#1The system of equations:
2x + 7y = -113x + 5y = -22Solve by elimination.
Triple the first equation, double the second one, subtract the second from the first and solve for y:
3(2x + 7y) - 2(3x + 5y) = 3(-11) - 2(-22)6x + 21y - 6x - 10y = -33 + 4411y = 11y = 1Find x:
2x + 7*1 = -112x = -11 - 72x = -18x = -9The solution is:
x = -9, y = 1#2Simplifying in steps:
8u - 29 > -3(3 - 4u)8u - 29 > - 9 + 12u12u - 8u < -29 + 94u < -20u < -5formula to calculate area of quadrilateral when Co ordinates are given please answer it anyone please...

Answer:
y=3
Step-by-step explanation:
6=2(y+2)-4
6=2y+4-4
6-4+4=2y
6=2y
3=y
The answer you are looking for is y=3.
Solution/Explanation:
First, writing out the problem,
6=2(y+2)-4.
Next, using the Distributive Property for 2(y+2), which is 2y+4,
6=2y+4-4.
Now, canceling out the 4, since 4-4=0,
6=2y+0, or 6=2y.
Finally, dividing both sides by 2,
6/2=2y/2.
6/2=3.
2y/2=y.
3=y, or y=3.
So, therefore, the final answer is y=3.
I hope that this has helped answer your question. Good day to you.

Solve the equation for the indicated variable.
y(a-b)=c(y+a);y
Answer:
y = [tex]\frac{ac}{a-b-c}[/tex]
Step-by-step explanation:
Given
y(a - b) = c(y + a) ← distribute parenthesis on both sides
ay - by = cy + ac ( subtract cy from both sides )
ay - by - cy = ac ← factor out y from each term on the left side
y(a - b - c) = ac ← divide both sides by a - b - c
y = [tex]\frac{ac}{a-b-c}[/tex]
The value of y is ac/ (a-b-c)
What is an equation?An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.
For example, 3y = 16 is an equation.
Given equation:
y(a-b)=c(y+a)
Now, using distributive property
ay-by = cy + ac
ay-by-cy = ac
y(a-b-c)=ac
y= ac/ (a-b-c)
Hence, the value of y is ac/ (a-b-c).

The line (y-1)=(2/3)(x+1) contains point (a,-3).
What is the value of a? Show
your work.
Answer:
-7
Step-by-step explanation:
The line (y-1)=(2/3)(x+1) contains point (a,-3)
=> (-3-1) = (⅔)(a+1)
-4 = (⅔)(a+1(
(a+1)= -4 ÷ ⅔
a + 1 = -4 × 3/2
a+ 1 = -6
a = -6-1
a = -7
The value of 'a' will be;
⇒ a = - 7.
What is substitution method?To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation of line is,
⇒ (y - 1) = (2/3) (x + 1)
And, The point on the line = (a, - 3)
Now,
Since, The point on the line = (a, - 3)
Hence, It satisfy the equation of line.
Substitute x = a and y = - 3, we get;
⇒ (y - 1) = (2/3) (x + 1)
⇒ (- 3 - 1) = (2/3) (a + 1)
⇒ - 4 × 3 = 2a + 2
⇒ - 12 - 2 = 2a
⇒ 2a = - 14
⇒ a = - 7
Thus, The value of a = - 7

Answer:
Step-by-step explanation:
Temperature at 5 am = -7° F
Temperature at 9 am = 4° F

Total increase = 18 - (-4) = 18 + 4 = 22° F
Cindy multiple her age by 5, subtracted 12, and then divide by 3. The result was 16. How old is Cindy?
Let's give Cindy's age a variable.
Cindy's age = x
Cindy multiplies her age by 5
x(5)
Subtracted by 12
x(5) - 12
Divide by 3
(5x - 12)/3
The result was 16
(5x - 12)/3 = 16
Let's solve
Multiply both sides by 3
(5x - 12) = 48
Open brackets
5x - 12 = 48
Add 12 to both sides
5x = 60
Divide by 5 on both sides to isolate x
x = 12
Cindy is 12 years old.

Simplify 4^2 ⋅ 4^8.
A)4^16
B)4^10
C)1^616
D)1^610
You will get 27pts if you answer this!!!
Answer:
4^2 * 4^8 = B)4^10
Step-by-step explanation:
When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.
given xz with x(1,9) and z(5,-11) if y lies on xz such that the ratio of xy to xz 1:4, find the coordinates of y
If a segment XZ joining two endpoints X[tex](x_1,y_1)[/tex] and Z[tex](x_2,y_2)[/tex] is divided by a point Y(x, y) externally in the ratio of m : n,
Coordinates of the point will be,
x - coordinates → [tex]\frac{mx_2-nx_1}{m-n}[/tex]
y - coordinates → [tex]\frac{my_2-ny_1}{m-n}[/tex]
If the coordinates of the endpoints X and Z are (1, 9) and (5, -11) respectively and the ratio in which a point Y divides the segment is 1 : 5,
(Since, XY : XZ = 1 : 4 therefore, XY : YZ = 1 : 5)
Therefore, coordinates of Y will be,
x- coordinates → [tex]\frac{1(5)-5(1)}{1-4}=0[/tex]
y-coordinates → [tex]\frac{1(-11)-5(9)}{1-5}=\frac{-56}{-4}=14[/tex]
Therefore, coordinates of Y will be [tex](0,14)[/tex].
