Question
F(x) = 18x + 13, find F(4)
Solution 1

Answer:

f(4) = 85.

Step-by-step explanation:

When you substitute the 4 into the x and solve for f(4), all that means is that every x in the equation becomes 4.  There's only one on the right side: the 18x.  This becomes 18*4, or 72, which is then added to 13, to get 85.

Solution 2

Answer:

F(4) = 85

Step-by-step explanation:

F(x) = 18x + 13

F(4) = 18(4) + 13

F(4) = 72 + 13

F(4) = 85

Question
Lauren deposited x dollars into a savings account that pays 2.75% annual simple interest. After one year, Lauren's account had earned $30.25 in interest. What was the amount of Lauren's original deposit?
Solution 1

Answer:

The amount of Lauren's original deposit is $1100.

Step-by-step explanation:

The formula of the simplest interest is I = P r t, where

  • P is the original amount
  • r is the interest rate in decimal
  • t is the time

∵ Lauren deposited x dollars into a savings account that pays

   2.75% annual simple interest.

∴ P = x dollars

∴ r = 2.75

→ Divide it by 100 to change it to decimal

∵ 2.75 ÷ 100 = 0.0275

∴ r = 0.0275

∵ After one year, Lauren's account had earned $30.25 in interest

∴ t = 1 year

∴ I = 30.25 dollars

→ Substitute them in the rule above

∵ 30.25 = x(0.0275)(1)

∴ 30.25 = 0.0275x

→ Divide both sides by 0.0275

∴ 1100 = x

∴ The amount of Lauren's original deposit is $1100.

Question
Find the slope and write in slope intercept form. (6,77) (7,80) (7,83) (8,87) (9,92)
Solution 1
The slope is 3. Y - 77 = 3 ( x - 6 ) is the equation in point slope form.
Question
Solve the following system of equations for x and y. −7x + 3y = 22 −3x - 4y = −4
Solution 1
* -21x + 9y = 66
21x + 28y = 28
37y= 94
y= 94/37
* -3x - 4y = -4
-3x - 4(94/37)= -4
-3x = -4 + (4*(94/37))

Question
Write a function in the form y=mx+b for the line that contains the points (-6.4, -2.6 )and (5.2,9)
Solution 1

Answer:

The function in the form y = mx+b will be:

y = x + 3.8

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the points

  • (-6.4, -2.6)
  • (5.2, 9)

Determining the slope between (-6.4, -2.6 )and (5.2,9)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-6.4,\:-2.6\right),\:\left(x_2,\:y_2\right)=\left(5.2,\:9\right)

m=\frac{9-\left(-2.6\right)}{5.2-\left(-6.4\right)}

Refine

m=1

substituting (5.2, 9) and m = 1 in the slope-intercept form of the line equation

y = mx+b

9 = 1(5.2) + b

b + 5.2 = 9

b = 9 - 5.2

b = 3.8

Therefore, the value of x = 3.8

now substituting b = 3.8 and m = 1 in the slope-intercept form of the line equation

y = mx+b

y = 1(x) + 3.8

y = x + 3.8

Therefore, the function in the form y = mx+b will be:

y = x + 3.8

  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

-25x + 14 > 20

Step 2: Solve for x

  1. Subtract 14 on both sides:                    -25x > 6
  2. Divide -25 on both sides:                     x < -6/25

Here we see that any number x less than -6/25 would work as a solution to the inequality.
