Answer:
(-18, -3)
Step-by-step explanation:
To solve this system of equations, use the substitution method.
Steps for substitution method:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x.
Step 3: Solve this, and you have the x -coordinate of the intersection.
Step 4: Then plug in x to either equation to find the corresponding y -coordinate.
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2

Answer:
tom ate sandwiches of cucumber and also had tea
Step-by-step explanation:
The computation is shown below:
P:I = popcorn
Q:I = raisins
R:I = cucumber sandwiches
S:I = sodas
T:I = tea
1. It could be either popcorn or raisins
2. If i take sandwiches of cucumber so it also had soda
3. Do not drink soda or tea
Now considered the negation of 1, 2 and 3
So,
Now combining 4, 5 and 6
We get
So, tom ate sandwiches of cucumber and also had tea
Answer:
150
Step-by-step explanation:
The 100% of a number is represented by N and 60% of N = 90
To find the whole we multiply 90 with 100 and divide that by 60
100*90/60 = 150
