Answer:
Step 5 is incorrect because a previous step is incorrect
Step-by-step explanation:
Step 1 correct
Step 2 correct
Step 3 correct
Step 4 incorrect: It must be
y² - 10y + 25 = 2x + 23
Step 5 incorrect because step 4 incorrect
Step 5 must be : 1/2(y - 5)² - 23/2 = x
Set up a proportion: 5/14=25/x and you know 25=5*5 so you do the same to the bottom 14*5=70 so the shadow of something 25 feet high is 70 feet long.
Answer: 70 feet
Answer: 5000 cm is greater than 5 m
Step-by-step explanation:
When you convert 5000 cm to m 5000 cm is equal to 50 m so 5000 cm is greater than 5 m
Answer:
x=-79/4, y=-45/8. (-79/4, -45/8).
Step-by-step explanation:
-2x+4y=17
3x-10y=-3
---------------
3(-2x+4y)=3(17)
2(3x-10y)=2(-3)
----------------------
-6x+12y=51
6x-20y=-6
------------------
-8y=45
y=45/-8=-45/8
3x-10(-45/8)=-3
3x+450/8=-3
3x+225/4=-3
3x=-3-225/4
3x=-12/4-225/4
3x=-237/4
x=(-237/4)/3
x=(-237/4)(1/3)
x=-237/12=-79/4
