replace x and y by their value 1 and 3
3 = 4(1) - 1 = 4-1 = 3
2(1) + 3 = 2 + 3 = 5
correct
<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>2</u><u> </u><u>:</u>
y = 4x - 1
2x + y = 5
y = 4x - 1
y = -2x + 5
y - y = 4x - 1 - ( -2x + 5 )
0 = 4x - 1 + 2x - 5
6x - 6 = 0
6x = 6
x = 6/6 = 1
y = 4x - 1
y = 4(1) - 1
y = 3
correct
Answer:
whhhhhh
Step-by-step explanation:
it is number 2 because i took the test
Step-by-step explanation:
Step 1: 25*x-((1/125)^(4*x-5))=0
step 2: simplify 1/125
step 3: 25x-(1/125)(4x-5)=0
pls i need one more brainly
8 : 4
16 : 8
4 : 2
Simplest:
2 : 1
X^2 + 8x + 16 =
(x + 4)(x + 4) or (x + 4)^2
