Answer:
Number of week they have same amount = 4 week
Step-by-step explanation:
Given:
Amount Joe have = $14
Joe's saving per week = $10
Amount Josh have = $26
Josh saving per week = $7
Find:
Number of week they have same amount
Assume;
Number of week they have same amount = a
So,
(14 + 10a) = (26 + 7a)
3a = 12
a = 4
So,
Number of week they have same amount = 4 week
Answer: 18
Step-by-step explanation:
Area of triangle = (0.5) × base(b) × height(h)
Base of triangle = 8
Height of triangle = 15
Area of triangle = (0.5) × 8 × 15 = 60
Volume of triangular prism = B × height
Where h = height
B = area of triangle
Volume of triangular prism = 1080
Find the height(h) of the triangular prism
Volume of triangular prism = B × height
1080 = 60 × h
h = 1080 / 60
h = 18
Answer: y = -4x - 4
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.
First, find the slope. To find the slope, use this "formula" : 
Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:

Then, pick any point to plug into the equation. Let's use (0,-4)
Finally, plug everything into the equation:
y - - 4 = -4(x - 0)
y + 4 = -4x
y = -4x - 4
The answer to this question is:
x y
(1,-5) so the equation would be -5=-7+2(1)
-5=-7+2 -7+2=-5
-5=-5
hope this helps;)
