Answer:
x=15/4,y=-8.25
Step-by-step explanation:
Well to begin with it make both y's equal so multiply the first equation by 3 making it into: 6.6x+3y=-12. next subtract this new equation by the other one making it one equation as, 1.6x=-6, simplify to get: x=15/4, or 3.75 input that into one of the equations the secound one would be easier to make it 18.75+3y=-6 simplify again, 3y=-24.75 than you get y as y=-8.25

. XYZ has vertices X (–5, 2), Y (0, –4), and Z (3, 3). What are the vertices of the image of X’Y’Z’ under the translation (x, y) → (x + 7, y – 5) ?
Answer:
X' = (2, -3)
Y' = (7, -9)
Z' = (10, -2)
Step-by-step explanation:
to find the translation of each point substitute the x and y with the the numbers
eg; X ( -5,2) the x is 5 and the y is 2
so -5 + 7 = 2 (the x value)
2 - 5 = -3 ( the y value)
find z and x

A sum of 2440 is made up of N100 and N10 notes. There are 6 times as many N100 notes as
there are N10 notes. Find the number of N100 notes.
The number of N 100 notes in the 2440 is 24 notes
What is proportion?A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4.
Relating the example with the question , for every 6, N100 notes there is 1, N10 notes . This means the ratio of N100 note to N10 note is 6:1
Therefore for every N600 there will be 10N
following the trend, for every N1200 there will be N20. for every N1800 there will be N30 and for every N2400 there will be N40
The addition of 2400+40= 2440
This means that the sum of N100 is 2400
Therefore the number of N100 is 2400/100= 24 notes

If the radius of a circle is cut in half, what is the scale factor needed to adjust the area of the original circle to the smaller circle?
When the radius is halved, your area will be divided by 4. If you think about it, radius is already half of the diameter so your area is already divided by 2, so if you cut the radius is half again, your area will be divided by 4.
