Answer:
Solving below systems of equations using linear combination method we get
x = -7
y = 5
Step-by-step explanation:
Linear combinations which is also commonly known as the addition method is used for solving the system of equations without graphs
Step 1: arrange the equation in standard form
2x + 3y = 1----------------------(1)
2x + y = -9--------------------(2)
Step 2: Set one of the coefficient to opposite sides
So lets multiply eq(2) with negative sign, so
2x + 3y = 1
-2x - y = 9
Step 3: Perform Addition
2x + 3y = 1
-2x - y = 9
-----------------------
0x +2y = 10
--------------------------
Step 4: Solve for y
2y =10
y = 5
Step 5: Substitute y value in equation(1)
2x + 3(5) = 1
2x + 15 =1
2x = 1-15
2x =-14
x = -7

Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
Every value{0.01, 0.29, 85%} can represent the probability of an event occurring except option d that is 1.5.
Given to us,
a.) 
b.) 0.29
c.) 85%
d.) 
The probability help us to know about the probability of specific events occurring.
For a sure event, the probability is always 1,
while for an event that will never happen the probability is always 0.
Thus, probability(p), 
.
Now looking at the options,
a.) = 0.01
b.) 0.29
c.) 85% = 0.85
d.) = 1.5
Now comparing each option with .
Therefore, the only option which is not feasible is option d that is 1.5.
Hence, every value{0.01, 0.29, 85%} can represent the probability of an event occurring except option d that is 1.5.
