So. We need to look at points. We know our X values, and our Y values. (X,Y)
(-4,-6) and (2,6)
The best way to approach this would be to graph the points that are given. You can use any app or graphing calculator you'd like.
So, for the first one, We need to find (-4) by going to the left, then proceeding to go down by (-6).
We then can proceed to do this for the other ones and calculate the slope intercept form in this way.
OR!
We can calculate it before hand by using the equation:
(Y2-Y1)÷(X2-X1)
Pick which equation will represent one, and which one will represent two.
I will choose (-4,-6) as Equation 1 and (2,6) as equation two.
We then plug it into the equation to look like:
(-6-6)÷(-4-2)
Your answer: -12/-6
Your slope is 2.
We then will graph it by placing it in slope intercept form.
Since we know our slope is two, We can go ahead and insert it. When the two points are finally graphed, We see they cross rhe Y-Axis at 2.
YOUR SLOPE INTERCEPT FORM IS:
Y=2x+2
Answer:
Step-by-step explanation:
We can use Hypotenuse Theorem for this:
For triangle ABC,
AC²=CB²+BA²
9²=CB²+3²
Switch the sides
-CB²=3² -9²
-CB²= 9-81
-CB²= -72
the signs cut each other
CB²=72
the square changes sides
CB=√72
CB= 8.49 cm
Now triangle CBD
We have the length of CB but not the other two whereas we have the angle
It will be sin
As we know sin= O/H
Here O is CB whereas H is CD
Put the values
sin 50= 8.49/H
H= 8.49 ÷sin 50
Calculate
H=11.1 cm
As we know H is CD so CD is 11.1 cm
Hope it helps
Answer:
I think its A.
Step-by-step explanation:
I think that it is A, 180..
Answer:
a= infinite
b= one sol
c= no solutions
d= infinite
Step-by-step explanation:
I how this helped. Basically solve for X and see if you can. If you can't it is zero solutions, if you can solve it one way then it is one solution, and if will will always solve then it is infinite solutions.
