What is the translation of the point to its image? A (−1, 4)→ A' (3, 3)
Answer:
We validate that the formula to determine the translation of the point to its image will be:
A (x, y) → A' (x+4, y-1)
Step-by-step explanation:
Given
A (−1, 4)→ A' (3, 3)
Here:
A(-1, 4) is the original pointA'(3, 3) is the image of AWe need to determine which translation operation brings the coordinates of the image A'(3, 3).
If we closely observe the coordinates of the image A' (3, 3), it is clear the image coordinates can be determined by adding 4 units to the x-coordinate and subtracting 1 unit to the y-coordinate.
Thue, the rule of the translation will be:
A(x, y) → A' (x+4, y-1)
Let us check whether this translation rule validates the image coordinates.
A (x, y) → A' (x+4, y-1)
Given that A(-1, 4), so
A (-1, 4) → A' (-1+4, 4-1) = A' (3, 3)
Therefore, we validate that the formula to determine the translation of the point to its image will be:
A (x, y) → A' (x+4, y-1)
which equation is represented by this graph?
A. y = 2/3x - 2
B. y = 2/3x + 3
C. y = 3/2x - 2
D. y = 3/2x + 3
3/2x-2
C. it should be this one
9514 1404 393
Answer:
A. y = 2/3x - 2
Step-by-step explanation:
The line intersects the y-axis at -2, so eliminates choices B and D, which have y-intercepts of +3.
The line has a rise of 2 grid squares for a run of 3 grid squares, so has a slope of ...
m = rise/run = 2/3 . . . . . eliminates choice C
The appropriate choice is the one with a slope of 2/3 and a y-intercept of -2:
A. y = 2/3x - 2

Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa. Con la cuarta parte del dinero compró una bolsa de palomitas y le sobraron 5 euros. ¿Con cuánto dinero salió de casa?
Answer:
Héctor salió de su casa con 12 euros.
Step-by-step explanation:
Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:
[tex] C = \frac{1}{3}x [/tex] (1)
Cuando compró una bolsa de palomitas con la cuarta parte:
[tex] P = \frac{1}{4}x [/tex] (2)
Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:
[tex] x - C - P = 5 [/tex]
[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]
[tex] x = 12 [/tex]
Por lo tanto, Héctor salió de su casa con 12 euros.

For what value of k will the points (3,5) and (9,k) represent a proportional relationship?
Answer:
k = 15
Step-by-step explanation:
For a proportional relationship to exist then for both points
k = [tex]\frac{y}{x}[/tex] ← k is the constant of proportion, that is
[tex]\frac{5}{3}[/tex] = [tex]\frac{k}{9}[/tex] ( cross- multiply )
3k = 45 ( divide both sides by 3 )
k = 15

Two hikers are 77 miles apart and walking toward each other. They meet in 10 hours. Find the rate of each hiker if one hiker walks 3.3 mph faster than the other.
The speed of the slow hiker is_____ mph, and the speed of the fast hiker is______ mph.
Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph
Explanation:
One hiker walks 3.3 mph faster than the other.
Suppose, the speed of the slower hiker is mph.
So, the speed of the faster hiker will be:
Both hikers are walking toward each other and meet in 10 hours.
We know that,
So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours
miles.
Given that, they were 77 miles apart in the beginning. So the equation will be

D) 7x + y = -61
Answer:
B)-7x+y=61

y + 5 =(7xX)(7x-8)
y + 5 =(7x)(-56)
y – 5 =(7x)(-56+-5)

What is an equation of the line that passes through the point ( − 6 , − 1 ) (−6,−1) and is perpendicular to the line 6 x − y = 7 6x−y=7?
Answer:
y = [tex]-\frac{1}{6}[/tex] x - 2
Step-by-step explanation:
Given coordinate:
( − 6 , − 1 )
Equation of the given line is 6x− y = 7
Unknown:
Equation of the line that passes through the point and is perpendicular = ?
Solution:
A perpendicular line will have a slope that is of negative inverse to the one given;
6x - y = 7
-y = -6x + 7
y = 6x - 7
According to y= mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
Therefore, the slope of the line = 6
Perpendicular to this = [tex]-\frac{1}{6}[/tex]
The new line will be;
Let find the intercept;
-1 = [tex]-\frac{1}{6}[/tex] x (-6) + c
-1 = 1 + c
c = -2
The new line is;
y = [tex]-\frac{1}{6}[/tex] x - 2

A line has the equation
y=x+3
Write down the coordinates of the point where the line intersects the v-axis.
Answer
(
Write down the coordinates of the point where the line intersects the x-axis.
Answer
Given:
The equation of line is
[tex]y=x+3[/tex]
To find:
The x-intercept and y-intercept.
Solution:
The equation of line is
[tex]y=x+3[/tex]
Putting x=0, we get
[tex]y=0+3[/tex]
[tex]y=3[/tex]
So, the y-intercept is (0,3).
Putting y=0 in the given equation, we get
[tex]0=x+3[/tex]
[tex]-3=x[/tex]
So, the y-intercept is (-3,0).
Therefore, the coordinates of the point where the line intersects the y-axis are (0,3). The coordinates of the point where the line intersects the x-axis are (-3,0).

Answer:y=9x-7
Step-by-step explanation:
Answer:
y = 9x - 7
Step-by-step explanation:
Slope-intercept form is y = mx + b
Y-intercept is where x = 0. In this instance, when x = 0, y = -7 (0, -7)
So at this point we know b = -7.
Then, take one of the values of x, such as 1, as well as the corresponding value of y and plug in. When x = 1, y = 2 (1, 2)
2 = m(1) - 7
Solve for m (slope)
2 = m - 7
Add 7 to both sides to get m alone.
9 = m
Now we know the slope, and the y-intercept, so we can fill in the equation for slope-intercept form for this linear function.
y = mx + b
y = (9)x + (-7)
y = 9x - 7
− 7 / 8 + ( − 1 / 2 )

PLEASE HELP!! Determine whether the triangles are similar. If similar state how (AA~,SSS~, or SAS~), and write a similarity statement
Answer:
Yes they are similar because of SAS similarity
Step-by-step explanation:
the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.
ΔTSR ~ ΔFEG by the SAS Similarity Theorem
What is the SAS Similarity Theorem?SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.
In the image given, the two triangles have:
Two pairs of proportional sides - TS/FG = TR/FE = 3.A pair of congruent included angles - ∠T ≅ ∠F.This means they are similar by the SAS Similarity Theorem.
Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.

Answer:
1. 5, 11, 18, 26, 35, 45
Step-by-step explanation:
5, 11, 18, 26,
The difference between 5 and 11 is 6.
The difference between 11 and 18 is 7.
The difference between 18 and 26 is 8.
As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.
26 + 9 = 35
And the next difference would be 9 + 1 = 10.
35 + 10 = 45
