8(10-k)-2k=0 just need help solving

Answer: 50 houses

Step-by-step explanation: If there was 100 houses the 60 percent would be 60 houses but all they did was cut the number of houses in half to try and trick you.

Answer:

Below in bold.

Step-by-step explanation:

f(x) = -x^2 + 10x - 17

Convert to vertex form by:

f(x) = -(x^2 - 10x) - 17

= - [(x - 5)^2 - 25] - 17

= -(x - 5)^2 + 25 - 17

=  -(x - 5)^2 + 8,

a. So axis of symmetry is x = 5.

b. Vertex is (5, 8) Max.

c.   Domain is All real x.

d. Range is (-∞, 8].

Answer:

D

Step-by-step explanation:

Ascending means they are moving upwards.

Answer:

0

Step-by-step explanation:

To solve this without L'Hopital's rule, you need to use this identity:

lim(x→0) (sin x / x) = 1

lim(x→0) (sin²x / x)

lim(x→0) (sin x / x) (sin x)

lim(x→0) (sin x / x) · lim(x→0) (sin x)

1 · 0

0

Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule.  Replace the numerator and denominator with their derivatives.

lim(x→0) (sin²x / x)

lim(x→0) (2 sin x cos x / 1)

0

Answer:

0

Step-by-step explanation:

according to what is given:

K = 0

N = 3

I = -2

so just substitute in these values into the given equations and solve

KN + IK

0 * 3 + -2 * 0

= 0 + 0

= 0

Answer:

C

Step-by-step explanation:

Both AB and AC have the length of 8, meaning that they're congruent.

This means that we have an isosceles triangle.

Angle B and Angle C are equal and all angles in a triangles add up to 180 degrees so:

30 + 30 = 60

180 - 60 = 120

So C would be your answer.

Please let me know if I'm incorrect :)

Answer:

120°

Step-by-step explanation:

This is an Isosceles triangle and that means angle C = angle B

Since the sum of interior angles in a triangle is equal to 180° the measure of angle A is = 120°

Answer:

Jesse will have $120.

Step-by-step explanation:

First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:

15x+60=?

Then you plug in the 4 lawns he did:

15(4)+60=

Then you solve and get 120! :)

PS Parenthesis mean you are multiplying. Same thing as saying

15 x 4 + 60= 120

Answer:

Step-by-step explanation: You must multuply the number of tacos by the money for all of them then you compare them and see if the see if they payed the same rate!P.S i'm in class too!!

Answer: They did not pay the same rate

Step-by-step explanation:

If they were to pay the same price the unit rate would be 1.25 but instead Ryan paid 1.25 for each taco and Maria paid 1.6 for each taco, which means they did not pay the same rate.

Answer:

1 mile: 4 minutes

Step-by-step explanation:

This problem can be expressed with a simple ratio: 2:8

Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.

This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.

Answer: y=-1/4x+3

Step-by-step explanation:

==================================================

Explanation:

y = mx+b is the general form of slope intercept equations

m is the slope, b is the y intercept

The y intercept is where the graph crosses the y axis. In this case it is at (0,3) so b = 3 is the y intercept

--------------------

The slope can be found through using the slope formula

m = (y2-y1)/(x2-x1)

m = (2-3)/(4-0)

m = -1/4

Or you could note that to go from (0,3) to (4,2) we must go down 1 and over to the right 4.

slope = -1/4 = rise/run

rise = -1 means we go down 1

run = 4 means we move to the right 4

--------------------

Since m = -1/4 and b = 3, we go from y = mx+b to y = (-1/4)x+3

Answer:

3 x3 x 3 x 5

Step-by-step explanation:

Answer:

135 is a composite number.

135 = 1 x 135, 3 x 45, 5 x 27, or 9 x 15.

Factors of 135: 1, 3, 5, 9, 15, 27, 45, 135.

Prime factorization: 135 = 3 x 3 x 3 x 5, which can also be written 135 = 3³ x 5

Answer:

no. 1

B. Describe the presicion of these results

no. 2

a. Describe the accuracy of these results

Answer:

1/4 is the answer for this because the slope is 1 and 4 so this means it is going up at a 1/4 slope.

Answer:

The slope = 1/4

Answer:

[tex]a_{n}[/tex] = 6n - 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

8 - 2 = 14 - 8 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 6 , thus

[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

Thus the formula representing the sequence is

[tex]a_{n}[/tex] = 6n - 4
