Answer:
-1
Step-by-step explanation:
given f(x)=-4x+7 find f(2)
f(2) means question : if x=2, f(2)=?
f(2)= -4x2+7=-1
It’s called the associative law you can add numbers in any order you want
Answer:
C; Substitution property
Step-by-step explanation:
Here, we want to find the justification that justifies the written equation;
If PQ + RS = PS
and RS = XY
then PQ + XY = PS
What we simply did is to substitute RS for XY in the second equation;
The correct answer is Substitution property
It can be fully referred to as the substitution property of equality.
What it simply means in a nut shell is that since XY and RS are equal, then in any addition or arithmetic equation, we can make a substitution of XY for RS since they are equal to each other
These intercepts<span> are plotted in Figure 3.1 and the line </span>3x<span> + </span>2y<span> = </span>12<span> is drawn through them. Figure 3.2: Adding the graph of </span>y<span> = </span>x<span> + 1. The second equation </span>y<span> = </span>x+ 1 has slope-intercept<span> form </span>y<span> = mx + b. Hence, the slope is m = 1 and the </span>y-intercept<span> is (0, 1).</span>
