Step-by-step explanation:
- 2.3 + (- 5.7)
reminder that + (- ) = -
To obtain - 3.4 it is likely that she added 2.3 to - 5.7
The solution is
- 2.3 - 5.7 = - 8
Answer:
f-1(x)=x-7/3
Step-by-step explanation:
x=4 because it makes up a square and all sides are the same length on a square
Answer:
to get the circumference 3.14×14=43.96
radious is doubled because it is half the diameter
We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6
