Which statement is true regarding the graphed functions?

Novosadov [1.4K]

I’m not exactly sure but maybe f(0) = 4 and g(–2) = 4

Suppose that f(x)=x^2 and g(x)=-1/4(x+7)^2. Which statement best compares the graph of g(x) with the graph of f(x)?

wolverine [178]

Answer:

Both of these graphs are quadratics. They both form a parabola opening up

Step-by-step explanation:

The only difference between g(x) and f(x) is that g(x) is moved to the left 7 unit and has a horizontal stretch of 1/4

Rachel hikes at a steady rate from a ranger station to a campground that is 20 mi away. After 2 h, she is 13 mi from the campgro

Angelina_Jolie [31]

Answer:

-3.5

The distance Rachel covers per hour is 3.5 miles

Step-by-step explanation:

After 2 hours, she is 13 miles from the campground.

After 4 hours, she is 6 miles from the campground.

Let x be the number of hours, y be the number of miles from the campground, then we have two points (2,13) and (4,6).

The equation of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute:

$x_1=2\\ \\y_1=13\\ \\x_2=4\\ \\y_2=6$

Hence,

$y-13=\dfrac{6-13}{4-2}(x-2)\\ \\y-13=-3.5(x-2)\\ \\y=-3.5x+7+13\\ \\y=-3.5x+20$

The slope of the line is $-3.5$ and it represents that the distance Rachel covers per hour is 3.5 miles.

Please answer properly.

madreJ [45]

Answer:

$1) y=-6$

$2)x=3$

$3) y=8$

$4)a=8$

Step-by-step explanation:

$4y+24=0$

subtract 24 from both sides

$4y=-24$

divide both sides by 4

$y=-6$

---------->>>>

$15+3=6x$

combine like terms

$18=6x$

divide both sides by 6

$3=x$

---------->>>>

$9y-72=0$

add 72 to both sides

$9y+72$

divide both sides by 9

$y=8$

---------->>>>

$8a=75-11$

combine like terms

$8a=64$

divide both sides by 8

$a=8$

--------------------------------------------

Hope this is helpful.
