At 7:00 a.m., the temperature was 8°C. What was the temperature at midnight if the temperature was 10° lower? Incorrect answer
astra-53 [7]

Answer:

b)−2° C

Step-by-step explanation:

hello! To solve this problem you should remember how are the operations with negative numbers, for this the only thing we must do is make a subtraction between the initial temperature (8° C) and the negative change of temperature (10° C)

Ti= initial temperature =8° C

ΔT= temperature change  =10° C

new temperature=Ti-ΔT

new temperature=8° C-10° C=-2° C

in conclusion the answer is -2° C

Find an equation (in term of x) of line through the points (-1,3) and (1,4)
Serjik [45]
ANSWER

The equation is
2y - x = 7


EXPLANATION

The equation of the line that passes through the point (-1,3) and (1,4) can be found using the formula,

y-y_1=m(x-x_1)

where

m =  \frac{4 - 3}{1  -  - 1}

m =  \frac{1}{2}
is the slope and

(x_1,y_1)
is a point on the line.



The equation of the line becomes,


y - 4 =  \frac{1}{2} (x - 1)


Multiply through by 2 to get,.

2y - 8 = x - 1

Or

2y - x = 7

A=(s-2)180 solve for s
Snowcat [4.5K]

You said that                         A              = (s-2) 180

Divide each side by  180 :    A/180       = s-2

Add  2  to each side:            A/180 + 2 = s
