∆ has the coordinates (3, 1), (5, 2), (4, 3). ∆´´´ has coordinates (-1, 2), (1, 3) and (0, 4). Which choice describes the translation of ∆ to ∆´´? A +4 units in the direction of x and -1 units in the direction of y B -4 units in the direction of x and +1 units in the direction of y C +4 units in the direction of x and +1 units in the direction of y D -4 units in the direction of x and -1 units in the direction of y
Answer:
B -4 units in the direction of x and +1 units in the direction of y
Step-by-step explanation:
Given
[tex]A = (3, 1), (5, 2), (4, 3)[/tex]
[tex]A^{-1}= (-1, 2), (1, 3) (0, 4)[/tex]
Required
Determine the translation from A to A-1
Take (3,1) from A and (-1,2) fro A-1 as points of reference,
For translation to occur, we make use of:
[tex](3 + x,1+y) = (-1,2)[/tex]
By comparison:
[tex]3 + x = -1[/tex] and [tex]1 + y = 2[/tex]
Solve for x and y
[tex]3 + x = -1[/tex]
[tex]x = -1-3[/tex]
[tex]x = -4[/tex]
[tex]1 + y = 2[/tex]
[tex]y = 2 - 1[/tex]
[tex]y=1[/tex]
(B) is correct.
At Jefferson Middle School, eighty-two students were asked which sports they plan to participate in for the coming year. Twenty students plan to participate in track and cross country; six students in cross country and basketball; and eight students in track and basketball.

What in a region can be affected by latitude, topography, altitude and closeness to a large body of water, jet streams and surface currents?
Answer:
Hey!
Step-by-step explanation:
Latitude, or how far one is from the equator, greatly affects the climate and weather of an area. If you live close to the equator, the climate will be warmer, while moving north or south from the equator brings a cooler climate. Altitude, or how high one is above sea level, has a similar effect–the higher the elevation, the colder the climate.
Hope this helps! :)

Which set of ordered pairs (x, y) could represent a linear function?
A = {(3,5), (5,1), (7, -2), (9,-6)}
B = {(2,-5), (5,1), (6,3), (7,6)}
C = {(-4,3), (-2,0), (0, -4), (2, –7)}
D = {(-3,7), (-1,5), (1,3), (3, 1)}
Answer = C
because all are not in set pairs only no. C is pair of set

Answer:
y- intercept = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
f(x) = [tex]\frac{1}{2}[/tex] [tex](6)^{x}[/tex]
To find the y- intercept let x = 0 , then
f(0) = [tex]\frac{1}{2}[/tex] [tex](6)^{0}[/tex] [ [tex]6^{0}[/tex] = 1 ]
= [tex]\frac{1}{2}[/tex] × 1 = [tex]\frac{1}{2}[/tex] ← y- intercept

Find the perimeter of an equilateral triangle that has an attitude of 25 inches. Round your answer to the nearest 10
9514 1404 393
Answer:
86.6 inches
Step-by-step explanation:
The side length of an equilateral triangle is 2/√3 times the altitude. So, the perimeter is ...
P = 3s = 3(25)(2/√3) = 50√3 ≈ 86.6 . . . . inches

Answer:
[tex] x = 4 \sqrt{2} [/tex]
[tex] y = 4 \sqrt{6} [/tex]
Step-by-step explanation:
[tex] \sin 45 \degree = \frac{x}{8} \\ \\ x = 8 \sin 45 \degree \\ \\ x = 8 \times \frac{1}{ \sqrt{2} } \\ \\ x = \frac{8 \sqrt{2} }{2} \\ \\ x = 4 \sqrt{2} \\ \\ \\ \tan 30 \degree = \frac{x}{y} \\ \\ \frac{1}{ \sqrt{3} } = \frac{4 \sqrt{2} }{y} \\ \\ y = 4 \sqrt{6} [/tex]
A car dealership sells sedans and SUVs. In 2000, the ratio in which they were sold was 5:4. By 2010, the dealership had adjusted its inventory to a 2:7 ratio. If it sold 84 SUVs in 2010, how many sedans did it sell in 2000?
Answer:
60 sedans
Step-by-step explanation:
The computation of the number of sedans sold in 2000 is given below:
Given that
The ratio of sedans and SUV is 5:4
And, in 2010 its ratio is 2:7
Now in 2010, 84 SUVs sold
So
84 SUVS = 7
For total 9, it would be
= 84 × 9 ÷ 7
= 108 vehicles
Now the number of sedans is
= 108 × 5 ÷ 9
= 60 sedans
