Step-by-step explanation:

Step-by-step explanation:

a. Substituting (0,b) into the point-slope form, we get y = mx + b. Plug in 0 to the x1 value and plug in b into the y1 value. Add b to both sides and you should get y = mx+b.

b. Slope-intercept shows how to get specific x or y values at a point if three of the four variables (y, m, x, or b) are known. Point slope form is used mainly when finding the slope from two distinct points. (Later, you'll learn it's importance in the definition of a derivative :).)

c. y = mx + b. Refer to a.

Answer:

a) y-b=m(x-0)

b) (x1, y1) , point-slope, y, slope-intercept

5 shaded sections are 20% of 25 equal size sections.

Given that, you divide a bar diagram into 25 equal-size sections and shade 5 sections.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Now, 5/25 × 100

= 0.2 × 100

= 20%

Therefore, 5 shaded sections are 20% of 25 equal size sections.

Answer:

222 meters

Step-by-step explanation:

Zayn puts a total of 888 meters of garland around a square window.

Because a square has all equal sides, divide the amount of garland he used by 4 to find how much is used per side:

888 ÷ 4 = 222

So, the height of the window is 222 meters.

Identify what you are asked to find. What is the sales tax?

Choose a variable to represent it. Let t = sales tax.

Write a sentence that gives the information to find it. The sales tax is 6.5% of the purchase price.

Translate into an equation. (Remember to change the percent to a decimal).

Simplify. t = 25.48

Check: Is this answer reasonable? Yes, because the sales tax amount is less than 10% of the purchase price.

Write a complete sentence that answers the question. The sales tax is $25.48.

Identify what you are asked to find. What is the total cost of the bicycle?

Choose a variable to represent it. Let c = total cost of bicycle.

Write a sentence that gives the information to find it. The total cost is the purchase price plus the sales tax.

Translate into an equation. (Remember to change the percent to a decimal).

Simplify. c = 417.48

Check: Is this answer reasonable? Yes, because the total cost is a little more than the purchase price.

Write a complete sentence that answers the question. The total cost of the bicycle is $417.48.

You can use the method of calculating the percentage of an amount to find out the discount amount.

The discount price for the given condition was $205.2

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]

First we will find the marked price since the discount price was calculated on the marked price.

Since marked price was 150% of the cost price $456, thus,

[tex]\text{Marked price} = \dfrac{456}{100} \times 150 = \$684[/tex]

Thus, the marked price of the furniture was $684

Now, since the discount offered on the price was 30%, thus,

[tex]Discount = \dfrac{\text{Marked price}}{100} \times \text{Discount percent} =\dfrac{684}{100} \times 30\\\\Discount = \$205.2[/tex]

Thus,

The discount price for the given condition was $205.2

tn=a + [(n-1)d]

204=3+(n-1) 3

204-3= 3n- 3

201=3n-3

201+3=3n

204=3n

n=204/3

n =68

As we know

Sn=n/2(t1+tn)

Sn=68/2(3+204)

Step-by-step explanation:

L = length

W = width

L = W + 9

A = 112 = LW = (W+9)W

So,

W2 + 9W = 112

W2 + 9W - 112 = 0

Factoring

(W-7)(W+16) = 0

W = 7, -16

We discard W = -16, since a measurement cannot be negative.

W = 7

And since L = W + 9, then L = 7 + 9 = 16
