Use the image to determine the type of transformation shown.
Horizontal translation
Reflection across the y-axis
90° clockwise rotation
90° counterclockwise rotation
Answers
If it were a horizontal translation, it would’ve been going left to right, which it isnt.
If it were reflected over the y-axis, the points wouldve just been reflected over to the other side, which its also not.
The 90° counterclockwise rotation is simply going the wrong way, so the 90° clockwise rotation has to be the answer.
Hope this helps! :)
Answer:
90° clockwise rotation
Step-by-step explanation:
A horizontal translation would have left the shape pointing in the same direction.
A reflection across the y-axis would bring it to a quadrant that is not shown.
90 degree counterclockwise rotation would have again taken the shape to a quadrant that is not shown.
The other answer is also correct. Their reasoning may help you understand it better, because people learn in different ways. So, I encourage that you read that as well.

Answer:
Step-by-step explanation:
It's B.
Let's rewrite the expression like this :
2x+y=12 ⇒ y=12-2x
and try given values for x :
if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrongThe table shows the number of goals made by two hockey players.

Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

The Khan family is constructing a backyard and needs your help with a design that will fit their budget. The backyard is in the shape of a rectangle. They need to place a new layer of grass to cover their backyard, and they would like to build a circular pool with a surrounding deck (also circular). The pool is also 2 meters in height. Once the pool has been installed they need to paint the outside surface with a special material to protect the pool from rust. Their budget for this renovation is $9000.
The cost for each part of their renovation is as follows:
$5000 to install the pool
$2.20 per meter squared to layer the backyard with grass
$4.75 per meter squared to install the deck
$6.15 per meter squared to paint the outside surface of the pool with a special material

A, B and Care points on a circle, centre 0
Angle ABC = 389
Work out the size of angle OAC
Give a reason for each stage of your working
Answers
Answer:
m(∠OAC) = 52°
Step-by-step explanation:
A, B and C are the pints on a circle with center O.
m(∠ABC) = 38°
By the central angle theorem,
"Central angle subtended by two points on a circle measure the twice of the inscribed angle subtended by these points."
m(∠AOC) = 2m(∠ABC)
m(∠AOC) = 2 × 38° = 76°
Now in ΔAOC,
AO and OC are the radii, so the angles opposite to radii will measure the same.
∠OAC ≅ ∠OCA
Since, sum of all the interior angles of a triangle is 180°.
m(∠OAC) + m(∠OCA) + m(∠AOC) = 180°
m(∠OAC) + m(∠OAC) + 76° = 180°
2m(∠OAC) = 180° - 76°
2m(∠OAC) = 104°
m(∠OAC) = 52°

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given that,
For breakfast, Mr hill bought a cup of coffee for \(1.39\) and a bagel for \(1.85\).
So, the total he bought is \(1.39+1.85=3.24\)
He has the savings \(5.00\)
