Jessica is doubling a recipe that calls for 1 1/2 cups of milk. How many cups of milk in total does she need?
2 x 1 1/2 = 3
She needs 3 cups of milk in total.
Answer:
Step-by-step explanation:
Given:
∠2 ≅ ∠7 ≅ ∠19
m∠2 = 125°
Since, m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 + 125° = 180°
m∠1 = 180 - 125 = 55°
m∠1 = m∠3 = 55° [Vertically opposite angles]
m∠2 = m∠4 = 125° [Vertically opposite angles]
m∠5 = m∠7 = 125°
m∠5 + m∠6 = 180° [Linear pair of angles]
125° + m∠6 = 180°
m∠6 = 180 - 125 = 55°
m∠7 = m∠5 = 125°
m∠8 = m∠6 = 55°
m∠19 = m∠17 = 125° [Vertically opposite angles]
m∠19 + m∠18 = 180° [linear pair of angles]
125° + m∠18 = 180°
m∠18 = 55°
m∠18 = m∠20 = 55° [Vertically opposite angles]
m∠13 = m∠20 = 55° [Corresponding angles]
m∠16 = m∠17 = 125° [Corresponding angles]
m∠15 = m∠18 = 55° [Corresponding angles]
m∠14 = m∠19 = 125° [Corresponding angles]
m∠13 + m∠10 + m∠8 = 180° [Sum of angles in a triangle]
55° + m∠10 + 55° = 180°
m∠10 = 180 - 110 = 70°
m∠10 = m∠12 = 70° [Vertically opposite angles]
m∠9 + m∠10 = 180° [Linear pair of angles]
m∠9 = 180 - 70 = 110°
m∠11 = m∠9 = 110° [Vertically opposite angles]

Answer:
Function 1: Not linear
Function 2: Linear
Function 3: Not linear
Function 4: Linear
Step-by-step explanation:
I used desmos then I input the given coordinates.
The answer to your question above, I will just illustrate it down.
<span>sqrt(3 x +7 ) = 1 - sqrt(x + 2 )
</span><span>square both sides:
3x + 7 = 1 -2sqrt(x = 2) + x + 2
Then it would become like this,
</span><span>2x + 4 = -2sqrt( x + 2 )
</span>Divide both sides by -2 to eliminate the -2 on the left side with sqrt.
Then <span>square both sides:
x^2 + 4x + 4 = x + 2
</span><span>x^2 + 3x + 2 = 0
</span><span>(x + 2) (x + 1) = 0
</span><span>x=-2, -1 there is no sqrt for-1
</span>so the answer is -2
