I open a savings account with 25$. I deposit the same amount from my check each month. After 6 months, I have 235$ in my savings

account. Assuming a constant rate of change, write a linear function that represents the amount of money in the savings account s(x) , as a function of the number of months x​

Answer:

s(x) = 25 + 35x

Step-by-step explanation:

We calculate the difference between the initial deposit and 6 months.

235 - 25 = 210

We calculate the amount per month of the deposits.

210 / 6 = 35

s(x) = 25 + 35x

This recipe makes 4 portions of potato soup.
Dominik [7]

Answer:

120 ml oil

150g onions

1.2 kg potatoes

1.5 litres milk

Step-by-step explanation:

The revipe serves 4 people, but Richard wants to serve 12 people. This is 3x the number of people intended.

So, multiply all the fiven ingredients by 3 as well.

Oil = 40ml x 3 = 120ml

Onions = 50g x 3 = 150g

Potatoes = 400g x 3 = 1200g = 1.2 kg

Milk = 500ml x 3 = 1500ml = 1.5 litres

Hope this helps

when you reverse the digits in a certain two-diget number you increase it value by 27. What is the number if the sum of its digi
Fynjy0 [20]
The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is =  x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27    ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y

9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4

x=5-y
x=5-4=1

The number is: 10x+y=10(1)+4=14

Answer: the number is 14

The legs if an isosceles triangle are (3x^2+4x+2) inches and the base is (4x-5) inches. Find the perimeter of the triangle
alexdok [17]

Answer:

P=(6x^2+12x-1)\ in

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

so

The perimeter of triangle is equal to

P=2(3x^2+4x+2)+(4x-5)

Eliminate parenthesis

P=6x^2+8x+4+4x-5

Combine like terms

P=(6x^2+12x-1)\ in

Graph a system of equations to solve log (−5.6x + 1.3) = −1 − x. Round to the nearest tenth.
const2013 [10]

From the least to the greatest, the solutions are x ≈ -2.1 and x ≈ 0.2

the answers are -2.1 and 0.2.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have two systems of the equation:

y = log (−5.6x + 1.3)

y  = −1 − x

After plotting the above equation on the graph we will see two intersections point:

(-2.12, 1.12) and (0.221, -1.221)

So the least value is x = -2.12 ≈ -2.1

The greatest value is x = 0.221 ≈ 0.2

Thus, from the least to the greatest, the solutions are x ≈ -2.1 and x ≈ 0.2

the answers are -2.1 and 0.2.
