Emily is solving the following System of equations using Substitution:
y=3x-4
y=2x+1
Her steps are shown below.
Part A
Click on the first step in which Emily made an error.
3x-4=2x+1
5x-4=1
5x=5
x=1
y=3(1)-4=3-4=-1
(1,-1)
Part B
Explain what Emily did wrong and then what she should have done to make sure it was the correct answer.
Answer:
Emily is solving the following system of equations using substitution:
y = 3x - 4
y = 2x + 1
Part A:
After substituting y's values:
3x - 4 = 2x + 1
What she did:
3x - 4 = 2x + 1
3x + 2x - 4 = 1
5x - 4 = 1
What she should have done:
3x - 4 = 2x + 1
3x - 2x - 4 = 1
x - 4 = 1
Part B:
This rule has not been followed: Sign changes when numbers shift from left to right of ' = 'sign.
Emily did not changed the sign of the number, 2x from + 2x to - 2x when it was moved from the right side to the left.

Answer:
The surface area of the parallelogram is;
2x^3 -6x^2 - 14x +24 squared centimeters
Step-by-step explanation:
To get the area of the parallelogram, we need to multiply the base length of the parallelogram by the height of the parallelogram
We have this as follows;
(x-4)(2x^2+2x-6)
= x(2x^2 + 2x-6) -4(2x^2 + 2x-6)
= 2x^3 + 2x^2 - 6x -8x^2 -8x + 24
= 2x^3 +2x^2 -8x^2 -6x-8x+24
= 2x^3 -6x^2 - 14x +24

Explain how changes in the dimensions of a cube dimensions affect the volume of a cube. Be specific, explaining how much the volume will change with each increase of 1 unit on the side lengths. Please give a clear explanation!
Answer:
When the dimensions of the shape, such as radius, height, or length change, both surface area and volume also change. However, the volume of the object always changes more than the surface area for the same change in dimensions.

Please help me
can u explain how to do this
Answer:
x=41
Step-by-step explanation:
so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:
a^2+b^2=c^2
so:
9^2 +40^2=c^2
solve for the exponents:
81 +1600=c^2
1681=c^2
and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41
hope this helps :)

i can't see the 4th option but from what i can see, i'd say 20 (b).
i didn't do math for this, i just used context clues.
the hypotenuse is always longer than either of the sides, so if the hypotenuse is 29, then the only logical solution is 20 feet. every other option is >29.
Answer:
Hello! answer: 20 feet
Step-by-step explanation:
29 × 29 = 841 21 × 21 = 441 841 - 441 = 400 √400 = 20 20 × 20 = 400 therefore 20 is the answer Hope that helps!

Solve the equation
2x2 + 8x – 1 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Step-by-step explanation:
[tex] {2x}^{2} + 8x - 1 = 0 \\ {x}^{2} + 4x - \frac{1}{2} = 0 \\ {x}^{2} + 4x + {( \frac{1}{4} )}^{2} - \frac{1}{2} - { (\frac{1}{4} )}^{2} = 0 \\ {(x + \frac{1}{4}) }^{2} - \frac{9}{16} = 0 \\ {(x + \frac{1}{4}) }^{2} = \frac{9}{16} \\ x + \frac{1}{4} = ±( \frac{ 3}{4} ) \\ x = \frac{1}{2} \: or \: - 1[/tex]
Answer:
Step-by-step explanation:
divide each term by 2 to begin with x²
x² + 4x - 1/2 = 0
now add 1 to each side
x² + 4x = 1/2
now divide 4 in half and square the result and add it to each side
x² + 4x + 4 = 1/2 + 4
(x + 2)² = 9/2
y= 4x + 2
y= 4x + 6
How many solutions
0 solutions.
4x+2 is not = 4x+6
Therefore there will be Jo solutions
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = 4x + 2 → (1)
y = 4x + 6 → (2)
Substitute y = 4x + 2 into (2)
4x + 2 = 4x + 6 ( subtract 2 from both sides )
4x = 4x + 4 ( subtract 4x from both sides )
0 = 4 ← not possible
This indicates the system has no solution
find the simple interest on Birr 700 at 12% rate for 3 months
Answer:
252
Step-by-step explanation:
700 mutliply by 12 divided by 100 is equall to 8484multiply by 3 is equall to 252One-sixth of a certain number is four more
than one-twelfth the number. Find the number. a. 6 b. 18 C. 36 d. 48
let number be x
1/6x - 1/12x= 4
1/12x=4
cross multiply
x= 12 x 4
x= 48
If one-sixth of a certain number is four more than one-twelfth the number, the required number will be 48.
Let the unknown number be 'a'
One-sixth of the number is expressed as 1/6 a ..... 1
One-twelfth the number is also expressed as 1/12 a
Four more than one-twelfth the number will be written as:
1/12 a + 4 .... 2
Equating 1 and 2 will give:
1/6 a = 1/12 a + 4
a/6 = a/12 + 4
Collect the like terms
[tex]\frac{a}{6} - \frac{a}{12} = 4[/tex]
Find the LCM
[tex]\frac{2a-a}{12} = 4\\\frac{a}{12} = 4[/tex]
Cross multiply
a = 12×4
a = 48
This shows that the required number is 48

[tex]\frac{10}{7}\cdot a^{3}\cdot y^{4} - \frac{1}{7}\cdot a^{4}\cdot y^{3} - \frac{5}{21}\cdot a^5\cdot y^{2}}[/tex]
Step-by-step explanation:
According to the statement, we have the algebraic equation[tex]\frac{2}{7}\cdot {a^{2}\cdot y^{2}}\cdot \left(5\cdot a\cdot y^{2} - \frac{1}{2}\cdot {a}^{2}\cdot y - \frac{5}{6}\cdot a^{3}\right)[/tex] and we must to rewrite it as a polynomial. Since there are two variables: [tex]a[/tex], [tex]y[/tex], we must observe the following definition of polynomial:
[tex]p(a, y) = \Sigma\limits_{i = 0}^{n} c_{i}\cdot a^{i}\cdot y^{n-i}[/tex] (1)
Where:
[tex]i[/tex] - Index.
[tex]c_{i}[/tex] - i-th Coefficient of the polynomial.
[tex]n[/tex] - Grade of the polynomial.
By means of algebraic handling, we have the following result:
1) [tex]\frac{2}{7}\cdot {a^{2}\cdot y^{2}}\cdot \left(5\cdot a\cdot y^{2} - \frac{1}{2}\cdot {a}^{2}\cdot y - \frac{5}{6}\cdot a^{3}\right)[/tex] Given
