X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
Help on what where is the question or pic!??
Remark
<em><u>Two remarks</u></em>.
1. The weight of the ostrich is on the numerator of the ratio.
2. You have to change units of one of them to make the units the same.
Step One
Change the 150 kg to grams
150 kg * 1000 gram/1 kg = 150,000 grams
Step Two
Find the % of ostrich to hummingbird
Percent = (150,000 / 2) * 100%
Percent = 75000 * 100% = 7 500 000% larger.
Answer:

Step-by-step explanation:
First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is
.
pls double check these im not super sure
im p sure the first one with || means parallel n second one means perpendicular lol
Answer:
m= ll m= -1/3
m= ⊥ m= 3
Step-by-step explanation:
uh regular slope
m = -1/3
parallel - slope is same
perpendicular - product of slopes is -1
