Given f(x) = (x - 4)^2 - 1, what is the change made to g(x) if the parent function is f(x) = x^2?

1.
g(x)=(x-4)^2-1

f(x) was moved 4 units right and 1 unit down

2.
f(x)=x^2\\
g(x) = x^2 + 3

f(x) was moved 3 units up

3.
f(x)=x^2\\
g(x)=\dfrac{1}{4}(x-6)^2+8

f(x) was moved 6 units right, scaled down along the y-axis 4 times and moved 8 unit up

4.
f(x)=x^2\\
g(x)=-(x-3)^2+2

f(x) is moved 3 units right, reflected over the x-axis and moved 2 units up

Aaron and Maria collected shells one morning at the beach. Maria had 3 times as many as Aaron, but they would have had the same
Hoochie [10]
Let the amount of shells collected by Aaron be x and the amount of shells collected by Maria be y respectively. Then the following system of equations should be solved:
\left \{ {{3x=y} \atop {x+8=y-6}} \right.

First of all, express y out of first equation:
y=3x

Then, replace y in second equation with found expression and solve it:
x+8=3x-6
2x=14
x=14/2=7

Finally, replace x in first equation with found value and solve it too:
3*7=y
y=21

So, Aaron has found 7 shells while Maria has found 21.

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered
Leona [35]

(i) Pairs of <em>neighboring</em> angles are <em>supplementary</em> and <em>opposite</em> angles have the <em>same</em> measure.

(ii) The two angles formed by a line coming out of another line are <em>supplementary</em>.

<h3>How to analyze pairs of angles</h3>

(i) When two <em>straight</em> lines pass through each other, then <em>two</em> pairs of <em>opposite</em> angles are constructed. A pair with angles of (3\cdot x + 52)^{\circ} and another pair with angles of (2\cdot x + 2)^{\circ}, each pair of angles with <em>different </em>measures are <em>supplementary</em>.\blacksquare

(ii) When a <em>straight</em> line comes out of another <em>straight</em> line, from a point distinct to any endpoint of the former, then we construct two <em>supplementary</em> angles. The <em>largest</em> angle has a value of (10\cdot x + 20)^{\circ}, whereas the <em>smaller</em> one has a value of (6\cdot x + 8)^{\circ}. \blacksquare

Heidi's friends want to reserve a karaoke studio this weekend. It cost $30 to reserve a room, plus $5 per person for pizza, plus
Ksenya-84 [330]

Answer:

5

Step-by-step explanation

2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65

what do i mean?

2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people

4. What is the system of equations that describes the following graph?
GarryVolchara [31]

Answer:

The system of inequalities is

y

y>0.25x

Step-by-step explanation:

step 1

Find the equation of the dashed line with negative slope

The line passes through the points

(0,-2) and (-2,0)

Find the slope

m=(0+2)/(-2-0)=-1

Find the equation of the line in slope intercept form

y=mx+b

we have

m=-1\\b=-2

substitute

y=-x-2

The solution of the inequality is the shaded area below the dashed line

therefore

The equation of the inequality A is

y

step 2

Find the equation of the dashed line with positive slope

The line passes through the points

(0,0) and (4,1)

Find the slope

m=(1-0)/(4-0)=0.25

Find the equation of the line (direct variation)

y=kx

we have

k=0.25

substitute

y=0.25x

The solution of the inequality is the shaded area above the dashed line

therefore

The equation of the inequality B is

y>0.25x

therefore

The system of inequalities is

y

y>0.25x
