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: 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

====================================================

Explanation:

The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.

----------

For the variable portions, we can

Each time we see z^3 show up, so this is the largest common factor among the three variable terms.

----------

The two results we got were 2 and z^3

Putting the two results together, we end up with the overall GCF of 2z^3

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:

Answer:

Method 1 (using the area of a whole circle and dividing by 4)

First work out the area of the whole circle by substituting the radius of 8cm into the formula for the area of the circle:

A = π ×r²

= π ×8²

= 64π (leave the answer as an exact solution as this need to be divided by 4).

So all you need to do now is divide the answer by 4:

Area of a quadrant = 64π ÷4 = 16π = 50.3 cm² to 3 significant figures.

Method 2 (using ¼ πr²)

Substitute r = 8 directly into the formula A = ¼ πr².

A = ¼ πr².

A = ¼ × π × 8².

A = 50.3 cm²

As you can see it gives exactly the same answer as method 1.

Answer:

64pi / 4 = 16pi, or 50.27

Step-by-step explanation:

We use the area formula:

π * r^2 = Area

Substitute in 8 for r to get 64pi

Then all you have to do is divide 64pi by 4 to find a quarter of the area of the circle, which is 16pi. Or if you want rounded to nearest tenth, 50.27

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:

Amount per kilogram, undercharged or overcharged is 0.50

Step-by-step explanation:

Given:

cost of T-bone steaks per pound = $ 15.99

weight listed on package = 5.77 lb

Accuracy of the scale = 1/32 lb

To find:

Amount undercharged or overcharged

Solution:

Let x represent the weight of the package.

Then compute the error in the weight

| x - 5.77 | < 1 / 32

This makes an absolute value inequality

If an inequality is given in the form | x | < a then solution is in the form:

–a < x < a.

If an inequality is in the form | x | > a, then solution splits in the form:

x < –a or x > a.

compute the amount undercharged or overcharged:

First multiply the above inequality by cost of T-bone steaks per pound

15.99 |x - 5.77| < 15.99 (1 / 32)

15.99 |x - 5.77| < 15.99(0.03125)

15.99 |x - 5.77| < 0.4996875

15.99 |x - 5.77| < 0.50

Hence the amount undercharged or overcharged is $0.50

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

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:

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:

[tex] X = 70.5 [/tex]

Step-by-step explanation:

The law of Cosine given can be written in another form to make the Cos(C) the subject of the formula. Which is: [tex] cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex]

Where,

a = 20 ft

b = 18 ft

c = 22 ft

C = X

[tex] cos(X) = \frac{20^2 + 18^2 - 22^2}{2*20*18} [/tex]

[tex] cos(X) = \frac{400 + 324 - 484}{720} [/tex]

[tex] cos(X) = \frac{240}{720} [/tex]

[tex] cos(X) = 0.3333 [/tex]

[tex] X = cos{-1}(0.3333) [/tex]
