Y - 3 = -1/4(x - 4)
y - 3 = -1/4x + 1
y = -1/4x + 1 + 3
y = -1/4x + 4
ok....the y int is (0,4)....the slope is -1/4...
x int can be found by subbing in 0 for y and solving for x
y = -1/4x + 4
0 = -1/4x + 4
1/4x = 4
x = 4 * 4
x = 16....so ur x int is (16,0)
so first plot ur points (0,4)....and since ur slope is -1/4, go down 1 space and to the right 4 spaces, then down 1, and to the right 4....keep doing this and u will cross the x axis at (16,0)
So there are 38 +32 = 70 and for the rest 30 we can assuming 15 + 8 +7
38+32+15+8+7=100
hope this will help you
Answer:
she can buy 6 dolls
Step-by-step explanation:
A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars
Step-by-step explanation:
1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16
