Please help me answer this question 17

Answer:

Step-by-step explanation:

Let the number be x.

four times the number:

4x

If the exprression is increased by 1, it will become:

4x+1

If the value is between -7 and 13, the value of x will be within the range [-6, 12]

Equating the resulting expression to each end point.

At end point of -6

4x+1 = -6

4x = -6-1

4x = -7

x = -7/4

At the end point of 12:

4x+1 = 12

4x = 12-1

4x = 11

x = 11/4

Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4

Answer:

6

Step-by-step explanation:

3x+14=7x-10

14+10=7x-3x

24=4x

6=x

The value of x in the expression is 6.

To obtain the value of x, we equate both PQ and QR

PQ = 3x + 14

PQ = 3x + 14 QR = 7x - 10

PQ = QR

(3x + 14) = (7x - 10)

3x + 14 = 7x - 10

Collect like terms

3x - 7x = - 10 - 14

-4x = - 24

Divide both sides by - 4

x = - 24 / -4

x = 6

Hence, the value of x = 6

Given Data:

medical insurance paid = 100%.

rent = $800.

Car payment = $600.

Light bill = $100.

Car insurance = $300.

Taxes = $287.

Solution:

Minimum salary to bear all expenses is

S = Basic expenses + Payroll and taxes

S = $( 800 + 600 + 100 + 300 + 287)

S = $2087.00

His monthly salary is $2087.00 .

This is the required amount needed.

Answer:

36 - 0.12h < 12 - 0.6h

Step-by-step explanation:

Large bucket:

36 gallons and is leaking at a rate of 0.12 gallons per hour.

= 36 - 0.12h

Smaller bucket:

12 gallons and is leaking at a rate of 0.6 gallons per hour

= 12 - 0.6h

The inequality that can be used to find the number of hours, h, at which the larger bucket will have less water than the smaller bucket is

36 - 0.12h < 12 - 0.6h

Answer:

a) The unit rate are:

Batch A = 3 3/4 flour per cup of chocolate chips

Batch B = 4 flour per cup of chocolate chips.

b)Batch A is the cookie with the most chocolate chips.

Step-by-step explanation:

In batch A you use 3/4 of a cup of flour to every 1/5 of a cup of chocolate chips.

The unit rate for flour per cup of chocolate chips for batch A =3/4 cups of flour ÷ 1/5 cup of chocolate chips

= 3/4 ÷ 1/5

= 3/4 × 5/1

= 15/4

= 3 3/4 flour per cup of chocolate chips.

In batch B you use 2/3 of a cup of flour for every 1/6 of a cup of chocolate chips.

The unit rate for flour per cup of chocolate chips for batch B =

2/3 of a cup of flour ÷ 1/6 of a cup of chocolate chips.

= 2/3 ÷ 1/6

= 2/3 × 6/1

= 4 flour per cup of chocolate chips.

b)

Number of chocolate chips used in Batch A = 1/5 cup =>0.2 cup

Number of chocolate chips used in Batch B = 1/6 cup => 0.167 cup

0.2 cup is larger than 0. 167 cups.

Therefore, Batch A is the cookies with the most chocolate chip

Answer:

Original rectangle

Length = 20 inches

Width = 10 inches

Step-by-step explanation:

Let

Original rectangle

Width = x

Length = 2x

When both the width and length are increased by 5 inches, the new rectangle has perimeter of 80 inches

New rectangle

Width = x + 5

Length = 2x + 5

Perimeter = 80 inches

Perimeter of a rectangle = 2(length + Width)

80 = 2{(x+5) + (2x+5)}

80 = 2( x + 5 + 2x + 5)

80 = 2(3x + 10)

80 = 6x + 20

80 - 20 = 6x

60 = 6x

x = 60 / 6

= 10

x = 10 inches

The length and width of the original rectangle

Width = x

= 10 inches

Length = 2x

= 2(10)

= 20 inches

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

x = 2.4545... → (1)

100x = 245.4545... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 243 ( divide both sides by 99 )

x = [tex]\frac{243}{99}[/tex]

Answer:

y-3 = (-1/4)(x-4)

Step-by-step explanation:

Point-slope form is written as y-y1 = m(x-x1)

The y - 3 portion comes from the coordinate plotted, where the y-coordinate is 3, so from the function y-y1, y1 = 3.

The m equals the slope, the rise over run. Choose the two coordinates, subtract the y's from each other and the x's from each other, get the absolute value of them, and then put in the fraction (y/x) to get your slope of m. The 2 coordinates you have are (0,4) and (4,3). You subtract |4-0| and |3-4|, so you get for the x's = 4, and the y's=1.  Now the slope was y/x, so 1/4 is your slope for m.

For the x, use the same coordinate you got for your y to get your x, so the x was 4.

Plug them all into the point-slope function to get your answer, which is y - (3), (-1/4) (x - [4])

Answer:

RT = 12 units

Step-by-step explanation:

From the figure attached,

ΔSRQ is right triangle.

m∠R = 90°

An altitude has been constructed from point T to side SQ.

m∠RTQ = 90°

By applying geometric mean theorem in triangle SRQ,

[tex]\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}[/tex]

[tex]\frac{x}{9}=\frac{16}{x}[/tex]

x² = 16 × 9

x² = 144

x = √144

x = 12

Therefore, length of altitude RT is 12 units.

Answer: A is the answer

Step-by-step explanation:

I just took the test!!

It has one real solution if the discriminant of an equation is zero, option (A) is correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

Here:

Discriminant D:

[tex]\rm D =\sqrt{b^2-4ac}[/tex]

D = 0

[tex]\rm x = \dfrac{-b \pm0}{2a}[/tex]

x = -b/2a (one real solution)

Thus, it has one real solution if the discriminant of an equation is zero, option (A) is correct.

======================================================

Explanation:

This sequence is arithmetic

The first term is a = -9

The common difference is d = 6 since we're adding 6 to each term to get the next one (eg: -3+6 = 3 or 3+6 = 9 or 9+6 = 15)

Plug those values into the arithmetic nth term formula below

an = a + d*(n-1)

an = -9 + 6*(n-1)

an = -9 + 6n-6

an = 6n - 15

--------------

As a check, let's plug in something like n = 1

an = 6n - 15

a1 = 6*1 - 15

a1 = 6 - 15

a1 = -9

We see that the 1st term is -9, which matches the sequence given

Now let's plug in n = 2

an = 6n - 15

a2 = 6*2 - 15

a2 = 12 - 15

a2 = -3

The 2nd term is -3. This also matches.

I'll let you check the other values of n to confirm the answer.

Answer:

10

Step-by-step explanation:

Here we go!

Slope Formula:

[tex] \frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} } [/tex]

What we know: (-4, -52) and (-1, -22)

Plug in the numbers!

[tex] \frac{ - 52 - ( - 22)}{ - 4 - ( - 1)} [/tex]

Fix it!

[tex] \frac{ - 52 + 22}{ - 4 + 1} [/tex]

Add

[tex] \frac{ - 30}{ - 3} [/tex]

Divide

(negative divided by a negative is a positive!!)

Slope is 10

I think the answer is 15/40

Answer:

8 3/4 (8.75)

Step-by-step explanation:

I divided 35 by 4 on a calculator to get 8.75

I know that 8.75 is the same as 8 3/4

So, say you're dividing 35 jellybeans with 3 of your friends (you're the fourth person, because you need some jellybeans too!)

Each would get 8 jellybeans. But there are 3 left over.

Split each jellybean into 4 parts.

Each of you would get 3/4 of one of the jellybeans. (three tiny parts of the total four tiny pieces)
