the price of a 70 inch tv was reduced from 800$ to 600$ on black friday by what percentage was the tv reduced
well, from 800 to 600 is 200 bucks.
if we take 800 to be the 100%, what is 200 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 800 & 100\\ 200& x \end{array} \implies \cfrac{800}{200}=\cfrac{100}{x}\implies 4=\cfrac{100}{x} \\\\\\ 4x=100\implies x=\cfrac{100}{4}\implies x=25[/tex]
(5,7) (7,9) find slope
Answer:
1
Step-by-step explanation
Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.
In this case:
Y1 = 5
Y2 = 7
X1 = 7
X2 = 9
(5-7)/(7-9) = -2/-2 = 1

What is 8s-3x+4k I’m confused
10 friends decided to buy a joint gift for their best friend. But as it happens, the two gave up and decided to buy her a present themselves. Thus, the remaining 8 friends had to add 50 dollars each to buy the gift.
How much did the gift cost?
Answer:
The answer is $2000
Step-by-step explanation:
8 had to give an extra $50 each.
8 x 50 = 400
400 ÷ 2 ( the two that changed their mind) = 200
Each person was to give $200
10 × 200 = 2000

The effect of Claudia's changing the height of of the triangle from 1 inch
to 3 inches is the option;
The height of the triangle changed to three inches but the width remained 1 inchWhich option gives the effect of changing the height?The given dimensions of the equilateral triangle Claudia added are;
Height of the triangle = 1 inch
Width of the triangle = 1 inch
The value Claudia typed in the Shape Height box = 3
Required:
What happened to the shape after she press Enter
Solution:
By entering 3 in the Shape Height box, changes the height of the
equilateral triangle to 3 inches but the width remains 1 inches

Solve system of equations
3x+6y=18
X+3y=15
Answer:
x = - 12, y = 9
Step-by-step explanation:
Given the 2 equations
3x + 6y = 18 → (1)
x + 3y = 15 → (2)
Multiplying (2) by - 3 and adding to (1) eliminates the term in x
- 3x - 9y = - 45 → (3)
Add (1) and (3) term by term to eliminate x
- 3y = - 27 ( divide both sides by - 3 )
y = 9
Substitute y = 9 into either of the 2 equations and evaluate for x
Substituting into (2)
x + 3(9) = 15
x + 27 = 15 ( subtract 27 from both sides )
x = - 12
Solution is (- 12, 9 )

Which is true about measurements in manufacturing? POSSIBLE ANSWERS: Product quality is not affected by size. Size is not adversely affected if a measurement is off by an inch or two. Some products do not require a high degree of accuracy. Accurate measurements do not require a lot of time or energy.
Answer:
A. Product quality is not affected by size.
Step-by-step explanation:
This statement is true because the quality of a product is not a measure of its size, which is a quantifiable factor. This means that we can have a very small-sized product which has very good quality. Size also depends on the product being manufactured. Quality is rather measured by how good the materials used in the production are.
If inferior materials are used in the production, then the product, no matter how small or big they are, would lack quality. To obtain a good and accurate measurement, a lot of time and energy should be invested.

A parabola has focus (5,7) and directrix y=0(the X-axis). Write an equation that says point (x,y) is on the
parabola.
Answer:
Step-by-step explanation:
focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.
The equation of a parabola with the given focus and directrix is x²-10x+74=14y.
What is an equation of a parabola?A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line
Given that, a parabola has focus (5,7) and directrix y=0.
When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y
Here, y=c=0
Now, (x-5)²+7²-0²=2(7-0)y
x²-10x+25+49=14y
x²-10x+74=14y
Therefore, the equation of a parabola is x²-10x+74=14y.

Write the equation of a line in slope-intercept form that crosses through the points (-3, -7) and (12, 3)
Step-by-step explanation:
Hey there!
The points through which the line passed are; (-3,-7) and (12,3).
Note: Use double point formula.
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Keep all values.
[tex](y + 7) = \frac{3 + 7}{12 + 3} (x + 3)[/tex]
Simplify it.
[tex](y + 7) = \frac{10}{15} (x + 3)[/tex]
[tex](y + 7) = \frac{2}{3} (x + 3)[/tex]
[tex]y + 7 = \frac{2}{3} x + 3 \times \frac{2}{3} [/tex]
[tex]y = \frac{2}{3} x + 2 - 7[/tex]
[tex]y = \frac{2}{3} x - 5[/tex]
Therefore, the required equation is; y = 2/3x - 5.

Answer:
1 solution
Step-by-step explanation:
The coefficients of x are different on each side of the equal sign, so this equation has one solution.
_____
Additional comment
If the x-coefficients are the same on each side of the equal sign, then you need to look at the constants. If they are the same, there are an infinite number of solutions; if they are different, no solutions.
This equation simplifies to ...
3x -3 = 2x +9
x = 12 . . . . . . . . add 3-2x to both sides
The solution of expression by applying distributive property and combining like terms,
⇒ x = 12
Given that,
The mathematical expression is,
⇒ 3(x - 1) = 2x + 9
Now, simplify the expression by applying distributive property and combining like terms,
⇒ 3(x - 1) = 2x + 9
Apply distributive property,
⇒ 3x - 3 = 2x + 9
Combine like terms,
⇒ 3x - 2x = 9 + 3
Therefore, the solution of expression is,
⇒ x = 12

In which choice is y a function of x?
Answer:
First choice
Step-by-step explanation:
Check if a relation is a function by looking at the x's.
No repeated x's? Then it's a function.
Repeated x's but the y is the same y both times? It's a function.
Repeated x's and different y's? NOT A FUNCTION.
