Answer:
x= -2/5 and x= 3
Step-by-step explanation:
Given equation is,
5x^2 - 13x - 6 = 0
Or, 5x^2 - 15x + 2x - 6 = 0 ( using middle term method)
Or, 5x( x- 3) + 2 (x-3) = 0
Or, (x-3) (5x+2) = 0
Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.
So, x= 3 or, 5x = -2
Or, x= -2/5
So, the answer is x= -2/5 and x= 3.
Answer:
x ≤ -7
Step-by-step explanation
<em>the steps to solve this are:</em>
1. Add 10 to both sides to get the x value and constant isolated on both sides.
-2x ≥ 14
2. Divide both sides by -2 to get the x value
x ≥ -7
3. Flip the inequality sign since you divided by a negative x-value.
x ≤ -7

Answer:
To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.
