PLEASE help me. I am stuck on this question for a long time.

Answer:

+12

Step-by-step explanation:

1. distribute the negative 5 to 2y and negative 7

2. combine like term's -3+12-10y+35

3.Get the Y value by itself -44 from both sides -44-2y=

                                                                             -44         -44

4. divide negative 2 from both sides 2y=-44

                                                            -2= -2

Answer:

ar some point pattern A will have the same numbers as pattern B as it moves along like if you add 3 for 2 more times in pattern A it will have 24 and so on..

Answer:

[tex]\Large \boxed{\mathrm{see \ below}}[/tex]

Step-by-step explanation:

Given.

(4x)/7 - 6 = -20

The x variable should be isolated on one side of the equation.

Adding 6 to both sides of the equation.

(4x)/7 - 6 + 6 = - 20 + 6

(4x)/7 = - 14

Multiplying both sides of the equation by 7.

(4x)/7 × (7) = - 14 × (7)

4x = - 98

Dividing both sides of the equation by 4.

(4x)/4 = - 98/4

x = - 24.5

Answer:

[tex]\boxed{x = -1}[/tex]

Step-by-step explanation:

Hey there!

Well a vertical line means it starts with x =,

Whereas a horizontal line starts as y =.

So if the x intercept is at -1 then the equation is x= -1.

Hope this helps :)

Answer:

x = -1

Step-by-step explanation:

Let f(x) = mx+b. Also, let g(x) be the inverse of f(x)

To find the inverse, we start with y = mx+b and swap x and y. From there, we solve for y like so

y = mx+b

x = my + b

x-b = my

my = x-b

y = (x-b)/m ... note m is in the denominator, so m cannot be 0

y = (x/m) - (b/m)

y = (1/m)x - (b/m)

g(x) = (1/m)x - (b/m)

This new equation is linear because it is in the form (slope)x+(y intercept)

The new slope is 1/m and the new y intercept is -b/m

So this proves that the inverse g(x) is linear when f(x) is linear.

The inverse function is:

[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]

Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].

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

[tex]y = mx + b[/tex]

In which:

[tex]x = my + b[/tex]

[tex]my = x - b[/tex]

[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]

Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].

Answer:

The statement that is true is:

A debt of $17 is a larger value than a debt of $20.

Step-by-step explanation:

Let us look at the statements one after the other to determine if they are true or not:

1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$

2) One half an apple is equivalent to 8 fourths apples:

one half an apple = [tex]\frac{1}{2}\ of\ an\ apple[/tex]

8 fourths of an apple = [tex]\frac{8}{4} = \frac{2}{1}\ of\ and\ apple[/tex]. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.

3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:

8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009

4) [tex]\frac{2}{3}\ below\ zero[/tex] is a lower temperature than 6 below zero:

[tex]\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ[/tex]

6 below zero = - 6°

On the number line, -6 is smaller than [tex]-\frac{2}{3}[/tex] hence the statement is false.

Answer:

the inverse is the third choice

Answer:

1258

Step-by-step explanation:

SI = (P x R x T) / 100

SI = Simple Interest

P = Principal

R = Rate

T = Time

SI = (850 x 8 x 6)/100

=> SI = 85 x 8 x 6 /10

=> SI = 680 x 6 /10

=> SI = 68 x 6

=> SI = 408

The total amount after 6 years = Principal + Simple Interest

=> Total Amount = 850 + 408

=> Total Amount = 1258

After 6 years, the amount in account is 1258.

Answer:

c = b/a

Hint: | Transform b/c = a so that c only appears in the numerator.

Take the reciprocal of both sides:

c/b = 1/a

Hint: | Solve for c.

Multiply both sides by b:

Answer:

x=3 y=1

x=4 y=2

x=5 y=3

x=6 y=4

Step-by-step explanation:

add y to both sides to get:

2x-4=y

pull out the 2 from 2x-4 to get:

2(x-2)-y = 0

We need to know that x-2 cannot equal 0 or else the solution will be negative. So we need to make x-2 equal to any other number that is not negative and make y the inverse of x-2 so they cancel out and be zero. so some solutions are:

x=3 y=1

x=4 y=2

x=5 y=3

x=6 y=4

Answer:

[tex]\bold{g(x) = x+1}[/tex]

Step-by-step explanation:

Given a function:

[tex]F(x) =-x+1[/tex]

To find:

Function [tex]g[/tex] whose graph is a reflection in the y -axis for the given function = ?

Solution:

First of all, let us learn about the reflection of a point ([tex]x, y[/tex]) in y axis.

For example, let us consider a point (3, 2) on the coordinate axis.

The reflection of this point in y axis will be (-3, 2)

OR

In other words, To find the image of a point in y axis:

the x coordinate is made of negative sign and y coordinate remains the same.

A line is nothing but a number of points joined together.

So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.

Given that [tex]F(x) =-x+1[/tex]

We can write it as:

[tex]F(x)=y =-x+1[/tex]

To find its reflection:

[tex]g(x) = - (-x)+1\\\Rightarrow \bold{g(x) = x+1}[/tex]

Please refer to the attached graphs of [tex]F(x)[/tex] and [tex]g(x)[/tex] .

So, the answer is:

[tex]\bold{g(x) = x+1}[/tex]

Answer:

Answer: y = 40

Explanation: In this problem, notice that y is being divided by 8 so to

get y by itself, we need to multiply both sides of the equation by 4.

So we have (8)(y/8) = (5)(8).

Noice that on the left side, the 8 and 8

cancel each other out so we're just left with y.

On the right side, we have (5)(8) which is 40.

So we have y = 40.

Answer: so what you want to do is you have the equation.

Y/8=5

so you can just say it's Y divided by 8 = 5.

The inverse operation of division is multiplication.

so know it would be y×8=5. so you would multiply 8 by 5. which would be 40 so y=40. a way to check it is subsituting 40 for Y. 40/8=5

Answer:

-5 = p

Step-by-step explanation:

-7 - p= p +3

Add p to each side

-7 - p+p= p+p +3

-7 = 2p+3

Subtract 3 from each side

-7-3 = 2p+3-3

-10 = 2p

Divide each side by 2

-10/2 = 2p/2

-5 = p
