Mathematics
1 answer:
alukav5142 [94]3 years ago
8 0

Answer:

k = 13

Step-by-step explanation:

The sum of the angles is 180 since they form a straight line

4k-7 + 90 + 3k+6 = 180

Combine like terms

7k+89=180

Subtract 89 from each side

7k+89-89 = 180-89

7k =91

Divide each side by 7

7k/7 = 91/7

k = 13

Martina creates the graph of function g by applying a transformation to function f.
MrRa [10]

Answer:

B.a vertical shift of 9 units up

Step-by-step explanation:

Given f(x) = 4x-2\\g(x) = 4x+7

g (x) = f (x) + k

It means shifting f (x)\ k unit vertically.

Now, we will find the value of k for the given function

g(x) = 4x+7\\\\add\ 2\ and\ subtract\ 2\\\\g(x) = 4x+7+2-2\\g(x) = 4x-2+9\\\\We\ have\ f(x)=4x-2\\\So,\ g(x)=f(x)+9

k=9

Hence, vertical shift of 9 units.

Need help with middle two questions... I’ll give points
nignag [31]

Answer:

ok sorry i could not put this into a formula im have to go but i will show you a really easy way.

Step-by-step explanation:

for number 1 i got (7,-1)

This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.

The correct way for doing number 1 is using the distance formula i believe but im running out of time

for the second one i got  (3, -1/2)

we do this by using the midpoint formula.

The first picture is for number one and the second for number 2

if you have any questions feel free to ask in the comments

Softa [21]

Answer:

0.006369

Step-by-step explanation:

Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.

By mere guessing p = probability for a right answer = 1/5 =0.20

There are two outcomes and each question is independent of the other.

X no of questions right is Bin (10,0.20)

the probability that the student will pass the test

= prob of getting more than 60%

=P(X\geq 6)

=0.006369
