Two triangles are similar if and only if all corresponding angles are equal (congruence), even if the corresponding sides are equal or not, therefore the answer is true because ΔJKL and ΔRST are similar and the statement above demands that "it must be", namely, this is a sufficient condition.

Answer:
-3
Step-by-step explanation:
It would just be -12+9=-3.
The required x and y-intercept of the given line is -3 and -6/5 respectively.
<h3>What is the slope of the line?</h3>
The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The given equation of the line is 2x+5y=-6.
Transform into standard form of line .i.e is y = mx + c
5y = -2x - 6
y = -2x/5 - 6/5
here , m = -2/5 and c = -6/5
Since c = y-intercept of the line = -6/5
Now, put y = 0 in the equation of the line.
2x = -6
x = -3
Thus, the required x and y-intercept of the given line is -3 and -6/5 respectively.

Answer:
8 + 2x = 30
Step-by-step explanation:
Given,
The initial number of push-ups he does in each day = 8,
And, the number of push-ups, he increases per day = 2,
Let x be the number of days after he will reach his target of 30 push-ups,
Since, the number of push-ups she will increase in x days = 2x,
Thus, the number of push-ups she will do after x days = 8 + 2x,
⇒ 8 + 2x = 30, which is the required equation.
