Solve (x + 2 < 5) ∩ (x - 7 > -6).

garri49 [273]

Let $A=x+2\lt5, B=x-7\gt6$ .

Simplifying both you get $A=x\lt3,B=x\gt1$ .

The set conjunction is $A\cap B=1\lt x\lt3$ .

So the answer is B.

Hope this helps.

Please help <3 Find the value of the variables in the parallelograms.

Mashutka [201]

Answer:

Hello!

answer: a = 5

b = 8

Step-by-step explanation:

since we are given 1 side of the parellogram we can use that to figure out the rest! parellograms will add up to 360 degrees since 1 angle is 115 that means the other will be 115 115 + 115 = 230

360 - 230 = 130 since there 2 angles across from each other they will both equal the same so 130 ÷ 2 = 65 so both of these angles will have to equal 65 because 65 + 65 + 115 + 115 = 360 a = 5 because 14 x 5 = 70 and 70 - 5 = 65 b = 8 because 8 x 8 = 64 and 64 + 1 = 65 Hope this helps you understand!

Which is a y-intercept of the graphed function?

Pie

Answer:

Option C is correct.

The y-intercept of the graphed function is; $(0,- 9)$

Explanation:

To find the y-intercept of the graphed function:

The point where the graph crosses the y-axis is call y-intercept.

You can also find the y-intercept by looking at the given graph and seeing which point crosses the y-axis also this point will always have an x-coordinate of 0.

End behavior of a polynomial function is the behavior of the graph of function as x approaches $+\infty$ or $-\infty$
