slope=2/7 y-intercept=-4
Answer:
y=2/7x-4
Step-by-step explanation:
Write in Slope intercept form
y=mx+b
m = slope
b = y intercept
x = x intercept
y = (0,-4)
So,
y = 2/7x+(-4) substitute
y = 2/7x-4

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.

Choose 1 answer:
A) x-7y=-61 B)-7x+y=-61 C) x+7y=-61
D) 7x + y = -61
Answer:
B)-7x+y=61
Step-by-step explanation:
y + 5 = 7(x– 8)
y + 5 =(7xX)(7x-8)
y + 5 =(7x)(-56)
y – 5 =(7x)(-56+-5)
y=7x-7x-61/

Given the function
f(x)=-1/2(1-x)^2,
find f(-5).
Answer:
f(x)= -1/2(1-x)^2
replacing x with -5 since -5 was given as the function
f(-5)=-1/2(1-5)^2
according to bodmas we solve what is in the bracket first
f(-5)=-1/2(-4)^2
f(-5)=-1/2(16)
-1/2*16/1
-16/2=-8

do –2(3x – 1) = –6x – 1 have one solution
Answer:
No solutions
Step-by-step explanation:
–2(3x – 1) = –6x – 1
First distribute the left side
-6x + 2 = -6x - 1
Add 1 to both sides
-6x + 3 = -6x
Add 6x to both sides
3 = 0
This equation is not true because 3 does NOT equal 0. Therefor, this equation has no solutions.
Answer:

Step-by-step explanation:
There are no values of x that make the equation true.
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:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180

Tuition for one year at a state university is about $13,000. Devon would like to attend this university and will save money each month for the next 4 years. His parents will give him $5,200 for his first year of tuition. Which plan shows the minimum amount of money Devon must save to have enough money to pay for his first year of tuition?
Answer:
$162.50 per month for the next 4 years
Step-by-step explanation:
Here are the options to this question :
Save $270.83 per month for the next 4 years
Save $162.50 per month for the next 4 years
Save $650.00 per month for the next 4 years
Save $108.33 per month for the next 4 years
If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :
$13,000 - $5,200 = $7,800
If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)
The minimum he should save per month = $7800 / 48 = $162.50

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

find the composition of transformations that map ABCD to EHGF
Answer:
(x - 1, y + 1 )
Step-by-step explanation:
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), thus
A'(5, 2 ) → E(4, 3 )
(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )
The translation rule is (x, y ) → (x - 1, y + 1 ).
What is Translation?In mathematics, translation is a transformation that moves every point of a figure or a graph the same distance and in the same direction. The object being translated retains its size and shape, but its position changes.
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), then
A'(5, 2 ) → E(4, 3 )
Thus, the translation rule is (x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )
