An object at a temperature of 35 °F was put in an industrial freezer. The temperature of the object changed by y °F. The tempera

ture of the object is now less than -5 °F. Which statement describes whether an equation or an inequality better models the situation? A. An equation models the situation better, because there could be multiple values for y. B. An equation models the situation better, because there is a single value for y. C. An inequality models the situation better, because y could be a range of values extending into the positive direction on the number line. D. An inequality models the situation better, because y could be a range of values extending into the negative direction on the number line.

HELP PLEASE ASAP IM SO CONFUSED!!!!!!!!
liubo4ka [24]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the points (-4, -6) and (2, 6). Substitute:

m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b

Put the coordinates of the point (2, 6) to the equation of a line:

6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2

<h3>Answer: y = 2x + 2</h3>

What is the value of y in the equation 4(5y − 8 − 2) = 185 − 15? 8. 5 9. 7 10. 5 42. 5.
Bezzdna [24]

Answer:

10.5 is the answer

Step-by-step explanation:

4(5y−8−2)=185−15

(4)(5y)+(4)(−8)+(4)(−2)=185+−15(Distribute)

20y+−32+−8=185+−15

(20y)+(−32+−8)=(185+−15)(Combine Like Terms)

20y+−40=170

20y−40=170

20y−40+40=170+40

20y=210

20y/20=210/20

y=21/2

y=10.5
