What is the effect on the graph of f(x) if it is changed to f(x) + 7 and f(x + 7)?Linear, quadratic and exponential

faust18 [17]

I cant tell you everything, but changing it to f(x)+7 means you move the graph UP 7 on the y-axis. And f(x+7) means you move the graph DOWN 7 on the x-axis because it is 'counter intuitive' when inside the bracket. so you basically do the opposite.

Determine the measure of an angle whose measure is 17 times that of its complement.

Iteru [2.4K]

Complement angles are angles which when added, the sum is equal to 90 degrees. In this case, we let angle one as x while angle 2 is represented by 17x. The equation then is equal to x + 17x = 90 ; 18x = 90. x from the equation is equal to 5. Hence teh angles are 5 degrees and 85 degrees

Consider all of the four-digit numbers that can be formed using the digits 1, 2, 3, and 4 when no digit is used twice. What is t

Hoochie [10]

Answer:

Option B

Step-by-step explanation:

Given: all the four-digit numbers are formed using the digits 1, 2, 3, and 4 such that no digit is used twice

To find: probability that number chosen lies between 2000 and 3000

Solution:

Probability refers to chances of occurring of some event.

Total number of numbers formed using digits 1, 2, 3, and 4 = $4\times 3\times 2\times 1=24$

Numbers between 2000 and 3000 start with 2. So, first digit is fixed as 2. For remaining three digits, possibilities are 4, 3, 1

So, total number of numbers lie between 2000 and 3000 = $3\times 2\times 1=6$

Probability that number chosen lies between 2000 and 3000 = total number of numbers lie between 2000 and 3000/Total number of numbers formed using digits 1, 2, 3, and 4 = 6/24 = 1/4

In percentage form, Probability that number chosen lies between 2000 and 3000 = $\frac{1}{4}(100)=25\%$

What are the x- and y- coordinates of point P on the directed line segment from K to J such that P is 3/5 the length of the line

const2013 [10]

Answer:

option A)

(40, 96)

Step-by-step explanation:

Given that,

The coordinates of point K and J are

K(160,120)

J(-40,80)

x1 = 160

x2 = -40

y1 = 120

y2 = 80

P is (3/5) the line of the line segment from K to J

So, KP = (3/5) KJ and JP = (2/5) KJ

OR we will divide the length of KJ with the ratio 3 : 2 from K

m : n

3 : 2

m = 3

n = 2

by using this formula and putting values in it

xp = (m/m+n)(x2-x1) + x1

yp = (m/m+n)(y2-y1) + y1

xp = (3/3+2) (-40-160) + 160

yp = (3/3+2) (80-120) + 120

xp = 40

yp = 96
