Answer:
7*p
Step-by-step explanation:
The product of two numbers is just the two numbers multiplied.
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.
Answer:
F(4) = 85
Step-by-step explanation:
F(x) = 18x + 13
F(4) = 18(4) + 13
F(4) = 72 + 13
F(4) = 85

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
∵ 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.
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
where
Given the points
Determining the slope between (-6.4, -2.6 )and (5.2,9)
Refine
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

Step-by-step explanation:
Step 1: Define
-25x + 14 > 20
Step 2: Solve for x
Here we see that any number x less than -6/25 would work as a solution to the inequality.
