Answer:

The equation represents the inequality will be y < −2x + 3.Option d is correct.

Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.

Different types of linear inequalities can be represented in a variety of ways.

The linear equation with slope m and intercept y is given as;

y=mx+c

The inequalities are as follows;

(a).  y > 2x +3

(b).  y < 2x+ 3

(c).  y > −2x+ 3

(d). y < −2x+ 3

Because the line meets the y-axis,(0,3)the y-intercept is 3.

The points are (0,3)and(1,1)

The line's slope may be calculated as follows.

[tex]\rm m= \frac{1-3}{1-0} \\\\ \rm m= -2[/tex]

On putting the given origin value;

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

From all the data obtained we get the equation given in option d is correct.

Hence the equation that represents the inequality will be y < −2x + 3.Option d is correct.

Answer:

c

Step-by-step explanation:

To find the maximum point, differentiate:

D' = -8p +160

Set to zero and solve for p:

D' = 0

⇒ -8p +160 = 0

⇒ 8p = 160

⇒ p = 20

Input p = 20 into the original equation to find D:

D = -4(20)² + 160(20) -310 = 1290

Therefore, the price is $20 and the maximum number of drills is 1,290

[tex]\boxed{x = -17}[/tex]

✽ Simplify both sides of the equation.

[tex]\frac{x+2}{5}-\frac{x+1}{4}=1[/tex]

[tex]\frac{1}{5}x + \frac{2}{5} + \frac{-1}{4} = 1[/tex] (Distribute)

[tex](\frac{1}{5}x + \frac{-1}{4} ) + (\frac{2}{5} + \frac{-1}{4}) = 1[/tex] (Combine Like Terms)

[tex]\frac{-1}{20}x + \frac{3}{20} = 1[/tex]

✽ Subtract 3/20 from both sides.

[tex]\frac{-1}{20}x + \frac{3}{30} - \frac{3}{20} = 1 - \frac{3}{20}[/tex]

[tex]\frac{-1}{20}x = \frac{17}{20}[/tex]

✽ Multiply both sides by 20/(-1).

[tex]( \frac{20}{-1}) * (\frac{-1}{20}x) = (\frac{20}{-1}) * (\frac{17}{20})[/tex]

Hence, x = -17

Answer:

y= 16, 64, 256, 1024

y/x= 16/2, 64/3, 256/4, 1024/5,

Step-by-step explanation:

    This is just like any other equation, except instead of x being a number, it is an exponent. For example, when x equals 2, y equals 16 because y always equals four to the power of x.  This applies to all of the parts in your table. when x equals 3, y equals 4^3 (4 times 4 times 4) which is 64, and when x equals 4, y equals 4^4 (4 times 4 times 4 times 4), which is 256.

    For the y over x part that is just the value y, divided by the value x. For the first line on the table x equals 2, and we know y equals 16 (4^2 is 4 times 4, which is 16) so 16 divided by 2 is 8. That is the answer.

Hope this helps :)

Answer:

x+y≤15

6x+9y≥95

Step-by-step explanation:

Let x be the hours worked for babysitting and let y be the hours worked for house cleaning.

As Suzie babysits for $6 per hour. She also works as a house cleaner for $9 per hour.

Total hours she can work= 15 hours per week.

Hence,

x + y is less than or equals to 15

But since she wants to make at least $95 per week. It implies that,

6x + 9y is greater than or equal to 95

So from the statements above, the equations will be:

x+y≤15

6x+9y≥95

Answer:

24

Step-by-step explanation:

*Combine multiplied terms into a single fraction

1/4h=6 → 1h/4=6

*Multiply by 1

1h/4=6 → h/4=6

*Multiply all terms by the same value to eliminate fraction denominators

h/4=6

4×h/4=4×6

*Multiply the numbers

h=4×6

Step-by-step explanation:

Percentages represent a proportion of a number. This means that a percentage represents part of a whole.

In this question, Captain Perguin ate 10% of 150 crackers. There are 2 ways to solve this problem explained below.

Multiplication

One way to find a percentage is through multiplication.

Shortcut

Multiplication is not the only way to find the answer. This question is special because it asks for 10%. Instead of multiplication, you could simply move the decimal point of the original number 1 digit to the left. This means that 10% of 150 must be 15. Remember this trick does not work for percentages other than 10%.

Solution: 89/8 or 11.125

HOPE THIS HELPS!!! :)

Step-by-step explanation:

remember the priorities :

first brackets

then exponents

then multiplications and divisions (from left to right)

then additions and subtractions (from left to right)

remember, a fraction is a division ...

10 + (2 × 3)² ÷ 4 × 1/2³ =

= 10 + 6² ÷ 4 × 1/2³ =

= 10 + 36 ÷ 4 × 1/8 =

= 10 + 9 × 1/8 =

= 10 + 9/8 =

= 10 9/8 = 11 1/8 = 89/8 = 11.125

Using limits, it is found that the correct statement is:

they give what y-values the function is AROUND the given x.

The limit of a function f(x) as a value of x = a is approached is given by:

[tex]y = \lim_{x \rightarrow a} f(x)[/tex]

The limit can be calculated at a point in which a function is not continuous, for example, in which we consider the lateral limits, which is not the exact value at x = a, but the value of the function as x approaches a by the left and by the right, hence the correct statement is:

they give what y-values the function is AROUND the given x.

Step-by-step explanation:

To simplify, we multiply the like terms, which are the constant, and the s. For the constants of 1.5, and 3.5, we just do 1.5x3.5 to get 5.25, and when we multiply both s's together, we get [tex]s^2[/tex]. adding those 2 together, we get 5.25[tex]s^2[/tex]. so it would be the third one down.

Answer:

x = 26

y = 34

Step-by-step explanation:

Let the boxes stocked by Terri = x

Therefore the boxes stocked by Kay = x + 8 because he stocked 8 more boxes

Hence since they both stocked 60 boxes

x+x+8 = 60

2x = 60 - 8

2x = 52

divide both sides by 2

x = 26

Terri stocked 26 boxes and Kay stocked 26+8 boxes = 34 boxes
