X and y will be both 5.
please correct me if i am wrong.
Answer: D
Step-by-step explanation:
Ten thousandths is the fourth place
<u>Answer:</u>
<h2>E. (7, 5)</h2>
<u>Explanation:</u>
vertices C and D have the same coordinate x and x of D = 7
hence
x of C = 7
vertices A and D have the same coordinate y and y of D = 2
hence
m = 2
and
m+3 = 2+3 = 5
and since vertices B and C have the same coordinate y and y of B = 5
hence
y of C = 5
thus
coordinates x, y of C: (7, 5)
3x + 2y = 7
y = -3x + 11
Solve the system of equation using substitution.
Substitute the y in the first equation by its value presented in the 2nd equation.
3x + 2y = 7
3x + 2(-3x + 11) = 7
3x - 6x + 22 = 7
-3x + 22 = 7
-3x = 7 - 22
-3x = -15
-3x/-3 = -15/-3
x = 5
Substitute x in the 2nd equation by its computed value. x = 5
y = -3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 ; y = -4
Substitute x and y in the 1st equation with its corresponding values
3x + 2y = 7
3(5) + 2(-4) = 7
15 - 8 = 7
7 = 7
2×2=4 ( for one face)
so there r 6 faces = 6×4=24 square inches
