Answer:
-1
Explanation:
Let the number be x.
Then the equation will be:
3(x+18) = 51
=> 3x + 54 = 51
=> 3x = 51 - 54
=> 3x = -3
=> x = -3/3
=> x = -1
So, the number you thought of is -1.
<em><u>Answer:</u></em>
12.8 or option 3
<em><u>Step-by-step explanation:</u></em>
So this is actually a proportion:
The large triangle to the smaller one:
<em>The angles of the triangles are the same so they are proportional</em>
We know the larger one is 20/8 times the smaller one's sides because
<em>YZ = something times QR so:</em>
20 = 8 times 20/8
In order to find PR, we have to divide ZX by the proportion rate thing so:
32 / (20/8)
= 32 * 8/20
= 64/5
= 12.8
the general equation of a circle is given by (x-a)^2+(y-b)^2=r^2
where (a,b) are the coordinates of the center.
from the given equation then (1,0) will be the center of the circle. and for the radius of the cirlce equate r^2 with 5...r^2=5 therfore r=
.
The graph will have a slope of 1 and a y-intercept of 3. That means it will cross the y-axis at 3, and will increase by 1 in the y direction for every increase by 1 in the x direction.
