Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 7
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute: f(-3) = 2(-3) + 7
- Multiply: f(-3) = -6 + 7
- Add: f(-3) = 1
Answer:
Statement 3: DC=CD (Common)
Step-by-step explanation:
According from the statement given, consider ΔADC and ΔBCD, we get
AD=BC(opposite sides of a rectangle are congruent)
∠ADC=∠BCD(angles of a rectangle are 90°)
DC=CD(Common)
Thus, by SAS rule, ΔADC≅ΔBCD and by CPCTC AC=BD.
Thus, Statement 3 that is using the common sides of the triangle jimmy can prove the proof.
