Answer:
1.8 cm
6.3 cm²
Step-by-step explanation:
AC⊥BC
BD=BC=x
- (x+5)²+x²=7²
- x²+10x+25+x²=49
- 2x²+10x- 24=0
- x²+5x-12=0
- x=1.8
BC= 1.8 cm
Area of ABC= 1/2*1.8*7= 6.3 cm²
Answer:
y-inctercept=4, x-intecept=7
Step-by-step explanation:
I did it with the standard to slope again!


Now don't get confused here, 4 is the y incetecept, not -4.
When y=0, x=7
UPDATE:
To determine x and y intercept using graph, see where the line intersects at the x or y axis.
Answer:
The answer is "I don't know, honestly."
Step-by-step explanation:
Your answer would be C) 12
