Step-by-step explanation
Well you gave no answer choices so here are the steps and maybe you can just find out which one isn't here :)
18=2(4+x) first multiply 2 into 4+x
18=8+2x then subtract 8 from the other side
10=2x divide both sides by 2

The coordinates of the vertices of the translated triangle are A'(x, y) = (1, 8), B'(x, y) = (2, 6) and C'(x, y) = (- 1, 6).
How to translate a triangle by transformation rules
Graphically speaking, triangles can be generated by knowing its three vertices. In this question we must apply a kind of rigid transformation known as translation, whose formula is:
P'(x, y) = P(x, y) + T(x, y) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vectorIf we know that A(x, y) = (3, 4), B(x, y) = (4, 2), C(x, y) = (1, 2) and T(x, y) = (-2, 4), then the new coordinates are:
A'(x, y) = (3, 4) + (- 2, 4)
A'(x, y) = (1, 8)
B'(x, y) = (4, 2) + (- 2, 4)
B'(x, y) = (2, 6)
C'(x, y) = (1, 2) + (- 2, 4)
C'(x, y) = (- 1, 6)
Remark
The statement presents typing mistakes, correct form is:
Translate the triangle with the vector <- 2, 4>, then enter the new coordinates:
Original coordinates - A(x, y) = (3, 4), B(x, y) = (4, 2), C(x, y) = (1, 2).

Let a, b, and c be positive integers that form a geometric sequence. Given that a has 3 factors and c has 9 factors, how many factors can b have, at most?
Answer choices: 14, 9, 6, 8, 10.
DO NOT ATTEMPT IF YOUR NOT 98% SURE
Answer:
9
Step-by-step explanation:
it’s clear that a ,b and c are in geometric progression.
Then we have :
a
b = q×a
c = q²×a
also , b² = a×c
………………………
NOTE : b² and b have the same factors
also ,since b² = a×c then b and a×c
have the same number of factors.
_______________________________
Since c = q²×a then any factor of a is also a factor of c
Which means the number of factors of a×c
is equal to the number of factors of c.
Therefore b at most has the same number of factors as c.
Conclusion:
at most b has 9 factors.
……………………
As a side note :
You can take as example the numbers 3 , 30 , 300.
3 ——-> 1 factor
30 = 3×5×2 ——-> 3 factors
300 = 3 × 5² × 2² ——-> 3 factors

Marjorie and Blaine make chairs together. Marjorie builds the seat and Blaine independently sews the cushions to rest on top of them. It takes Marjorie 1 1/2hours to build the seat and Blaine 40 minutes to sew the cushion. How long would it take for them to make 10 chairs?
Making 10 chairs would take Marjorie and Blaine 21 hours and 40 minutes.
How long does it take to make 10 chairs?The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively. This time is known as their speed.
The resulting figures are summed to get the total time.
Data and Calculations:The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)
The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.
Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).
Thus, making 10 chairs would take Marjorie and Blaine 21 hours and 40 minutes.

| 2x^2 + 5x + 3 | > 0

Now, both [tex]|2x+3|\ge0[/tex] and [tex]|x+1|\ge0[/tex] (since the absolute value of any number cannot be negative), so we just need to worry about when the left side is exactly zero. This happens for

I’m a football game the home team scored 2 times as many points as the visiting team, if the game ended with a total of 21 points. How many points did the visiting team score?
math!! please please helppp!!!
What is the slope of the line below?
(i attached an image)
a) (0,4)
b) -1/3
c) (-1.5,0)
d) 3
e) 4
f) (0,4)
g) -3
h) 1/3
Answer:
D
Step-by-step explanation:
you can use the slope intercept form: y = mx + b.
y = y cooordinate
m = slope
x = x coordinate
b = y intercept
the y intercept is 4.
the point (1, 7) is what we're going to use.
so the new equation is
7 = m + 4 (it would be 1m, but i rewrote it to be mathmatically correct)
subtract 4 from both sides, you should have 3 = m.
the slope is 3
The point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).
What are the coordinates of P'?
P’(1, 2)
P'(1, 1)
P'(1, –3)
P'(4, 4)
The resulting point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)
How to determined a resulting point by translation
In this question we need to determine the new location of a point by using a translation formula. Translations are rigid transformations in which a point is translated on a Cartesian plane. We have the following formula:
P'(x, y) = P(x, y) + (- 5, - 2) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointIf we know that P(x, y) = (6, - 1), then the resulting point is:
P'(x, y) = (6, - 1) + (- 5, - 2)
P'(x, y) = (1, - 3)
The resulting point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)

This graph shows the solution to which inequality?
The graph shows the solution to inequality is; y > ¹/₃x - 2
How to interpret Inequality Graphs?From the given graph, we see that the line joining the two dotted coordinates is a dashed line and as such the inequality will be less than or greater than.
Now, If a line passing through two points, then the equation of line is;
y - y1 = [(y2 - y1)/(x2 - x1)](x - x1)
Using the two given coordinates, we have;
y - (-3) = [(-1 - (-3))/(3 - (-3))](x - (-3))
y + 3 = (2/6)(x + 3)
y = ¹/₃x - 2
Since the related line is dashed and the shaded region is above the line, therefore the sign of inequality is >.
The graph shows the solution to inequality is;
y > ¹/₃x - 2
