Please help Which of the following inequalities is graphed on the coordinate plane?
Answer:
The inequality which represents the graph is y ≤ -2x + 1 ⇒ A
Step-by-step explanation:
To solve the question you must know some facts about inequalities
If the sign of inequality is ≥ or ≤, then it represents graphically by a solid lineIf the sign of inequality is > or <, then it represents graphically by a dashed lineIf the sign of inequality is > or ≥, then the area of the solutions should be over the lineIf the sign of inequality is < or ≤, then the area of the solutions should be below the lineLet us study the graph and find the correct answer
∵ The line represented the inequality is solid
∴ The sign of inequality is ≥ or ≤
→ That means the answer is A or B
∵ The shaded area is the area of the solutions of the inequality
∵ The shaded area is below the line
∴ The sign of inequality must be ≤
→ That means the correct answer is A
∴ The inequality which represents the graph is y ≤ -2x + 1

Write an equation of a line perpendicular to line CD in slope-intercept form that passes through the point (−1, 6).
Line CD is shown. C is at 1, 1. D is at 3, 5.
y = −0.5x − 5.5
y = −0.5x + 5.5
y = 2x + 13
y = 2x − 13
Answer:
its b
Step-by-step explanation:
i took the test
y = - 0.5x + 5.5 is the equation of a line perpendicular to line CD in slope-intercept form that passes through the point (−1, 6).
What is the slope-intercept form of a straight line?The slope-intercept form of a straight line is y = mx + c.
Here, x and y are coordinates, m is the slope and c is the y-intercept of the line.
Given, two points are C(1, 1) and (3, 5).
Therefore, equation of the line CD is:
[tex]\frac{x - x_{1} }{y-y_{1} }[/tex] = [tex]\frac{x_{1}-x_{2}}{y_{1}-y_{2}}[/tex]
⇒ [tex]\frac{x - 1}{y-1}[/tex] = [tex]\frac{1-3}{1-5}}[/tex]
⇒ [tex]\frac{x - 1}{y-1}[/tex] = [tex]\frac{-2}{-4}}[/tex]
⇒2(x - 1) = (y - 1)
⇒ y = 2x - 1
Let, line AB is perpendicular to the line CD and passes through the point (-1, 6).
Therefore, slope of the line CD is = 2.
We know, slope of CD × slope of AB = -1
Therefore, slope of AB = -1 / slope of CD = [tex]-\frac{1}{2}[/tex].
Now, line AB has a slope of [tex]-\frac{1}{2}[/tex] and passes through the point (-1, 6).
Therefore, equation of the line AB is:
(y - y₁) = m(x - x₁)
⇒ [y - (6)] = [tex]-\frac{1}{2}[/tex][x - (- 1)]
⇒ 2(y - 6) = (-x - 1)
⇒ 2y - 12 + x + 1 = 0
⇒ x + 2y = 11
⇒ y = - 0.5x + 5.5

A student has a class with four tests, each worth 100 points, and has earned these
scores on the first three tests: 75, 74, 71. What is her average now? What score must
she earn on the fourth test to get a B (80) in the class?
The student's average is 73.33.
The score on the fourth test to have a B is 100.
What is the average?The average can be determined by adding the scores and dividing it by the total scores.
Average on the first three scores : (75 + 71 + 74) / 3
220 / 3 = 73.33
Score on the fourth test to get an 80: 80 = (220 + x) / 4
80 x 4 = 220 + x
320 = 220 + x
x = 320 - 220

Remember that whole numbers that are next to each other, for example, 2 and 3, or 43, 44, and 45 are called consecutive numbers.
If n is the smallest of three consecutive integers, write an expression for the largest number.
Answer:
n +2
Step-by-step explanation:
If three numbers are consecutive, the 2nd number would be one more than the 1st number, and the 3rd number would be one more than the 2nd number.
Since the smallest number is n,
2nd consecutive number= n +1
3rd consecutive number
= n +1 +1
= n +2
Thus, the expression for the largest number is n +2.
Let's check!
If the smallest of the three consecutive number is 1, the 3rd consecutive number would be 3.
3rd consecutive number
= n +2
= 1 +2
= 3 (✓)

There are infinitely many solutions.

To prove these equation are the same
multiply every quantity by 2 using the multiplication property of equality.
[ -6x + 8y = 12 ] = 2 [ -3x + 4y = 6 ]
2(-3x) + 2(4y) = 2(6) = 2(-3x) + 2(-4y) - 2(6) = -6x + 8y = 12 = -6x + 8y - 12
2(-3x) + 2(4y) - 2(6) = -6x + 8y - 12
-6x + 8y - 12 = -6x + 8y - 12

Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5?
y-3=(x+2)
y-2 = (2x - 3)
y+2=- (– 3)
y + 3 = 4(x + 2)
Answer:
y + 2 = -4/5 (x - 3)
Step-by-step explanation:
y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.
unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?

Answer:
X y

Putting the value of x in equation u will get the value of y
The required table of values given that y = 5x + 20 will be given as
x y
2 30
3 35
4 40
Given the linear equation y =5x + 20
In order to fill the table, we will have to calculate the y-values for the corresponding x values given.
If x = 2
y = 5(2) + 20
y = 10 + 20
y = 30
If x = 3
y = 5(3) + 20
y = 15 + 20
y = 35
If x = 4
y = 5(4) + 20
y = 20 + 20
y = 40
Hence the required table of values will be given as

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions. PLS HELP ILL GIVE BRAINLIEST
Answer:
x is eighteen
y is fifty four
Answer:
x= 18 degrees and y=54 degrees
Step-by-step explanation:
Look at the top of the line AB. You can see that
3x+y+72=180
Now, look at the left side of the line CD. You can see that
y+90+2x=180
Hence, you have 2 equations in 2 unknows, which are possible to solve.
In resume, the 2 equations are:
3x+y+72=180
2x+y+90=180
By substracting the second equation to the first one, it yields
x-18=0
which implies x=18.
Now, we can susbstitute this value on the fist equation:
3(18)+y+72=180
54+y+72=180
y+126=180
y=180-126
y=54
We can corroborate these result in the second equation:
2(18)+54+90=
36+54+90=
90+90=
180.

The table below represents a linear function f(x) and the equation represents a function g(x): (See pic)
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer:
Step-by-step explanation:
A.
slope of f(x) remember that m=rise /run and see how you get from point (0,0) to (1,3) for example
m= rise 3/ run 1= 3
slope of g(x) you find by comparing it to y=mx+b wher m is slope and b is intercept so g(x) slope is m = 7
Slope of f(x) is 3 and slope of g(x) is 7 so g(x) go upward faster.
B.
again compare g(x) =7x+2 with y=mx+b where b is the y-intercept
g(x) has y-intercept at (0,2)
we can see from the table that at x=0 the y-intecept is 0
f(x) has y-intercept at (0, 0)
g(x) has a greater y-intercept point
Two sides and the non-included right angle of one right triangle are congruent to the corresponding parts of another
right triangle. Which congruence theorem can be used to prove that the triangles are congruent?
O AAS
O SSS
O SAS
OHL
Answer:
hypotenuse leg theorem or OHL
Step-by-step explanation:
Since the congruent angle is a right angle and it is not included, the two congruent sides of the triangles must include their hypotenuses and one of their legs.
The triangles would be congruent by the hypotenuse leg theorem, which states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, the triangles are congruent.
The congruence theorem that can be used to prove both triangles are congruent is: AAS
What is congruence theorem?As per this theorem the two triangles are congruent if two angles and a side not between these two angles of one triangle are congruent to two corresponding angles and the corresponding side not between the angles of the other triangle.
What is AAS Congruency Theorem?This one denotes Angle - Angle - Side and it means that if 2 angles and the non-included side of a triangle are equal to corresponding 2 angles and the non-included side of another triangle, then they are both congruent.
When we have two triangles in which the two angles and a non-included side of one is congruent to the corresponding two angles and corresponding non-included side of the other, both triangles can be proven to be congruent by the AAS Congruence Theorem.
Since the two sides and the non-included side of one triangle is congruent to the corresponding two sides and the non-included side of the other, the congruence theorem that can be used to prove both triangles are congruent is: AAS
