Triangle JKL has coordinates J(−2, −3), K(−5, −2), and L(−6, −7). The triangle is reflected across the y-axis. (PLS HELPP)
Answers
Answer:
J ' (2, -3)
K ' (5, -2)
L ' (6, -7)
The diagram is below
=======================================================
Explanation:
The y axis reflection rule you use is [tex](x,y) \to (-x,y)[/tex]
The x coordinate flips in sign, positive to negative or vice versa.
The y coordinate stays the same.
For example, the point J(-2,-3) moves to J ' (2, -3). The same thing happens to the other points as well.

PLEASE HELP DUE TODAY DO A AND B PARTS PLEASE PLEASE HELP ME FIGURE OUT THE LENGTH 100 POINTS
Answers
Answer:
Length A: 5 ft
Width B: 4 ft
volume = 88 ft³
Step-by-step explanation:
Length A: 8 - 3 = 5 ft
Width B: 8 - 4 = 4 ft
Volume
The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).
Volume of a rectangular prism = width x length x height
Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³
Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³
Total volume = 64 + 24 = 88 ft³
Now volume of first prism
L=8B=2H=3[tex]\\ \tt\hookrightarrow V=LBH[/tex]
[tex]\\ \tt\hookrightarrow V=8(2)(3)[/tex]
[tex]\\ \tt\hookrightarrow V=48ft^3[/tex]
For next prism
L=5B=4H=2[tex]\\ \tt\hookrightarrow V=5(4)(2)=40ft^3[/tex]
Total volume=40+48=88ft^3Determine whether a triangle with the given side lengths is a right triangle.

Answers
Answer:
A. {(0, 3), (1, 6), (2, 9)}Step-by-step explanation:
Rewrite the function in the slope-intercept form:
y - 3 = 3xy = 3x + 3The ordered pairs:
x = 0 ⇒ y = 3 ⇒ (0, 3)x = 1 ⇒ y = 6 ⇒ (1, 6)x = 2⇒ y = 9 ⇒ (2, 9)x = 3 ⇒ y = 12 ⇒ (3, 12)Correct set is A

Step-by-step explanation:
SO YOU HAVE TO FIND LENGTH OF THE TRIANGLE
Step-by-step explanation:
I just answered 1.
by using the principle of similar triangles (all angles are the same between the 2 triangles, and the ratio of a corresponding pair of sides is the same for all pairs of sides) we get
AB = 2×38 = 76
AC = 2×24 = 48
WX = CB/2 = 66/2 = 33
2.
the upper small triangle and the whole big triangle are similar triangles.
and we see the ratio of the legs is 1/2 (each leg of the small triangle is half of the leg of the large triangle).
therefore,
3x = 24/2 = 12
x = 12/3 = 4
3.
AC = 16
because the height of C splits the baseline precisely in half, it means that this is at least an isoceles triangle (both legs have the same length). therefore the answer.
AC = CB = 16.

Hi!
I can help you with joy! :)
Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept)
Now, where does the graph touch the y-axis?
It touches the y-axis at (0,1)
Thus, the y-intercept is 1.
I hope this helps you!

Which equation describes the line with a
slope of 2 that contains the point (4, -3)?
Answers
Answer:
y = 2x - 11
Explanation:
using the formula:
[tex]\boxed{y-y1= m(x-x1)}[/tex] .........where m is slope || y1 is y value || x1 is x value
y - -3 = 2( x - 4 )
y + 3 = 2(x -4)
y + 3 = 2x - 8
y = 2x - 8 - 3
y = 2x - 11
