Answer:
The y-intercept would be 7
The slope would be -1 or -1/1. They are both the same thing.
The slope is the number which is located directly to the left of the variable (the variable in this case is x, but in other situations it could be a totally different letter).
Answer:
Option A
Triangles ABC and TUV
Step-by-step explanation:
Given three triangles ABC , FGH and TUV
For triangles ABC and FGH, given that
DF =AB
DH = AC
and angle F = angle A
This cannot be taken as SAS congruence because the angle F is not included between the equal sides. Two triangles can be congruent by SAS only if two sides and included angle are congruent.
For triangles ABC and TUV we have AB=TU, AC = TV and
included angles between these sides are equal.
So these two triangles are congruent
We write corresponding sides only in order Hence ABC = TUV
and Not VTU =ABC
So option A is true.
Answer:
x = -7
, y = -5
Step-by-step explanation:
Solve the following system:
{3 y - 3 x = 6 | (equation 1)
3 x + 5 y = -46 | (equation 2)
Add equation 1 to equation 2:
{-(3 x) + 3 y = 6 | (equation 1)
0 x+8 y = -40 | (equation 2)
Divide equation 1 by 3:
{-x + y = 2 | (equation 1)
0 x+8 y = -40 | (equation 2)
Divide equation 2 by 8:
{-x + y = 2 | (equation 1)
0 x+y = -5 | (equation 2)
Subtract equation 2 from equation 1:
{-x+0 y = 7 | (equation 1)
0 x+y = -5 | (equation 2)
Multiply equation 1 by -1:
{x+0 y = -7 | (equation 1)
0 x+y = -5 | (equation 2)
Collect results:
Answer: {x = -7
, y = -5
Answer:
5 friends
Step-by-step explanation:
Since the snacks are worth $25, it is deducted from the total
10x=75-25
10x=50
x=5
