Answer:
Step-by-step explanation:
4/3 = t/7
Multiply by 7 on both sides
4/3 x 7 = t
28/3 = t
X^2+34=74
minus 34 from both sides
x^2=40
sqrt both sides
x=+/-√40
x=+/-2√10
the values 2√10 and -2√10 are soltuions for x
The x intercept would be -2
and the y intercept would be 21

Answer:
Correct answer: Nickels x = 11 and pennies y = 9
Step-by-step explanation:
We will first define the variables in the system:
Let be nickels x and pennies y
We will form a system to solve this problem:
5 x + 1 y = 64
x + y = 20/ · (-1)
we will first multiply the second equation by -1 and add it by the first and get:
4 x = 44 ⇒ x = 44 / 4 = 11 nickels
x = 11 nickels
from the other we get y
y = 20 - x = 20 - 11 = 9 pennies
y = 9 pennies
God is with you!!!
