Answer is HL
YZ = YZ
WY = XY
<X and <W is right angle
<span>if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent</span>
30+5y_>4x
5y_>4x-30
The answer is: y_>(4/5)x-6
You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.
"starts with 90 pencils" implies that the y-intercept is (0,90).
"gives away 15 pencils" implies a slope of -15 pencils per unit of time
Thus, the # of pencils Jabian still has is P(x) = 90 - (15 pencils / time unit)x
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.

7y+3=10y+9
-3 -3
7y=10y+6
-10y -10y
3y=6
Y=2
