The value of x in the isosceles triangle is 9.25.

An isosceles triangle is a polygon that has three sides. The opposite length have the same length and equal angles.  has two opposite sides. If the two angles are equal , it means the triangle is an isosceles.

Th perimeter of an isosceles triangle is the sum of the length of the three sides of the triangle.

Perimeter = (2 x length of leg) + base

43 = (2x x) + 2x - 6

43 = 2x + 2x - 6

43 = 4x - 6

43 - 6 = 4x

37 = 4x

x = 37 / 4

x = 9.25

If the domain of the function f(x) = 2x + 1 is {-2 ≤ x ≤ 3}, an integer which is not in the range is: a) -4.

In Mathematics, a range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range refers to the set of all possible output numerical values (real numbers), which are shown on the y-axis of a graph.

When x = -2, the range of this function f(x) = 2x + 1 is given by:

f(-2) = 2(-2) + 1

f(-2) = -4 + 1

f(-2) = -3

When x = 3, the range of this function f(x) = 2x + 1 is given by:

f(3) = 2(3) + 1

f(3) = 6 + 1

f(3) = 7

Therefore, the range of this function is -3 ≤ y ≤ 7 and as such, -4 is an integer that is not within the range as shown in the number line attached below.

Answer:  only one solution

Step-by-step explanation:

9x + 2/3 = 3x + 3 is a linear equation.

Linear equations only have one solution as the lowest power in numbers is 1.

9x + 2/3 = 3x + 3

9x - 3x = 3 - 2/3

3x = 7/3

x = (7/3)/3

Step-by-step explanation:

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of AgCl when treated with excess ag⁺  is 17.2%

The percent of chloride can be calculate as follow:

Mass of AgCl precipitated = 1.750 g

Molar mass of AgCl = 143.32 g/mol

Molar mass of Chlorine atom = 35.45 g/mol

Asume, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.

To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:

In 143.32 g of silver chloride, mass of chlorine present is 35.45 g

So, in 1.3487 g of silver chloride, mass of chlorine present will be =

35.45g/143.32 g * 1.750 g = 0.43 g

To calculate the percentage composition of chlorine in pure chloride compound, as follows:

Mass of pure chloride compound = 2.500 g

Mass of chlorine = 0.43 g

% Chlorine = 0.43/2.5 *100

% Chlorine = 17.2 %

Therefore, the mass percentage of chloride in pure chloride compound is 17.2%

The expression represents the current price of milk is 3 + y in dollars

The initial price of a gallon of milk = $2.65

The price rose y dollars after the last hurricane

Then the expression will be

2.65 + y

Then the price dropped $0. 15

2.65 + y - 0.15

Add the terms

2.65 + y - 0.15 = 2.5 - y

later rose again by $0. 5

2.5 + y + 0.5

Add the terms in the expression

2.5 + y + 0.5 = (2.5 + 0.5) + y

= 3 + y

Current price of milk = 3 + y in dollars

Hence, the expression represents the current price of milk is 3 + y in dollars

Answer:

13x-12y+6xy

Step-by-step explanation:

To  make this easier, we can rearrange these terms, and get

5x+8x-12y+2xy+4xy.

x and y just represent variables, so we can combine 5x and 8x to get 13x, and we can combine 2xy and 4xy to get 6xy.

Now we have 13x-12y+6xy, and nothing else can be combined.

The given expression 7x - y = -9 in the slope intercept form can be represented as y = 7x + 9.

The expression given to us is -

7x - y = -9

We have to represent this in the slope intercept form.

The slope intercept form can be represented as -

y = mx + c

where, y = y coordinate of the line

           m = slope of the line

            x = x coordinate of the line

            c = y intercept of the line

Thus, representing the given expression in the slope intercept form, we have

7x - y = -9

=> -y = -7x - 9

=> y = 7x + 9

Thus, the given expression in the slope intercept form can be represented as y = 7x + 9.

Answer:

x = 8

Step-by-step explanation:

since the triangle is isosceles then the 2 legs are congruent, that is both 4x - 3

the perimeter is the sum of the 3 sides , that is

x + 4x - 3 + 4x - 3 = 66

9x - 6 = 66 ( add 6 to both sides )

9x = 72 ( divide both sides by 9 )

Marcia has written the expression 0. 75p to represent the sale price. The best description for her expression is she multiplied p by 0.25 then subtracted that from p.

How to express the sale price?

The sale price is the price after discount. Discount is the amount by which the origin price of an item is reduced. In this case, Marcia wants to buy a television with the origin prices is p dollars. The store is offering 25% discount.

p = the origin price

25% discount = 0.75p

The equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

y + 3 = -12/7(x - 5)

Given, a line that passes through the points (5, −3) and (−2, 9).

Now, we have to find the equation of the line in point-slope form.

As, we know to find the equation of a line,

(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)

Now, using the above formula, we get

(y + 3)/(x - 5) = (-3 - 9)/(5 + 2)

(y + 3)/(x - 5) = -12/7

On cross-multiplying, we get

y + 3 = -12/7(x - 5)

Hence, the equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

y + 3 = -12/7(x - 5)
