Answer: <em>уравнение имеет 2 решения:</em>
<em> x₁ = - 4; x₂ = - 2.</em>
Step-by-step explanation:
<em>Ix + 3I = 1</em>
<em>1) x + 3 = 1</em>
<em> x + 3 - 3 = 1 - 3</em>
<em> x = -2</em>
<em>2) - (x + 3) = 1</em>
<em> x + 3 = - 1</em>
<em> x + 3 - 3 = - 1 - 3</em>
<em> x = - 4</em>
Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1
9(10)-3(3)-1
90-9-1
80°
A
Because 0.8 is equaled to 8/10 which is greater than all
