Jayden and Carson are selling T-shirts and sweatshirts for a fundraiser. Jayden sells 9 T-shirts and 3 sweatshirts for $420. Carson sells 1 T-shirt and 6 sweatshirts for $296.
Write a system of equations (without solving it) representing the price of a T-shirt, t, and the price of a sweatshirt, s
Answer:
9t + 3s = 420
t + 6s = 296
s =44; t = 32
Step-by-step explanation:
Let
Price of a T-shirt = t
Price of a sweatshirt = s
Jayden:
9t + 3s = 420
Carson:
t + 6s = 296
9t + 3s = 420 (1)
t + 6s = 296 (2)
From (2)
t =296 - 6s
Substitute t =296 - 6s into (1)
9t + 3s = 420 (1)
9(296 - 6s) + 3s = 420
2664 - 54s + 3s = 420
2,664 - 51s = 420
-51s = 420 - 2,664
-51s = -2,244
s = 44
Substitute s = 44 into (2)
t + 6s = 296
t + 6(44) = 296
t + 264 = 296
t = 296 - 264
t = 32
s =44; t = 32

Write an equation in point slope form of the line with the given characteristics.
1. Parallel to the line y=3/5x-8; passes through (0,-3)
2. Perpendicular to the line y=-2x-7; passes through (-3,10)
Answer:
1. y + 3 = 3/5(x)
2. y - 10 = [tex]\frac{1}{2}[/tex](x + 3)
Step-by-step explanation:
1.
When a line is parallel to another line, it means that the two lines have the same slope. So, for this first problem, the slope of the other parallel line would have to be 3/5.
In the problem, they've given you a point of (0, -3).
Now, you can can plug everything you know into the point slope formula which is...
y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex]).
[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that you plug in, and m is the slope.
After you plug everything in, you should get:
y + 3 = 3/5(x + 0)
You don't really need to include the 0, so your final equation would be
y + 3 = 3/5(x).
2.
When a line is perpendicular to another line, it means that the slope of the other is its opposite reciprocal. This means that the slope of the perpendicular line would be 1/2. I got this by dividing 2 by 1 and multiplying it by -1.
reciprocal of -2 = -[tex]\frac{1}{2}[/tex] x -1 =
You can do the same thing we did in the previous problem with the point given here, which is (-3, 10).
y - 10 = [tex]\frac{1}{2}[/tex](x + 3)

A ball is thrown upward from a height of 15 feet with an initial upward velocity of 5 feet per second. Use the formula b(t)= -16t2 + 5t + 15 to find the time it takes for the ball to reach the maximum height of the ball. Round to the nearest tenth.
Answer:
Time taken by the ball to reach the maximum height = 5/32 seconds
Step-by-step explanation:
To find the time at which maximum height is reached , we will differentiate the given equation with respect to t
[tex]\frac{db_{(t)}}{dt} = -32t + 5 = 0\\t = \frac{5}{32} \\[/tex]
Substituting this value of t in formula of b(t), we get
[tex]-16 * (\frac{5}{32})^2 + 5 * \frac{5}{32} + 15 \\= 15.390[/tex]

Answer:
[tex]x = - \frac{1}{3} [/tex]
Step-by-step explanation:
1) Simplify 2 - 6 to -4.
[tex]2x \times - 4 = 4(3 + 1 \times x - 2)[/tex]
2) Simplify 1 × x to x.
[tex]2x \times - 4 = 4(3 + x - 2)[/tex]
3) Simplify 3 + x - 2 to x + 1.
[tex]2x \times - 4 = 4(x + 1)[/tex]
4) Simplify 2x × -4 to -8x.
[tex] - 8x = 4(x + 1)[/tex]
5) Divide both sides by 4.
[tex] - 2x = x + 1[/tex]
6) Subtract x from both sides.
[tex] - 2x - x = 1[/tex]
7) Simplify -2x - x to -3x.
[tex] - 3x = 1[/tex]
8) Divide both sides by -3.
[tex]x = - \frac{1}{3} [/tex]
Therefor, the answer is x = -1/3.

answer this question and show work or have an explanation.
Answer:
70
Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70

You found yourself lost in a forest. Give an account of your experience and how you found your way out
Answer:
Step-by-step explanation:
This actually happened to me. I was walking out of a national forest and came up to a stream that I had not crossed. I got my bearings confused and realized I was lost. I knew that if I went Northwest it would be about a 30 mile hike out in heavy woods, with obvious other streams to cross. In the Southeast direction, it would only be about 5 miles.
The sun was out but mostly overhead and no help with directions.
I couldn't wait until the sun went farther West to get my directions. It was a warm Winter day but I wasn't dressed to be there after dark when the temperature fell, even if I did go in the correct direction.
I stuck a stick in the ground and made a mark in the dirt at the end of it's shadow. I sat down for about 15 minutes, then made a new mark in the dirt at the end of the sticks shadow again. I drew a line in the dirt to connect the two marks. This line ran close to the East/West direction, the first mark being the West direction.
I made it out about 5 PM just as the sun was disappearing through the trees.
