Tisha and her academic team are working to go to state finals. they must have a certain number of points, t, to advance. they have had three local matches, a, b and c, and will attend a district match. district match points count for twice the number of points than local matches do. choose the equation that would tisha find how many points they need to earn in the district match, d, to advance.

d = t - a - b - c all over 2
d = t over 2 - a - b - c
d = t + a + b + c all over 2
d = 2(t − a − b − c)

T - a - b - c all over 2

Step-by-step explanation:

Option 1 -

Step-by-step explanation:

Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance.

Tisha and her academic team have had three local matches a,b and c.

So, the point they need to earn is d=T-a-b-c

District match points count for twice times the number of points than local matches do.

So, the point in district mach is 2d.

The equation that would help Tisha is

Therefore, option 1 is correct.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
