Answer:
k = 20
May I have brainly? :D
Step-by-step explanation:
-16k + 7 = –15k − 13
+16k +16k
7 = 1k - 13
+13 +13

Step-by-step explanation:
Kiera and Hannah have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Kiera earns a base wage of $6 per hour, as well as $1 for every subscription that she sells. Hannah gets $2 per subscription sold, in addition to a base wage of $4 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How many subscriptions would that be? Write a system of equations, graph them, and type the solution
Answer:
Hannah sold 4
Kiera sold 6
Total Subscriptions = 10
Step-by-step explanation:
K = number of Kiera subscriptions
H = number of Hannah subscriptions
T = hours
6+K = 4+2H
K = 2H-2
K+H = 10
K= 10-H
substitute for K
2H-2 = 10-H
simplify
3H = 12
H = 4
K = 6
Can Someone help me to answer the question
Answer: X = -4
Step-by-step explanation:
90 - 5x + 62 -2x = 180
152 - 7x = 180
-7x = 28
x = -4
Check your answer by pluging in the vaule of x
90 - 5(-4)
90 + 20 = 110
62 - 2(-4)
62 + 8 = 70
110 + 70 = 180
Checks out.
Answer: 110 degrees and 70 degrees
Step-by-step explanation:
These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180
Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180
Subtract 152 from both sides of the equation.
-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70
We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180
The area of a parallelogram is 22 square inches. The height of the parallelogram is 11 inches. What is the length of the base?
Answer:
Base (x) = 2
Step-by-step explanation:
First we know that to find the area you do:
Area=Base x Height
So plug in the 22 as the area and the 11 as the height so it looks like this:
22 = (x) x 11
Then to find x all you have to do is divide 22 by 11 in order to get x by itself:
22/11 = x
So your answer is 2

What are the zeroes of f(x) = x2 + 5x + 6?
Answer:
The zeroes are: -3 and -2
Step-by-step explanation:
f(x) = x² + 5x + 6
This is the in the format...
ax² + bx + c
To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.
The two numbers are...
3 + 2 = 5 (This is correct because the two numbers add are equal to B)
3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)
You then know that you have ( x + 3 ) and ( x + 2 )
Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.
Here's what I mean by that...
x + 3 = 0
Subtract 3 on both sides...
x = -3
The other zero...
x + 2 = 0
Subtract 2 on both sides...
x = -2
Your answers are x = -2 and x = -3, make sure you always set your answers to zero.
Hope this helps!

How do I solve a Quadratic Equation using Completing the Square method
Please keep it short and brief like if you were explaining it to someone who just randomly came up to you and asked you irl
Answer:
Step 1 Divide all terms by a (the coefficient of x2).
Step 2 Move the number term (c/a) to the right side of the equation.
Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

Hello, So this is for school in general, I am in 7th grade and when i am given assignments i attempt to do them and i get confused, I try do them and i end up sticking with it. Then i don't pay attention and i get confused on current assignments then i get FARTHER behind and i get so far behind and pressured i shut down and give up, Any Suggestions to help because at 11:59 PM all assignments lock and 3rd marking period assignments will not be graded
Answer:
Try working in 15-30 minute periods and taking a 5 minute break between
don't stress about it because you can do this! just sit down in a quiet room and try your best your only in 7th grade so even if you don't get everything done it won't effect you moving forwards too much and try talking to someone about falling behind like a trusted adult or teacher they might be able to help you come up with a game plan for the future
Hope This Helps And I Wish You Luck!
Answer:
Hmm similarly my sister and I, who are both in school, have the same issue. Some tips that I use myself are, listening to music without words in the background. This helps me calm down and releases stresses, as well as calming scents if you have any like lavender. Try to stretch every so often, this helps gain energy and let blood flow through your veins to your brain. Try listing your assignments you need to get done for the week and when you get done with one, cross it out. This makes me feel so much more accomplished and then I can tackle the assingments I am behind on. Also drink LOTS of water! This helps your WHOLE body!
Remember that these don't work for everyone and if you need anything else I can try to give you some more help! Try not to stress too much, believe me that is definitely a lot easier said than done! As long as you try your best and work towards your goal, that's what matters. Life is about your journey, not your destination. Try to stay positive! Not everything is going to be easy, but you can do it!

9 cm and the other leg measures 11 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
14.2 cm
Step-by-step explanation:
The hypotenuse of a triangle is measured using the pythagorean theorem. This formula sums up the squares of both legs of the triangle which would give the squared value of the hypotenuse. Therefore, we can then square root that value to find the hypotenuse. This would be the following...
[tex]9^{2} + 11^{2} = x^{2}[/tex]
81 + 121 = [tex]x^{2}[/tex]
202 = [tex]x^{2}[/tex]
14.21 = [tex]x^{2}[/tex]
Finally, we can see that the value of the hypotenuse is 14.2 cm

Answer:
a) 11x^5
b) 4 1/2mn
Step-by-step explanation:
Según los subrayados de las preguntas, creo que solo necesita ayuda en a y b. (Disculpe también mi español, no es mi lengua materna.) Entonces, para el primero, ya que ambos tienen el mismo exponente, todo lo que necesita hacer es restar los números. Como resta un negativo, el resultado es positivo, lo que significa que en su lugar agrega el número (sin el negativo)
Para el segundo, debes restar la fracción del número entero. Esto entonces su ecuación es 5- 1/2 que es 4 1/2mn. Entonces tu respuesta es 4 1/2mn
F(x)=4x^2+4x-15 Write the function D in intercept form. Use this form to list the zeros of the function.
Answer:
Zeros are x = 1.5, -2.5
Step-by-step explanation:
Given function is,
F(x) = 4x² + 4x - 15
= 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]
F(x) = 4(x² + 2.5x - 1.5x - 3.75)
= 4[x(x + 2.5) - 1.5(x + 2.5)]
= 4(x - 1.5)(x + 2.5)
For 'x' intercepts,
f(x) = 0
4(x - 1.5)(x + 2.5) = 0
x = 1.5, -2.5
Therefore, zeros of the given function are x = 1.5, -2.5.
