Is 5 in the solution of x+3>8?

Mathematics

8 0

Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.

In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.

Your steps could look like this

x+3 > 8

5+3 > 8 ... replace x with 5

8 > 8 ... this is a false inequality

Answer: D

Step-by-step explanation:

No such thing as a vertex of a graph... Eliminate B and C. Try f(3) = 4(3-5)(3+3) is not zero eliminate A. So answer must be D. Check: f(-3) has factor -3+3 = 0. f(5) has factor 5-5 = 0.

Answer: $\sqrt{37}$

=====================================

Work Shown:

6x-y = -3 is the same as 6x-y+3 = 0

6x-y+3 = 0 is the form Ax+By+C = 0 with A = 6, B = -1, C = 3.

The distance d that line is from the point (p,q) = (6, 2) is found by the following

$d = \frac{A*p+B*q+C}{\sqrt{A^2+B^2}}\\\\d = \frac{6*6-1*2+3}{\sqrt{6^2+(-1)^2}}\\\\d = \frac{36-2+3}{\sqrt{36+1}}\\\\d = \frac{37}{\sqrt{37}}\\\\d = \frac{37\sqrt{37}}{37}\\\\d = \sqrt{37}\\\\d \approx 6.08276\\\\$

Pavel [41]

Question

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?

a) Negative 5 c d

b) c d minus 8 d

c) 5 c d minus 8 d

d) Negative 5 c d minus 8 d

Answer:

a) Negative 5cd or -5cd

Step-by-step explanation:

The question asks:

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?

This is expressed mathematically as:

-3cd - d(2c - 4) - 4d

= -3cd -2cd + 4d - 4d

= -5cd + 0

= -5cd

The answer is negative 5cd(in words) or - 5cd
