Answer:

140

Step-by-step explanation:

P: parenthesis

E: exponents

M: multiply

D: Division

A: add

S: subtract

150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is

inside the parenthesis

150-(16+4)/2 you still have parenthesis so solve that next

150-20/2 next you divide because there is no multiplication

150-10 then subtract because there is no addition

140 is your final answer

What is the equation of a line that passes through (0.8) and (3,6)?

nirvana33 [79]

Answer:

$y=\frac{-2}{3}x+8$

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Determine the slope (m)</u>

$m=\frac{y_2-y_1}{x_2-x_1}$ where the given points $(x_1,y_1)$ are $(x_2,y_2)$

Plug in the given points (0,8) and (3,6)

$m=\frac{6-8}{3-0}\\m=\frac{-2}{3}$

Therefore the slope of the line is $\frac{-2}{3}$ . Plug this into $y=mx+b$ :

$y=\frac{-2}{3}x+b$

<u>2) Determine the y-intercept (b)</u>

$y=\frac{-2}{3}x+b$

The y-intercept occurs when x=0. One of the given points is (0,8), so therefore, the y-intercept is 8. Plug this into $y=\frac{-2}{3}x+b$ :

$y=\frac{-2}{3}x+8$

I hope this helps!

Riya looks at the temperature in the kitchen. What is the temperature in the kitchen to the nearest division

insens350 [35]

Answer:

24 degree Celsius

Step-by-step explanation:

Temperature may be defined as the intensity or the degree of heat that is present in any substance or present in the environment. It is the measure of hotness or coldness of any item or surroundings. Temperature is measured with the help of a comparative scale which shows the how hot or cold the place is or item is.

In the context, Riya uses a comparative scale like the thermometer to measure the temperature of the kitchen. The mercury level on the scale rises and stops at a point indicating the temperature of the kitchen.

Thus the temperature of the kitchen according to the scale is $24 ^ \circ C$ .
