Answer:
Step-by-step explanation:
Given the function :
f(x) = 7x - 8
Evaluate the given values of the independent variable and simplify.
a. f(7)
b. f(x + 5)
c. f(-x)
A.) f(7)
f(7) = 7(7) - 8
= 49 - 8
= 41
B.) f(x + 5)
7(x + 5) - 8
7x + 35 - 8
7x - 27
C.) f(-x)
7(-x) - 8
-7x - 8
Answer:
-5
Step-by-step explanation:
Linda needs to buy about 7 balls of wool to knit a baby’s blanket.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
1 yard = 36 inches
1 inch = 2.54 cm = 0.0254 m
Hence:
1800 yard = 1800 yard * 36 in per yard = 64800 in
64800 in = 64800 in * 0.0254 m per in = 1645.92 m
Since there are 245 metres of wool in each ball of wool. hence:
Number of wool balls = 1645.92 m / 245 m = 6.72
Linda needs to buy about 7 balls of wool to knit a baby’s blanket.

Answer:
(2, -11)
Step-by-step explanation:
(x + 3, y + 2) = (5, -9)
x + 3 = 5
y + 2 = -9
x = 2
y = -11
