Answer:

2) 7/-8

Step-by-step explanation:

7/-8 because there is one negative meaning that the whole fraction will be negative. If there were two negatives, or none, it would be positive. The original fraction, -7/8, is a negative. Also, the actual numbers are equivalent as  well, 7/8 and 7/8.

Answer:

Option D: 2 is the correct answer.

Step-by-step explanation:

Given equation is:

2(x + 1) = 2x + ______

For balancing the equation, the variables and constants must be same on both sides of the equation.

Simplifying 2(x+1) gives us 2x+2

As 2x is already there, we will add 2 with it in the equation.

Hence,

Option D: 2 is the correct answer.

Answer:

5x and -7x

Step-by-step explanation:

they both end in the variable "x"

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

Answer:

(-1, 5)

Step-by-step explanation:

this is correct

The new coordinates of the vector (5,1) after rotating it 90° clockwise about the origin would be (-1,5).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Rotating a vector 90° clockwise in a 2D coordinate system can be accomplished by "flipping" the vector's x and y coordinates and then negating one of them.

In this case, the original x-coordinate is 5 and the y-coordinate is 1.

When we negate the x-coordinate and swap the positions of x and y, we get the new coordinates of (-1,5).

Step-by-step explanation:

This is because the sum of 2 sides of a triangle has to be greater than the side that was not used

Answer:

Angle ∠A = 93°'

Angle ∠B = 66.163°

Angle ∠C = 20.837°

Side a = 39.30337

Side b = 36

Side c = 14

Answer:

the expression is 21+18d

Step-by-step explanation:

Answer:

The answer is t(2844 + 1491) or t(4335)

Step-by-step explanation:

18 x 150 = 2700

18 x 8 = 144

2700 + 144 = $2844

21 x 65 = 1365

21 x 6 = 126

126 + 1365 = 1491

t = ? <--- t stays the same

1491 + 2844 = 4335

t(4225)

Answer:

The copper percentage = 64%

Step-by-step explanation:

Given

The percentage of copper metal can be determined using the formula

Copper percentage = [Copper quantity / Total quantity] × 100

                                  = [16 / 25] × 100

                                   = 0.64 × 100

                                   = 64%

Therefore, the copper percentage = 64%

Answer:

1. Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

2.Exact solution x = -0.376

Step-by-step explanation:

Solution:

First we have to write the Expanded Form of [tex]a^{2} . b^{3}[/tex], Let's do it.

1) [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

Hence,

Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

2) [tex]4^{5x} = 3^{x-2}[/tex]

Now, we have to find out the exact solution of the above equation:

In order to equate the exponents, we need to make sure the bases are same. Or we simply can use logarithm to solve the above equation.

So,

We are using logarithm to solve this equation.

Let's break this down:

[tex]4^{5x} = 3^{x-2}[/tex]

Taking log on both sides.

log[tex]4^{5x}[/tex] = log[tex]3^{x-2}[/tex]  

[tex]5xlog(4)[/tex] = [tex](x-2)log(3)[/tex]

Dividing both sides by log(4)

[tex]5x[/tex] = (x-2) [tex]\frac{log(3)}{log(4)}[/tex]

value of log(3) = 0.4771

value of log(4) = 0.6020

[tex]5x[/tex] = (x-2) [tex]\frac{log(0.4771)}{log(0.6020)}[/tex] =

5x = (x-2)0.792

5x = 0.792x - 1.584

by rearranging the equation, we get:

0.792x - 5x = 1.584

x(0.792 - 5) = 1.584

x(-4.208) = 1.584

x = -1.584/4.208

x = -0.376

Exact solution x = -0.376

Answer:

  30°

Step-by-step explanation:

The angle a line makes with the x-axis is arctan(slope). Here, that is ...

  angle with x-axis = arctan(√3) = 60°

So, the angle made with the y-axis is the complement of this:

  angle with y-axis = 90° -60° = 30°

Answer:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce.

The three components are Budget, time, and scope.

The relationship between them is an interdependent or triangular shape.

Step-by-step explanation:

The triple constraint represents the three constraints or inputs which control the project's capacity to produce. Budget, Scope and Time.

These 3 components are dependent to each other.

For example, if time is restricted then scope and budget will be affected. similarly.

The relationship between the three is that one of the two other components must decrease while one component increases for the project to succeed as expected.
