If she has 7 stacks of 7 dimes:
7x7=49 dimes
If she has 8 stacks of 6 nickels:
8x6=48 nickles
Right off the bat we know that the y-intercept is going to be 5 because of the second co-ordinate.
Now for the slope, because the y co-ordinate doesn't change, it has no slope so the equation is simply: y=5
Hope this helps :)
Answer:
Step-by-step explanation:
hello :
h(t) = -t²+8t
the highest point is the vertex of this prabola (-b/2a ; h(t) )
a= -1 and b= 8 -b/2a = - (8)/2(-1) = 4
h(4) = -(4)²+8(4) = -16+32 = 16
first answer : 16
second answer : 4
Answer: multiple the length vu the width
Step-by-step explanation:
Answer:
57 and 76
Step-by-step explanation:
the ratio = 3 : 4
=> the sum : 3+4=7 ( equivalent with 133)
so the numbers are :
3/7 × 133 = 57 and
4/7 × 133 = 76.
