Hey there!
Inequality notation:
Domain- -4<x<∞
Range- -1<y≤5
Set notation:
Domain- {x|-4<x<∞}
Range- {y|-1<y≤5}
Interval notation:
Domain- (-4,∞)
Range- (-1, 5]
Function notation:
f(2), y=5
f(x)=0, x=-3
Let me know if this helps :)
You could also say.
13 x
--- = ---
1 7
Multiply across.
1x=13×7
1x =91
Divide both sides by one.
x=91.
91 cups of yoygurt are needed to make 7 Smoothies.
Or you could do it the easy way.
whatever makes you happy. :)
Answer:
Step-by-step explanation:
length of blanket × width of blanket = (2a + 1)(a) = 2a2 + a.
Since we’re told the area covered by the blanket is 28 square feet, we know that
2a2 + a = 28.
To solve this equation, we need to rearrange the terms so that we have a polynomial set equal to 0:
2a2 + a – 28 = 0.
Then we factor:
(2a – 7 )(a + 4) = 0.
The two solutions to this equation are a = 3.5 and a = -4. a = -4 sure doesn’t make sense, because we can’t have a blanket that’s -4 feet wide. That won’t cover even one of Janna’s toes. The blanket must be 3.5 feet wide.
To find the length, we plug the width 3.5 in for a in the expression 2a + 1. The length of the blanket is
2(3.5) + 1 = 8 feet
We can easily check our answers by multiplying the width and length of the blanket, and seeing if we do end up with 28.
(3.5)(8) = 28
Answer:
x = 73.8
Step-by-step explanation:
to find the blue line:
tan(50) = 41/a
a = 41/tan(50)
a = 34.4 to 1 decimal place
to find x:
tan(65) = x/34.4
x = 34.4tan(65)
x = 73.8 to 1 decimal place
