Find the equation of the vertical line passing through the point (5, 5)
9514 1404 393
Answer:
x = 5
Step-by-step explanation:
The equation of a vertical line is of the form ...
x = constant
In order to make that line go through a point that has an x-coordinate of 5, the value of the constant must be 5.
x = 5
Describe an Constraint in math
Answer: mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.

Given that f(2)=9 we know that f(x) can be (insert part one of answer)
choices f(x)=2x+5 or f(x)=4x+5.
This means that f(3) is
choices 11 or 17(insert part 2 of answer)
Answer:
f(x) = 2x+5
f(3) = 2(3) +5 = 6+5 =11
There fore f(3) =11
The first function is correct
Step-by-step explanation:
Given f(2) =9 and given functions are f(x) = 2x+5 and f(x) =4x+5
The fsecond function is not satisfies f(2)=9 because
f(x) = 4x+5
f(2) = 4(2)+5 = 13≠9
f(x) = 2x+5
f(2) = 2(2)+5=9
therefore first function is satifies
f(x) = 2x+5
f(3) = 2(3) +5 = 6+5 =11
There fore f(3) =11
What is Sampson’s mistake?
A: Sampson should subtract 3 from both sides of the inequality.
B: Sampson should divide by -3 on both sides of the inequality.
C: Sampson did not change the direction of the inequality symbol after multiplying both sides of the inequality by a negative number.
D: Sampson’s father found no mistakes in his work and the answer is correct.
Answer:
C: Sampson did not change the direction of the inequality symbol after multiplying both sides of the inequality by a negative number.
-3 + 3 is zero but Sampson take it as (-3) which is wrong
Answer: Choice C
Sampson did not change the direction of the inequality symbol after multiplying both sides of the inequality by a negative number.
In short, the inequality sign must flip when we multiply both sides by a negative number.
After solving for x, the result should be x > -22.5

Determine the missing term to make these ratios equal: 10 : 65 = : 26
Answer:
10:65 = 4:26
Step-by-step explanation:
Set up a proportion: [tex]\frac{10}{65} = \frac{x}{26}[/tex] Cross multiply, then divide: 10 × 26 = 260, 260 ÷ 65 = 4So, the missing term is 4I hope this helps!

The tiger population in southern India can be predicted by the expression below. Where x is the number of years since 2000. What does the value of 3097 represent?
3097(1.02) x
Answer:
The Bengal tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to the Indian subcontinent.[3] It is threatened by poaching, loss, and fragmentation of habitat, and was estimated at comprising fewer than 2,500 wild individuals by 2011. None of the Tiger Conservation Landscapes within its range is considered large enough to support an effective population of more than 250 adult individuals.[1] India's tiger population was estimated at 1,706–1,909 individuals in 2010.[4] By 2018, the population had increased to an estimated 2,603–3,346 individuals.[5] Around 300–500 tigers are estimated in Bangladesh, 220–274 tigers in Nepal and 103 tigers in Bhutan.[1][6][7]Kingdom:

A car uses 9.8 gallons of gas to travel 245 miles. How many miles are traveled per gallons of gas used.
Answer:
The car travels 25 miles per gallon of gas used
Step-by-step explanation:
Unit Rate
It's given a car uses 9.8 gallons of gas to travel 245 miles.
We have to calculate how many miles the car travels per gallon. The unit rate gives us that result by dividing the number of miles by the gallons used:
unit rate = 245 miles / 9.8 gallons = 25
The car travels 25 miles per gallon of gas used

Step-by-step explanation:
Linda and Roy are solving the equation 4x+3x-7=(1+4x)+5x. Linda uses a first step that results in 4x+7-3x=(1+4x)+5x Roy uses a first step that results in 4x+3x-7=1+(4x+5x) which statement about the first steps Linda and Roy use is true
Answer:
Option C
Step-by-step explanation:
Linda used the first step that results in,
4x + 7 - 3x = (1 + 4x) + 5x
As Linda changed the sign of (3x) to (-3x), it doesn't matches the original equation.
So she is not correct.
Roy used the first step as,
4x + 3x - 7 = 1 + (4x + 5x)
He has used the associative property in the right hand side of the given equation.
Associative property → (a + b) + c → a + (b + c)
Therefore, he is correct.
Option C is the correct option.

Determine whether the triangles are congruent by, sss, sas, asa, aas, or hl
Answer:
NOT CONGRUENT
Step-by-step explanation:
Given:
AB ≅ CD
∠DCB ≅ ∠DAB
To prove:
ΔABD ≅ ΔDCB
Statements Reasons
1). AB ≅ CD 1). Given
2). ∠DCB ≅ ∠DAB 2). Given
3). DB ≅ DB 3). Reflexive property
4). ΔABD ≅ ΔDCB 4). SSA property of congruence.
But in the given options SSA property is not given.
So the answer is NOT CONGRUENT.

the slope of the line that passes through the point (-9, 3) and (3,21) is which of the following
1) 2/3
2) -2/3
3) 3/2
4) -3/2
Answer:
[tex]\displaystyle m=\frac{3}{2}[/tex]
Step-by-step explanation:
The slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (-9,3) and (3,21), thus:
[tex]\displaystyle m=\frac{21-3}{3+9}[/tex]
[tex]\displaystyle m=\frac{18}{12}[/tex]
Simplifying by 6:
[tex]\mathbf{\displaystyle m=\frac{3}{2}}[/tex]
