Answer: Second option from the top
Step-by-step explanation:
First, we will simplify the given inequalities.
2x + 7 ≥ 1
2x ≥ -6
x ≥ -3
-
8 - ≤ 5
- ≤ 5
- ≤ -3
x ≥ 9
Now, we will graph them. <em>See attached</em>.
Answer:
Option a) c + s = 5.
Step-by-step explanation:
Let variable c represent acre of corn crop and variable s represent acre of strawberries crop.
5 acres can support corn and strawberries.
Thus, this can be expressed with the help of equation.
Farmer wants to make $5,500 from his crops.
He can make $1,000 per acre of corn and $1,500 per acre of strawberries.
This can be written as:
We have to find the constraint for the given system.
A constraint is something that limits or controls what we want to do. Here, the amount of land is limited and act as a constraint for the given situation.
Thus, the constraint for the given system is
Option a) c + s = 5.
Hi there!
Find the volume of a sphere using the following equation:
V = 4/3πr³
Substitute in the given radius:
V = 4/3π(1)³
V = 4/3π or ≈ 4.19 units³
1. For the first question, asking to write an equation for how much more Max needs to save up, It would simply be 95.00 + n = 150.00.
This is because he has $95 and needs $n more to get to the final amount of $150.
2. For the second question, asking which number being substituted for n makes the equation true, isolate n in the equation to find what it equals. To do this, subtract 95 from both sides.
95 + n - 95 = n < This isolates the variable.
150 - 95 = 55
This means n = 55 (fifty five)
3. The inequality is a bit more complicated since it says less than $5 per week. The way I'd do it would get some kind of answer but because I haven't done inequalities like this in a while, I unfortunately can't help you with this part. I can say, however, that it more than likely has something to do with being between two values, but I'm not sure. Sorry for the inconvenience.
Answer:
Step-by-step explanation:
y=-3x²-4x+7...(*)
3x+2y=18...(**)
use (*) put the value of y in (**) :
3x +2(-3x²-4x+7)=18
3x-6x²-8x +14 -18 = 0
-6x²-5x- 4 = 0
6x²+5x+4 = 0
delta = b² - 4ac a = 6 b=5 c =4
delta = 5² - 4(6)(4)= 25 -96= -71 negatif
so no reals solution
