Answer:

1

Step-by-step explanation:

Multiplicative inverse is the opposite of the number. For example, the multiplicative inverse of 7 is 1/7.

To get the multiplicative inverse we first have to turn -2  2/5 into an improper fraction.

Which is -12/5 now flip it to get the (MI) which is -5/12

Which equals 1

YOU'RE RIGHT!!

N order to write an expression like (5x + 4)3 in expanded form, it helps to look at (5x + 4) as just one number, n.
Vladimir79 [104]

The expression (5x + 4)^3 in expanded form is 125 x3 + 300 x2 + 240 x + 64.  The expression will have also a root of x = -4/5. This is the form of trinomial expansion and can be  solve by multiplying the the term 3 times.

STATISTICS in a recent year the mean score on the mathematics section of the SAT test was 515 and the standard deviation was 114
vesna_86 [32]

An absolute value inequality to find the range of SAT mathematics test scores within one standard deviation of the mean is; |x – 515| ≤ 114

<h3>How to Write Inequalities?</h3>

A) We are told that;

Mean score = 515

Standard deviation = 114

We are now given that people within one deviation of the mean have SAT math scores that are no more than 114 points higher or 114 points lower than the mean. Thus, the absolute value inequality is;

|x – 515| ≤ 114

B) The range of scores to within ±2 standard deviations of the mean is;

Range = 515 ± 2(114)

Range = 287 to 743

&gt; Next question You can retry this question below What is the slope of a line that is parallel to the line – 7x - y = 2 ? Wri
irakobra [83]

Answer:

The slope of parallel line m = -7 is an integer

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the parallel line

                     -7x-y = 2

we know that the slope of the two parallel lines are equal

m₁ = m₂

The given parallel line equation

                           - 7 x - y = 2

The slope-intercept form

                             y = - 7x -2

comparing

                             y = mx +C

slope of parallel line m = -7 is an integer

y- Intercept  c = -2
