Answer:

Step-by-step explanation:

The line on the left has equation y = x + 1

The end of the line has an open circle at x = 2 meaning that x ≠ 2

Thus it is defined as y = x + 1 for x < 2

The line on the right has equation y = x + 2

The start of the line has a closed circle at x = 2 meaning that x can equal 2

Thus it is defined as y = x + 2 for x ≥ 2

Thus the definition for the function is B

A thermometer gives a reading of 26 degrees Celsius. Use the formula c =5/9(f-32). Write the inverse function and use it to find

guajiro [1.7K]

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

$C = \frac{5}{9} (F - 32)$

Multiply both sides by 9

$9C = \frac{5(9)}{9} (F - 32)$

Simplify

$9C = 5(F - 32)$

Divide both sides by 5

$\frac{9}{5} C = \frac{5}{5} (F - 32)$

Simplify

$\frac{9}{5} C = F -32$

Add 32 in both sides

$\frac{9}{5} C + 32 = F - 32 + 32$

Simplify (Inverse)

$\frac{9}{5} C + 32 = F$

Substitute to find F

$\frac{9}{5} (26) + 32 = F$

Simplify

F = 46.8 + 32

Result

F = 78.8

Ellie's Bakery is having a grand opening sale. All pastries are being discounted by 25%. Let x represent the regular price of an

Sindrei [870]

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70

Step-by-step explanation:

Step 1 :

Let x be the regular price of the pastry in the bakery

Percentage of discount = 25%

Amount of discount = 0.25 x

The expression to find the sale price of pastry = x - 0.25 x = 0.75 x

Step 2 :

Sale price of the pastry bought by Kimberly = $2.03 = 0.75 x

<u>To find the regular price</u>

0.75x = 2.03

x = $\frac{2.03}{0.75}$ = 2.70

Regular price of the pastry bought by Kimberly = $2.70

Step 3 :

Answer :

a) The expression to find the sale price of pastry = 0.75 x

b) The regular price of the pastry bought by Kimberly = $2.70
