Translate the statements into equations. We can use 'x' for dimes and 'y' for quarters.
"<span>A boy has 11 coins in dimes and quarters"
"</span><span>Their value is $1.70"
</span>
<span>
To solve this, we can first solve for one of the variables in the first equation, and then plug that into the second equation:
Subtract 'x' to both sides:
Now plug this value of 'y' into the second equation:
</span>
So this equation could be used to solve the problem.
Answer:
A
Step-by-step explanation:
Given
y - 3x = - 14
Rearrange expressing y in terms of x by adding 3x to both sides
y = 3x - 14, that is
g(x) = 3x - 14 → A
Answer:
C.) y is greater than or equal to -6
Step-by-step explanation:
The range are all the set of y-values that are plotted on the vertical axis (y-axis).
The range starts from -6 and above. Which is y ≥ -6
Therefore, range of the function is said to be:
C.) y is greater than or equal to -6
So, you start by separating the equation into two inequalities and you get
4x+1 > -7 and 4x +1 < 5
Solve these inequalities and you get your final answer:
x > -2 and x < 1
(The equalities symbols are supposed to have the "or equal" line beneath them, I was just too lazy to put them.)
