Anything times 0 is 0 so the answer is 0
3.4(x+1.58)= - 11.288
Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)
3.4x + (3.4×1.58)= - 11.288
3.4x + 5.372 = -11.288
Step 2: Bring 5.372 to the right side by subtracting it to both sides
3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)
3.4x + (0) = (-16.66)
3.4x = -16.66
Step 3: Isolate x by dividing 3.4 to both sides
x = -4.9
Hope this helped!
Answer:
$2,184
Step-by-step explanation:
$6,500 x 2.8% = annual interest
6,500 x 2.8% = $182 annual interest
$182 x 12 years = interest earned in 12 years.
182 x 12 = $2,184
Answer:
The price of the jacket was $31.43
Step-by-step explanation:
Let the cost of a jacket = x
Let the cost of a pair of pants = y
Such that,
x + y = $66.12.........Equation 1.
From the conditional statement,
x = y - $3.26..........Equation 2.
Solve both equations simultaneously, using the substitution method
From Equation 2;
x = y - 3.26
Substitute y - 3.26 for x in Equation 1.
x + y = 66.12, now becomes,
y - 3.26 + y = 66.12
collect like terms
y + y = 66.12 + 3.26
2y = 69.36
y= 69.36/2 = $34.69.
Put y = $34.69 in Equation 2. to obtain x
x = 34.69 - 3.26
x = $31.43
The interval over which the given quadratic equation decreases is: x ∈ (5, ∞).
<h3>How to find the interval of quadratic functions?</h3>
Usually a quadratic graph function decreases either when moving from left to right or moving downwards.
In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.
Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).
