4 0

Answer: About 10.5 passed.

Step-by-step explanation:

1. Convert 50% into a decimal.

  • First, convert 50% into a fraction, which is 1/2.

  • Divide 1/2 by its numerator and denominator.

  • 1 / 2 = 0.5

Hence, the answer is 0.5.

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please help me!!!
dusya [7]

Answer:

B

Step-by-step explanation:

The red graph is a horizontal translation of 5 units left followed by a reflection in the x- axis.

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

The black graph is shifted 5 units left, thus

f(x) → f(x + 5)

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Note that the y- coordinate of the image is the negative of the original

Note also that \frac{y}{-1} = - y, thus

\frac{y}{-1} = f(x + 5) → B

System of equations by substitution<br> how do this?<br> y= x+2<br> y= -4x+7
jekas [21]
Equations are given,
y= x+2
<span>
y= -4x+7

As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.

So let's equal them and solve it.

</span>x+2=-4x+7\\ \\ x+2+4x=7\\ \\ x+4x+2=7\\ \\ 5x+2=7\\ \\ 5x=7-2\\ \\ 5x=5\\ \\ x=\frac { 5 }{ 5 } \\ \\ x=1
<span>
Now we have x's value we will plug it in the first equation to find "y".

</span>x=1\\ \\ y=x+2\\ \\ y=1+2\\ \\ y=3
<span>
(1,3)</span>
