Answer:
a. +3
b. -12a
Step-by-step explanation:
Here, we want to know the steps that are involved in those unoccupied segments
let’s start with the output
6a + 18
So what turned a to 6a + 18
Let’s call that output x
Let’s reverse the last step that multiplied that term and a
Thus (6a + 18)/6 = a + 3
Thus the x-term we are looking for is + 3 before the multiplication by 6
Now for the second part;
a * 4 -3 = -12a
Solve the inequality
Answer:
x < 4
Step-by-step explanation:
3x - 3 < 9
3x < 12
x < 4
Answer: x < 4
Step-by-step explanation:
3x < 9 + 3
you’re going to add the two (9+3= 12) numbers.
3x < 12
Then divide both sides of the inequality by 3.
3x < 12 = x < 4.

F
Answer:
yes, if AB ≅ DE
Step-by-step explanation:
Triangles are said to be congruent if they have the same sides and the same angles.
The following measures are used to determine if triangles are congruent:
1) Angle-side-angle: If two angles and a side of a triangle is equal to two angles and corresponding side of another triangle, then they are congruent.
2) Side-side-side: If all three sides of a triangle is equal to three sides of another triangle, then the two triangles are congruent.
3) Side angle side: If two sides and an included angle of a triangle is equal to the two sides and corresponding angle of another triangle, then they are congruent.
4) Hypotenuse - leg: If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.
From the triangles DEF and ABC, already, they already have one equal triangle that is ∠F = ∠B and an equal side i.e DF = AC.
To satisfy congruence, two sides and an angle have to be equal, therefore if AB = DE then the two triangles would be congruent
Answer:
D). no, because the hypotenuses must have different lengths
Step-by-step explanation:
I just did the assignment on Edge and it's 100% correct.

How many solutions does the system have? Y=-2x-4 y=3x+3
Answer:
1
Step-by-step explanation:
Since they are not parallel nor the same line, they have 1 intersecting point, which is the solution.
If they were parallel, they would have no solution.
If they were the same line, they would have infinite solutions.
boxes A and B contain some counters
box A contains more counters than box B
box A: 4k counters
Box B: k+9 counters
what is the smallest possible value of K
Step-by-step explanation:
If we take 4 as k then
4k = 4(4) = 16 boxes
k + 9 = 4 + 9 = 13 boxes
Answer:
4
Step-by-step explanation:
Box A = 4k
Box B = k+9
Box A > Box B
=> 4k > k+9
Subtracting k to both sides
=> 4k-k > 9
=> 3k > 9
Dividing both sides by 3
=> k > 3
So, The smallest possible value of k is 4

Answer:
so the coordinates of C are (12,29)
Step-by-step explanation:
as we know that CD is a line segment and M is its mid-point in order to find the coordinates of C we will use mid-point formula
[tex]M(x,y)=(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
putting the values of known coordinates
[tex](15,-6.5)=(\frac{x1+18}{2},\frac{y1+(-16)}{2})[/tex]
comparing the coordinates separately
[tex]15=\frac{x1+18}{2}[/tex] and [tex]-6.5=\frac{y1-16}{2}[/tex]
15×2=x1+18 and -6.5×2=y1-16
30=x1+18 and 13=y1-16
30-18=x1 and 13+16=y1
12=x1 and 29=y1
so the coordinates of C are (12,29)
in order to check the values put it back in the mid-point formula to find the coordinates of M

An x-method chart shows the product a c at the top of x and b at the bottom of x. Below the chart is the expression a x squared + b x + c Consider the trinomial x2 + 10x + 16. Which pair of numbers has a product of ac and a sum of b? What is the factored form of the trinomial?
Answer:
The pair of numbers that has a product of ac and a sum of b = (+2, +8)
The factored form of the trinomial = (x+2) (x+8)
Step-by-step explanation:
ax² + bx + c = 0
This is in the form of a trinomial algebraic expression
Given trinomial: = ax² + 10x + 16
Where a = 1, b= 10, c= 16
To find the pair of numbers that has a product of ac and a sum of b, we would solve the equation.
Using factorisation method:
ac = a×c = 1×16 = 16
Let's find the factors of 16 whose sum gives +10 and product gives +16
Factors of 16 = 1, 2, 8, 16
+2 + +8 = +10
+2 × +8 = +16
The factors are +2 and +8
The pair of numbers that has a product of ac and a sum of b = (+2, +8)
x² + 10x + 16 = x + 2x + 8x + 16
x² + 10x + 16 = x(x+2) + 8(x+2)
= (x+2) (x+8)
The factored form of the trinomial = (x+2) (x+8)
Answer:
(x+2) (x+8)
Step-by-step explanation:
what number must you add to complete the square? x^2-7
Answer:
12.25
Step-by-step explanation:
To find the c value in the equation, we need to divide b by two and then square it.
b= -7 and -7/2 is 3.5
Then we square 3.5 and we get 12.25
Answer:
(x+0)^2-7
Step-by-step explanation:
x^2-7 to complete the square use the formula (b/2)^2 in order to create a new term.
ax^2+bx+c in this case b=0
(x+0)^2-7

The graph for the equation y = negative 2 x + 1 is shown below. On a coordinate plane, a line with negative slope goes through (0, 1) and (1, negative 1). If another equation is graphed so that the system has no solution, which equation could that be?
Options:
y = negative 2 (x minus one-half)
y = negative one-half (4 x + 2)
y = negative x + 1
y = negative one-half x + 2
Answer:
y = negative 2 (x minus one-half)
Step-by-step explanation:
The equation of a line is given as:
y = mx + c, where m is the slope and c is the intercept on the y axis.
The equation of a line going through (0, 1) and (1, - 1) is calculated using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\ y-1=\frac{-1-1}{1-0}(x-0)\\ y-1=-2x\\y=-2x+1[/tex]
The solution of two lines is at their point of intersection. The equation of the line that would not have any solution with y = -2x + 1 would be a line that is parallel to y = -2x + 1. Since the two lines would be parallel to each other, their would be no intersection and therefore no solution.
Two lines are said to be parallel to each other if they have the same slope. The slope of y = -2x + 1 is gotten by comparing with y = mx + c, therefore the slope m = -2. From the options the only line with a slope m = -2 is y = -2(x -1/2). Therefore y = -2(x -1/2) is parallel to y = -2x + 1 and would have no solution

Kira drew traingle pqr and stu so that angle p is congruent to angle s, angle q is congruent to angle t, pr equals 12, and su equals 3. Are triangles pqr and stu similar? If so identify the similarity postulate or theorem that applies
Answer:
The similarity postulate theorem is;
Similar - AA
Step-by-step explanation:
We are told that angle p is congruent to angle s, angle q is congruent to angle t.
Thus it is an AA similarity theorem because AA similarity theorem states that: If two angles in one triangle are congruent/respectively equal to two angles of another triangle, then the 2 triangles are similar.
For example, if we assume ΔABC and ΔDEF to be two triangles such that ∠A = ∠D and ∠B = ∠E. Then the two triangles are equiangular and thus they are similar by AA.
Answer: similar AA is correct

find the number of pencils (x) and pens (/) he bought?
Ox+ 1.5y = 7
X + y = 6
O 1.5x + y = 7
x=6y
Ox + 2y = 7
6x = 1.5y
O 2x + y = 7
6x = 1.5y
Answer:
The first equation is correct
Step-by-step explanation:
Answer: A
Step-by-step explanation:
Because he bought 6 items, x + y = 6. Because a pencil costs 1 dollar and a pen costs 1.5 dollars, and Stefan spent 7 dollars, 1x+1.5y=7.

Explain how you setup your excel worksheet. Make sure to address any formula used by showing an example but avoid using cell references (B5, A3, G12, etc.) What final course percentage (to 1 decimal) did you calculate? What letter grade in the course did this student earn?
Answer:
Step-by-step explanation:
to set a spreadsheet on excel, you start with the category labels on the top row, then you go down in columns. Then you enter the scores that you want for each category . after you are done with entering the scores, you found the average percent of each category by dividing the total amount of scores by the number of score in one cell . For Example, the total score was 1530 and there was 20 , you got 76.5%. you continue this for each category. Then multiplied it by the category weights. Finishing it off, I added each categories’ answers up and got my final grade of 76.5%. The letter grade this student got was a C.(google spread sheet)
Choose the inverse of y=x^2-10
Answer:
x = 5 + sqrt(y+25), for x>=5
x = 5 - sqrt(y+25), for x<=5
Step-by-step explanation:
y = x^2 - 10x + 25 - 25
y = (x-5)^2 - 25
y+25 = (x-5)^2
x-5 = +/-sqrt(y+25)
And you get TWO inverses:
x = 5 + sqrt(y+25), for x>=5
x = 5 - sqrt(y+25), for x<=5

Choose the slope and y-intercept that
correspond with the graph.
Answer:
slope = 2 and y- intercept = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 2)
m = [tex]\frac{2+2}{2=0}[/tex] = [tex]\frac{4}{2}[/tex] = 2
The y- intercept is the value of the y- coordinate at the point where the line crosses the y- axis, that is
y- intercept = - 2
