a)^2+(b)^2=(c)^2

replace it with the given value.

*note:(c)^2 should be the hypotenuse

inverse of +ve is -ve

inverse of square is square root
