Answer:

Quadratic

Step-by-step explanation:

The difference between each term in the sequence:

3,8,13,18

The difference between those are:

5,5,5,5

If you get the second difference as the same number, this shows that the sequence is quadratic!

Hope this helps!

Maths f(x) type of question please help
ExtremeBDS [4]

Since 1 < x < 5, adding each side by a, where a is negative, gives

a > ax > 5a

and adding b to each side gives

a + b > ax + b > 5a + b

or

5a + b < ax + b < a + b

Since 7 < f(x) < 23, it follows that

5a + b = 7

a + b = 23

Solve for a by eliminating b :

(5a + b) - (a + b) = 7 - 23

4a = -16

a = -4

Solve for b :

-4 + b = 23

b = 27

Answer:

15a⁴b²-20a³b³+30a²b⁴

Step-by-step explanation:

3a²-4ab+6b²

so for 5a²b²

(5a²b²)(3a²-4ab+6b²)

=15a⁴b²-20a³b³+30a²b⁴

Instructions:Select the correct answer from each drop-down menu.
scZoUnD [109]

Answer:

Part A: Option A

Part B: Option C

Step-by-step explanation:

Given two points (7, 5) and (21, 15)

we have to find the slope of the line passing through above two points.

The slope of line can be calculated as

slope=\frac{y_2-y_1}{x_2-x_1}

m=\frac{15-5}{21-7}=\frac{10}{14}=\frac{5}{7}

Option A is correct.  

Part B: Also given another line with a slope that is one-third that of the slope of above and passes through the origin and the point

we have to find the point.

slope=\frac{1}{3}\times \frac{5}{7}=\frac{5}{21}

The equation of line becomes

y-y'=m(x-x')

y-0=\frac{5}{21}(x-0)

21y=5x

The point which satisfies the above equation passes through the line.

(3,5):21(5)=5(3) Not satisfied

(3,7):21(7)=5(3)  Not satisfied

(21,5):21(5)=5(21)  Satisfied

(21,7):21(7)=2(21)  Not satisfied

Hence, the line passes through the point (21, 5)

Option C is correct.

I need to know how to do this.
dolphi86 [110]
All of them use Tons, pounds or ounces so you need the conversion factors which are these.

1 Ton = 2,000 lbs
1 lb = 16 oz

2.) 6T = 12,000 lbs (6 x 2,000)
3.) 18 lbs = 288 oz (16 x 18)
4.) 3,200 oz = 200 lbs (3,200/16)
5.) 12 T = 24,000 lbs(12x2,000)
6.) 9 lbs = 144 oz (16x9)
7.) 7 lbs = 112 oz(16x7)
8.) 100 lbs = 1,600 oz (16x100)
9.) 60,000 lbs = 30 T (60,000/2,000)
10.) 40 oz < 4 lbs (4x16)
11.) 80 oz = 5 lbs (5x16)
12.) 5,000 lbs < 5 T (5x2,000)
13.) 18,000 lbs = 9 T (9x2,000)
14.) 25 lbs > 350 oz (250x16)
15.) 27 oz < 2 lbs (16x2)
16.) 3 T = 6,000 lbs (3x2,000)
17.) First you need to know how many ounces 22 pounds is, so you multiply 16 by 22 to get 352 oz. Then subtract by 112 oz, she can add 240 more oz or 15 more lbs.
