Answer:
x = taco
y = milk
x + y = 2.10$
x = 2.10 - y
2x + 3y = 5.15$
2(2.10 - y) + 3y = 5.15$
4.20 - 2y + 3y = 5.15
y = 0.95
2x + 3(0.95) = 5.15
2x = 5.15 - 2.85
x = 1.15
So one taco is 1.15$ and a small glass of milk is
0.95$
(a) The vertical motion equation for the ball is h = 8 + 48t - 16t².
(b) The time for the ball to hit the ground is 3.15 s.
(c) The time for the ball to travel 56 ft above the ground is 0.79 s.
<h3>Vertical motion equation for the ball</h3>
The vertical motion equation for the ball is calculated as follows;
h = h₀ + vt - ¹/₂gt²
h = 8 + 48t - ¹/₂(32)t²
h = 8 + 48t - 16t²
<h3>Time for the ball to hit the ground</h3>
0 = 8 + 48t - 16t²
solve the above quadratic equation with formula method;
a = -16, b = 48, c = 8
t = 3.15 s
<h3>Time for the ball to be 56 ft above the ground</h3>
- let upward motion be positive
h = 8 + 48t + 16t²
56 = 8 + 48t + 16t²
0 = -48 + 48t + 16t²
solve the above quadratic equation with formula method;
a = 16, b = 48, c = -48
t = 0.79 s

Answer:
2/7
Step-by-step explanation:
This is easy! No need to over think it btw!
1) whenever you divide by a whole number such as in this case;4. You need to put a 1 under 4... like this: 4/1 (so it can become a fraction!)
2) Use KEEP, CHANGE, FLIP when you are dividing fractions!
8/7 --> you keep that number
÷ ---> × = you change the division sign into multplication sign
4 ---> 1/4 = you put 1 over 4 and flip it which you get from 4/1 --> 1/4
3) Your would look like this....
8/7 * 1/4 = ?
4) Muliply horizontally; 8 * 1 = 8 , 7 * 4 = 28
5) You get 8/28 Don't forget to simplify!!!
6) 8/4 / 32/4 = 2/7
ALSO, here's an example of KEEP, CHANGE, FLIP:
Answer:
1500 x 10 = 15,000
salary after 10 years is 58,000 + 15,000 = 73,000

Answer:no
Step-by-step explanation:
The answer is (-1,-7)
Y=4x-3
(4x-3)-2x=-5
2x=-2
X=-1
Y=4(-1)-3=
-7
(-1,-7)
