since its closed its ≤ and going to the left means less than or equal to. :D
Three-fifths of the sum K and 6 plus the product of 8 and x
Answer
3/5=k6+8x
Step-by-step explanation:
Simplifying
2(k + -5) + 3k = k + 6
Reorder the terms:
2(-5 + k) + 3k = k + 6
(-5 * 2 + k * 2) + 3k = k + 6
(-10 + 2k) + 3k = k + 6
Combine like terms: 2k + 3k = 5k
-10 + 5k = k + 6
Reorder the terms:
-10 + 5k = 6 + k
Solving
-10 + 5k = 6 + k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-1k' to each side of the equation.
-10 + 5k + -1k = 6 + k + -1k
Combine like terms: 5k + -1k = 4k
-10 + 4k = 6 + k + -1k
Combine like terms: k + -1k = 0
-10 + 4k = 6 + 0
-10 + 4k = 6
Add '10' to each side of the equation.
-10 + 10 + 4k = 6 + 10
Combine like terms: -10 + 10 = 0
0 + 4k = 6 + 10
4k = 6 + 10
Combine like terms: 6 + 10 = 16
4k = 16
Divide each side by '4'.
k = 4
Simplifying
k = 4

If f(x) = 4x ^ 2 - 6 and g(x) = x ^ 2 - 4x - 8 , find (f - g)(x)
A. (f - g)(x) = 3x ^ 2 - 4x - 2
B. (f - g)(x) = 3x ^ 2 + 4x + 2
C. (f - g)(x) = 5x ^ 2 - 4x - 14
D. (f - g)(x) = - x ^ 2 - 14
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= (4x² - 6) - (x² - 4x - 8)
= 4x² - 6 - x² + 4x + 8
= 3x² + 4x + 2. (B)

Determine how the triangles are similar, if possible.
A: SAS
B: AA
C:Not similar
D: SSS
Answer:
The two triangles are similar by SAS postulate of similarity ⇒ A
Step-by-step explanation:
Let us revise the cases of similarity
AAA similarity: two triangles are similar if all three angles in the first triangle equal the corresponding angle in the second triangle AA similarity: If two angles of one triangle are equal to the corresponding angles of the other triangle, then the two triangles are similar. SSS similarity: If the corresponding sides of the two triangles are proportional, then the two triangles are similar. SAS similarity: In two triangles, if two sets of corresponding sides are proportional and the included angles are equal then the two triangles are similar.In the given figure
∵ There are 2 triangles
∵ The ratio between 2 corresponding sides in the Δs is [tex]\frac{28}{40}[/tex]
∵ [tex]\frac{28}{40}[/tex] = 0.7
∵ The ratio between the other 2 corresponding sides in the Δs is [tex]\frac{42}{60}[/tex]
∵ [tex]\frac{42}{60}[/tex] = 0.7
→ That means 2 sets of corresponding sides have an equal ratio
∴ The 2 sets of corresponding sides are proportional
→ By using the parallel sides
∵ There are two parallel sides
∴ The angles between the sides 28, 42, and the sides 40, 60 equal
because they are corresponding angles
∴ The included angles are equal in measures
→ By using case 4 above
∴ The two triangles are similar by SAS postulate of similarity

Find the measure of AngleQ, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. Round the measure to the nearest whole degree.
Answer:
41
Step-by-step explanation:
41 degrees is the measure of AngleQ, when the smallest angle in a triangle whose sides have lengths 4, 5, and 6.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given the side lengths PR = 4, RQ = 6 and PQ = 5
According to the law of cosine,
c=√a²+b²-2abcosФ
Substituting the values,
4=√5²+6²-2×5×6 cos∠Q
4=√25+36-60 cos∠Q
4=√25+36-60 cos∠Q
Take square on both sides
16=25+36-60 cos∠Q
16=61-60 cos∠Q
16-61=-60cos∠Q
-45=-60cos∠Q
Divide both sides by 60
cos⁻¹(45/60)=∠Q
41=∠Q
Hence, the measure of ∠Q is 41 degrees.

3.) Solve:
5x + 3- 3x = 2(x + 3) - 5
Answer:
0 = -2
Step-by-step explanation:
Answer:
no answer.
Step-by-step explanation:
5x + 3 - 3x = 2(x + 3) - 5 Simplify the left.
2x + 3 = 2(x + 3) - 5 Remove the brackets
2x + 3 = 2x + 6 - 5 Simply the right
2x + 3 = 2x + 1
It doesn't matter what you do, this is going to give you an impossible answer. The 2x's will cancel out and you will get 3 = 1 which is impossible.

What is the next term of the arithmetic sequence?
-2, 3, 8, 13, 18,
Answer:
[tex]\boxed{\boxed{\sf~a_6=23}}[/tex]
Solution Steps:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 5 to the previous term in the sequence gives the next term. In other words, [tex]a_n=a_1+d(n-1)[/tex].
Arithmetic Sequence: [tex]d=5[/tex]
Find the next term using the Arithmetic Sequence.
Arithmetic Sequence: [tex]a_6=a_5+5[/tex]
[tex]a_6=18+5=23[/tex]
What polyominal should be subtracted from 3x^2+4x-1 to get the difference equal to x^2
Step-by-step explanation:
(3x² + 4x - 1) - ? = x²
Therefore ? = (3x² + 4x - 1) - x² = 2x² + 4x - 1.
The polynomial that should be subtracted is 2x² + 4x - 1.

Answer:
x = 47°
Step-by-step explanation:
In a kite the main diagonal AC bisects the opposite angles, then
∠ BAE = ∠ DAE = 43° , then ∠ A = 86°
Since AB and AD are congruent then Δ ABD is isosceles and the base angles are congruent, thus
x = [tex]\frac{180-86}{2}[/tex] = [tex]\frac{94}{2}[/tex] = 47°
Solve 13+b>34. Graph the solution.
I give lots of points
Question:
13 + b > 34
Step 1: Keep variable on one side, and subtract 13 on both sides.
b > 21
Step 2: Now that you have the value of b, create a number line that includes the number "21"
Step 3: Since it is not "or equal too" we will use an open dot, since we do not contain that point. Put dot over 21.
Step 4: The sign is ( > ) meaning greater than. Therefore all points greater than 21 is true. See graph.
