Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
given y = 5x - 3 with m = 5 and (a, b) = (- 2, - 13), then
y +13 = 5(x + 2) ← in point- slope form
<h3>Option B</h3><h3>Multiply first equation by -2 and second equation by 3, solution (1, 1)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
3x - 5y = -2 -------- eqn 1
2x + y = 3 ------- eqn 2
We have to solve the system of equations
Multiply eqn 1 by -2
-6x + 10y = 4 ------- eqn 3
Multiply eqn 2 by 3
6x + 3y = 9 -------- eqn 4
Add eqn 3 and eqn 4
-6x + 10y = 4
6x + 3y = 9
( + ) ------------
13y = 13
y = 1
Substitute y = 1 in eqn 2
2x + 1 = 3
2x = 2
x = 1
Thus solution is (1, 1)
Thus option B is correct
Use Pythagoras to find opposite side (length of wall
then divide this number by 10
Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12
-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4
Or whatever this other I’ve is called
-3x-9y=36
-1(X-9y)=(12)-1
-3x-9y=36
-x+9y=-12
-4x=24
X= -6
When a quadrilateral is inscribed in a circle, the sum of opposite angles is 180 degrees.
A+C=180
95+C=180
C=180-95
C=85
Therefore the answer is B). I hope this helped.
