Answer:
k = -7
Step-by-step explanation:
Let's put the side with the variables on the left.
-k+16-2k-9=28
Now we need to isolate the variable, which is k in this case.
>> Isolating the variable <<Step 1: Simplify as much as you can.-k+16-2k-9=28
-k-2k+16-9=28
-3k+7=28
Step 2: Subtract 6 from both sides(-3k+5) -7 = 28 -7
-3k = 21
Step 3: divide both sides by -3k = -21/3
That's your answer:
k = -7

Answer:
sry i thought i knew how to do it but I can't remember
Step-by-step explanation:
Answer:
(x + 5)² + 10
Step-by-step explanation:
Given
x² + 10x + 35
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 10x
x² + 2(5)x + 25 - 25 + 35
= (x + 5)² + 10

help plz I don't understand
Answer:
AB ≈ 9.11
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan44° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8.8}{AB}[/tex] ( multiply both sides by AB )
AB × tan44° = 8.8 ( divide both sides by tan44° )
AB = [tex]\frac{8.8}{tan44}[/tex] ≈ 9.11 ( to 3 sf )
what is the distance between point A and point B?
Answer: [tex]\sqrt{45}\\[/tex]
Step-by-step explanation:
Use Pythagorean Theorem-

36+9= c^2
c=[tex]\sqrt{45}\\[/tex]
Manchu has drawn a
rectangle with a base of
24 cm and an area of
336 cm². He cuts the
rectangle as shown to make two triangles.
What are the height and area of each
triangle?
Answer:
Height of each triangle: 14cm
Area of each triangle: 168cm²
Step-by-step explanation:
So we know that the base of the area is 24. Lets find the height.
336 ÷ 24 = 14
If he makes two triangles out of the rectangle that just means he cuts it in half.
To find the area of one triangle lets do:
336 ÷ 2 = 168
Let's double check our answer:
(14 × 24) ÷ 2 = 168

The product (-9 )x(-5) x(-6)x(-3) is positive whereas the product (-9)x(-5)x6 x(-3) is negative. Why?
Answer:
Answers below!
Step-by-step explanation:
-9 x -5 = 45
45 x - 6 = -270
-270 x -3 = 810
The answer is positive because a negative multiplied by a negative equals a positive number.
-9 x -5 = 45
45 x 6 = 270
270 x -3 = -810
This answer is negative because a negative multiplied by a positive equals a negative number.

What is the answer to |60| ____|-60|
Answer:
=
Step-by-step explanation:
Equal too, you are finding the absolute value of both of them which means getting rid of any signs that is attached to them. 60 = 60
Answer:
|60| = |-60|
Step-by-step explanation:
| | means absolute value
The absolute value of any number is that number but in its positive form
So the absolute value of 60 is 60
The absolute value of -60 is positive 60
60 is equal to 60 therefore |60| = |-60|

Answer:
c. 9, 1, 0, 1, 9; Graph A
Step-by-step explanation:
The given equation is presented as follows;
y = x²
The values of 'x' are -3, -1, 0, 1, 3
The range of the values of 'y' are; (-3)² = 9, (-1)² = 1, 0² = 0, 1² = 1, 3² = 9
9, 1, 0, 1, 9
The completed table is presented as follows;
[tex]\begin{array}{cc}x&y\\-3&9\\-1&1\\0&0\\1&1\\3&9\end{array}[/tex]
The values can be extended using the equation to include points, x = -2, y = (-2)² = 4, and x = 2, y = 2² = 4
To give a graph that passes through the point (-2, 4) and (2, 4)
Given that the coefficient of x² is positive, the graph opens up
Therefore, the graph that best represent the equation is c, 9, 1, 0, 1, 9; Graph A On the coordinate plane, a parabola opens up and goes through (-2, 4), has a vertex at (0, 0), and goes through (2, 4).

Of 500 new electronic products, 280 were intended for people over the age of 16, and 320 used a rechargeable battery. Of those products with a rechargeable battery, 150 were intended for those under the age of 16. What is the probability that a new electronic product is intended for someone over the age of 16 or uses a rechargeable battery?
choices:
430/500 = 0.86
450/500 = 0.9
110/500 = 0.22
280/500 = 0.56
Answer:
450/500 = 0.9sorry if it's wrong
Step-by-step explanation:
Answer:
D. 280/500 = 0.56
Step-by-step explanation:
280 are intended for people over 16 and 320 use a rechargeable battery.
320-150 = 170 (intended for those under the age of 16)
The answer would be D because you need to take the highest number of products (280) that would satisfy the requirements.
Mark invests $1500 in an account that pays 5.7% interest compounded continuously. Assuming no deposits or withdrawals are made, how much money will be in the account after 10 years?
Answer:
$2,611.21
Step-by-step explanation:
A = P(1 + r/n)^nt
A = 1500(1 + 0.057/1)¹⁰
A = 1500(1.057)¹⁰
A = 1500(1.740803988528..)
A = 2611.205982792..
A ≈ $2,611.21

Which best describes the relationship between the two triangles below?
Triangle M N L. Angle M is 51 degrees and angle L is 36 degrees. Triangle F H G. Angle F is 51 degrees and angle G is 36 degrees.
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the third angle is unknown.
Triangle M L N is similar to Triangle F G H because of the angle-angle criterion, Angle M is similar to angle F, Angle L is similar to angle G, and Angle N is similar to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the side lengths are unknown.
Answer:
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Step-by-step explanation:
Triangles are similar if all of the angles are congruent and corresponding to the other triangle and the sides are proportionate. It is important to note that if the angles are congruent then the sides must be proportionate; so, the side lengths are not necessary. Additionally, the third angle theorem states that if two known angles are congruent then the third angles must also be congruent. So, the two triangles must be similar because all of the angles are congruent to their corresponding angles.
