-13F is less than -12F and -9F is greater than -12F
VLD [36.1K]3 years ago
6 0

Answer:

-13F is less than<em> </em>-12F, and -9F is greater than -12F


Step-by-step explanation:

You can prove this because in the problem is states that -13F < -12F < -9F

If you utilize this, you find that the first statement is quite obvious:

-13F is less than -12F

The second statement is a little trickier. Since in the original inequality is states that -12F < -9F, but you want to know the relationship between the switch, you would just flip the sign in the middle, getting you:

-9F is greater than -12F

You could also prove this simply with the rules of negative values (which work inversely from positives).

WILL GIVE BRAINLIEST
Triss [41]

Answer:

(-10, 0) and (0,-5)

Step-by-step explanation:

For the function f(x)=-\dfrac{1}{2}x-5, find x-intercept and y-intercept:

1. when y=0, then

0=-\dfrac{1}{2}x-5,\\ \\\dfrac{1}{2}x=-5,\\ \\x=-10;

2. when x=0, then

y=-\dfrac{1}{2}\cdot 0-5,\\ \\y=-5.

You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function f(x)=-\dfrac{1}{2}x-5.

hich of the following expressions is equivalent to |x + 4| &lt; 5? A. –5 &gt; x + 4 &lt; 5 B. –5 &lt; x + 4 &lt; 5 C. x + 4 &lt;
Airida [17]

Answer:

option B

Given : |x + 4| < 5

A. –5 > x + 4 < 5

B. –5 < x + 4 < 5

C. x + 4 < 5 and x + 4 < –5

D. x + 4 < 5 or x + 4 < –5

In general , |x|< n where n is positive

Then we translate to -n < x < n

|x + 4| < 5

5 is positive, so we translate the given absolute inequality to

-5 < x+4 < 5

So option B is correct

Alpha false and true Which of the following statements are true? If false, explain briefly.
solmaris [256]

Answer:

A. False

B. True

C. True

D.True

Step-by-step explanation:

A. False . The significance level or alpha is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. 0.01 alpha is better than 0.05 alpha . 0.01 indicate a 1% risk of rejecting the null hypothesis when it is true .

B. True . If the p-value is less than alpha, we reject the null hypothesis . Therefore statistically significant.

C . True . If the p-value is less than alpha, we reject the null hypothesis

D. True . Alpha will be greater than p-value . Therefore we will reject .
