Correct answer is A. Amal owes Bella  x 3(-2.5)

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

For both graphs to be parallel, the value of a = -1/2.

If two graphs are parallel, their equation expressed in slope-intercept form y = mx + b, will have the same value of m which is the slope of the graphs.

Given, 4 = 3x + 6y, rewrite both equations in slope-intercept form:

4 = 3x + 6y

-3x + 4 = 6y

-3x/6 + 4/6 = 6y/6

-1/2x + 2/3 = y

y = -1/2x + 2/3 [slope (m) = -1/2]

This means that for both graphs to be parallel, the value of a = -1/2.

The coordinate of point I is such that ΔI K L is a right-angle triangle that will be either (0,y) or (2a,y).

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

Given the ΔI K L right angle triangle.

The possible coordinate of the point I will be either  (0,y) if IJ is perpendicular to JK and IK is perpendicular to JK.

The slope is 23, from x>=1 , the domain is (1,∞) and the range is {f: A→B; f(x) = 23x}.

Given,

Cost for first day = $39

Cost for each additional day = $23

Let x denote the number if days

Y denote the total cost

(a) As the cost for the first day to rent a zoom $39, so its domain is from (x=0 to x=1)

i.e., (0,1] and Range is $39 --> for the first day

For each additional day, the cost increases by $ 23.

Therefore, slope is 23, from x>=1.

(b) For the first day = $39

Therefore, cost is fixed for the first day its domain is (0,1] and Range is $39

For each additional day, cost increases by $ 23

Therefore, slope after x=1 is 23

Domain = (1,∞)

Ranges = {f: A→B; f(x) = 23x}

Ranges will be set of positive integers of multiple of 23

i.e., {23,46,69…….}

(c) Set of equations to model the relationship.

[tex]\mathrm{y}=\mathrm{f}(\mathrm{x})=\left\{\begin{array}{c}\$ 39,0 \leq x \leq 1 \\39+23 x, x > 1\end{array}\right.[/tex].

Hence, the slope is 23, from x>=1 , the domain is (1,∞) and the range is {f: A→B; f(x) = 23x} can be used to model relationship between the price of renting a car and the number of days you rent it.

The Jon's age is 35 years.

We are given the product of ages of both the persons. Also, we are given Jon's age = j years and Laura's age = (j + 3) years. So, representing the given information in mathematical expression form -

j × (j + 3) = 1330

Performing multiplication on Left Hand Side of the equation to find the value of j

j² + 3j = 1330

Shifting 1330 to Left Hand Side of the equation to find the value of j

j² + 3j - 1330 = 0

Solving the mentioned quadratic equation by factorization -

j² + 38j - 35j - 1330 = 0

Further solving the quadratic equation -

j (j + 38) -35 (j + 38) = 0

(j + 38) (j - 35) = 0

j = 35, -38

Answer:GCF = 6

Step-by-step explanation=Notice we have these factorizations

12 = 6*2

18 = 6*3

Which shows that 6 is the greatest common factor (GCF)

So,

12+18 = 6*2+6*3 = 6*(2+3)

We use the distributive property which is a(b+c) = ab + ac

I'll leave the 2+3 part un-simplified so that you can see the two original pieces, and how the 6 can multiply with them both to get back to 12+18 again.

The radius of a circle with an area of π/4 square units is B. 0.5 units

Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of the three-dimensional object.

Now it is given that,

Area of circle =  π/4 square units

Since we know that,

Area of circle =  πr²

where r is the radius of circle.

⇒ r² =  Area of circle / π

Put the values we get,

⇒ r² = (π/4)/ π

⇒ r² = 1/4

Taking square root both the side we get,

⇒ r = 1/2 units

or,  r = 0.5 units

Thus, the radius of a circle with an area of π/4 square units is B. 0.5 units

A decimal number is a very common number that we use frequently.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Symmetric property states that if a = b  then b = c

For example 2 = 1 + 1 ⇒ 1 + 1 = 2

Transitive property states that if a = b , b = c then a = c

For example 4 = 2 + 2 and 2 + 2 = 5 - 1 then 4 = 5 - 1

Substitution property states that if a = b then we can put b instant of an in any equation.

For example 4 = 2 + 2 then 8×4 = 8(2+2)

Hence "The example of real word on Symmetric, Transitive, and Substitution properties are {2 = 1 + 1 ⇒ 1 + 1 = 2} , {4 = 2 + 2 and 2 + 2 = 5 - 1 then 4 = 5 - 1} , { if 4 = 2 + 2 then 8×4 = 8(2+2) } respectively".

The missing second term of the given arithmetic sequence is: 2.5.

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

given: -3, __, 8 is an arithmetic sequence, where a₁ = -3 and a₃ = 8

Now, as [tex]a_n=a_1+(n-1)d[/tex], for the nth term of an arithmetic sequence,

For n = 3, a₃ = -3 + (3 - 1)d

=> 8 = -3 + 2d

=> 11/2 = d

=> d = 5.5

Hence, a₂ will be given as n = 2, in the above formula

=> a₂ = -3 + (2 - 1) (5.5)

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Two right triangles are supposed to be consistent on the off chance that they are of a similar shape and size. All in all, two right triangles are supposed to be consistent in the event that the proportion of the length of their comparing sides and their relating points is equivalent.

The probability that all three cards will be red is [tex]\frac{2}{17}[/tex]

In a deck of cards, the total number of cards is 52.

The total number of red cards in a deck is 26 i.e., half the total number of cards.

Selection of 3 cards from 52 cards is done according to 52C3.

Selection of 3 cards from 26 red cards is done according to 26C3.

∴ Probability = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
