Answer:

-1/3

Step-by-step explanation:

Let the number be x.

x = 7x + 2

Add -7x on both sides.

x - 7x = 2

-6x = 2

Divide both sides by -6.

x = 2/-6

x = -1/3

Answer:

answer is 5.7,5.8,5.62,15.07,15.36,51.9

Answer: 5x + 1

Step-by-step explanation:

f(x) - g(x)

(3x + 2) - (-2x + 1)       Here you distribute the negative sign to (-2x + 1)

3x + 2 + 2x - 1            Here you combine like terms

5x + 1                         This is the answer.

Hey there! :)

Answer:

5.

Step-by-step explanation:

The pattern of this puzzle is to take the bottom two numbers of the triangle, find the sum, then divide by the top number. For example:

8 + 4 = 12 --> 12/3 = 4.

5 + 13 = 18 --> 18/6 = 3.

9 + 5 = 14 --> 14/2 = 7.

Therefore:

14 + 6 = 20 --> 20/4 = 5. The missing number is 5.

Answer:     2.345

Step-by-step explanation:

The square root of 5.5 is 2.345.

Answer: The answer is -3

Step-by-step explanation:

g(x)=kf(x)

g(-3)=kf(-3)

To solve this for k we will need to find the values for both g(-3) and f(-3).

g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.

g(-3)=-3

f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.

f(-3)=1

So our equation becomes:

g(-3)=kf(-3)

-3=k(1)

-3=k

So k=-3.

Hey there! :)

Answer:

56.7 kg.

Step-by-step explanation:

Use the density formula to solve for the mass:

D = m/V.

Rearrange in terms of mass, or 'm':

DV = m.

Solve for the volume:

0.06 × 0.9 × 1.5 = 0.081 m³.

Plug this into the equation along with the density:

700 × 0.081 = 56.7 kg.

Explanation: The population increases by the same amount each time, so the rate is constant, meaning we have linear growth. The slope of this line is 30.

The required graph of the function f(x) = {x when x < 1; 1 when x ≥ 1} has been shown.

As mentioned in the question we have to sketch the graph of the function f(x) = {x when x < 1; 1 when x ≥ 1}.

Since the given function is the piece vice function.

The graph of the piece vice function is will be the function y = x for range x < 1, and y = 1 for x greater equal to 1.

Thus, the required graph of the function f(x) = {x when x < 1; 1 when x ≥ 1} has been shown.

Answer: D

Step-by-step explanation:

A constant rate of change means that for every x, y increases the same amount.

In the situation "The amount a person pays for gas compared with the number of gallons purchased ," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid.  Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount.  This means it has a constant rate of change.

Answer:

a/h

Step-by-step explanation:

Using SOH CAH TOA. Sin = opposite/hypotenuse. Opposite of L is a, hypotenuse is h.

Answer:

The answer is given below

Step-by-step explanation:

a) Density is the ratio of mass to volume. Given that the mass of a cube = 2.331 g and the edge length (l) = 1.500 cm

The volume = l³ = 1.5³ = 3.375 cm³

Therefore, [tex]Density=\frac{mass}{volume}=\frac{2.331\ g}{3.375\ cm^3}=0.691\ g/cm^3[/tex]

b) The density of liquid A is 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Since Liquid A is more denser than liquid B, liquid B would float when mixed with liquid B. Liquid B is on top and liquid A is at the bottom.

C) If the cube is also dropped in the cylinder, since its density is more than the density of liquid B, liquid B would be on top, then the cube and lastly Liquid A would be at the bottom.

Answer:

x = 11/2 = 5^1/2 =5.5

Step-by-step explanation:

1/2(4x-12)=5

Multiply both sides by 2, the reciprocal of  2/1 =0.5

4x−12=5×2

Multiply 5 and 2 to get 10.

4x−12=10

Add 12 to both sides.

4x=10+12

Add 10 and 12 to get 22.

4x=22

Divide both sides by 4.

x = 22/4

Reduce the fraction  4/22 =5.5 to lowest terms by extracting and canceling out 2.

x = 11/2

Answer:

5.5

Step-by-step explanation:

1/2(4x-12)=5           Distributive Property

2x-6=5                   Open the Parentheses

2x=11                      Add 6 to Both Sides

1. 3 yellow and 9 red

Step-by-step explanation:

In the picture attached, the system is represented. The darker area shows all the points that are a solution to the system of inequalities.

The combinations can be rewritten as a coordinate pair, as follows:

1. 3 yellow and 9 red  -> (9,3)

2. 6 yellow and 4 red  -> (4,6)

3. 9 yellow and 3 red  -> (3,9)

4. 12 yellow and 8 red -> (8,12)

As we can see in the picture, only the first option is a solution.

Answer:

(a,c) ∪ (f, g)

Step-by-step explanation:

The function is:

Draw the slope of the tangent lines of several points on the curve,

Answer:

Step-by-step explanation:

The answer is A

Answer:

a) [tex]cos(\alpha)=-\frac{3}{5}\\[/tex]

b)  [tex]\sin(\beta)= \frac{\sqrt{3} }{2}[/tex]

c) [tex]\frac{4+3\sqrt{3} }{10}\\[/tex]

d)  [tex]\alpha\approx 53.1^o[/tex]

Step-by-step explanation:

a) The problem tells us that angle [tex]\alpha[/tex] is in the second quadrant. We know that in that quadrant the cosine is negative.

We can use the Pythagorean identity:

[tex]tan^2(\alpha)+1=sec^2(\alpha)\\(-\frac{4}{3})^2 +1=sec^2(\alpha)\\sec^2(\alpha)=\frac{16}{9} +1\\sec^2(\alpha)=\frac{25}{9} \\sec(\alpha) =+/- \frac{5}{3}\\cos(\alpha)=+/- \frac{3}{5}[/tex]

Where we have used that the secant of an angle is the reciprocal of the cos of the angle.

Since we know that the cosine must be negative because the angle is in the second quadrant, then we take the negative answer:

[tex]cos(\alpha)=-\frac{3}{5}[/tex]

b) This angle is in the first quadrant (where the sine function is positive. They give us the value of the cosine of the angle, so we can use the Pythagorean identity to find the value of the sine of that angle:

[tex]cos (\beta)=\frac{1}{2} \\\\sin^2(\beta)=1-cos^2(\beta)\\sin^2(\beta)=1-\frac{1}{4} \\\\sin^2(\beta)=\frac{3}{4} \\sin(\beta)=+/- \frac{\sqrt{3} }{2} \\sin(\beta)= \frac{\sqrt{3} }{2}[/tex]

where we took the positive value, since we know that the angle is in the first quadrant.

c) We can now find [tex]sin(\alpha -\beta)[/tex] by using the identity:

[tex]sin(\alpha -\beta)=sin(\alpha)\,cos(\beta)-cos(\alpha)\,sin(\beta)\\[/tex]

Notice that we need to find [tex]sin(\alpha)[/tex], which we do via the Pythagorean identity and knowing the value of the cosine found in part a) above:

[tex]sin(\alpha)=\sqrt{1-cos^2(\alpha)} \\sin(\alpha)=\sqrt{1-\frac{9}{25} )} \\sin(\alpha)=\sqrt{\frac{16}{25} )} \\sin(\alpha)=\frac{4}{5}[/tex]

Then:

[tex]sin(\alpha -\beta)=\frac{4}{5}\,\frac{1}{2} -(-\frac{3}{5}) \,\frac{\sqrt{3} }{2} \\sin(\alpha -\beta)=\frac{2}{5}+\frac{3\sqrt{3} }{10}=\frac{4+3\sqrt{3} }{10}[/tex]

d)

Since [tex]sin(\alpha)=\frac{4}{5}[/tex]

then  [tex]\alpha=arcsin(\frac{4}{5} )\approx 53.1^o[/tex]

Answer:  A

Since you already have an equation just put in how many stickers and erasers she wants to get: 0.35(2)+0.99(2)+0.59≤4.

Then you multiply: .35(2)=.70. .99(2)=1.98.

Then add: .70+1.98+.59=3.27, so yes she can since 3.27 is less than 4 so the answer is A

Answer:

A. yes, because the total will be $3.27

Step-by-step explanation:

0.35x + 0.99y + 0.59 ≤ 4

0.35(2) + 0.99(2) + 0.59 ≤ 4

0.70 + 1.98 + 0.59 ≤ 4

3.27 ≤ 4
