Answer: x = -5, 3/2 y = 10, 7/2
Explanation:
y = 2x^2 + 6x - 10 (1)
y = - x + 5 (2)
=> 2x^2 + 6x - 10 = - x + 5
2x^2 - 7x - 15 = 0
(2x - 3)(x + 5) = 0
=> 2x - 3 = 0
2x = 3
x = 3/2
=> x + 5 = 0
x = -5
According to (2):
y = -x + 5
y = -(-5) + 5
y = 5 + 5 = 10
y = -x + 5
y = -(3/2) + 5
y = -(3/2) + 10/2
y = 7/2
Answer:
20%
Step-by-step explanation:
Here, we want to calculate the percentage increase in the price of a can of green beans
Mathematically, we use the formula below;
(new price - old price)/old price * 100%
From the question;
old price = $0.50
new price = $0.60
So we have;
(0.6-0.5)/0.5 * 100%
= 0.1/0.5 * 100%
= 20%
Given that the two angles are congruent, the numerical value of x is 12.
<h3>What is the numerical value of x?</h3>
Given the figure in the image.
Note that; corresponding angles are congruent if the transversal intersects two parallel lines
Hence,
( 8x - 4 ) = 92
We solve for x
8x - 4 = 92
8x = 92 + 4
8x = 96
x = 96/8
x = 12
Given that the two angles are congruent, the numerical value of x is 12.
