Answer:
No, the simplification is not done correctly. When multiplying
[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.
the correct answer is 12k-8
Step-by-step explanation:
We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.
The steps given are:
[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11[/tex]
No, the simplification is not done correctly. When multiplying
[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.
Correcting the error:
[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8[/tex]
So, the correct answer is 12k-8

What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to
solve.
Answer:
x= −41 /20
Step-by-step explanation:
(2x+3)(2)+8(2x+3)+11=0
(4x+16x)+(6+24+11)=0(Combine Like Terms)
20x+41=0
20x+41=0
Step 2: Subtract 41 from both sides.
20x+41−41=0−41
20x=−41
Step 3: Divide both sides by 20.
20x /20 = −41 /20
x= −41 /20

x2-16= -2x - 1
Please help
Answer:
The solutions are -5 and 3.
Step-by-step explanation:
[tex]x^2 - 16 = -2x-1[/tex]
[tex]x^2 - 16 +2x+1=0[/tex]
[tex]x^2 +2x-15=0[/tex]
Factoring the quadratic expression:
[tex](x+5)(x-3)= x^2 +2x-15=0[/tex]
So,
[tex]x+5 = 0 \implies x =-5[/tex]
[tex]x-3 = 0 \implies x =3[/tex]
Solve. 7w - 12 = 44 w = *
Answer:
[tex] \huge{ \boxed{ \bold{ \text{w = \: 8}}}}[/tex]
☃ Question : Solve for w[tex] \text{7w - 12 = 44 }[/tex]
✎ Step by step explanation[tex] \text{7w - 12 = 44}[/tex]
Move 12 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{7w = 44 + 12}}[/tex]
Add the numbers : 44 and 12
[tex] \longrightarrow{ \sf{7w = 56}}[/tex]
Divide both sides by 7
[tex] \longrightarrow{ \sf{ \frac{7w}{7} = \frac{56}{7}}} [/tex]
[tex] \longrightarrow{ \boxed{ \bold{ \red{ \sf{w = 8}}}}}[/tex]
--------------------------------------------------------------------
☟ Let's check whether the value of w is 8 or not !
✑ Verification :L.H.S ( Left hand side ) :
[tex] \dashrightarrow{ \sf{7w - 12}}[/tex]
plug the value of w and simplify
[tex] \dashrightarrow{ \sf{7 \times 8 - 12}}[/tex]
[tex] \dashrightarrow{ \sf{56 - 12}}[/tex]
[tex] \dashrightarrow{ \sf{ 44}}[/tex]
R.H.S ( Right Hand Side ) = 44
L.H.S = R.H.S ( Hence , the value of w is 8 ).
-----------------------------------------------------------------
☄ Rules for solving an equation :If an equation contains fractions , multiply each term by the LCM of denominators.Remove the brackets , if any.Collect the terms with the variable to the left hand side and constant terms to the right hand side by changing their signs ' + ' into ' - ' and ' - ' into ' + ' .Simplify and get the single term on each side.Divide each side by the coefficient of variable and then get the value of variable.Hope I helped !

From the information given, can you prove that the triangles congruent using SAS congruent postulate? If not, what do you need to know to make the triangle congruent using the SAS congruence postulate?
Answer:
D.
Step-by-step explanation:
to prove congruency of two triangles, you need two congruent sides and one congruent angle
in this case we are given exactly that, 2 sides and one angle that is congruent
we would also need to make sure that the given sides and angles are actually congruent, and not mismatched
we can do this by looking at the positions of the letters in each congruency statement
for example, the letters LO and MA are the first two letters in each triangle's name, this means that they are congruent and properly matched
if you do this with every statement that you are give, you can see that the triangles can be proven by SAS
A linear function contains the following points.
What are the slope and y-intercept of this function?
A. The slope is -3.

B. The slope is 1/3
The y intercept (0,-7)
c. The slope is -1/3
The y intercept s (0, -7).
D. The slope is -1/3
The y intercept is (-7,0)
Answer:
C
Step-by-step explanation:
PLEASE HELP!!Choose the slope and y-intercept that
correspond with the graph.
the answer is -1/3 y-incercept= -1
Answer:
The first one
Step-by-step explanation:
It’s y intercept is 1 and the slope is 1/3 because it goes up one and to the left 3 . I know it’s negative because it’s going down to the right.

Let f(x)=22−8−9.
(i)Write down the coordinates of the vertex.
(ii)Hence or otherwise, express the function in the form f(x)=2(−ℎ)2+.
b.Solve the equation f(x)=0.
There appears to be a typo in your function.
Note: f(x) = 22-8-9 is not a function. The notation f(x) means there should at least one x on the right side. Repost.

Which expression is equivalent to 8c + 6 - 3c - 2 ?
A)5c + 4
B)5c + 8
C)11c + 4
D)11c + 8
Answer:
I believe the answer is 5c + 4.
Step-by-step explanation:
The first step in simplifying expressions like this is to combine the values with the same coefficient and rearrange them so that they are next to each other in the expression. When you do this, you also have to keep the operation that comes before it if possible. 8c + 6 -3c - 2 will be turned into 8c - 3c + 6 - 2. Now you can simplify the expression in different parts. 8c - 3c = 5c, and 6 - 2 = 4. Keep the addition operation in the middle and combine the numbers:
5c + 4.

Two ships set sail in different directions from the same place. Tyler's ship sail 35 miles while Noah's ship sails for 42 miles. At the same time they are 56 miles apart. What was the angle between their paths when they started?
Answer:
The angle between their paths when they started is 93°.
Step-by-step explanation:
The Law of Cosines
It relates the length of the sides of a triangle with one of its internal angles.
Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:
[tex]c^2=a^2+b^2-2ab\cos x[/tex]
When the two ships travel in different directions from the same point in the plane, they form an angle we called x in the image below.
Tyler's ship sails a=35 miles and Noah's ship sails for b=42 miles. At some time they are c=56 miles apart.
Since we know the values of all three side lengths, we solve the equation for x:
[tex]\displaystyle \cos x=\frac{a^2+b^2-c^2}{2ab}[/tex]
Substituting values:
[tex]\displaystyle \cos x=\frac{35^2+42^2-56^2}{2(35)(42)}[/tex]
Calculating:
[tex]\displaystyle \cos x=-\frac{147}{2940}=-\frac{1}{20}[/tex]
Computing the inverse cosine:
[tex]x = \arccos(-0.05)[/tex]
[tex]x \approx 93^\circ[/tex]
The angle between their paths when they started is 93°.

Answer: 80
Step-by-step explanation:
First you split the shape into simple parts, and think about the measurements when you do so. Although you can't see my work, the way I split it is a rectangle that measures 8 by 4, and a rectangle that measures 8 by 6. You find the answer to these separately (32 and 48) and add them together (80).
