The expression (-1 ,-5) is not a solution to the inequality 4x + y < -3
How to determine if (-1 ,-5) is a solution to the inequality 4x + y < -3?The inequality is given as
4x + y < -3
The solution is given as
(-1, 5)
Substitiute (-1, 5) for (x, y) in the inequality expression 4x + y < -3
So, we have
4(-1) + 5 < -3
Open the bracket
-4 + 5 < -3
Evaluate the sum

Determine whether each logarithm is a common logarithm.
C. (log₁₀100)
Yes , the given logarithm is a common logarithmic.
A base 10 logarithm is a common logarithm.It is also known as decimal logarithm and is named after its base. It is also known as the Briggs logarithm, and the "standard logarithm", after Henry Briggs, the English mathematician who pioneered its use.Calculators usually say "logarithm", but mathematicians usually mean the natural logarithm (the logarithm with base e ≈ 2.71828), not the common logarithm when writing "logarithm". To reduce this ambiguity [tex]log_{10}x[/tex] should be written lg(x) and [tex]log_ex[/tex] must be ln(x).We have given an logarithm function which is [tex]log_{10}100[/tex] ..... (1)

A square has an area of 90 square inches. Which two consecutive integers does a side length of the square fall between?
The two consecutive integers in which the side length of the square fall between is 9 and 10
The formula for the area of a square is given as follows:
A = (s)²
where A = area of square
s = length of side of a square
According to the question we have been given that
the area of square = 90 inch²
Now putting the required values in the formula of area we get
(s)² = 90
Taking square root both sides we get
s = √90
As 90 is not a perfect square but it lies between two perfect squares which are 81 and 100.
As √81 = 9 and √100 = 10
Now, √81 ≤ √90 ≤ √100
⇒ 9 ≤ √90 ≤ 10
Hence two consecutive integers such that the side length of the square fall between is 9 and 10

Reasoning. If you multiply two decimals that are less than 1, can you predict wherer the product will be less than or greater than either of the factors? Explain.
The product is smaller than the factors of the product.
What can we predict about the product?Let's say that we have two real positive numbers A and B.
If we define 0 < A < 1
Then when we multiply A and B (a real positive number) we will have that:
A*B < B
So the value of B is decreased.
Now, if both numbers are in that range:
0 < A < 1
0 < B < 1
We will have that:
A*B < B
A*B < A
So the product is smaller than A and smaller than B, which are the factors of the product.
So the product is less than both of the factors.

a. BC
b. EB

In the cuboid, the line segment parallel to AD is BC as they both lie on same plane and are directed in same direction.
What are parallel lines?Two lines are said to be parallel if they lie on the same plane and are directed towards the same direction.
Given in the question is a labelled cuboid.
From the definition of parallel lines, they should lie on the same plane. Therefore, we will eliminate EB and EH because they don't lie in the plane of AB. CD lies in the plane of AB, but is directed perpendicular to AB. BC is in the same plane in which AB lies and is also directed in the direction of AB.

Interest Suppose you deposit $ 2000 in a savings account that pays interest at an annual rate of 4 % . If no money is added or withdrawn from the account, answer the following questions.
a. How much will be in the account after 3 years?
There will be $ 2249.728 in the account after 3 years .
Simple Interest : Each year interest is calculated on the principal amount ( the amount that was deposited initially ) .
Simple Interest = ( P * R * T ) / 100
P ( principal amount ) = 2000
R ( Rate of Interest ) = 4
T ( No . of years for which amount is deposited ) = 3
Substituting values
Simple Interest = ( 2000 * 4 * 1 ) / 100
= 80
Amount in account after 1 yr = 2000 + 80
= $ 2080
In second year amount will be = 2080 + [ ( 2080 * 4 * 1 ) / 100 ]
= 2080 + 83.2
= $ 2163.2
After three yrs . amount in account = 2163.2 + [ ( 2163.2 * 4 * 1 ) / 100 ]
= 2163.2 + 86.528
= $ 2249.728
Hence , there will be $ 2249.728 in the account after 3 yrs .

When making lasagna, Mr. Singleton uses 1 pound of sausage for every 3/4 of a pound of mozzarella cheese. For a dinner party, Mr. Singleton wants to make an extra lasagna with 1 pound of mozzarella cheese. How much sausage will he need?
Using ratio we can calculate that Mr. Singleton used approximately 1.33 pounds of sausage .
A ratio demonstrates how frequently one number is found within another. For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
A ratio can therefore be thought of as an ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or as the value represented by this fraction. Ratios of counts that are expressed in terms of (non-zero) natural numbers are rational numbers and occasionally natural numbers as well. The ratio of two numbers is a dimensionless number when they are measured using the same unit, which happens frequently. A rate is the product of two quantities that are divided by their respective units of measurement.He uses 1 pound sausage for every 3/4 pound of cheese.
Ratio of sausage to cheese = 1 : 0.75 = 4 : 3 .
Now he uses 1 pound of cheese therefore let he uses x pounds of sausage.
Now using ratio:
x : 1 = 4 : 3
or , x / 1 = 4 / 3
or, x = 1.333..
or, x ≈ 1.33 pounds
Hence he uses 1.33 about pounds of sausage

The fourth coordinate for the given parallelogram are going to be (5, 7).
According to the statement
We have to find that the coordinate of the parallelogram.
So, For this purpose, we know that the
A parallelogram is a quadrilateral with opposite sides parallel
From the given information:
The coordinates of three of the vertices of parallelogram ABCD are A(2, 0), B(4, 3), C(3, 1).
Then
Now,
The slope of AB = Slope of CD
(y - 5)/(x - 11) = (1 - 3)/(8 - 2)
6(y - 5) = -2(x - 11)
⇒ 6y + 2x = 52 are going to be the primary equation.
Now,
The slope of BC = Slope of AD
[(y - 3)/(x - 2)] = [(5 - 1)/(11 - 8)]
[(y - 3)/(x - 2)] = 4/3
3(y - 3) = 4(x - 2)
⇒ 3y - 4x = 1 are the second equation.
Now, By substitution
x = 5 and y = 7
