Answer:

D. x=1

Step-by-step explanation:

Solve  :    x-1 = 0

Add  1  to both sides of the equation :

                     x = 1

x = 1 for equation 5x - ( 4x - 1) = 2.

An equation is a mathematical statement that shows that two mathematical expressions are equal. It may have one variable, two, three and so on.

For given equation,

5x - ( 4x - 1) = 2

This is a equation in one variable which can be solved by transposing the terms.

Firstly, Solving the parenthesis,

5x-4x+1=2

Then, Solving the like terms.

x+1=2

To calculate the value of x, subtract 1 from both the sides.

x+1-1=2-1

x=1

Thus, the value of x is 1. So, option d) is correct.

Answer:

6 root 2

Step-by-step explanation:

Pythagous Therom

A^2 = B^2 + C^2

B^2 = C^2 - A^2

B^2 = 36 - (2 Root 3)^2

B^2 = 24

B = 2 root 6

Base x Height / 2 for area of Triangle

2 root 3 x root 24 = 12 root 2

12 root 2 / 2 = 6 root 2

The right triangle is the one where one of the angles is a right angle (90 degrees) or two of the sides are perpendicular.

In [tex]\Delta[/tex] ABC

h² = 6² -(2√3)²

h² = 36-2² × √3²

h² = 36- 4× 3

h² = 36- 12

h² = 24

h =√24

h = 2√6 cm

Area  = [tex]\frac{1}{2}[/tex]× BC × h

         = [tex]\frac{1}{2}[/tex] × 2√3 ×  2√6

        = 2√18

        = 6√2

compare it with A= K√2 So K= 6

The solution is $ 96

The cost of 40 pints of ice cream is given by the equation A = $ 96

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 40 pints of ice cream be A

Now , the equation will be

The cost of 6 pints of ice cream = $ 14.40

So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6

Substituting the values in the equation , we get

The cost of 1 pint of ice cream = 14.40 / 6

The cost of 1 pint of ice cream = $ 2.40

Now ,

The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream

Substituting the values in the equation , we get

The cost of 40 pints of ice cream A = 40 x 2.40

The cost of 40 pints of ice cream A = $ 96

Therefore , the value of A is $ 96

Hence , the cost is $ 96

Answer: (-8,6)

Step-by-step explanation:

Question: What is the image of (-4,3)(−4,3) after a dilation by a scale factor of 22 centered at the origin?

Dilation: multiply each coordinate

(x,y)\rightarrow (2x,2y)

(x,y)→(2x,2y)

Dilations multiply by scale factor

(\color{red}{-4},\color{blue}{3}) \rightarrow (2\cdot \color{red}{-4},2\cdot \color{blue}{3})=\mathbf{(-8,6)}

(−4,3)→(2⋅−4,2⋅3)=(−8,6)

This was on my delta math so i hope this helps

The image of the point (- 4, 3) after dilation will be (-8,6).

Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.

Given point is  (-4, 3). The dilation of the point will be calculated as below:-

Dilation:- multiply each coordinate.

(x,y)→(2x,2y)

Dilations multiply by a scale factor

(−4,3)→(2⋅−4,2⋅3)=(−8,6)

She need to buy 10 oranges of $6.40.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given that grocery store sells a bag of 7 oranges for $4.48. If Khloe spent $6.40 on oranges, then

We have to do as $4.48 divide by 7
