Answer:

B is correct. Your starting amount is 210$ And you're taking away 15$ each time she uses the club,x.

Step-by-step explanation:

Answer:

The linear function model the situation is b = 210 - 15x .

Option (B) is correct .

Step-by-step explanation:

Let us assume that the number of times giselle uses the club be x .

As given

giselle pays $210 in advance on her account at the athletic club.

Each time she uses the club,$15 is deducted from the account.

Let suppose that the money left after giselle uses the club x times is b .

Than the equation becomes

Money left = Amount pay in advance - Deducted amount × Number of times  giselle uses the club .

Put all the values in the above

b = 210 - 15 × x

b = 210 - 15x

Therefore the linear function model the situation is b = 210 - 15x .

Option (B) is correct .

Step-by-step explanation:

take the percent of each and multiply it by the years. do it for both. and add the 12000. then subtract both from each other and you get 450.

Answer: No.

Step-by-step explanation:

They aren't equal because using the order of operations, the two in 7n-2 is subtracted from 7n. In 2-7n, they are subtracting 7n from 2, which would give a totally different answer.

Answer:

no they are not the same or equal. this is because the first part of the expression 2 is the number that is negative while 7n is positive. in the second half of the expression 2 is positive and 7n is negative.

The Triangle EHL and MPE by HL Congruence Rule.

Two triangles are said to be congruent if their sides and angles are the same length. Two triangles can thus be stacked side by side and angle by angle.

Two triangles are said to be congruent if their sides are the same length, their angles are the same measurement, and they may be superimposed on each other.

As, from the figure in Triangle EHL and MPE

EH = MP

EL = ME

<EHL = < MPE = 90

As, If the hypotenuse and a leg of one right triangle are congruent with the hypotenuse and leg of another right triangle, the triangles are congruent.

So, the Triangle EHL and MPE is Congruent by HL Congruence Rule.

Answer:

You must know the shape of the graph y = x². Its chart is in the form of an upward parabola. The shape of the graph y = -x² is the same except that it is downward. Finally, to draw the shape of the graph y = -x² + 9, we need to move the previously mentioned graph 9 units upwards.

The formula for the vertex length of a parabolic chart is as follows: x= -b/(2a) b=0 , a= 1 → x= 0, y=-(0)²+9=9

vertex: (0,9)

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = - 5 → (1)

2x - 5y = 13 → (2)

Subtracting (1) from (2) term by term will eliminate the x-0 term

0 - 5y - y = 13 - (- 5) , that is

- 6y = 18 ( divide both sides by - 6 )

y = - 3

Substitute y = - 3 into either of the 2 equations and solve for x

Substituting into (1)

2x - 3 = - 5 ( add 3 to both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

solution is (- 1, - 3 )

Answer: it will cost $3.768 to fill the cone to its full capacity.

Step-by-step explanation:

The frozen yoghurt is filled in cone shaped cups. The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Where

h represents the height if the cone.

r represents the radius of base of the cone.

π is a constant whose value is 3.14

From the information given,

r = 3 inches

h = 5 inches

Volume = 1/3 × 3.14 × 3² × 5 = 47.1inches³

If customers pay $0.08 per cubic inch, it means that the amount that it would cost to fill the cone to its full capacity is

0.08 × 47.1 = $3.768

it will cost $3.768 to fill the cone to its full capacity.

Answer:

If all three digits need to be the same (I assume that's what aaa means) it's 333

Step-by-step explanation:

For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:

X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)

So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.

Answer:

Her net income is more than $120.

Answer:

6%/year

Step-by-step explanation:

Solving our equation

r = 300 / ( 1000 × 5 ) = 0.06

r = 0.06

converting r decimal to a percentage

R = 0.06 * 100 = 6%/year

The interest rate required to

accumulate simple interest of $ 300.00

from a principal of $ 1,000.00

over 5 years is 6% per year.

Answer:

l = 6.00

Step-by-step explanation:

So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so

3l = 2l + 2(3), so l = 6.

¿Cumplirá Amelia con lo que se ha propuesto?

Amelia no cumple con lo que se ha propuesto, porque:

56,4 ÷ 2 = 28,2 ← 1 cucharadita

28,2 + 28.2 = 56,4 + 28,2 = 84.6 Cal ← 3 cucharaditas

84.6 Cal + 17 Cal azúcar = 101,6 Cal

101,6 Cal + 180 Cal pan = 281,6 Cal

Lo que se ha propuesto Amelia = 260 Cal

Lo que está consumiendo = 281 Cal

Answer:

y>2x+8:  Dashed    x+1/2y is less than or equal to 12:  Solid      y is greater than or equal to 2/3x-6:  Solid     -4x+2y<10:  Dashed

Step-by-step explanation:

If there is a < or > sign, it is dashed, because the answer you get is not part of the solution (it is either less than or greater than the solution). If it is a less than or greater than or equal to sign (with the line under it) the line will be solid because the answer you get is part of the solution.

The boundary line will not be included in the solution set. Therefore, the boundary line will be dashed. The table shows the following:

Dashed if the boundary line is not included in the solution set.

Solid if the boundary line is included in the solution set.

The inequalities that will have a dashed boundary line are:

y > 2x + 5

x + y ≤ 12

The inequalities that will have a solid boundary line are:

y ≤ 2x - 6

-4x + 2y - 10 ≤ 0

Here is an explanation of why each inequality will have the boundary line that it does:

y > 2x + 5

This inequality is not equal to 2x + 5, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.

x + y ≤ 12

This inequality is equal to x + y ≤ 12, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.

y ≤ 2x - 6

This inequality is equal to y ≤ 2x - 6, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.

-4x + 2y - 10 ≤ 0

This inequality is not equal to -4x + 2y - 10, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.
