Answer:
★ = 3
✚ = 4
■ = 4
◆ = 5
Step-by-step explanation:
If we use direct correspondence in the second equation, then we have ...
◆ = 5
★ = 3
The values of ★ and ✚ in the first equation must total 7. This means ...
✚ = 7 -3 = 4
Again, using direct correspondence in the third equation, we have ...
■ = 4
I am not able to graph but I will help you out. All you have to do to solve this is add the rule to the original x and y values. If the rule is (x+9, y-2) and the point is (-2,3) all we’d to do is plug it in.
-2+9=7
3-2=1
So the new point for P would be (7, 1)
If you need anyone help, lemme know. If you really can’t figure it out. I will grab my computer and graph it for you.
I hope this helps! It’s been a while since I’ve done slope-intercept though, so I might be a little rusty
Answer:
B
Step-by-step explanation:
The parallel line:
y = mx + c
y = 5/7x + 7
Gradient of parallel line = 5/7
y = mx + c
y = 5/7x + c
-2 = (5/7 x -5) + c
-2 = -25/7 + c
-2 + 25/7 = c
c = 11/7
y = 5/7x + 11/7
The perpendicular line
y = mx + c
y = 5/7x + c
m = 5/7
Gradient of perpendicular line = -1/(5/7) = -7/5
y = mx + c
y = -7/5x + c
-2 = (-7/5 x -5) + c
-2 = 7 + c
-2 - 7 = c
c = -9
y = -7/5x - 9
