17
Step-by-step explanation:
< ABD = <ABC + < CBD
Substitute in what we are given
87 = 9x-1 + 6x+58
Combine like terms
87 = 15x +57
Subtract 57 from each side
87-57 =15x +57-57
30 = 15x
Divide by 15
30/15 =15x/15
2=x
We want to find <ABC
<ABC = 9x-1
= 9*2-1
=18-1
=17
Answer:
The point after the reflection:
Step-by-step explanation:
-Statement: If you reflect the point across <u>x-axis</u> or the <u>y-axis</u>, then the and the of the point can change either positive, negative or the same, depending on where the point is located on a graph.
-So, if you reflect the point across <u>x-axis</u>, then the point after the reflection, would be :
The following point:
The point after the reflection:
Answer:
Step-by-step explanation:
In this case, the example is missing the negative sign.
This is an example of scientific notation, which is used to reduce a very large number into a short expression like: 0.000000005, which is reduced in the expression .
It's important to say that the negative sing in the exponent, indicates that all zeros that are being reduce, are placed at the right of the number. Also, to apply a correctly scientific notation, the number reduced should be between 0 and 10.
Answer:
Greatest possible number of solutions of these set of equations are 2
Step-by-step explanation:
We have been given two functions in the question.
x² + y² = 9
9x + 2y = 16
We know that the equation of circle is given by:
(x - h)² + (y - k)² = r²
However, if (h, k) is equals to (0, 0), the equation of circle becomes:
x² + y² = r²
Which is similar to the fist equation
x² + y² = 3²
Hence first equation is a circle.
As the second equation is a linear equation, it is simply a line.
We know that a line passing through the circle can intersect it at only 2 points.
Where points of intersection between both circle and line shows the solution.
So.
There are 2 possible solution to this set of equations
