Answer:
A) 90° counterclockwiseStep-by-step explanation:
Preimage (4, - 7) and image (7, 4).
Rule applied:
(x, y) → (-y, x), this is a 90° counterclockwise rotationCorrect choice is A
Answer:
Option A
Step-by-step explanation:
90° counterclockwise rotation about origin rule is
(x,y)=(-y,x)So here
(4,-7)Rotate it
(-(-7),4)(7,4)Option A is correct

cual es el menor numero cuya raiz cuadrada entera tiene dos cifras ?
Answer:
100
Step-by-step explanation:
The perfect square integers are:
1^2 , 2^2, 3^2, 4^2, 5^2, 6^2, ...
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, ...
We note from the list above that the smallest integer
whose square root is an integer of two digits is 100.
The next smallest perfect square is 81, and its square
root is 9, which is a one digit integer.
Y ∝ √ x If y = 42 when x = 9 find, y when x = 100
Answer:
y = 140
Step-by-step explanation:
Given y varies directly with [tex]\sqrt{x}[/tex] then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of variation
To find k use the condition y = 42 when x = 9 , then
42 = k [tex]\sqrt{9}[/tex] = 3k ( divide both sides by 3 )
14 = k
y = 14[tex]\sqrt{x}[/tex] ← equation of variation
When x = 100 , then
y = 14 × [tex]\sqrt{100}[/tex] = 14 × 10 = 140
Enter the equation of the line in any format that we have learned that passes the two points: (2, -5) and (0, 1).
Given points:
(2, -5) and (0, 1)Find the slope:
m = (1 - (-5))/(0 - 2) = 6/(-2) = -3Point - slope form:
y - (-5) = -3(x - 2) ⇒ y + 5 = -3(x - 2)Convert into slope- intercept form:
y = -3x + 6 - 5 ⇒ y = -3x + 1Convert into standard form:
3x + y = 1[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
let's find slope (m) :
[tex] \dfrac{y2 - y1}{x2 - x1} [/tex][tex] \dfrac{1 - ( - 5)}{0 - 2} [/tex][tex] \dfrac{6}{ - 2} [/tex][tex] - 3[/tex]Plugging value of x and y from point (0 , 1) and slope (m) = -3, in general equation of line we will get the value of y - intercept (c)
that is :
[tex]y = mx + c[/tex][tex]1 = (0 \times - 3) + c[/tex][tex]c = 1[/tex]y intercept (c) = 1, now let's plug the value of slope(m) and y - intercept (c) in general equation of line to get the required equation of line which passes from given two points.
[tex]y = - 3x + 1[/tex]Find the slope of the line that contains (2, -10) and (-4, 2).
Answer:
Slope: -2
Step-by-step explanation:
(2, -10) and (-4, 2).
m = y1 - y2 / x1 - x2
m = -10-2/2-(-4)
m = -12/6
m = -2
which is greater than
2 3/4 or 1.25
Answer:
2 3/4 is greater because 1.25 as a fraction is 5/4

Carlos is going on a boat tour the boat will travel a total distance of 35 km during the seven hour tour if the boat travels at a consistent speed during the torr what distance in kilometers should the boat travel in three hours
Answer:
We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers

what operation will eliminate the x variable in -6+6y=6
In the figure below, m
Il n ánd p || q. Find the values of x and y.
Answer:
114 and 30Step-by-step explanation:
The angles with measure of 66 and x are consecutive interior angles and therefore supplementary:
x + 66 = 180x = 180 - 66x = 114The angles x and 4y - 6 are alternate interior angles and therefore congruent:
x = 4y - 6114 = 4y - 64y = 114 + 64y = 120y = 120/4y = 30
