Answer:
Multiply x by 4 and make x negative if it's positive or make x positive if it's negative.
Step-by-step explanation:
Multiplying x by a number greater than 1 will stretch the parabola.
Changing x from positive to negative and vice versa reflects the parabola over the x-axis.
Move all terms that dont contain y to the right side and solve and you get:
y=4x/3-7
Hope this helps
Answer:

Step-by-step explanation:
We are given;
A geometric sequence;
-2,10,-50
Required to determine the nth term
The nth term in a geometric sequence is given by the formula;

where
is the first term and r is the common ratio;
In this case;

r = 10 ÷ -2
= -5
Therefore;
To get the nth term in the given geometric sequence we use;

Thus, the nth term is 
Jason = J Bill = B Sharon = S
J = 5+B
B= 2×S
J= 5+ (2×S)
Reta a:

reta x:

Retas paralelas possuem coeficientes angulares iguais ⇒ mₐ=mₓ

(-4,-2)

∴
y=3/4x+1
