Select the correct answer. A line t runs downward to the right through two parallel horizontal lines a and b, forming 8 angles numbered from 1 to 8. In the diagram, transversal t cuts parallel lines a and b. Which equation is necessarily true? A. m∠1 = m∠7 B. m∠3 = m∠6 C. m∠5 + m∠8 = 90° D. m∠6 + m∠7 = 180°
Since in the diagram, transversal t cuts parallel lines a and b, an equation which is necessarily true include the following: B. m∠3 = m∠6.
What is the Alternate Interior Angles Theorem?In Mathematics, the Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.
Based on the diagram representing (showing) the two parallel horizontal lines a and b, we can reasonably infer and logically conclude that angle 3 (m∠3) and angle 6 (m∠6) forms a pair of alternate interior angles because line a is parallel to line b and transversal (t) cuts parallel lines a and b.
Similarly, angle 4 (m∠4) and angle 7 (m∠4) forms a pair of alternate interior angles because line a is parallel to line b.

If Jen babysits for 3 hours, she earns $12; and for 5 hours she earns $20.
Graph this linear relationship with x =#hours, and y = dollars earned.
How much does she earn per hour?
Answer:
To graph this linear relationship, we can plot two points on a coordinate plane: (3,12) and (5,20). These points represent the number of hours Jen babysits (x-coordinate) and the amount of money she earns (y-coordinate).
We can connect these two points with a line to form a linear equation that represents the relationship between the number of hours babysat and the money earned.
The slope of this line can be found using the formula: (change in y) / (change in x) = (20-12) / (5-3) = 8/2 = 4
Therefore, Jen earns $4 per hour by babysitting.
It is important to note that this is a linear relationship, and the earnings are proportional to the number of hours babysat. This means that for any number of hours babysat, the earnings can be found by multiplying that number by $4.
Step-by-step explanation:
Answer: For every hour she babysits, she earns $4. ✅
Step-by-step explanation:
To graph the linear relationship, we can start by plotting two points: (3,12) and (5,20).
This represents that for 3 hours of babysitting, Jen earns $12, and for 5 hours of babysitting, she earns $20.
We can then use these points to find the slope of the line, which is the rate at which her earnings change as the number of hours increases.
The slope can be found by using the formula: (change in y) / (change in x) = (20 - 12) / (5 - 3) = 8/2 = 4
This means that for every hour she babysits, she earns $4.
So, the equation of the line is : y = 4x + b
Where b is the y-intercept, which can be found by substituting one of the points into the equation.
For example, by substituting (3,12) in the equation:
12 = 4(3) + b
b = 0
So, she earns per hour $4. ✅

What is the solution set of this compound inequality?
1≤|x+3|≤4
The solution of the compound inequality is -2 ≤ x ≤ 1 and -4 ≥ x ≥ -7.
What is compound inequality?An inequality that combines two other inequalities by using either "and" or "or" is referred to as a compound inequality. In certain cases, "and" won't be stated explicitly, but it is still understood. For instance, 1 x 3 simply means "x > 1 and x 3". However, a compound inequality using "or" is always explained in detail using "or." Compound inequalities may be divided into two categories: conjunction and disjunction.
The given compound inequality is:
1 ≤ | x + 3 | ≤ 4
As the equation contains a mod sign, we can write the inequality as follows:
1 ≤ x + 3 ≤ 4, and
1 ≤ - x - 3 ≤ 4
Simplify the first equation:
1 ≤ x + 3 ≤ 4
Subtract 3 from both the sides of the equation:
1 - 3 ≤ x + 3 - 3 ≤ 4 -3
-2 ≤ x ≤ 1
Simplify the second equation:
1 ≤ - x - 3 ≤ 4
Add 3 on both sides of the equation:
1 + 3 ≤ - x - 3 + 3≤ 4 + 3
4 ≤ -x ≤ 7
Convert the negative term to positive:
-4 ≥ x ≥ -7
Hence, the solution of the compound inequality is -2 ≤ x ≤ 1 and -4 ≥ x ≥ -7.

A subspace is a subset of a vector space that is closed under addition and scalar multiplication.The dimension of a subspace is the number of vectors in a basis for the subspace.Two subspaces of R^n can have the same dimension if they have the same number of vectors in a basis, but the vectors themselves could be different.For example, the subspace of all multiples of the vector (1,0) and the subspace of all multiples of the vector (0,1) both have dimension 1, but they are different subspaces because they contain different sets of vectors.The subspace of all multiples of the vector (1,0) is the set of all vectors of the form (x,0) and the subspace of all multiples of the vector (0,1) is the set of all vectors of the form (0,y) and these two sets are different.Therefore, the statement "If s1 and s2 are subspaces of R^n of the same dimension, then s1 = s2" is not true in general.

The shape of the parallelogram with vertices P(−4,0), Q(0,4), R(4,0), and S(0,−4) is a square
How to solve for the shapeIn order to get the shape using the vertices that we have, we would have to find the length of the diagonals

The length of the diagonal PQ is given as:
PQ = [tex]\sqrt{(0-4)^2+(4-0)^2}[/tex]

Based on the sides of a triangle, a triangle is classified into 3 types, namely:
Scalene Triangle – All the sides are of different measures.
Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.
Equilateral Triangle – All the 3 sides of a triangle are of the same measure.
Based on the angles of a triangle, a triangle is classified into 3 types, namely:
Acute Angle Triangle – All the angles of a triangle is less than 90°.
Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.
Right Angle Triangle – One of the angles of a triangle is equal to 90°.
