In short, a horizontal translation, means f("x + some number"),

now, that number is 2, and is to the left, so that means f(x + 2)

\bf \begin{cases}
f(x)=-4x+3\\
g(x)=f(x+2)
\end{cases}
\\\\\\
f(x+2)=-4(x+2)+3\implies f(x+2)=-4x-8+3
\\\\\\
f(x+2)=-4x-5\impliedby g(x)

Which function has the same y-intercept as the line graphed below?
KatRina [158]

Answer:

D. y + 4 = 2x  

Step-by-step explanation:

The graph has a y-intercept at (0, -4).

A. y=16 - 3x/4

if x = 0, y = 16. FALSE.

B. 24 + 3y = 6x

If x = 0, 24 + 3y =     0

                     3y = -24

                       y =    -8. FALSE.

C. 4y + x = 16

If x = 0, 4y = 16

              y =   4. FALSE.

D. y + 4 = 2x

If x = 0, y + 4 =  0

           y       = -4. TRUE.

y = 4 + 2x has the same y-intercept as the graphed line.

Teresas restraunt bill comes to $29.99 before tax. If the sales tax is 6.25% and she tips the waiter 20%. What is the total cost
alisha [4.7K]

Answer:

$37.86

Step-by-step explanation:

Multiply 29.99 by 0.0625 to get the sales tax

29.99x0.0625=1.87

Multiply 29.99 by 0.20 to get the tip

29.99x0.20=5.998

Round 5.998 to 6

Add 1.87 to 29.99

29.99+1.87=31.86

Add 6 to 31.86

31.86+6=37.86

Can you help me with this problem
snow_lady [41]
Since there are no actual values, I guess we just have to isolate the b.

2A=bh (multiply both sides by 2)
2A/h=b (divide by h)

hope this helps
