Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.
Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
Your solution is (6, -7).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-8x - 5y = -13
-4x - 5y = 11
Let's change the second equation into one with one variable on each side.
-5y = 4x + 11
y = -4/5x - 11/5
Now, plug this into your first equation.
-8x - 5(-4/5x - 11/5) = -13
Distribute the -5 sign.
-8x + 4x + 11 = -13
Combine the like terms.
-4x + 11 = -13
-4x = -24
Isolate x by dividing both sides by -4.
x = -24/-4
x = 6
Now plug this back into either equation.
y = -4/5(6) - 11/5
Multiply.
y = -24/5 - 11/5
Subtract.
y = -35/5
Simplify.
y = -7
Your solution is (6, -7).
Check this by plugging in these values into the equation you have not checked yet.
-8(6) - 5(-7) = -13
-48 + 35 = -13
-13 = -13
Your solution is correct.
Hope this helps!

x = -3i, x = 2 and the third zero is x = 3iPolynomial is:
(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 182.
Zeros:
x = 3, x = 3, x = -1Polynomial is:
(x - 3)(x - 3)(x + 1) = (x² - 6x + 9)(x + 1) =x³ + x² - 6x² - 6x + 9x + 9 =x³ - 5x² + 3x + 9Helppppppppppp

What does 2/3 + 1/3 + 5/3 equal?
A bag contains 5 red marbles, 3 blue marbles, 7 yellow marbles, and 2 green marbles. Which ratio can be used to compare the red
marbles to the blue marbles?
A) 3/5
B) 3/8
C) 5/3
D) 5/8
Answer:
C) 5/3
Step-by-step explanation:
The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles
This gets you 5/3
So, the correct answer is C) 5/3
Answer:
5/3
Step-by-step explanation:
This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.
Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

Dilate Point B by a scale factor of 3:
(12,12)
(12,0)
(0,12)
(4,3)
We can write the coordinates of the vertices of the triangle after dilation by a scale factor as -
C'(9, 6)
B'(0, 12)
A'(12, 12)
What is dilation?Dilation is the enlargement or shrinking of the coordinates.
Given is a triangle as shown in the image.
The coordinates of the vertices of the triangle are -
C(3, 2)
B(0, 4)
A(4, 4)
For the dilation by a scale factor of {K} = 3, we can write -
C'(3 x 3, 2 x 3) = C'(9, 6)
B'(0 x 3, 4 x 3) = B'(0, 12)
A'(4 x 3, 4 x 3) = A'(12, 12)
Therefore, we can write the coordinates of the vertices of the triangle after dilation by a scale factor as -
C'(9, 6)
B'(0, 12)
A'(12, 12)
