Answer:

2 and -4

Step-by-step explanation:

-5|x + 1| + 3 = -12

-5|x + 1| = -15

|x + 1| = 3

x + 1 = 3    /      x + 1 = -3

x₁ = 2        /      x₂ = -4

Answer: Option C.

Step-by-step explanation:

The given inequality is

[tex]x^3+x^2-6x\geq 0[/tex]

Taking x common, we get

[tex]x(x^2+x-6)\geq 0[/tex]

Splitting the middle term, we get

[tex]x(x^2+3x-2x-6)\geq 0[/tex]

[tex]x(x(x+3)-2(x+3))\geq 0[/tex]

[tex]x(x+3)(x-2)\geq 0[/tex]

Related equation is

[tex]x(x+3)(x-2)=0[/tex]

[tex]x=-3,0,2[/tex]

These three points divide the number line in 4 parts.

Interval       Sign of [tex]x(x+3)(x-2)\geq 0[/tex]      Statement

(-∞,-3)              [tex](-)(-)(-)=(-)[/tex]                           False      

(-3,0)              [tex](-)(+)(-)=(+)[/tex]                            True  

(0,2)              [tex](+)(+)(-)=(-)[/tex]                              False      

(2,∞)              [tex](+)(+)(+)=(+)[/tex]                              True  

So, the solution set is (-3,0) ∪ (2,∞).

Thus, minimum value is –3 and no maximum value.

Therefore, the correct option is C.

Answer:

minimum = –3, no maximum

Answer: 1.    

               2. = 12

        3 on the left        = 8

         3 on the right     = 15

        1 on the right      =  20

         2 on the right     =   21/98

B every integers a real number

C every integers is also an interration number.

Answer:

Its 4

Step-by-step explanation:

Because it is

Answer:

4

Step-by-step explanation:

1) First, distribute the negative sign to the -7. Because of this, the -7 will become a positive 7.

Equation: -3+7

2) Next, whenever there are two different signs, we are supposed to subtract the bigger number (7) with the smaller number (3).

Equation: 7-3=4

3) Finally, assign the greatest number sign. in this case, 7 is the greater number, and the 7 is a positive number; therefore, it will be a positive 4.

Hope this helps!

Step-by-step explanation:

Answer:ratio is 14:54 = 42:B. Beavers = 162

Step-by-step explanation:

The ratio demonstrates how often one number is multiplied by another.

The approximate number of beavers exists 162.

The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.

The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.

The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.

Let the ratio be 14 : 54.

As 42 tagged beavers were released.

simplifying the above equation, we get

14 × 3 : 54 × 3

= 42 : 162

Therefore, the approximate number of beavers exists 162.

Working each column from right to left

3 9 7 3

− 2 9 3 7

7 is greater than 3 so you must regroup:

Take 1 from 7, so 7 becomes 6.

Add 10 to 3, so 3 becomes 13.

Answer:

1036

Step-by-step explanation:

Triangle BEC is an isosceles triangle.

The angles opposite the congruent sides are equal

x = measure of missing angle

180 = 54 + 2x

Subtract 54 from both sides

126 = 2x

Divide both sides by 2

63 = x

angle EBC and angle C = 63 degrees

Angle EBC and angle EBA are supplementary.

This means they add up to 180 degrees

180 = 63 + EBA

Subtract 63 from both sides

117 = EBA

the measure of a triangle = 180

Therefore,

The measure of angle AEB = 180 - (40 + 117) = 23 degrees

Step-by-step explanation:

If one of them only ordered soda which costs $1.74 then you do 43.53 - 1.74 =41.79. Then do 41.79 divided by the other 7 people. 41.79 divided by 7 gets you the answer $5.97

Answer:

7/10ths of the picture has been digested.

Step-by-step explanation:

Let's divide this into tenths.

One fifth out of ten is equal to two, since 10/5 = 2. A half of ten is five, because 10/2 = 5. Adding five and two together gives us 7/10ths, which can not be reduced to a smaller amount.

Answer:

Answer:

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, weight is proportional to the density

Step-by-step explanation:

From the question,

Let w denote the weight of the rock in pounds

s denote the size of the rock in cubic inches and

d denote the density of the rock in pounds per cubic inch.

First, we will write the equation connecting w, s, and d.

We get

[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]

That is,

[tex]d = \frac{w}{s}[/tex]

Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, density is proportional to the weight OR weight is proportional to the density
