Answer:
x=29 and y=53
Step-by-step explanation:
let y=3x-34 be the first equation (1) and y=2x-5 be the second equation (2)
Using the elimation method, (1)-(2): 0=x-29
-x=-29
x=29
Substitute x=29 into (2),
y=2(29)-5
y=58-5
y=53
So, x=29 and y=53

the equation of the normal to the 2x² + 2y² -4x +4y =12 at the point (-1,1) is
To find the equation of the normal to the given curve at the point (-1,1), you can use the following steps:
Rewrite the given equation in the form "y = mx + b," where m is the slope of the curve and b is the y-intercept.
Find the slope of the curve at the point (-1,1). This can be done by taking the derivative of the equation and evaluating it at x = -1.
The slope of the normal line at the point (-1,1) is the negative reciprocal of the slope of the curve at that point. Calculate this value.
Use the point-slope formula to write the equation of the normal line in the form "y - y1 = m(x - x1)," where (x1, y1) is the point (-1,1) and m is the slope of the normal line.
Substitute the values for x1, y1, and m into the point-slope formula to obtain the final equation of the normal line.
For example, if the given equation is 2x^2 + 2y^2 - 4x + 4y = 12, you can follow these steps:
Rewriting the equation in slope-intercept form, we get: y = -x + 2
Taking the derivative of the equation, we get: y' = -1
The slope of the normal line is the negative reciprocal of the slope of the curve, which is 1/-1 = -1
Using the point-slope formula, we get: y - 1 = -1(x + 1)
Substituting the values into the point-slope formula, we get: y - 1 = -1x - 1
Thus, the equation of the normal line at the point (-1,1) is y - 1 = -1x - 1.
During a clearance sale at a sporting goods store, skateboards were marked down 30%. On Saturday, an additional 25% was taken off the already reduced prices of the skateboards. If a skateboard originally cost $119.50, what was the final price after all discounts? Round to the nearest cent.
The final cost of a skateboard after all the discounts and reductions is $53.775.
Given that, during a clearance sale at a sporting goods store, skateboards were marked down 30%. On Saturday, an additional 25% was taken off already reduced prices of skateboards.
We need to find the final price after all discounts had been taken.
What is the discount?
The basic way to calculate a discount is to multiply the original price by the decimal form of the given percentage rate. To calculate the sale price of any item, we need to subtract the discount from the original price.
Given, that the original cost of the skateboard is $119.50.
Now, 30+25=55
So, the total decrease in percentage is 55%.
The final cost of a skateboard=119.50-55% of 119.50
=119.50-0.55 × 119.50
=119.50-65.725
=$53.775
Therefore, the final cost of a skateboard after all the discounts and reductions is $53.775.

A local company offers you an opportunity to sell discount cards. You will have to pay the company a one-time setup fee of $320. Each card will cost you $6. How many cards would you have to sell before your average total cost per card falls to $10?
Answer:
80 cards would have to sold before your average total cost per card falls to $10
Step-by-step explanation:
To find the number of cards you would have to sell to bring the average total cost per card down to $10, you can use the following formula:
number of cards = setup fee / (average total cost per card - cost per card)
Plugging in the values given in the problem, we get:
number of cards = $320 / ($10 - $6)
Solving this equation gives us:
number of cards = $320 / $4
Dividing 320 by 4 gives us a result of 80, so you would have to sell 80 cards before your average total cost per card falls to $10
Another approach is setting it up as y = mx+b
$10 = (320 + 6x) / x
Where x is the number of cards that you need to sell.
Solving for x, we get:
$10x = 320 + 6x
4x = 320
x = 80

At the end of a snowstorm, Gabriella had 11 inches of snow on her lawn. The
temperature then increased and the snow began to melt at a constant rate of 0.5
inches per hour. Assuming no more snow was falling, how much snow would
Gabriella have on her lawn 3 hours after the snow began to melt? How much snow
would Gabriella have on her lawn after t hours of snow melting?
The snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t
What is a constant rate of change?
A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Constant rate is also called uniform rate which involves something traveling at a fixed and steady pace or else moving at some average speed.
The snow started melting at a rate of 0.5 inches per hour and it is known that 3 hours after the storm ended, the depth of snow was down to 11 inches.
Snow melted in 3 hours = 0.5 * 3 = 1.5 inches
Thus;
The Initial depth of snow = 11 + 1.5 inches = 12.5 inches.
Now, depth of snow on Gabriella's lawn = Initial depth - 0.5(Number of hours)
Let S(t) be the depth of snow on Gabriella's lawn, in inches, t hours after the snow stopped falling.
Hence, the snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t

The angles of a triangle are 120°, (x + 16)°, and x°.
What is the value of x?
Pls explain how you get the answer
The triangle has a value of x=22°.
What is a triangle?The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles.
Having three sides, a triangle is a form. Each kind of triangle has a unique name. The size of the angles and side lengths determine what kind of triangle it is (corners). Triangles can be classified as equilateral, isosceles, or scalene depending on how long their sides are.
The sum of all the angles in a triangle must be °
120° + (x+16)° + x° = 180°
2x + 136° = 180°
2x = 180° - 136°
2x° = 44°
x = 22°

In the fall of 1996, tuition and registration fees for undergraduates at the University of California, Davis was $1411. In the fall of 2018, tuition and fees
were $14,402. Find the percent increase. Round your answer to the nearest tenth percent
% increase
To find the percent increase, we need to calculate the difference between the new tuition and fees and the old tuition and fees, and then divide this difference by the old tuition and fees and multiply by 100%.
The difference between the new tuition and fees of $14,402 and the old tuition and fees of $1411 is $14,402 - $1411 = $12,991.
The percent increase is: ($12,991/$1411) * 100% = 9.2 * 100% = 920%
Therefore, the percent increase in tuition and fees between the fall of 1996 and the fall of 2018 was 920%, rounded to the nearest tenth percent.

The maximum height of the arrow is
feet.
c. How long does it take the arrow to hit the ground? Round your answer to the nearest second.
It takes about seconds for the arrow to hit the ground.
a) The function in vertex form is; y = -16(x - 3.5)² + 198
b) The maximum height if the arrow is; 198 feet
c) The time that it takes the arrow to hit the ground is; 16 seconds
How to write the quadratic equation in vertex form?We are given the function as;
y = -16t² + 112t + 2.
where;
y is the height (in feet) of an arrow
t is the time in seconds after it is shot from a bow
This is the equation of a vertical parabola open downward
The vertex is a maximum
The general form of a quadratic equation in vertex form is;
y = a(x - h)² + k²
where (h, k) is the vertex coordinate
a) y = -16t² + 112t + 2
This is in standard form and using completing the square, we can write in vertex form as;
y = -16(x - 3.5)² + 198
b) The vertex is the point (3.5, 198)
The maximum height of the arrow represents the y-coordinate of the vertex of the function
Thus, the maximum height of the arrow is 198 feet
c) We know that when the arrow hits the ground, the value of y is equal to zero. Thus, at y= 0, we have;
-16(x - 3.5)² + 198 = 0
Rearranging gives;
(x - 3.5)² = (198/16)
(x - 3.5) = ±√(198/16)
(x - 3.5) = ±12.375
x = 12.375 + 3.5
x = 15.875 ≈ 16 seconds which is the time it will take to hit the ground.
