1) Create was we already know in the equation. 16=-7(-3)+b. (This is using the initial equation of y=mx+b.)
2) Simplify and solve for b: 16=21+b = -5=b
3) Replug your be value into your equation: y=-7x-5.
Answer
y=-7x-5
Words: y equals negative seven x, minus five.
Answer:
1)4x+4y=1, 6x−y=1
x+y=4, x−y=2
x+y=−2,x+2y=2
2)2x+y=3, 2x−8y=19

have a nice day ^_^
Answer:
Step-by-step explanation: solution.. 8/10 of candy bar left over to be split into 1/3 pieces...
(8/10)÷1/3=12/5=2.4pieces
Use law of sine, sinB/AC=sinC/AB
sin122/10.2=sinC/6.8
sinC=sin122*6.8/10.2
use your calculator: C=34
Please use your calculator to double check my numbers.
Answer:
Nate is 32 years old and Anne is 27 years old
Step-by-step explanation:
Let's say that Nate's age is n and Anne's age is a. We know they add up to 59, so: n + a = 59. We also know that their difference is 5 and that Nate is older so we know the equation is: n - a = 5. We just need to solve this system of linear equations:
n + a = 59
n - a = 5
We can add the two equations together:
(n + a) + (n - a) = 59 + 5
2n = 64
n = 32
Knowing Nate's age, we can now calculate Anne's age by plugging 32 into any of the two equations:
32 - a = 5
a = 32 - 5 = 27
Thus, Nate is 32 years old and Anne is 27 years old.
Hope this helps!
