Complete a paragraph proof for: Given: -4k + 2(5k - 6) = 3k - 36 Prove: k=-8. can someone please help me
The value of k is proved to be -8
How to prove that the value of k is -8?The equation is given as
-4k + 2(5k - 6) = 3k - 36
Open the bracket in the above equation
So, we have
-4k + 10k - 12 = 3k - 36
Collect the like terms in the above equation
So, we have
-4k + 10k - 3k = 12 - 36
Evaluate the like terms in the above equation
So, we have
3k = -24
Divide both sides of the above equation by 3
So, we have
k = -8
Hence, the value of k is proved to be -8

You basically can solve for hypothetical sides of this triangle using sohcahtoa backwards. In the first column, it says that adjacent/hypotenuse = .97. We can come up with two values that satisfy this equation. For example, the adjacent side can be .97 and the hypotenuse can be 1. These values don't matter as long as adjacent/hypotenuse is .97.
The second column tells us that opposite/hypotenuse = .26. At this point, we already have a hypothetical hypotenuse with a length of 1, so we can plug that in and find that the opposite side of C is .26.
Now that we have a hypothetical triangle with sides .97, .26, and 1, you can use these values as well as sohcahtoa to solve for the rest with respect to angle A. Keep in mind that the line AB is .26 and that the line BC is .97.

half of a number, decreased by 10 is -13. in equation form pls
i will give first and best brainliest
Answer:
[tex]\dfrac{1}{2}x-10=-13[/tex]
Step-by-step explanation:
Let x be the unknown number.
Given:
Half of a number → ¹/₂xDecreased by 10 → -10Is -13 → = -13Therefore, the equation is:
[tex]\boxed{\dfrac{1}{2}x-10=-13}[/tex]
Solving for x
To solve, add 10 to both sides:
[tex]\implies \dfrac{1}{2}x-10+10=-13+10[/tex]
[tex]\implies \dfrac{1}{2}x=-3[/tex]
Multiply both sides by 2:
[tex]\implies 2 \cdot \dfrac{1}{2}x=2 \cdot -3[/tex]
[tex]\implies x=-6[/tex]
Equation :-
→ (1/2)x - 10 = -13
Solution :-
→ x = -6
Step-by-step explanation:
The equation will be,
→ (1/2)x - 10 = -13
Now the required value of x will be,
→ (1/2)x - 10 = -13
→ (1/2)x = -13 + 10
→ x = -3 × 2
→ [ x = -6 ]
Hence, the value of x is -6.
The cost to rent a paddle boat at the county park is $8 per hour plus a nonrefundable deposit of $10. The cost can be modeled by the function f(h) = 8h + 10, where
h represents the number of hours the boat is rented. Describe the graph of g(h) as it relates
to f(h) if the nonrefundable deposit increases to $15.
When the non-refundable fee increases to $15, the y-intercept is also increased to 15. The graph are parallel to each other but only touches the y-axis at 10 and 15 respectively
Linear EquationLinear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.
Linear equations are generally represented in the form
y = mx + c
c = y-interceptm = slopeThe y-intercept is the point at which the graph touches the y - axis
In the question, we are given an equation f(h) = 8h + 10
The slope and y - intercept here are 8 and 10 respectively.
However, when the non-refundable deposit is increased to 15, the y - intercept is increase by 5 units to becomes 15.

What is the length of NM?
Answer:
See below :)
Step-by-step explanation:
We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3
[tex]\frac{6}{\sqrt3}[/tex]
We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3
[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]
This then makes it 6 times root 3 over 3
[tex]\frac{6\sqrt3}{3}[/tex]
We then get [tex]2\sqrt{3}[/tex]
Last question! Any explanation is appreciated, sorry for bad quality
Answer:
1/2
Step-by-step explanation:
When you have two points you need to use the slope formula:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_1}[/tex]
x1 and y1 is the first point and x2 and y2 is the second point, remember that the first number is X and the other is Y so...
[tex]m=\frac{5-4}{3-1} \\m=\frac{1}{2}[/tex]
1/2 is the slope of the points
Kerry has a collection of 1,100 baseball cards. Of these baseball cards, 40% are dated before 1970, 25% are dated from 1970 to 2000, and the rest are dated after 2000. How many baseball cards in Kerry’s collection are dated after 2000?
Answer:
385 cards
Step-by-step explanation:
First, find 40% and 25% of 1100.
2/5 * 1100
2200/5 = 440 cards dated before 1970
1/4 * 1100
1100/4 = 275 cards dated between 1970 and 2000
Then add the two amounts together.
440 + 275 = 715 cards between pre-1970 and 2000
After that, subtract your new sum from 1100.
1100 - 715 = 385 cards after 2000
(Or to make it easier, just find 35% of 1100.)
