Answer:
The value of the x variable is 30.
Step-by-step explanation:
Since the triangles are similar, the corresponding sides of both triangles have a common ratio. The 18:12 ratio of side LK and QR is equal to 2:3, and the 21:14 ratio of sides JL and PQ is also equal to 2:3. Based on this, we know that 2/3 * x = 20, so we isolate the x variable by dividing both sides of the equation by 2/3 to get the answer: x = 30.

If the vertex of a parabola is (3,5), what is the symmetry
Answers
Answer:
axis of symmtery: x = 3 or h = 3
Step-by-step explanation:
The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.
In the standard form of quadratic equation, y = ax² + bx + c, the equation of the axis of symmetry is: [tex]x = \frac{-b}{2a}[/tex].In the vertex form of the quadratic equation, y = a(x - h)² + k, the equation of the axis of symmetry is: [tex]h = \frac{-b}{2a}[/tex].Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.
Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.

A company makes a beverage that must have 12% real-juice content. How many gallons of beverage with 9% real-juice content must be mixed with 3000 gallons of beverage with 15% real-juice content to achieve the desired 12% real-juice content?
Answers
first lets change this problem into an equation...
0.09*x+0.15*3000=0.12(x+3000)
Step 1: Simplify both sides of the equation.
0.09x+(0.15)(3000)=0.12(x+3000)
0.09x+(0.15)(3000)=(0.12)(x)+(0.12)(3000)
0.09x+450=0.12x+360
Step 2: Subtract 0.12x from both sides.
0.09x+450−0.12x=0.12x+360−0.12x
−0.03x+450=360
Step 3: Subtract 450 from both sides.
−0.03x+450−450=360−450
−0.03x=−90
Step 4: Divide both sides by -0.03.
-0.03x/-0.03=-90/0.03

Sydney would have $7 in her account in 3 weeks.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
Sydney put $1 in her Piggy bank. For the next three weeks Sydney doubled the amount she put in her bank.
Assume that she saves $y in [x] weeks. We can model the linear function of her saving as -
y = 1 + 2x
or we can write -
y = 2x + 1
For x = 3, we will have -
y = 7
Therefore, Sydney would have $7 in her account in 3 weeks.
