Answer:
m∠QRT = 90°
m∠QRT = m∠SRT
Step-by-step explanation:
Triangle QST is isosceles with QT ≅ ST. In isoscels triangle QST, angles STR and RTQ are congruent.
RT is angle T bisector, so angles QTR and STR are congruent.
Consider two triangles QTR and STR. In these triangles:
- TR ≅ TR (reflexive property);
- ∠QTR ≅ ∠STR (given);
- QT ≅ ST (given).
By SAS postulate, these two triangles are congruent. Two congruent triangles have congruent corresponding sides, so
Angles QRT and SRT are supplementary (add up to 180°). Since these two angles are congruent, they have the same measure equal to 
So, true options are
m∠QRT = 90°
m∠QRT = m∠SRT
Answer:
-1
Step-by-step explanation:
1.25(x+1.5)=0.625
(x+1.5)=0.5
x=-1
Answer:
8$ per hour
Step-by-step explanation
First, we need to find how many hours Naomi worked, total.
Simply add 
Now we know that Naomi earned 54$ over 6.75 hours.
All we have to do to find the hourly rate is divide 
Naomi earns 8$ per hour mowing lawns.
Answer:
Step-by-step explanation:
For a function given as,
f(x)= 2x + 2
Domain of the given function is → {-5, -1, 2, 3}
For the Range of the given function,
f(-5) = 2(-5) + 2
= -8
f(-1) = 2(-1) + 2
= -2 + 2
= 0
f(2) = 2(2) + 2
= 6
f(3) = 2(3) + 2
= 8
Therefore, set for the range will be → {-8, 0, 6, 8}
Now plot the ordered pairs on the graph,
(-5, -8), (-1, 0), (2, 6), (3, 8)
