You flip the y coordinate of point S from -4 to +4. The x coordinate stays the same.
=====================================================
Problem 5
Focus on the points W and X. Because the y coordinates are both 1, we subtract the x coordinates to get 4-1 = 3. The distance from W to X is 3 units. This is another way of saying segment WX is 3 units long. This applies to the preimage.
Then we're told the image has W'X' = 6 which is twice as long as WX = 3. Therefore, the scale factor is 2.
We can write it like this:
[tex]\text{scale factor} = \frac{\text{image length}}{\text{preimage length}} = \frac{W'X'}{WX} = \frac{6}{3} = 2[/tex]
This indicates that each side of W'X'Y'Z' is twice as long compared to each corresponding side of WXYZ.

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents
the width of the rectangle in inches, which equation can be used to find its value?
Answers
Answer:
Width = 4
Length = 10
Step-by-step explanation:
Width: x
Length: x+6
2x + 2(x+6) = 28
2x + 2x + 12 = 28
4x = 28-12
x = 16/4
x = 4

Which describes the graph of y = (x - 4)2 - 1?
-
A. Opens up with a vertex at (4,-1)
B. Opens down with a vertex at (4,-1)
C. Opens up with a vertex at (-4,-1)
D. Opens down with a vertex at (-4,-1)
Answers
C opens up with a vertex at (-4,-1)
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x - 4)² - 1 ← is in vertex form
with vertex = (h, k ) = (4, - 1 )
• If a > 0 then the graph opens up
• If a < 0 then the graph opens down
Here a = 1 > 0 then graph opens up
Thus option A

What is an equation of the line that passes through the points (-3, -1) and (6, 2)
Answers
Answer:
y = 1/3x
Step-by-step explanation:
Using the slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
Taking (-3,-1) as (x1,y1) and (6,2) as (x2,y2):
(2-(-1))/(6-(-3))
= (2+1)/(6+3)
= 3/9
= 1/3
Hence, the slope (m) is 1/3
Substituting the slope into 'y = mx+c':
y = 1/3x + c
Substituting any point, however, we will be substituting (-3,-1):
-1 = 1/3 * (-3) + c
-1 = -1 + c
c = -1 + 1
= 0
Hence,
y = 1/3x

two numbers that multiplied together give me 10 and the difference of the two numbers is -2?
Answers
Answer:
10/(1+√11), 1+√11 and 10/(1-√11) and 1-√11
Step-by-step explanation:
Let x be the first number and y the second number
two numbers that multiplied together give me 10
x*y = 10
and the difference of the two numbers is -2?
x-y = -2
we can write x in terms of y so we only have one variable y
x-y =-2 , add y to both sides
x-y+y = y -2, combine like terms
x= y-2
x*y = 10, substitute x=y-2
(y-2)y = 10, distribute in parenthesis
y² -2y-10 = 0, subtract 10 from both sides
We can use the quadratic formula to solve y² -2y-10 = 0
y = (-b±√b²-4ac)/2a, where a= 1, b= -2, c= -10
y = (2±√4+4*1*10)/2
y = (2±√44)/2
y= (2±2√11)/2
y= 1±√11
x*y = 10, divide both sides by y
x= 10/y
x= 10/(1±√11)
Check :
x*y = 10
[10/(1±√11)] * (1±√11) = 10
⇒[10/(1+√11)] * (1+√11) = 10✅
⇒[10/(1-√11)] * (1-√11) = 10✅
⇒[10/(1+√11)] * (1-√11) = 10❌
⇒[10/(1-√11)] * (1+√11) = 10❌
x-y = -2
⇒
[10/(1+√11) ] -(1+√11) =
[10 -(1+√11 )(1+√11 )]/ (1+√11 ) =
[10 - (1+11+2√11)]/ (1+√11) =
(10-12 -2√11) / (1+√11) =
(-2 -2√11) / (1+√11) =
-2(1+√11)/ (1+√11) =
-2 ✅
⇒
[10/(1-√11) ] -(1-√11) =
[10 -(1-√11 )(1-√11 )]/ (1-√11 ) =
[10 - (1+11-2√11)]/ (1-√11) =
(10-12 +2√11) / (1-√11) =
(-2 +2√11) / (1-√11) =
-2(1 -√11)/ (1-√11) =

QUESTION !$ I NEED HELP

The distance that you travel at a constant speed varies directly with the time spent traveling. It takes you 2 h to travel 100 mi. Write an equation for the relationship between time and distance. How far would you travel in 3.5 h?
Answers
100 miles is the distance we know traveled in 2 hours. Therefore we can make this equation:
100 = 2x
100 / 2 =x
50 = x
We travel 50 miles an hour.
Now we know the x, 3.5 so lets plug that in:
3.5x = y
3.5(50) = y
175 = y
Therefore we travelled 175 miles in 3.5 hours.
I hope this helps! :)
Answer:
The speed is distance / time and speed times time equals distance
Step-by-step explanation:
speed = 100/2=50 mi/hr
distance =f(t)=50t
f(3.5)=50×3.5=175miles

Answer:
46.8
Step-by-step explanation:
The missing angle in ∆PQR is 180° -76° -41° = 63°. Two angles are the same between the triangles, so we know they are similar. Side lengths of similar triangles are proportional.
Corresponding sides of the triangles are ...
ST ⇔ PQ ratio ST/PQ = 16.8/14 = 1.2
TU ⇔ QR ratio TU/QR = x/10 = 1.2 ⇔ x = 12
US ⇔ RP ratio US/RP = 18/15 = 1.2
The perimeter of ∆STU is the sum of its side lengths ...
16.8 +12 +18 = 46.8 . . . units
_____
Additional comment
The perimeter of PQR is 14 +10 +15 = 39. The scale factor applies to the perimeter, just as it does to the side lengths.
The perimeter of STU is 1.2×39 = 46.8.

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface.
