I don’t know whether I should shade above or below the line. PLEASE HELP I HAVE A TEST TOMORROW
lbvjy [14]

Answer:

I believe that you would shade the one in the bottom right corner, but you might want to double check

Step-by-step explanation:

you take a (x,y) coordinate from each quadrant and plug in the numbers to see if the equation is correct. If it isn't, you do not shade that quadrant.

so for example, y<1/2 x

say your coordinate is (2,1)

you plug in the numbers so that it looks like 1>1/2×2.

1/2 × 2 is 1,

so therefore this equation is incorrect because 1 is not greater than one.

Answer:

f(x) = 2x+5

Step-by-step explanation:

Given the arithmetic sequence shown

7,9, 11, 13, 15, 17,

THe nth term of the sequence is expressed as;

Tn = a + (n-1)d

a is the first term = 7

d is the common difference = 9-7 = 11-9 = 2

Substitute

Tn = 7 + (n -1)*2

Tn = 7 + 2n - 2

Tn = 2n + 5

Hence the required function is f(x) = 2x+5

Which of the following is equivalent to the expression below for x≠6?
nata0808 [166]

Answer:

The fourth answer choice is the correct one:  2(x - 3)

Step-by-step explanation:

2x²-18x+36/x-6 should be factored, as follows:

2(x²-9x+18) / (x-6) = 2(x - 3) (x - 6) / (x - 6)

Substituting x = 6 would result in division by zero and is thus not allowed.

Remembering this, we can reduce 2(x - 3) (x - 6) / (x - 6) to 2(x - 3) for x≠6.

Please help me for the brainliest answer
7nadin3 [17]
The answer is 928cm. There are 5 sides. When you find the area of a triangle you multiply base times height then divide by two. But in this case there are two identical triangles so you don’t need to divide. 24x12=288. Then you find the area of the long sides. Multiple 25 and 10 and you get 250. There are two of those sides. Now the last thing to do is find the area of the bottom side. For that one you multiply 14 and 10 and get 140. Now you add all of that together and get 928cm.

All the angles inside a triangle add up to 180°.

(2x + 15) + (5x + 5) + x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
the question is asking what angle B is,
B = 2(20) + 15
B = 40 + 15
B = 55°
