Step-by-step explanation:

When u plug in the values in C u get the ranges

Answer:

(14,3)

Step-by-step explanation:

2x + y = 19

x - y = 11

-2(x - y) = -2(11)

-2x + 2y = -22

-2x + 2y = -22 + 2x + y = 19

3y = -3

y = 3

-------------------------------------------------

x - y = 11

x - 3 = 11

x = 11 + 3

x = 14

The graph is in the picture below

Step-by-step explanation:

Answer:

When a number 'x' is divided by another number 'y', the number 'x' is divided into 'y' number of equal parts.  

If 'y' divides 'x' without any remainder, then 'x' is evenly divisible by 'y'.

Step-by-step explanation:

(i)  When 21 is divided by 3, 21 is divided into three equal parts and the value of each part is 7.  

(ii)  When we divide 35 by 5, we get

7 + 7 + 7 + 7 + 7

(iii)  When 35 is divided by 5, 35 is divided into 5 equal parts and the value of each part is 7. And also, there is nothing left over in 35.

So, 35 is evenly divisible by 5.

(iv)  When 35 is divided by 4, we get

8 + 8 + 8 + 8 + 3

There is remainder 5, when 35 is divided by 3.

So, 35 is not evenly divisible by 4.

Property 2 :  

When a number is divided by another number, the division algorithm is, the sum of product of quotient & divisor and the remainder is equal to dividend.

Answer:

(a) Index finger

(b) Ring finger

(c) Index finger

Step-by-step explanation:

Taking thumb as standard for the question.

Thumb series 1 , 9 , 17 ,25, 33......

general term for this

a(n) = 1 + (n-1)8

      = 1 + 8n -8

       = 8n -7

(a) For 1 to 10

     8n -7 = 10

     8n = 16+1 (remainder)

so the thumb is for 9 and the next is index finger.

10th = index finger.

(b) for 1 to 100

    8n - 7 = 100

      8n= 107

     107 = 13x 8 + 3(remainder)

so the third finger from thumb is Ring finger

100th = Ring finger

(c) 8n - 7 = 1000

   8n = 1007      

 1007= 125x8 +7 (remainder)

so the 7th finger next to thumb is Index finger

1000th = index finger

Answer:

see explanation

Step-by-step explanation:

Using the product/ difference identity

sinxsiny = [tex]\frac{1}{2}[/tex] [ cos(x - y) - cos(x + y) ]

Consider the left side

2sin([tex]\frac{\pi }{4}[/tex] + α)sin([tex]\frac{\pi }{4}[/tex] - α )

= cos[[tex]\frac{\pi }{4}[/tex] + α - [tex]\frac{\pi }{4}[/tex] + α ] - cos [[tex]\frac{\pi }{4}[/tex] + α + [tex]\frac{\pi }{4}[/tex] - α ]

= cos2α - cos[tex]\frac{\pi }{2}[/tex]

= cos2α - 0

= cos2α = right side , thus proven

Answer:

Please check the graph below.

Step-by-step explanation:

Given the function

[tex]y\:=\:x^2\:+\:6x\:+\:5[/tex]

Axis interception points of the function

x-axis interception points can be computed by setting y=0

[tex]x^2+6x+5=0[/tex]

[tex]\left(x+1\right)\left(x+5\right)=0[/tex]

Using the zero factor principle

if  [tex]\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

[tex]x+1=0\quad \mathrm{or}\quad \:x+5=0[/tex]

[tex]x=-1,\:x=-5[/tex]

Hence,

x-axis interception points are: (-1, 0), (-5, 0)

y-axis interception points can be computed by setting x=0

[tex]x^2+6x+5=0[/tex]

[tex]y\:=\:\left(0\right)^2\:+\:6\left(0\right)\:+\:5[/tex]

[tex]y=0+0+5[/tex]

[tex]y=5[/tex]

Hence,

y-axis interception points are: (0, 5)

From the graph, it is clear that at (-3, -4) the parabola changes direction, hence (-3, -4) it the "vertex".

Also at the point x=-2, then y is = -3

So, all the points are labeled and the graph is attached below.

Answer:

130 skittles

Step-by-step explanation:

Since Sarah is the 2 side of the ratio, i divided her side of it by 2 so i could multiply by 5 to get the full bag. 3:2 = 78:52 skittles

Answer:

16

Step-by-step explanation:

Given expression:

   f(x) = 4 [tex](\frac{1}{2} )^{-x}[/tex]

  Now we are to find f(2);

 To find f(2) we are to substitute 2 for any place where we find x;

  f(2)  = 4 [tex](\frac{1}{2} )^{-2}[/tex]

  f(2)  = 4 x [tex]\frac{1}{(\frac{1}{2})^{2} }[/tex]  

 f(2) = 4 x [tex]\frac{1}{\frac{1}{4} }[/tex]  

f(2) = 4 x 4 = 16

i did this question on my test, from reading the graph, i am almost certain this is the answer. correct me if i am wrong!

Answer:

B)

Step-by-step explanation:

B because the  Stock XYZ shows the best performance. The scale of Stock ABC makes the graph appear to be rising more slowly.

Answer:

B

Step-by-step explanation:

If you look at the graph/chart, it starts at 1,000, so half of that is 500, so you go down to 500, and go straight down to see the number of time under it (In this case, is 1 minute) so you know it is one minute

Answer:

I'm answering this question so 1 the other person can get brainliest and 2 so I can say:

HIIIIIIIIIIIIIIIIIIIIIII!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The sum of two complementary angles is 90 degrees.

Angle A  +  Angle B = 90

Let Angle B = X

5x + 2 + x = 90

Combine like terms:

6x +2 = 90

Subtract 2 from both sides:

6x = 88

Divide both sides by 6:

x = 88/6

x = 14.67

Angle B = 14.67 degrees ( rounded to the nearest hundredth)

Answer:

the third one!

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

cos(x) = x³

f(x) = cos (x) - x³

f(x) is continuous on the interval (0, 1)

when;

f(0) = cos (0) - (0)

f(0) = 1 - 0

f(0) = 1 > 0

f(1)  = cos (1) - 1³

f(1) = 0.5403 - 1

f(1) = -0.4597

f(1) = - 0.46

f(1) = - 0.46 < 0

Since, 1 > 0 > -0.46, thus there is a number ''c" in (0,1)

such that f(c) = 0

By applying the Intermediate Value Theorem, there is a root of the equation in the interval (0,1)

b) Given that:

The interval length = 0.01; this implies that it is 0.005 length from its root.

f(0.865) = 0.0014

f(0.87) = - 0.013

The solution to the interval lies between 0.865 , 0.87 by using a calculator at length 0.01.

Answer:

Answer:

543.2 miles

Step-by-step explanation:

Input the given value of x into the equation and solve for y:

y = -67.9x + 679

y = -67.9(2) + 679

y = -135.8 + 679

y = 543.2

The total distance in miles after 2 hours is 543.2 miles.

Answer:

y = -4x + 31

Step-by-step explanation:

y = mx + b

y = -4x + b

-5 = -4(9) + b

-5 = -36 + b

b = 31

Answer:

$-83.75

Step-by-step explanation:

She won't have any more money to spend

Multiply $36.75 by 5

That would be $183.75

Subtract 183.75 from 100

-83.75

So Helen wouldn't have anything left to spend.

She would actually be in debt because she used more than $100
