Answer: Part A An equivalent expression of 4(a + 12) + 5(8) is 4a + 4(12) + 5(8)

or 4a + 48 + 40

Part B:  using 15 in place of a,  the Rodriguez family spent $148 on tickets.

Step-by-step explanation: We can use the distributive property to create equivalent expressions.

Part B:  Substitute 15 in place of a and do the calculations

4(15 + 12) + 5(8)

60 + 48 + 40

148

The time taken to grow to $8000 is 17 years and 4 months.

The formula used to find the time compounded continuously.

t = ln(A/P) / r

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $4000

A = $8000

r = 4%

The formula used:

t = ln(A/P) / r

t = ln(8,000/4,000) / 0.04

t = 17.329 years

This means,

= 17 years 4 months

Thus,

The time taken to grow to $8000 is 17 years 4 months.

Answer:

Answer:

Part A:

c = 1.15p

c(2) = $2.30

Part B:

c = 0.90p

Part B:

Step-by-step explanation:

Linear Models

Candy's Sweets Company charges $1.15 per pound to ship candy.  This represents a proportional relationship between the pounds of candy and the cost.

Part A: If each pound costs $1.15, then p pounds cost $1.15p. Then the equation of the cost c is:

c = 1.15p

The cost of shipping p=2 pounds of candy is:

c = 1.15*2 = 2.30

c = $2.30

Part B: When the company reduces the cost by $0.25 per pound, the new unit cost is $1.15 - $0.25 = $0.90 per pound.

The new equation to determine the total cost for p pounds of candy is:

c = 0.90p

Answer:

The surface area of this cylinder is 3545[tex]\frac{1}{7}[/tex] cm²

Step-by-step explanation:

The formula of the surface area of the cylinder is

Let us use the rules above to solve the question

∵ The base of the cylinder is a circle

∵ The perimeter of the circle = 2 π r

∵ The radius of the cylinder is 12 cm

∴ r = 12

∴ The perimeter of the base = 2 (12) (π)

∴ The perimeter of the base = 24π cm

∵ The height of the cylinder is 35 cm

∴ h = 35 cm

→ By using the rule of the lateral area above

∵ The lateral area = 24π × 35

∵ π = [tex]\frac{22}{7}[/tex]

∴ The lateral area = 24 × [tex]\frac{22}{7}[/tex] × 35

∴ The lateral area = 2640 cm²

∵ The area of the circle = π r²

∴ The area of the base = [tex]\frac{22}{7}[/tex] × (12)² = [tex]\frac{22}{7}[/tex] (144) = 452[tex]\frac{4}{7}[/tex] cm²

→ By using the rule of the surface area above

∴ The surface area = 2640 + 2(452[tex]\frac{4}{7}[/tex]) = 3545[tex]\frac{1}{7}[/tex] cm²

∴ The surface area of this cylinder is 3545[tex]\frac{1}{7}[/tex] cm²

Answer:

Step-by-step explanation:

8/3x=4+5/3x

8/3-5/3x=4

x=4

Answer: y=-1/3x+5

Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get  -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!

Answer:

y =1, 1.5, 2, 2.5, 3

Step-by-step explanation:

Plug in the values of x into the equation for y.

For example when x is 0, plug in 0 into the equation

0.5x + 1 = y

0.5(0) + 1 = 1

So, y = 1

To find the other values of y, plug in the designated value of x into the equation.

Answer:

1,2,3,6 are congruent

Step-by-step explanation:

Draw a point B, then draw any two other points D and E. The rays BD and BE are essentially arrows that both start at B and pass through D and E, respectively. See the attached sketch. Note that the points D and E need not lie on a circle like the dotted one in the sketch; they can be placed anywhere along the ray.

Then:

• (I) is sometimes true. Rays can be parallel as long as they are collinear, meaning the three points B, D, and E would need to lie on the same line. (The first sketch shows one example)

• (II) is always true.

• (III) is sometimes true, if the angle the two rays form is a right angle. (The second sketch shows one example)

• (IV) is never true, because B would have to lie on the circle itself. The center does not.

Without knowing what Damiana's/Valeria's drawing looks like, the most we can do is rule out C and D.

Answer:

[tex]=\frac{2x^3+x^2-11x+14}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]

Step-by-step explanation:

Step 1: Factor [tex]x² + 2x - 8: (x - 2) (x + 4)[/tex]

[tex]=\frac{x}{x+4}+\frac{x-1}{x+2}+\frac{3}{\left(x-2\right)\left(x+4\right)}[/tex]

Step 2: Find the Least Common Multiplier of  [tex]x + 4, x - 2, (x + 4), (x - 2)[/tex]

= [tex](x + 4) (x + 2) (x - 2)[/tex]

Step 3a: Conform the fractions based on the LCM (Least Common Multiplier)

= [tex]\frac{x\left(x+2\right)\left(x-2\right)}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}+\frac{\left(x-1\right)\left(x+4\right)\left(x-2\right)}{\left(x+2\right)\left(x+4\right)\left(x-2\right)}+\frac{3\left(x+2\right)}{\left(x-2\right)\left(x+4\right)\left(x+2\right)}[/tex]

Step 3b: The denominators are equal, so combine the fractions.

[tex]=\frac{x\left(x+2\right)\left(x-2\right)+\left(x-1\right)\left(x+4\right)\left(x-2\right)+3\left(x+2\right)}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]

Step 4: Expand [tex]x(x + 2)(x - 2) +(x-1)(x+4)(x-2) + 3(x-2)[/tex]

[tex]=\frac{2x^3+x^2-11x+14}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]

Answer:

a. y = 2x + 1: Not from x to y

b.1 = 2y – 4x: Not from x to y

c. y^2 – 1 = x: This is a function from x to y

Step-by-step explanation:

We are to determine whether or not the equations are function from x to y

Given the function y = f(x)

y is a dependent variable while the input variable is an independent variable. So we can say y is a function from y to x.

Also x = f(y) can be expressed as equation of a function from x to y i.e x is dependent and the input variable is independent

From tthe following options, the equation that is a function from x to y is

y² – 1 = x

This can also be written as x = y² – 1 where f(y) is y² – 1

The rest are not a function of x to y but otherwise unless re-written

Answer:

The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].

Step-by-step explanation:

Mathematically speaking, lines are represented by following first-order polynomials of the form:

[tex]y = b + m\cdot x[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]m[/tex] - Slope.

[tex]b[/tex] - Intercept.

The gradient of the function is represented by the first derivative of the function:

[tex]y' = m[/tex]

Then, we conclude that the gradient of the staight line is the slope. According to Euclidean Geometry, a line can be form after knowing the locations of two distinct points on plane. By definition of secant line, we calculate the slope:

[tex]m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)

Where:

[tex]x_{A}[/tex], [tex]y_{A}[/tex] - Coordinates of point A.

[tex]x_{B}[/tex], [tex]y_{B}[/tex] - Coordinates of point B.

If we know that [tex]A(x,y) = (2,6)[/tex] and [tex]B(x,y) = (6,12)[/tex], then the gradient of the straight line is:

[tex]m = \frac{12-6}{6-2}[/tex]

[tex]m = \frac{6}{4}[/tex]

[tex]m = \frac{3}{2}[/tex]

The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].
