Answer 1
n is -1, and to get that you would need to have the equation 3(n)+7=4 since it says "three times (so parenthesis) the sum (plus sign) of a number 3(n)+7 and is means equal, so to 4.

A taco shop sells tacos and fountain drinks.
Nash bought two tacos and three fountain drinks
for $13. Everly bought four tacos and two
fountain drinks for $14. Write and solve a
system of equations to determine the cost of a
taco and a fountain drink.

Answers

The cost of one taco is $2, while the cost of one fountain drink is $3.

What are the system of equations that represent the question?

2t + 3f = $13 equation 1

4t + 2f = $14 equation 2

Where:

t = number of tacos bought f = number of drinks boughtHow many drinks were bought?

Multiply equation 1 by 2:

4t + 6f = 26 equation 3

Subreact equation 2 from equation 3

4f = 12

Divide both sides by 4

f = 12 / 4

f = $3

How many tacos were bought?

Subsistute for f in equation 1

2(t) + (3 x 3) = $13

2t + 9 = 13

2t = 13 - 9

2t = 4

t = 4/2

t = $2

Value (in billions) 2017 2018

Total assets $16. 20 $16. 80

Total liabilities $14. 60 $14. 80

Deposits $11. 90 $12. 20


From 2017 to 2018, borrowings by commercial banks changed by $ _ billion (round your answer to two decimal places).

From 2017 to 2018, owner’s equity for commercial banks changed by $_ billion (round your answer to two decimal places)

Answers

Answer:

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

Step-by-step explanation:

Total liabilities = deposits + borrowings

Borrowings = total liabilities - deposits

Borrowings in 2017 = $14.60 - 11.90 = $2.70 billion

Borrowings in 2018 = $14.80 - $12.20 = $2.60 billion

Borrowings from 2017-2018= 2.60 - 2.70 = $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017 = $16.2 - $14.6 = $1.6 billion

Owner’s equity in 2018 = $16.8 - $14.8 = $2 billion

Owner's Equity from 2017-2018= 2 - 1.6 = $0.4 billion

Hope this helps!

The Owner's Equity for commercial banks in  2017-2018 is $0.4 billion.

The given is,

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

What is the formula for the total liabilities?

Total liabilities = deposits + borrowings

So we have Borrowings = total liabilities - deposits

Borrowings in 2017

= $14.60 - 11.90

= $2.70 billion

Borrowings in 2018

= $14.80 - $12.20

= $2.60 billion

Borrowings from 2017-2018

= 2.60 - 2.70

= $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017

= $16.2 - $14.6

= $1.6 billion

Owner’s equity in 2018

= $16.8 - $14.8

= $2 billion

Owner's Equity from 2017-2018

= 2 - 1.6

= $0.4 billion

What is the y-value of the vertex of the function f(x)=−(x+8)(x−14)?

Answers

Answer:

f(x) = -(x + 8)(x -14)

= -(x2 - 112 - 6x)

= -x2 + 6x + 112 --- (1)

We know the graph of an equation y = ax2 + bx + c where a ≠ 0 is a parabola. The parabola opens upwards if a > 0 and opens downwards if a < 0. The vertex of the parabola is the point where the axis and parabola intersect. Its x coordinate x = -b/2a and its y coordinate is found out by substituting x = -b/2a in the parabola equation.

The parabola given in the problem statement has a negative coefficient of x2 and hence it is a parabola which opens downwards. Also for the equation

a = -1, b = 6 and c = 112. Therefor the x-coordinate of the vertex is

x = -b/2a

= -(6)/[2(-1)]

= 3

Substituting the value of x = 3 in equation (1) we get,

Now y = -(3)2 + 6(3) + 112

= -9 + 18 + 112 = 121

So the vertex point coordinates are (3, 121) and the y value is 121.

If the angles of measures of angles X, Y, and Z are neither law of sine and cosine can be used to solve the triangle.

What is the law of cosines and sines?

The law of cosines can be used to determine the measures of the triangle if the angles are known. The law is given by:

a² = b² + c² - 2bc*cosA

a,b,c are the sides and A, B, C are the angles.

The law of sines are used to determine the measures of the triangle if the angles are known. The law is given by:

The volume of a box is 124.4 in3. Find the volume of a larger, similarly shaped box that has a scale factor of 4. Round your answer to the nearest tenth.

Answers

Using the scale factor, the volume of the larger similar shaped box is 497.6in³.

What is a Scale Factor?

A scale factor is simply the ratio of the corresponding sides of two similar objects. A scale factor of 4 simply means that the new shape is multiply four times the size of the original shape.

Given the data in the question;

Volume of original box V° = 124.4in³Scale factor SF = 4Volume of the larger box V = ?

Since scale factor of 4 means that the new shape is multiply four times the size of the original shape.

Volume of the larger box V = V° × SF

V = 124.4in³ × 4

V = 497.6in³

Therefore, using the scale factor, the volume of the larger similar shaped box is 497.6in³.

Reflect circle A over the y-axis.

Answers

Answer:

A

Step-by-step explanation:

To show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have two circles:

Circle A has a center of (2, 3) and a radius of 5

Circle B has a center of (1, 4) and a radius of 10

The standard circle's equation can be written as:

(x - h)² + (y - k)² = r²

The equation for circle A:

(x - 2)² + (y - 3)² = 5²

The equation for circle B:

(x - 1)² + (y - 4)² = 10²

To show that circle A is similar to circle B:

It is required to perform the geometric transformation:

Dilate circle A by a scale factor of 2.

The radius of circle A is 5 units and after dilation by a scale factor of 2, the radius of the circle becomes 10 which is the radius of circle B.

Thus, to show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

B. x= -1
0 C. x= -3
D. x= 2
E. x = 3

Answers

Answer:

  E.  x = 3

Step-by-step explanation:

The equation can be factored by considering the factors of the product of the first and last coefficients. Those factors must have a sum equal to the middle coefficient.

  (2)(-3) = -6 = (-6)(1) = (-3)(2) = ... other factors with positive sums

The sums of the factor pairs shown are -5 and -1. We're interested in the factor pair {-6, 1}. Replacing the middle term coefficient with the sum of these, we can write the equation in a way that lets us factor pairs of terms.

  2x² -6x +x -3 = 0 . . . . . . . . replace -5x with -6x+1x

  2x(x -3) +1(x -3) = 0 . . . . . . factor pairs of terms

  (2x +1)(x -3) = 0 . . . . . . . . . complete the factoring

Solutions are the values of x that make these factors zero:

  2x +1 = 0   ⇒   x = -1/2

  x -3 = 0   ⇒   x = 3

Additional comment

A number of methods are used to find the factors of a quadratic with a leading coefficient other than 1. When the coefficients are small integers, this is one of the more straightforward methods: actually listing and examining the pairs of factors of "ac." If "ac" has a large number of divisors, other methods may be more practical.

Step-by-step explanation:

First I will mark all the Information given to us:

Angle 1: 52 Degrees

Angle 2: 90 (Marked by the box) Degrees

Angle 3: 180-(90+52) Triangle Angle Sum Therom

Simplified Angle 3: 38 Degrees

Height: 10

Base: X
Hypo: ? (we will call this y)

In order to solve this problem we must use basic trig functions such as sin, cos and tan.

I will be applying sin for the degree measure of 52 as it is applicable there.

(Sin for refrence sin(angle measure)= side opposite to angle/hypo)

So this would be in our case:

Sin(52)=10/y

Simplify

y sin(52) = 10

y = 10/sin(52) (use a calculator make sure sin is in degrees not radians)

y=10/0.78801

y=12.69018 (We have our hypo value)

We can now apply a²+b²=c²

a²+10²=12.69018²

a²+100=161.040668432 (Calculator)

a²=61.040668432

a=√61.040668432 (calculator)

a=7.81285277168

Slope of line:                                                                                    

Two points that lie on line: (0, 3) and (-5, 0)
