11.2, 12.5, 12.5, 13.23, 13.23, 14.5, 15.6, 15.75
It's 13.23
No Because it is less than -30
Answer:
The value of x is -6
Step-by-step explanation:
Let us equate the fraction by its equivalent
∵
= -22
→ Multiply both sides by (x - 10) to cancel the denominator of the left side
∴
× (x - 10) = -22 × (x - 10)
∴ 352 = -22(x - 10)
→ Simplify the right side by multiplying -22 by the bracket (x - 10)
∵ 352 = -22(x) - 22(-10)
∴ 352 = -22x + 220
→ Add 22x to both sides
∵ 22x + 352 = -22x + 22x + 220
∴ 22x + 352 = 220
→ Subtract 352 from both sides
∴ 22x + 352 - 352 = 220 - 352
∴ 22x = - 132
→ Divide both sides by 22 to find x
∴ 
∴ x = -6
∴ The value of x is -6
Assume the sum is 100. The ratio of the two numbers is 15:10. This means that we can divide this indow 15+10, or 25 parts. Let us do that. Divide 100 into 25 parts and see how much is in each part. 100/25 is 4, meaning that there is 4 in each part. 15 parts will have 15*4, or 60. 10 parts will have 10*4, or 40. To confirm, add 40 and 60. It matches with what we started out with, 100.
The two numbers, assuming the sum is 100, are 40 and 60. 60 is the greater value.
The turning point is known as the vertex when we talk about parabolas. The vertex is either the highest point or the lowest point. In this case, it is the lowest point.
<h3>The graph shows the turning point at (-2, -1)</h3>
-------------------------------------------------------------------------------------------
The term "root" is another term for "x intercept". This is where the graph crosses or touches the x axis.
<h3>The two roots are (-3, 0) and (-1, 0)</h3>
Since the y coordinate of any x intercept is always y = 0, we can state "the roots are -3 and -1" to indicate what is in bold above, just in a shortened way.
Side note: the x coordinate of the vertex is always halfway between the x coordinates of both roots of any parabola. The vertical axis of symmetry passes through the vertex.
