B = -

C = \

Step-by-step explanation:

A has a positive slope because it is increasing its height

B has a slope of 0 because it doesn’t change height

C has a negative slope because it is decreasing its height

Use algebra to find the point at which the line h(x)=−(3/5)x+(7/5) intersects the line k(x)=(−8/3)x+(404/45).

Inga [223]

Answer: the point (3.667, 0.8)

Step-by-step explanation:

We want to find the point at which the lines:

h(x) = -(3/5)*x + (7/5)

and

k(x) = (-8/3)*x + (404/45)

If the lines intersect, then we must have:

h(x) = k(x)

if we write the functions we get:

-(3/5)*x + (7/5) = (-8/3)*x + (404/45)

Now we need to solve this for x.

-(3/5)*x + (8/3)*x = (404/45) - (7/5)

(8/3 - 3/5)*x = 404/45 - 63/45 = 341/45

(40/15 - 9/15)*x = 341/45

(31/15)*x = 341/45

x = (341/45)*(15/31) = 3.667

Now we can input this value of x in the functions to get the output.

h(3.667) = -(3/5)*3.667 + 7/5 = -0.8

Then the point where our points intersect is the point (3.667, 0.8)

Point L is located at (-3,-6) where is L after a reflection over the y-axis

ohaa [14]

9514 1404 393

Answer:

L'(3, -6)

Step-by-step explanation:

The reflection over the y-axis is modeled by the transformation ...

(x, y) ⇒ (-x, y)

L(-3, -6) ⇒ L'(3, -6)

Point L is located at (3, -6) after the reflection from the 3rd quadrant to the 4th quadrant across the y-axis.

What number is 53% of 470

Kazeer [188]

The word "of" is the same thing as a multiplication sign!

So instead see it this way:

53% × 470

To solve this, you can use the cross product method :

$\frac{53}{100}$ = $\frac{?}{470}$

(470 × 63) ÷ 100 = ?

29 610 ÷ 100 = ?

296.1 = ?

53% of 470 is 296.1

There you go! I really hope this helped, if there's anything just let me know! :)
