y=3x−7 Complete the missing value in the solution to the equation. (1,_)

Answer:k = 2/3

Step-by-step explanation:

When a variable y directly relates to another variable x, we can say:

y=kx

Given the equation, we can say

3y=2x

y= 2x/3

Putting the value of y from above discussion

kx = 2x/3

x is being cancelled on both sides of equation

k= 2/3

Answer:

k = 2/3

Answer:

23º = x

Step-by-step explanation:

One straight line is ALWAYS 180º

(called a linear pair)

So your equation is

157º + x = 180

subtract x on both sides

and you get

23º

That is a question about angles.

The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.

So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:

[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]

Therefore, the missing angle is 23°.

I hope I've helped. :D

Answer:

19.9%

Step-by-step explanation:

39.8/200 = 0.199 (move decimal two times)

19.9%

or you can just see what number get 200 to 100, which is by dividing by 2. What you do to the bottom you do to the top so 39.8/200 (divide both sides by 2)  = 19.9/100

which is 19.9%.

Answer:

-2 < 12

Step-by-step explanation:

12 is bigger than -2.

By applying the definition of logarithm, you have

\log_x(64) = 3 \iff x^3 = 64logx(64)=3⟺x3=64

So, if you consider the cubic root of both sides, you have

x = \sqrt[3]{64} = 4x=364=4

2x + 2 + x

Step-by-step explanation:

Answer:

A) 4900

B) How far above she is before she starts hiking/the distance she is from the canyon floor.

Step-by-step explanation:

Since it's linear, it will follow the formula y=mx+c.

We can sub in the values to get:

3500=m(1)+c → 3500-m=c

2100=m(2)+c → 2100 = 2m+c

Sub '3500-m' in for c:

2100=2m+3500-m

m= -1400

c=3500-m=3500-(-1400)=3500+1400=4900

∴equation is: y= -1400x+4900

To find the initial value, ie when the number of hours = 0, we sub in zero for x:

y = -1400(0) + 4900

PART A ANS: 4900

PART B ANS: Since the number of hours passed is zero, the value represents how far above she is before she starts hiking/the distance she is from the canyon floor.

Answer:

[tex]d = -\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]6d-\dfrac{11}2=2d-\dfrac{13}{2}[/tex]

Required

Solve for d

[tex]6d-\dfrac{11}2=2d-\dfrac{13}{2}[/tex]

Collect Like Terms

[tex]-2d + 6d=-\dfrac{13}{2}+\dfrac{11}{2}[/tex]

[tex]4d=-\dfrac{13}{2}+\dfrac{11}{2}[/tex]

Take LCM

[tex]4d=\dfrac{-13+11}{2}[/tex]

[tex]4d=\dfrac{-2}{2}[/tex]

[tex]4d = -1[/tex]

Make d the subject

[tex]d = -\dfrac{1}{4}[/tex]

Find x

The theorem that applies to this question is the theorem of external angles. And it translates to:

[tex]11x +2 = 58 + 5x + 10[/tex]

Collect Like Terms

[tex]11x -5x = 58 + 10-2[/tex]

[tex]11x -5x = 66[/tex]

[tex]6x = 66[/tex]

Divide through by 6

[tex]\frac{6x}{6} = \frac{66}{6}[/tex]

[tex]x = \frac{66}{6}[/tex]

[tex]x = 11[/tex]

Answer:

The image of the point is (8, 4)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)

Let us solve the question

∵ The point is (2, 1)

∴ x = 2 and y = 1

∵ The point dilated by a scale factor of 4 centered at the origin

∴ k = 4

→ By using the rule above multiply each coordinate of the point by 4

∵ The image of the point is (kx, ky)

∵ kx = 4 × 2

∴ kx = 8

∵ ky = 4 × 1

∴ ky = 4

∴ The image of the point is (8, 4)

X = 6

because 8 - 2 = 6

Answer:

the red skittles be 44 and yellow skittles be 17

Step-by-step explanation:

The computation of the number of each color are in the bowl is as follows;

Let us assume the red skittles be y

And, the yellow skittles be x

The first equation is

x + y = 61

And, the second equation is

y = 2x + 10

Now put the second equation in the first equation

x + 2x + 10 = 61

3x = 51

x = 51 ÷ 3

= 17

And, y = 2 (17) + 10

= 34 + 10

= 44

Hence, the red skittles be 44 and yellow skittles be 17

Answer:

20.25

Step-by-step explanation:

i think its asking for the long side

the pythagorean theorem states that in a right triangle a^2+b^2=c^2

a is 19

b is 7

c is the long side

19^2= 361

6^2= 49

361+49=410

410 =c^2

square root of 410 = ~20.25

Answer:

[tex]hypotenuse = \sqrt{ {19}^{2} + {7}^{2}} \\ = \sqrt{361 + 49} = \sqrt{410} \\ = 20.25[/tex]

20.25 is the right answer.

Given:

The function is

[tex]y=3x[/tex]

Domain of the function is {9, 15, 18, 21, 27}.

To find:

The range of the function.

Solution:

We have,

[tex]y=3x[/tex]

Domain is set of input (x-values) and range is the set of output (y-values).

Domain =  {9, 15, 18, 21, 27}

For x=9,

[tex]y=3(9)=27[/tex]

For x=15,

[tex]y=3(15)=45[/tex]

For x=18,

[tex]y=3(18)=54[/tex]

For x=21,

[tex]y=3(21)=63[/tex]

For x=27,

[tex]y=3(27)=81[/tex]

So, the y-values are 27, 45, 54, 63, 81.

Therefore, the range of the function is {27, 45, 54, 63, 81}.

Note: Options are not in proper form.
