Answer:
Step-by-step explanation:
Points are (1,9), (2,4), and (4,-30).
Subtract the first from the second.
-5 = 3a+b
Subtract 4 times the second from the third.
-34=12a+2b
-14=-2b
b=7
a=-4
c=6
The value of x will be -3.
The slope formula is y2-y1/x2-x1
In this case fill in using the two sets of numbers (x is still missing).
-6-1, which equals -7.
X-4, which you have to figure out mathematically.
Well in order to get a slope of 1 -7 has to be divided by itself, which is still -7.
What subtracted by 4 equals -7?
That would be -3.
Answer:
-4.2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The answer is B because 2 x -2 + 8 = 4 So it matches up in that equation so answer is b
Answer:
see the explanation
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
Corresponding sides are
XY and PD
YZ and DQ
XZ and PQ
so
Corresponding angles are
∠X and ∠P
∠Y and ∠D
∠Z and ∠Q
so
∠X ≅ ∠P
∠Y ≅ ∠D
∠Z ≅ ∠Q
