To make 3 cakes,we multiply the flour needed by three,and here's the equation:
2 \frac{1}{2}  \times 3 \\  =  \frac{5}{2}  \times 3 \\  =  \frac{15}{2}  \\  = 7 \frac{1}{2}
Thus, she'll need 7 and 1/2 cups of flour.

hope it helps!

Domain:\\\\3+2x\neq0\to x\neq-1.5\\\\\dfrac{6x-4}{3+2x}=\dfrac{5}{6}\qquad\text{cross multiply}\\\\6(6x-4)=5(3+2x)\qquad\text{use distributive property}\\\\(6)(6x)+(6)(-4)=(5)(3)+(5)(2x)\\\\36x-24=15+10x\qquad\text{add 24 to both sides}\\\\36x=39+10x\qquad\text{subtract 10x from both sides}\\\\26x=39\qquad\text{divide both sides by 26}\\\\x=\dfrac{39}{26}\\\\x=\dfrac{39:13}{26:13}\\\\\boxed{x=\dfrac{3}{2}}\in D

A student says that the graph of the equation y = 3(x + 8) is the same as the graph of y = 3x, only translated upwards by 8 unit
Wittaler [7]

Given:

A student says that the graph of the equation y = 3(x + 8) is the same as the graph of y = 3x, only translated upwards by 8 units.

To find:

Whether the student is correct or not.

Solution:

Initial equation is

y=3x

f(x)=3x

Equation of after transformation is

y=3(x+8)

g(x)=3(x+8)

Now,

g(x)=f(x+8)      ...(i)

The translation is defined as

g(x)=f(x+a)+b        ...(ii)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (i) and (ii), we get

a=8\text{ and }b=0

Therefore, the graph of y=3x translated left by 8 units. Hence, the student is wrong.
