1 answer:
Vesna [10]3 years ago
6 0

Answer:

x=11

Step-by-step explanation:

We know that angles on a straight line equal 180 degrees, so we know that 8x+10+7x+5 = 180.

Simplify

15x+15=180

Solve

<em>Take</em><em> </em><em>away</em><em> </em><em>1</em><em>5</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

15x = 165

<em>Divide </em><em>1</em><em>6</em><em>5</em><em> </em><em>by</em><em> </em><em>15</em>

x = 11

Write {4, 16, 36, 64, 100, 144} in set builder notation
docker41 [41]

Answer:

Here we are given with the numbers 4 16 36 64 100

So in these kind of questions we have to find what common pattern is prevailing so in this one:

Subtracting every no from it's succeeding no gives a difference and those respective differences are forming pattern as follows:

16–4=12

36–16=20

64–36=28

100–64=36

So we have a new series 12 20 28 36 in this Subtracting every no from it's succeeding no gives a difference of 8 now in the latter series continues with the same pattern of difference of 8 and the series proceeds with next numbers 44 52 60 now these no gets added in the first original series as described as follows :

100+44=144

144+52=196

196+60=256

So the next 3 numbers are 144,196,256

Use the four functions below for this question:
Darina [25.2K]
f (x ) = 2 x + 5
For g (x) we will solve the system:
- 1 =-2 m + b
+
-9 = 2 m + b
----------------------
-10 = 2 b,  b = -5
-9 = 2 m - 5
2 m = -4
m = -2
g ( x ) = - 2 x - 5
For h (X):
m = (-1-5 ) / ( 3-0 ) = -6/3 = -2
5 = 0 + b,   b = 5
h ( x) = - 2 x + 5.
Now we have 4 linear functions:
1 ) f ( x ) = 2 x + 5
The slope is m = 2, y - intercept: y = 5 , zero: x = -2.5 and the function increases ( m > 0 ).
2 ) g(x) = - 2 x - 5
The slope is m = - 2, y-intercept: y =-5 , zero: x = -2.5 and the function decreases ( m < 0 ).
3 ) h ( x ) = - 2 x + 5
The slope is m = - 2, y - intercept . y = 5, zero: x = 2.5 and the function decreases.
4 ) j (x) = 2 x + 5
The slope is m = 2, y -intercept: y = 5, zero: x = -2.5 and the function decreases.
The functions f( x ) and j ( x ) are parallel and also g( x ) and h ( x ). They have the same slope.  
The functions f ( x ) and j (x ) are increasing and h ( x ) and h ( x ) are decreasing.
