The black graph is the graph of y=f(x). Choose the equation for the red graph. Please help me!!!

dusya [7]

Answer:

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

What is the slope–intercept form of the equation 4x − 2y = 9?

adelina 88 [10]

Hey there! :D

Slope intercept form: y=mx+b

4x-2y=9

Add 2y to the other side.

4x=9+2y

Subtract 9 on both sides.

4x-9=2y

Flip the equation over.

2y=4x-9 <== slope intercept form

I hope this helps!

Evaluate each expression. Determine if the final simplified form of the expression is positive or negative -42 (-4)2 42

Sati [7]

Answer:

Given the expression:

$-4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$-4^2 = -16$

Therefore, the value of expression $-4^2$ is -16 i.e negative.

$(-4)^2$

we know:

$4^2 = 4 \times 4 = 16$

$(-1)^2 = 1$

then;

$(-4)^2 = (-1)^2 \cdot (4)^2= 16$

Therefore, the expression $(-4)^2$ is 16 i.e Positive.

$4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$4^2 = 16$

Therefore, the expression $4^2$ is 16 i.e Positive.

In a group of a hundred and fifty students attending a youth workshop in mombasa, 125 of them are fluent in kiswahili, 135 in en

jek_recluse [69]

Answer:

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = 1.1

Step-by-step explanation:

Step(i):-

Given total number of students n(T) = 150

Given 125 of them are fluent in Swahili

Let 'S' be the event of fluent in Swahili language

n(S) = 125

The probability that the fluent in Swahili language

$P(S) = \frac{n(S)}{n(T)} = \frac{125}{150} = 0.8333$

Let 'E' be the event of fluent in English language

n(E) = 135

The probability that the fluent in English language

$P(E) = \frac{n(E)}{n(T)} = \frac{135}{150} = 0.9$

n(E∩S) = 95

The probability that the fluent in English and Swahili

$P(SnE) = \frac{n(SnE)}{n(T)} = \frac{95}{150} = 0.633$

Step(ii):-

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = P(S) + P(E) - P(S∩E)

= 0.833+0.9-0.633

= 1.1

Final answer:-

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = 1.1
