Multiply 2nd equqation by -1 and add to first
5x+4y=22
<u>-3x-4y=-10 +</u>
2x+0y=12
2x=12
divide by 2
x=6
sub back
3x+4y=10
3(6)+4y=10
18+4y=10
minus 18 both sides
4y=-8
divide by 4
y=-2
(x,y)
(6,-2) is solution
Donte did a mistake that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.
<h3>What is a complex number?</h3>
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have an expression:
= 4(1 + 3i) – (8 – 5i)
= 4 + 12i - 8 + 5i
He did not distribute the subtraction sign correctly for 8 – 5i.
= -4 + 17i
Thus, Donte did a mistake in that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.

Answer:
Any from 1:3.5 , 4:14 , 6:21 (etc) would be equal to 2:7
Step-by-step explanation:
2 divided by 2 would be 1, and 7 divided by 2 would be 3.5. 2 times 2 = 4, and 7 times 2 = 14. 2 x 3 = 6, 7 x 3 = 21 (etc).
I think u have to do 120÷20=60
then 60×15=900
so he sold 900 flowers I'm not sure tho
Answer:
-6, -5, -4, -3, and -2
n≥-6
Step-by-step explanation:
Multiply both sides by 2
n≥-6
so the values that make this true are -6, -5, -4, -3, and -2
