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

Simplify the following expression:<br><br> 2(x+7) - (x+2)

Mekhanik [1.2K]

Answer:

x + 12

Step-by-step explanation:

$(2)(x)+(2)(7) + (-1)(x) + (-1)(2)$
$2x + 14 -x -2$
$(2x-x)+(14-2)$
$x + 12$

Therefore, the answer is x + 12.

Help me please with this math. find x and y

erastova [34]

Answer:X= 1.84. Y= 3.08

Step-by-step explanation:

-9x+8y =8 ............i

-8x+10y= -16........ii

Multiply equation I by 8

Multiply equation ii by 9

-72x+64y = 64 ..... iii

-72x+90y = 144 ..... iv

Subtract iv from iii

-26y = -80

y= 80/26

y= 3.08

Put the value of y in equation i

-9x+8y =8

-9x+8(3.08) = 8

-9x+24.64 = 8

-9x = 8-24.64

-9x=-16.64

Divide both side by 9

-9x/-9 = -16.64/-9

X= 1.84
