Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?

Nastasia [14]

Answer:

d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Step-by-step explanation:

The distance formula is d= $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }$ .

6 is $x_{2}$ , 9 is $x_{1}$ , 3 is y $_{2}$ , and -2 is y $_{1}$ .

When you plug these into the formula, you get d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

the slope of line b is -2. this is because parallel lines share the same slopes, but different y-intercepts.

PLEASE HELP!!! The formula F =9/5 C + 32 expresses Fahrenheit temperature in terms of Celsius temperature. Find the Celsius temp

mrs_skeptik [129]

Answer:

The Celsius temperature is 5° when the Fahrenheit temperature is 41°.

Step-by-step explanation:

Given that:

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

Where,

F represents the temperature in Fahrenheit

C represents the temperature in Celsius

For calculating Celsius temperature from 41° Fahrenheit, we will put F=41 in given equation

$41=\frac{9}{5}C+32$

Subtracting 32 from both sides

$41-32=\frac{9}{5}C+32-32\\9=\frac{9}{5}C$

Multiplying both sides by 5/9

$\frac{5}{9}*9=\frac{5}{9}*\frac{9}{5}C\\5=C\\$

C = 5°

Hence,

The Celsius temperature is 5° when the Fahrenheit temperature is 41°.

Are these ratios equivalent 3/7, 18/42

galina1969 [7]

Yes, the two ratios are equivalent. If you multiply both the numerator and the denominator by 6, you will get 18/42.
