Answer:
(–∞, –3)
Step-by-step explanation:
The function 
is a quadratic function of order 2 and positive coefficient.
This is in the form of the function 
, but it is displaced 3 units to the left of the x axis and two units up in the y axis. type of functions are decreasing from -∞ to its vertex and then they are increasing from the vertex to infinity.
Observe in the attached graph that this function has its vertex in the point (-3, 2) and is decreasing from -∞ to x = -3. Then it is increasing until ∞. Therefore the correct option is:
(-∞, -3)
Answer choice A, it has a y-intercept of 3
Answer:
The price of one jar of dipping sauce is $2.98
Step-by-step explanation:
Let
x ----> the price of one bag of chip
y ----> the price of one jar of dipping sauce
we know that
<em>Corinne</em>
----> equation A
<em>Ginger</em>
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (1.98,2.98)
see the attached figure
therefore
The price of one bag of chip is $1.98
The price of one jar of dipping sauce is $2.98
Answer:
x = 8
Step-by-step explanation:
Δ TSU and Δ TRV are similar , thus the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
= 
( cross- multiply )
3x = x + 16 ( subtract x from both sides )
2x = 16 ( divide both sides by 2 )
x = 8
