What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]f(x) = x^2 + 3[/tex]
when [tex]x=-4[/tex] so,
[tex]f(-4)=(-4)^2+3\\\\f(-4)=16+3\\\\f(-4)=19[/tex]
Hence, the value of the equation [tex]f(x) = x^2 + 3[/tex] is [tex]19.[/tex]

What is 1/3 plus 3/4
Answer:
1
Step-by-step explanation:
At Wegmans a 12 pack of paper towels costs $15.72. At Tops a 10 pack of paper towels cost $13.35. Which store has the better buy? What is the difference in unit prices?
Answer:
Wegman's, roughly 3 cents
Step-by-step explanation:
Divide the price by the number of paper towels in the pack to get the unit price.
$15.72/12= $1.31
$13.35/10= $1.335, round since it's money, $1.34
$1.34-$1.31= $0.03 or 3 cents
Wegmans has the better buy, as their unit price is lower.
The difference in unit prices between the two stores is $0.03 per paper towel.
To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.
The unit price is the cost per paper towel.
For Wegmans:
Cost of 12 pack of paper towels = $15.72
Number of paper towels in the pack = 12
Unit price at Wegmans = Total cost / Number of paper towels
Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel
For Tops:
Cost of 10 pack of paper towels = $13.35
Number of paper towels in the pack = 10
Unit price at Tops = Total cost / Number of paper towels
Unit price at Tops = $13.35 / 10 = $1.34 per paper towel
Now, we compare the unit prices:
At Wegmans, the unit price is $1.31 per paper towel.
At Tops, the unit price is $1.34 per paper towel.
The store with the lower unit price has the better buy.
In this case, Wegmans has the better buy, as their unit price is lower.
To find the difference in unit prices:
Difference in unit prices = Unit price at Tops - Unit price at Wegmans
Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel
So, the difference in unit prices between the two stores is $0.03 per paper towel.

Find the measure of C for the circle :
Answer:
x = 72
Step-by-step explanation:
∠DBC is an included angle and arc DB is its corresponding arc
Relationship between an included angle and its corresponding arc: an included angle is equal to one half of its corresponding arc
so
∠DBC = [tex]\frac{1}{2}[/tex] arc DB
we are given that arc DB = 144
so we exchange arc db with 144
∠DBC = [tex]\frac{1}{2} 144[/tex]
[tex]\frac{1}{2} 144=72[/tex]
so we can conclude that ∠DBC (x) = 72

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
$135
Step-by-step explanation:
Step 1
Conversion
Base = 2 yards
1 yard = 3 feet
2 yards = x
Cross Multiply
x = 2 × 3 feet = 6 feet
Height = 5 yards
1 yard = 3 feet
5 yards = x
Cross Multiply
x = 5 × 3 feet = 15 feet
Step 2
Find the area of the triangle
Area of a triangle = 1/2 × base × height
Base = 6 feet
Height = 15 feet
Area = 1/2 × 6 × 15
= 45 square feet
Step 3
Find the cost of the carpet
1 Square foot = $3
45 square feet = x
Cross Multiply
x = 45 × $3
x = $135
Therefore, the amount you will pay to cover a triangular section of the floor is $135
When finding the area of a quadrilateral, what operation would I use and why?
Use the formula width x height = area. If the width is 4 inches and the height is 2 inches, the area equals 8 inches squared.

Determine the measure of the area of
a sector of 90° in a circle whose
diameter measures 13 centimeters
Answer:
Area of sector = 132.78 cm² (Approx.)
Step-by-step explanation:
Given:
Angle created by sector = 90°
Diameter of circle = 13 centimeters
Find:
Area of sector
Computation:
Radius of sector = Diameter of circle / 2
Radius of sector = 13 / 2
Radius of sector = 6.5 centimeters
Area of sector = [θ/360]πr²
Area of sector = [90/360][22/7][13]²
Area of sector = [1/4][22/7][169]
Area of sector = [0.25][3.1428][169]
Area of sector = 132.78 cm² (Approx.)
