Answer:
x>48/5 or x<-3/2
Step-by-step explanation:
<u><em>Solve for x</em></u>
<u>a) 12x + 7 < -11</u>
12x < -11-7
12x < -18
x < -18/12
<em>⇒ Simplify: divide the numerator by 6</em>
x < -3/2
<u>b) 5x – 8 > 40</u>
5x > 40+8
5x > 48
x > 48/5
Therefore, x>48/5 or x<-3/2.
Answer:
5x-5=3x +17 So were solving for x The answer would be =11
Step-by-step explanation:
You have to do 112 divided by 13 which will give you the answer
Answer:8.615
Answer:
; minimum
Step-by-step explanation:
Given:
The function is,
The given function represent a parabola and can be expressed in vertex form as:
The vertex form of a parabola is , where, is the vertex.
So, the vertex is .
In order to graph the given parabola, we find some points on it.
Let
So, the points are .
Mark these points on the graph and join them using a smooth curve.
The graph is shown below.
From the graph, we conclude that at the vertex , it is minimum.
Answer:
Step-by-step explanation:
-x + 5y - 7 = 0
-x + 5y = 7 --------------------(I)
4y - 10 = 5x
-10 = 5x - 4y
5x - 4y = -10 -----------------------(II)
-x + 5y = 7 --------------------(I)
5x - 4y = -10 -----------------------(II)
Multiply equation (I) by 5.
(I)*5 -5x + 25y = 35
(II) <u>5x - 4y = -10</u> {Now add and x will be eliminates}
21y = 25
y = 25/21
Substitute y value in Equation (I)
-x + 5*25/21 = 7
-x + 125/21 = 7
-x = 7 - (125/21)
-x = (147/21) - (125/21)
-x = (147-125)/21
-x = 22/21
x = -22/21
