Answers:
<h2>A, C, & E</h2>
Step-by-step explanation:
To see which ordered pairs work in the inequality, substitute the ordered pairs in for the variables. If you get a true statement, this means the pair is a solution to the inequality.
A. 3, 18
-3x + y <u>></u> 7
-3(3) + 18 <u>></u> 7
-9 + 18 <u>></u> 7
9 <u>></u> 7 Correct :)
3, 18 is a solution to this inequality.
B. -2, -3
-3(-2) + -3 <u>></u> 7
6 + -3 <u>></u> 7
3 <u>></u> 7 Incorrect :(
-2, -3 is not a solution to this inequality.
C. -1, 8
-3(-1) + 8 <u>></u> 7
3 + 8 <u>></u> 7
11 <u>></u> 7 Correct :)
-1, 8 is a solution to this inequality
D. 1, 9
-3(1) + 9 <u>></u> 7
-3 + 9 <u>></u> 7
6 <u>></u> 7 Incorrect :(
1, 9 is not a solution to this inequality.
E. 0, 7
-3(0) + 7 <u>></u> 7
0 + 7 <u>></u> 7
7 <u>></u> 7 Correct :)
0, 7 is a solution to this inequality.
<em>PLEASE MARK BRAINLIEST</em>
To completely factor you must from the Greatest common factor
In this case it is 4z
So the complete factorization is
4z(4x + 5y)
The y intercept is always c (-5) and to the axis of symmetry u do -b/2a which is -1 and the vertex is (-1,10) because u pug in -1 into the equation. lmk if it’s right!
A geometric sequence is a sequence in which there is a common ratio between any two consecutive terms. In this case if X:Y:Z are in the ratio of 2:7:8 the multiplying by a constant k, we have X=2k, Y= 7k and Z=8k.
Then if X, Y-12, Z form a Geometric sequence, it means X/Y-12=Y-12/Z which is the same as 2k/7k-12=7k-12/8k if we cross multply, we get
16k²= 49k²-168k +144
33k²-168k+144 =0 solving for k
k = 4 or 1.091 if we take the whole number to find the values of X,Y and z,
X= 8, Y= 28 and Z=32
