we can always find the x-intercept of any equation by simply setting y = 0, so let's do so
![\bf 4x+3y=36\implies 4x+3(\stackrel{y}{0})=36\implies 4x=36\implies x=\cfrac{36}{4}\implies x = 9 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (9~~,~~0)~\hfill](https://tex.z-dn.net/?f=%5Cbf%204x%2B3y%3D36%5Cimplies%204x%2B3%28%5Cstackrel%7By%7D%7B0%7D%29%3D36%5Cimplies%204x%3D36%5Cimplies%20x%3D%5Ccfrac%7B36%7D%7B4%7D%5Cimplies%20x%20%3D%209%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%289~~%2C~~0%29~%5Chfill)
First let us calculate the total cost before tax:
1.06 * cost = 16.43
cost = 15.5
Therefore the cost of sunscreen is:
2 * Sunscreen + 6.50 = 15.5
2 * Sunscreen = 9
Sunscreen = $4.50
<span>Hence each bottle of sunscreen cost $4.50</span>
Let the kite is the quadrilateral ABCD with the two pairs of adjacent congruent sides. (the diagram is also attached)
<span>Now, its given in question, see from figure,
AB is congruent to AD </span>
BC is congruent to DC
Now, let us join the points A & C to form AC ; and points B and D to form BD.
So, AC is common side to triangles ABC and ADC.
So, Because AB ≈AD
BC ≈ DC
And, AC is common, therefore,
<span>triangle ABC is congruent to triangle ADC
</span>
⇒∠ ABC ≈ ∠ADC (These are the angles between the non-congruent sides)
Answer:
Step-by-step explanation:
6x-8y=12
5x+8y=-1
add them
11x=11
x=1
y=-3/4
