Malcolm and Nick opened savings accounts with different beginning deposits. Each week, they both deposit the same amount into their accounts. This graph shows the amount of money in Malcolm’s account.

If, on the fifth week, Nick has $120 in his savings account, which equation shows the amount of money in Nick’s account?

A. y = 10x + 40
B. y = 10x +70
C. y = 20x + 40
D. y = 20x + 70

Answers

Answer 1

Answer:

Step-by-step explanation:

To solve this equation you use the y=mx+b format

Considering that the graph starts at 40 (b) and increase 10 every time that means that the m is 10

Sorry that probably made no sense

Find the percent change:

$350 to $400

Answers

Answer:

14.29% increase

Hope this helps!

Step-by-step explanation:

The formula for this would be:

New value - Old value

Then divide the answer by the old value

Finally multiply it by 100

So it should be $400 - $350 which is $50

Then $50 ÷ $400 which is 0.125

Finally do 0.125 × 100 which is 12.5

So there has been a 12.5% increase

A company rents out 11 food booths and 22 game booths at the county fair. The fee for a food booth is $125 plus $6 per day. The fee for a game booth is $80 plus $10 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.

Answers

Answer:

$3135 + $286d

Step-by-step explanation:

Given that:

Food booth = 11

Game booth = 22

Let number of days = d

Food booth rent = ($125 + 6d) * 11

Game booth rent = ($80 + 10d) * 22

Food booth = $1375 + $66d

Game booth = $1760 + $220d

Amount company is paid :

Food booth rent + game booth rent

($1375 + $66d) + ($1760 + $220d)

$(1375 + 1760) + $(66d + 220d)

$3135 + $286d

What is triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

Here, given that,

An equilateral triangle with side length 1 cm .

we know,

area of An equilateral triangle

=√3/4×side²

so, the area of the triangle = √3/4×1

=√3/4 cm^2

hence, the area of the triangle is √3/4cm^2.

What is 12 = 1 + a/1 -a?

Answers

Answer:

There is no solution

Step-by-step explanation:

There are no values of (a) that make the equation true.

Answer:

a = 11/13

Step-by-step explanation:

Multiply both sides by 1 - a

12(1 - a) = 1 + a

= 12 - 12a = 1 + a

Subtract 12 from both sides

= -12a = -11 + a

Subtract a from both side

-13a = -11

Divide by -13 each side

-13a/13 = -11/-13

= a = 11/13

For the given equation of the graph, the slope is 3 and the y-intercept is 7.

An algebraic equation known as a linear equation depicts a straight line on a graph. This equation has one as the greatest power of the variable or variables at play. In other words, no exponentiation or other mathematical action is performed on the variables in a linear equation.

The general equation of the straight line is,

y = mx + c

Here, m is the slope and c is the y-intercept.

Compare the given equation with the general equation of the line,

y = mx + c

y = 3x + 7

Therefore, the slope is 3 and the y-intercept is 7.
