Answer:
P'(–3, -8), Q'(–6, 4), R'(1, -1).
Step-by-step explanation:
When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.
The rule is
(x,y) ⟶ (x,-y)
Thus,
P(-3,8) ⟶ P'(-3, -8)
Q(-6,-4) ⟶ Q'(-6, 4)
R(1,1) ⟶ R'(1, -1)
The coordinates of the image triangle are:
P'(–3, -8), Q'(–6, 4), R'(1, -1)
The diagram below shows your source and image triangles. The red and blue arrows show how the points moved during the reflection.
Step 1 add -3y to both sides
3x+3y+-3y=10+-3y
3x=-3y+10
Step 2 divide both sides by 3
3x/3= -3y+10/3
The answer is x= -y +10/3
5661
23.5% of 7400 = 1739
7400 - 1739 = 5661
Answer:
8/9 x 5
5 x 1/9 x 8
5 x 8 divided by 9
Step-by-step explanation:
5/9 = 0.5555*8 =4.444
8/9 = 0.8888*5 =4.444
5*1/9 = 0.5555*8 =4.444
5*8 = 40/9 =4.444
Ok so the answer is D because first I solved the equation because you can’t find which answer choice it is equivalent to if you didn’t solve it ... so I solved the equation and got x=-3/2 how I solved this is
3^-x = 3^3x+6 ... since the bases are the same, set the exponents equal
-x=3x+6..... move the variable to the left-hand side and change its side
-x-3x=6 ... collect like terms
-4x = 6..... divide both sides of the equation by -4 and I got x=-3/2
I don’t want this text to be that long so they both seem calculated the same way that’s why i got -3/2 hope that helps;-;
