Use the point-slope formula to write an equation of the line through the points (0,3)(11,4)

butalik [34]

Points : (0,3)(11,4)

Slope formula : M= y2-y1/x2-x1

M= 4-3/11-0

M= 1/11

Equation of a line is : y= mx+b

Now get one pair of point to solve for b .

(11,4)

4= 1/11(11)+b

4= 1+b

4-1=b

3=b

Equation y=mx +b

Y= 1/11x+3

An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.

Elina [12.6K]

Answer:

The equation that models the situation is $A(t) = 13(1.0078)^t$

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

$A(t) = A(0)(1+r)^t$

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that $A(0) = 13, r = 0.0078$

Write an equation to model the situation.

$A(t) = A(0)(1+r)^t$

$A(t) = 13(1+0.0078)^t$

$A(t) = 13(1.0078)^t$

The equation that models the situation is $A(t) = 13(1.0078)^t$

A store in Minnesota advertises that on a holiday, everything is 20% off. A person buys shoes for $40 and socks for $10. In Minn

posledela

The final price is $ 40

Solution:

A store in Minnesota advertises that on a holiday, everything is 20% off

Discount = 20 %

A person buys shoes for $40 and socks for $10

Therefore, Total price before discount is given as:

Total price = 40 + 10 = 50

Therefore,

Total price before discount = $ 50

Discount = 20 %

Therefore, discount price is 20 % of 50

$Discount\ price = 20 \% \times 50\\\\Discount\ price = \frac{20}{100} \times 50\\\\Discount\ price = 10$

Thus the discount price is $ 10

Final price is given as:

Final price = Total price before discount - discount price

Final price = 50 - 10 = 40

Thus the final price is $ 40
