(5, 2);
2x +y= 12
—3y - х = -11
I’m confused help !
Answer:
so (5;2) belongs to these equaliations
Step-by-step explanation:
(5;2) is the same as (x;y)
so u just plug in your numbers
—3y - х = -11
-3*2-5=-11
-6-5=-11
-11=-11
2x +y= 12
2*5+2=12
12=12

What is the image point of (4,5)(4,5) after a translation left 5 units and down 3 units?
Answer:
The image of point (-1,2)
Step-by-step explanation:
Step(i):-
Given point ( 4,5)
The Horizontal translation left '5' units then the transformed to
(x ,y ) → (x - 5 ,y)
(4,5)→ (4-5 , 5)
Step(ii):-
Again the vertical translation down '3' units then transformed to the co-ordinate point is (x, y)→ ( x, y-3)
(4-5 , 5)→ ( 4-5 , 5 -3)
(-1 , 5) → (-1 , 2)
Final answer:-
The image of point (-1,2)

The rainfall amount last year was 6 inches below normal. The rainfall this year was 13 inches more than last year. What is the difference between the rainfall amount this year and the normal amount of rainfall? (Hint: Draw a number line to help you visualize the scenario)
Answer:
7
Step-by-step explanation:
The term difference means to subtract. Therefore, 13in - 6in, is equal to 7 inches.
13-6=7

Solve the system of linear equations by using the elimination method:
4x+ y = 36
8x- y = 60
Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4

Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?
Answer:
There are 21 multiple-choice problems and 17 short answers.
Step-by-step explanation:
Let there are x multiple-choice problems and y short answers.
ATQ,
x+y = 38 ....(1)
Each a multiple-choice problem is worth two points and each short answer is worth three points.
2x+3y = 93 ....(2)
Multiply equation (1) by 2.
2x+2y = 76 ....(3)
Subtract equation (2) and (3) we get :
2x+3y-(2x+2y) = 93-76
2x+3y-2x-2y = 17
y=17
Put the value of y in equation (1).
x+17 = 38
x=21
Hence, there are 21 multiple-choice problems and 17 short answers

Answer: The answer is 96 wizards.
Step-by-step explanation:
So what I like to do is fraction formatting.
you start with x/blank [tex]\frac{blank}{120}[/tex] and [tex]\frac{80}{100}[/tex] you do cross multiply divide
and multiple 120 by 80(=9600) and divide by 100 (=96) because wizards are 20% less of the population than goblins, so they are equivalent to 80% of the goblins! Hope this helped!

•Subtract 16 and then divide by 6
•Divide by 6 and add 16
•Add 16 and then divide by 6
•Multiply by 6 and add 16
Answer:
in my opinion it should be Add 16 and then divide by 6
Step-by-step explanation:
Answer:
C. Add 16 and divide by 6
Step-by-step explanation:
If you add by 16 you will get a result of
54=6x
Then when you divide by 6 you will result in
9=x or x=9 which will solve the equation

Answer: 29
see in the picture, WX is the median of the trapezoid
=> WX = (ST + UV)/2
⇔ 7x + 8 = (10x + 5 + 8x - 1)/2
⇔ 7x + 8 = (18x + 4)/2
⇔ 7x + 8 = 9x + 2
⇔ 2x = 6
⇔ x = 3
with x = 3 => WX = 7.3 + 8 = 21 + 8 = 29

Answer:
a) 6b) 3t² - 17t + 28c) 3t² - 5t - 2Step-by-step explanation:
Given function:
g(t) = 3t² - 5t + 4a) g(2)
g(2) = 3*2² - 5*2 + 4 = 3*4 - 10 + 4 = 12 - 6 = 6b) g(t - 2)
g(t - 2) = 3(t - 2)² - 5(t - 2) + 4 = 3(t² - 4t + 4) - 5t + 10 + 4 = 3t² - 12t + 12 - 5t + 16 = 3t² - 17t + 28c) g(t) - g(2)
g(t) - g(2) = 3t² - 5t + 4 - 6 = 3t² - 5t - 2Find the values of x and y so that ABCD will be a parallelogram.
24°
(y – 10°
32°
(4x)
x = 20, y = 42
x = 6, y = 22
Ox=6, y = 42
x = 20, y = 22
Given:
Figure of a parallelogram.
To find:
The values of x and y.
Solution:
If two parallel lines intersected by a transversal line, then the alternate interior angles are congruent.
[tex]4x=24[/tex] (Alternate interior angles)
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
And,
[tex]y-10=32[/tex] (Alternate interior angles)
[tex]y=32+10[/tex]
[tex]y=42[/tex]
The value of x is 6 and the value of y is 42.
Therefore, the correct option is C.

Thank you so much God Bless you brother
Answer:
CD=10.15m
Step-by-step explanation:
Find the distance of BC.
Tan(40)=55/BC
BC=65.55m
Find the distance of BD.
Tan(36)=55/BD
BD=75.70m
Use BC and BD to find CD
BD-BC=CD
75.70-65.55=CD
CD=10.15m
Check all the true statements.
Answer:
The true statements are:
2DE = AC1/2AC = DEDE || ACStep-by-step explanation:
As we are given,
AD = 3.5 and BD = 3.5
CE = 3 and BE = 3
From the given triangle ΔABC, it is clear that:
The segment DE bisects the sides AB and BC, so
AD = BD
CE = BE
It is clear that the segment DE is parallel to the segment AC, thus
DE || AC
As DE is the midsegment between AB and BC, so
2DE = AC
1/2AC = DE
Thus, the true statements are:
2DE = AC1/2AC = DEDE || ACFred and Stacey both have books to read over the summer. Fred has read 42 pages and Stacey has read 49 pages. What is the ratio of the number of pages Stacey has read to the number of pages Fred has read?

Answer:
x = 41; B = 41°; A = 77°
Step-by-step explanation:
All of the angles add up to 180 so to solve for X you do (x) + (2x-5) + (62) = 180. Solve for X and you get 41. Lastly plut the answer back into the equation.
