If h(x)= -kx + 14 and h(2)=18, find the value of k

k = - 2

evaluate h(2), equate to 18 and solve for k

h(2) = - 2k + 14 = 18 ( subtract 14 from both sides )

- 2k = 4 ( divide both sides by - 2 )

k = - 2

h(x)= -kx + 14

18 = -k*2 + 14   since x=2

18 = -2k +14

subtract 14 from each side

4 = -2k

divide by -2

-2 =k

Hanks pickup can travel 85 miles on 5 gallons of gas. How many gallons will his pickup need to travel 34 miles?
tankabanditka [31]

Hank will need 2 gallons of gas. 85/5 is 17, so Hank can go 17 miles on 1 gallon of gas. 17•2= 34, to go 34 miles you will need 2 gallons of gas.

Can anyone help me with this question please?
Oxana [17]

Answer:

y=35z+20

Step-by-step explanation:

Y is the total cost, so it goes on the outside. 35z represents the months of service because you multiply 35 by however many months there are (for example, if you had 3 months, you'd have $35 3 times). Finally, the $20 is tacked onto the end because that's the initial payment to open an account

If x-3 is a factor of x3+4x2+kx-30.Find the value of k.​
Bogdan [553]

Answer:

k=-11

Step-by-step explanation:

x^{3}+4x^{2}+kx-30

if x-3 is a factor,

(3)^{3}+4(3)^{2}+k(3)-30=0\\27+4*9+3k-30=0\\27+36+3k-30=0\\33+3k=0\\3k=-33\\k=-11

Which of these is a parent function? And can you tell me how you know?
avanturin [10]
Hey there!

A parent function is the most basic function in any group of functions. For example, f(x) = x^2 is the parent function for quadratic functions, and y = x is the parent function for linear functions. When there's nothing added, subtracted, multiplied, or divided to the function.

For A, we see that we're multiplying 2 times 3^x, and since this is not any alternation of any parent function or any parent function in particular, we can rule it out.

For B, we see that 3 is being added to x^2, so it cannot be a parent function.

For C, we see that 2 multiplied to e, therefore it cannot be the mot basic function.

Finally, for D, we see a function that looks similar to the quadratic parent function and is very simple itself. Any alterations to this is any other quadratic function

Your answer is D.

Hope this helps!
