Given equations : Equation A: 4y -3x =16 and
Equation B: -x-8y =3.
We are given a<em> point (-5,0.25) plugging it in first equation</em>
4(0.25) -3(-5) =16
1+15 =16.
16 =16 <em>: Satisfies first equation.</em>
Plugging (-5,0.25) it in second equation.
-(-5)-8(0.25) =3.
5 - 2 = 3.
3=3 <em>: Satisfies first equation.</em>
<h3>Therefore, they are the only values that make both equations true.</h3>
Answer:
there are 20 trumpet players
Step-by-step explanation:
trumpet players=3x-10
saxophone players= 3x
3x + 10 = 3x
3x - 3x=10
therefore x = 10 players
trumpet players = 3x -10
= 3(10)-10
=30-10
= 20 players

Answer:</h2><h2>
The cost of ketchup bottle, x = 2.89</h2><h2>
The cost of mustard bottle, y = 1.59</h2>
Step-by-step explanation:
Let the ketchup be represented as x and mustard as y
Briana bought 3 bottles of ketchup and 2 bottles of mustard and for $11.85
3x + 2y = 11.85 ...(1)
Logan bought 2 bottles of ketchup and 5 bottles of mustard for $13.73.
2x + 5y = 13.73 ...(2)
Multiplying eq (1) by 2, we get
6x + 4y = 23.7 ...(3)
Multiplying eq (2) by 3, we get
6x + 15y = 41.19 ...(4)
Subtracting eq (3) from (4),
we get 11y = 17.49
y = 1.59, substitute it in eq(1), we get
x = 2.89
Therefore, the cost of ketchup bottle, x = 2.89
The cost of mustard bottle, y = 1.59
Ok so all you have to do is multiple 9 And 4 ok then you will get you answer
Hope this helps

<span>Using the Pythagorean theorum we can solve this v a^2+b^2= c^2. A is the distance from base of house to ladder A= 1.5, c ifls length of ladder, c= 10. (1.5)^2 + ;b^2 = (10)^2. Solve for b. B= 9.88. 12 foot height of house - 9.88 feet to top of angled ladder = 2.11 from top of ladder to edge of roof</span>
