Answer:
3x - y = -7
Step-by-step explanation:
put into slope-intercept form the equation becomes <em>y = 3x + 7</em>
parallel lines have the same slope, in this case the slope is 3
Answer:
Step-by-step explanation:
4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)
5) Cost of top = $9
Cost of 3 top = 9*3 = $27
Cost of skirt = $x
Cost of 3 skirt = 3x
Cost of 3 skirt and 3 top = 3x + 27
Cost of 2 skirt = 2x (as she bought 5 skirts)
Cost of her purchase = Cost of 3skirt &3 top and 2skirt
= (3x + 27) + 2x
= 5x +27
6) Cost of 5 nail polish bottle = 5p
Cost of two lip gloss tube = 2g
Cost of one gift bag = 5p + 2g
Cost of 8 gift bag = 8* ( 5p + 2g)
=8*5p + 8*2g
= 40p + 16g
coordinates are (x,y)
so for each point, go across the x axis and up the y axis
for the first point, you go over 1 unit and up one unit so the point is
(1,1)
for the second point, you go over 1 unit, but up 4 units so the point is
(1,4)
for the third point, you go over 5 units and up 1 unit so the point is
(5,1)
so your answer is
B) (1,1), (5,1), and (1,4)
Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.
Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.
Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.
Answer:
68.04 cm^3
Step-by-step explanation:
The volume of the prism is given by
V = Bh
where B is the area of the base and h is the height
B - area of the triangle
B = 1/2 bh = 1/2 (5.4) (3.6) = 9.72
The volume is
V = 9.72*7
68.04 cm^3
