23/2 = 11 1/2 or 11.5....its gonna be midway between 11 and 12 on a number line.
Answer: 1. y=2/3x+4
2. y=-4x-7
3. y=3x-5
4. y= -5/4x + 2
Hope I helped! :)
Step-by-step explanation:
Answer : 1 1/5
Step by step explanation :
2/5 orange = 1/3 pineapple
There are multiple ways to go about with this problem, but let’s just go with one of the simplest : Multiplying by the same thing on both sides.
How do we get from 1/3 to 1? We multiply by 3. So, to find how many cups of orange juice we use we need to multiply by 3 too.
2/5 times 3 = 6/5
6/5 = 1 and 1/5
So 1 and 1/5 is the answers, have a great day, and mark brainliest if possible!
Answer:
y = (x + 9)² + 9
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
given a parabola in standard form : ax² + bx + c : a ≠ 0
the the x-coordinate of the vertex is
= - 
y = x² + 18x + 90 is in standard form
with a = 1, b= 18 and c = 90
= - 
= - 9
to find the corresponding y-coordinate substitute x = - 9 into the equation
y = (- 9)² + 18(- 9) + 90 = 81 - 162 + 90 = 9
⇒ y = (x + 9)² + 9 ← in vertex form
Answer:
$109
Step-by-step explanation:
<u>Formulas</u>
interest = (principal amount)(rate)(time)
<em>interest = (100)(0.09)(3) = $27</em>
total = principal amount + interest
<em>total = 100 + 9 = $127</em>
