which of the following is equivalent to 7x+5<-2(4x-3)
x>11
-x<1
15x<-11
15x<1

Answers

Answer:

7x+5< -8x+6

=15x<1

The equivalent inequality is 15x<1. Therefore, option D is the correct answer.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is 7x+5<-2(4x-3).

Now, 7x+5<-8x+6

Subtract 5 on both the sides of an inequality, we get

7x<-8x+1

Add 8x on both the sides of an inequality, we get

7x+8x<1

15x<1

Therefore, option D is the correct answer.

find the length of BE BC=3x+47 DE=10 BD=x+27 CE=x+26

Answers

Answer:

B____C____D_____E

BC+ CE = BD + DE

(3x+47) + (x+26) = ( x+27) + (10)

4x + 73 = x + 37

4x – x = 37 – 73

3x = ‐ 36

x = – 36/ 3 —> x = 12

BC = 3x + 47 = 3(-12) + 47 = - 36 + 47 = 11

BD = x+ 27 = –12+27 = 15

CE = x + 26 = –12+26= 14

So;

BE = BD+ DE = 15+ 10= 25

Or ;

BE= BC + CE = 11+ 14 = 25

Answers

Answer:

{(4, -7), (-2, -1), (-7,4), (9, -1)}

Step-by-step explanation:

Every other set of ordered pairs has an x-value that has more than one y-value. This is against the rules of a function. Therefore, {(4, -7), (-2, -1), (-7,4), (9, -1)} represents a function.

Write an equivalent expression in standard form for
(5x + 4)(7x+ -12x + 27).


Answers

Answer: -25x² + 115x + 108

Concept:

When encountering questions that ask for simplifying polynomial expressions, using the method FOIL would be easier:

First, which means multiplying the first terms together;Outer, which means that we multiply the outermost terms when the binomials are placed side by side;Inner, which means multiply the innermost terms together;Last, which means multiplying the last term in each binomial together;

Solve:

Given

(5x + 4) (7x + (-12x) + 27)

Combine like terms in the parentheses

=(5x + 4) (7x - 12x + 27)

=(5x + 4) (-5x + 27)

Expand parentheses and apply the FOIL method

=-25x² + 135x - 20x + 108

Combine like terms

= [tex]\boxed {-25x^2+115x+108}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer:

[tex]\boxed {\boxed {\sf -25x^2+115x+108}}[/tex]

Step-by-step explanation:

We are asked to find an equivalent expression for (5x + 4)(7x+ -12x + 27). Note that we are multiplying 2 polynomials.

[tex](5x + 4)(7x+ -12x + 27)[/tex]

Notice that the second polynomial has like terms. There are 2 terms with an x (7x and -12x) and we can combine them.

[tex](5x + 4)[(7x+ -12x) + 27][/tex]

[tex](5x + 4)[(-5x) + 27][/tex]

[tex](5x+4)(-5x+27)[/tex]

Now we are multiplying 2 binomials. Therefore, we use the FOIL method. We multiply the First terms, the Outside terms, the Inside terms, and the Last terms.

First:  5x * -5x = -25x²Outside: 5x * 27 = 135x Inside: 4* -5x = -20x Last: 4 * 27=108

[tex]-25x^2+135x-20x+108[/tex]

Notice there are 2 terms with an x ( 135x and -20x). They are like terms and can be combined.

[tex]-25x^2+(135x-20x)+108[/tex]

[tex]-25x^2+115x+108[/tex]

The equivalent expression in standard form is -25x²+115x+108

There are □terms in the sequence 1, 3, 9, 27, 81, 243, .... 6561

Answers

Answer:

There are(2) terms in sequence1,3,9,27,81,243...6561

Step-by-step explanation:

1,3,9,27,81,243,729,2187,6561

There are 8 terms in the sequence 1, 3, 9, 27, 81, 243, .... 6561.

To determine the number of terms in the given sequence, we can observe that each term is obtained by multiplying the previous term by 3. Starting with the first term, which is 1, we can continue this pattern to find subsequent terms.

1 * 3 = 3

3 * 3 = 9

9 * 3 = 27

27 * 3 = 81

81 * 3 = 243

243 * 3 = 729

729 * 3 = 2187

2187 * 3 = 6561

As we can see, the sequence follows a pattern of multiplying each term by 3. In total, we have gone through 8 terms to reach 6561.

Find the area of the shaded region with the following measurements:

Answers

Answer:

132

Step-by-step explanation:

First you need to find the area of both regions (shaded and not shaded)

To find the shaded regions area multiply length by width

20 x 8 = 160

Then find the area of the unshaded region

7 x 4 = 28

Finally subtract the unshaded region from the shaded region

160 - 28 = 132
