Solve the system by substitution.
y = 5x
y = -3x + 24
pls help :(
Answers
Answer:
x=3, y=15
Step-by-step explanation:
We substitute 5x for y, getting 5x = -3x + 24. We add 3 x to both sides, and have a equation like this: 8x = 24. Divide by 8 on both sides, and we know that x = 3. Since y is 5x, y is 5*3, which is 15.
Write −1/2x+y=10 in slope-intercept form.

Answer:

Determine whether the system of linear equations has one solution infinitely many solutions or no solution explain your reasoning. y=3x+5 and y=3x-5
Answers
Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.
Step-by-step explanation:
y= 3x + 5
y = 3x- 5
3x + 5 = 3x -5
-3x -3x

What is the solution to the equation -4(2x+3) =2x+6-(8x+2)?
x = -10
x = -8
X=-5/2
x=-4/7
Answers
Answer:
x = -8
Step-by-step explanation:
solve:
-4(2x+3) =2x+6-(8x+2)
-8x-12 = 2x+6-8x-2
-8x-12 = -6x + 4
-2x = 16
x = -8
Hope this helps.
Good Luck
Answer:
[tex]x = - 8[/tex]
Second answer is correct
Step-by-step explanation:
[tex] - 4(2x + 3) = 2x + 6 - (8x + 2) \\ - 8x - 12 = 2x + 6 - 8x - 2 \\ - 8x - 12 = - 6x + 4 \\ - 8x + 6x = 12 + 4 \\ - 2x = 16 \\ \frac{ - 2x}{ - 2} = \frac{16}{ - 2} \\ x = - 8[/tex]

Write the formula for
the function whose
parabola is narrow,
opens downward, has a
y-intercept of (0,-3.14),
and has NO x-intercepts.
Answers
Answer:
Equation of the parabola x² = -12.56 y
Step-by-step explanation:
Explanation:-
Given Y- intercept ( 0, -3.14)
Given Focus is ( 0 , -a) = ( 0, -3.14)
So a = 3.14 center C(0,0)
The graph of the parabola is downwards and the axis of the parabola is Y-axis.
Equation of the standard parabola x² = -4 a y
x² = -4 (3.14) y
x² = - 12.56 y
Conclusion:-
Equation of the parabola x² = -12.56 y

Answers
Answer:
0.20secondStep-by-step explanation:
Given the distance of a swinging pendulum modeled by the equation P(t)=−5cos(2πt)+5, to get the first time the pendulum reaches 3.5cm, we will have to substitute P(t)= 3.5cm into the given equation and calculate the value of 't' as shown;
3.5 = −5cos(2πt)+5
Subtracting 5 from both sides;
3.5-5 = −5cos(2πt)+5-5
-1.5 = −5cos(2πt)
Dividing both sides by -5 will give;
[tex]\frac{-1.5}{-5} = cos2\pi t\\0.3 = cos2\pi t\\2\pi t=cos^{-1} 0.3\\2\pi t = 72.54^{0} \\360t = 72.54^{0} \\t = \frac{72.54}{360} \\t = 0.20secs[/tex]
The first time the pendulum reaches 3.5cm is after 0.20secs

How many intersections are there of the graphs of the equations below? One-halfx + 5y = 6 3x + 30y = 36 none one two infinitely many
Answers
Answer:
infinitely many
Step-by-step explanation:
You have the system
(1/2)x + 5y = 6
3x + 30y = 36
Multiplying the first equation by 6 results in 3x + 30y = 36, which is exactly the same as the second equation. The two graphs coincide, and so there are infinitely many solutions to this system
Answer:
infinitely many
Step-by-step explanation:
1/2x + 5y = 6 ⇒ x+10y=123x + 30y = 36 ⇒ x+10y=12As we see, these are equal lines, they overlap, so there are infinitely many intersections

Sand for the sandbox costs \$4.50$4.50dollar sign, 4, point, 50 per cubic meter. How much will it cost to completely fill the sandbox with sand? \$$dollar sign
Answers
Answer:
$27
Step-by-step explanation:
The dimensions of the sandbox (that is a rectangular prism) are 3m x 2m x 1m.
We need to first find the volume of the sandbox.
The volume of a rectangular prism is:
V = L * W * H
where L = length
W = Width
H = height
The volume of the sandbox is:
V = 3 * 2 * 1 = [tex]6 m^3[/tex]
Sand for the sandbox costs $4.50 per cubic meter.
The cost to completely fill the sandbox is:
4.50 * 6 = $27
