Write the equation of the line passing through the points (15,4) and (-3,-3) please helppp 10 points pleaseeeeeeeeeee
Answer: [tex]y = \frac{1}{3}x-2[/tex]
This is the same as writing y = (1/3)x - 2
Slope = 1/3
y intercept = -2
======================================================
Explanation:
We first need to determine the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-3-3}{-3-15}\\\\m = \frac{-6}{-18}\\\\m = \frac{1}{3}\\\\[/tex]
Then we'll use this value of m, along with (x,y) = (15,3), to determine the y intercept b value.
[tex]y = mx+b\\\\3 = (1/3)(15)+b\\\\3 = 5+b\\\\3 - 5 = b\\\\-2 = b\\\\b = -2[/tex]
You could use the other point (-3,-3) as well
[tex]y = mx+b\\\\-3 = (1/3)(-3)+b\\\\-3 = -1+b\\\\-3 +1 = b\\\\-2 = b\\\\b = -2[/tex]
Either way, we end up with the same y intercept. You don't need to show both sets of steps when computing b. You only need to pick one set of steps.
Since m = 1/3 and b = -2, we go from y = mx+b to y = (1/3)x - 2 which is the same as writing [tex]y = \frac{1}{3}x-2[/tex]
Answer:
y = 7/18 - 11/6
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - 4 / -3 - 15
-7/-18
= 7/18
y = 7/18x + b
4 = 7/18(15) + b
4 = 35/6 + b
-11/6 = b

3 A piece of ibbon of lengh 84 cm is divided
into three pieces in the ratio 1:47. Calculate the
length of the longest pieces
?
Add the 3 ratio portions together: 1 + 4 + 7 = 12
Divide total length by 12:
84/12 = 7
Multiply each ratio portion by 7:
1 x 7 = 7
4 x 7 = 28
7 x 7 = 49
The longest piece is 49 cm
Answer:
49cm
Step-by-step explanation:
1x+4x+7x=84
12x=84
X=7
4*7=28
7*7=49
So we can see 49cm is the longest.

Please help me with this problem it is pair each of triangles are similar but not drawn to scale. Calculate any lettered lengths
b = 5.5m a = 6m
b = 17cm a = 80cm
Step-by-step explanation:
The second triangle in the pair is a scaled-up version of the first triangle.
To find b in the first triangle you do 11/2 = 5.5m
To find a in the second triangle you do 3*2 = 6m
To find b in the third triangle you do 68/4 = 17cm
To find a in the fourth triangle you do 20*4 = 80cm

Use the given information to write an equation of each parabola.
The parabola has focus (-8.0) and vertex at the origin
Step-by-step explanation:
use y^2=4px
p is the distance from the vertex to the focus, which is 8 units left
y^2=4(-8)x
y^2=-32x
Use y²=4px where p is the distance from the vertex to the focus,
p = 8 to the left,
so p = -8
Plug that in:
y² = 4(-8)x
Sole / simplify / multiply:
y² = -32x
