Evaluate the expression: –(31 + 2) + 72 – (–5)2.

Mathematics
1 answer:

4 0

Answer:

 14

Step-by-step explanation:

Order of operations rules require that we do any work inside parentheses first.  Thus,

–(31 + 2) + 72 – (–5)^2

becomes:

     -33    + 72 -  25, or

               14

Important:  Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.

5. Which of the following is the equation of a line. that passes through the points (0.8) and (6.4)7 Use of
andriy [413]

See in the explanation

<h2>Explanation:</h2>

In this exercise, <em>we have the following points:</em>

(0.8) \\ \\ (6.4)

And <em>the following linear equations:</em>

(1) \ y=-x+8 \\ \\ (2) \ y=\frac{3}{2}x+6 \\ \\ (3) \ y=-\frac{4}{5}x+4 \\ \\ (4) \ y=\frac{1}{2}x+8

When plotting these graphs, we find the following facts:

<h3>For (1):</h3>

We see the graph in the first figure below. The graph only passes through the point (0, 8)

<h3>For (2):</h3>

This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)

<h3>For (3):</h3>

This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)

<h3>For (4):</h3>

This is the fourth graph below. The graph only passes through the point (0, 8)

So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>

A positive integer is 11 more than 18 times another. Their product is 6030. Find the two integers.
allsm [11]

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335
