Answer:
[tex]x =12\ or\ -8[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (6,5)[/tex]
[tex](x_2,y_2) = (8,2)[/tex]
[tex](x_3,y_3) = (x,11)[/tex]
[tex]Area = 15[/tex]
Required
Find x
The area is calculated as thus:
[tex]Area = \frac{1}{2}|x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|[/tex]
Substitute values
[tex]15 = \frac{1}{2}|6*(2 - 11) + 8*(11 - 5) + x(5 - 2)|[/tex]
[tex]15 = \frac{1}{2}|6*(-9) + 8*(6) + x(3)|[/tex]
[tex]15 = \frac{1}{2}|-54 + 48 + 3x|[/tex]
[tex]15 = \frac{1}{2}|-6 + 3x|[/tex]
Multiply through by 2
[tex]2 * 15 = \frac{1}{2}|-6 + 3x| * 2[/tex]
[tex]30 = |-6 + 3x|[/tex]
Remove absolute sign
[tex]30 = -6 + 3x\ or\ -30 = -6 + 3x[/tex]
Add 6 to both sides
[tex]36 = 3x\ or\ -24 = 3x[/tex]
Divide by 3
[tex]12 = x\ or\ -8 = x[/tex]
[tex]x =12\ or\ -8[/tex]
So, the coordinates are (-8, 11) or (12,11)

Answer:
x=-7
Step-by-step explanation:
75+x+52+67+x=180
2x+194=180
2x=-14
x=-7
Answer:
x = -7
Step-by-step explanation:
total angle of triangle is 180°
nake an equation.
180°= 75 + (x+52) + (67+x)
180-75-52-67=2x
-14 =2x
Divide both sides by 2 to get the value of x
X= -7

In ΔIJK, i = 850 inches, j = 250 inches and ∠K=80°. Find the length of k, to the nearest inch.
Answer:
886 inches
Step-by-step explanation:
Because we know the length for sides I and J, we can use the pythagorean theorem to get K. 850^2 + 250^2=KY^2. 850^2 = 722,500, and 250^2 = 62,500. 722,500 + 62,500 = 785,000. 785,000 to the square root rounded to the nearest inch is 886 inches.

find the slope between the point (a+b,4m-n) and (a-b,m+2n)
Answer:
m = -3m+3n/-2b
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
Given the coordinates (a+b,4m-n) and (a-b,m+2n)
m = (m+2n)-(4m-n)/(a-b)-(a+b)
m = m+2n-4m+n/a-b-a-b
m = m-4m+2n+n/a-a-b-b
m = -3m+3n/-2b
Hence the required slope is m = -3m+3n/-2b

The reciprocal of 36 = 1 / 36
Therefore, a number minus the product of 36 and it's reciprocal can be express below
x - 36 × 1 / 36Then when it is less than zero, it can be express as follows
x - 36 × 1 / 36 < 0 x - 1 < 0The number(x) which satisfy this condition (x - 1 < 0) is less than 1. This means the numbers are 0 to negative infinity.

[x = 2 , y = 3]
Answer:
x=2
y=3
Step-by-step explanation:
[tex]\left \{{4x+3y=17{} \atop{5x-2y=4}} \right.[/tex]
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
4x+3y=17,5x−2y=4
To make 4x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 4.
5×4x+5×3y=5×17,4×5x+4(−2)y=4×4
Simplify.
20x+15y=85,20x−8y=16
Subtract 20x−8y=16 from 20x+15y=85 by subtracting like terms on each side of the equal sign.
20x−20x+15y+8y=85−16
Add 20x to −20x. Terms 20x and −20x cancel out, leaving an equation with only one variable that can be solved.
15y+8y=85−16
Add 15y to 8y.
23y=85−16
Add 85 to −16.
23y=69
Divide both sides by 23.
y=3
Substitute 3 for y in 5x−2y=4. Because the resulting equation contains only one variable, you can solve for x directly.
5x−2×3=4
Multiply −2 times 3.
5x−6=4
Add 6 to both sides of the equation.
5x=10
Divide both sides by 5.
x=2
The system is now solved.
x=2,y=3

A cylinder has a base radius of 7in and a height of 3in. What is its volume in cubic in,
to the nearest tenths place?
The volume of the cylinder having a radius 7 in and a height 3 in is 461.8 cubic inches.
What is the volume?The volume of the rectangular prism is defined as the space in three-dimension covered by the rectangular prism having the sides Length, Width, and Height.
For the cylinder, the volume will be calculated by the radius and the height of the cylinder.
Given that the height of the cylinder is 3 in and the radius of the cylinder is 7 in.
The volume of the cylinder will be calculated as:-
V = πr²l
V = π x ( 7 )² x 3
V = 461.8 cubic nches
Therefore, the cylinder will have a volume of 461.8 inches.

A restaurant charges $5.00 for a slice of pizza that is 1/3 of a pizza and $4.50 for a slice that is 1/5 of a pizza. One day they cooked 8 pizzas that were all the same size. If they sell all the slices, would they make more money by slicing each pizza into thirds or fifths? How much more? Explain.
Answer:
5thsStep-by-step explanation:
Given that:
Price of whole pizza (A) = 5 × 3 = $15Price of whole pizza (B) = 4.50 × 5 = $22.50They make 8 whole pizzas.
Therefore
Thirds (A) = 15 × 8 = $120Fifths (B) = 22.50 × 8 = $180They'll make more money if they slice it into fifths.
180 - 120 = $60
Because if they slice it into thirds, total profit will be $60 less

When a football is punted, it goes up in the air, reaches a maximum altitude, and then comes back down. We can assume that the football follows a parabolic path. When the ball was kicked it was one foot above the ground. One second later, it was 20 feet above the ground. Four seconds after it was kicked it was 35 feet above the field.
What is the quadratic equation?
Answer
look ate image i just send u that´s the answer on the pice of paper
Step-by-step explanation:
The equation of the parabola is given by y=x²+19
What are quadratic equations?A quadratic equation can be written in the standard form as ax2 + bx + c = 0, where a, b, c are constants and x is the variable. The values of x that satisfy the equation are called solutions of the equation, and a quadratic equation has at most two solutions.
Given here: In t=1 sec the football's height was 20 feet and for t=4 the height of the football was 35 feet.
Let the path of the football be a parabola and facing downward.
Thus the equation of the parabola must be y=-4ax²+c
But the parabola passes through the points (1,20) and (4,35)
Thus substituting the points on the equation of the parabola we get
20=-4×1²×a+c & 35=-4×4²a+c
20=-4a+c &35=-64a+c
Solving for a we get
a=-1/4
Thus c=19
∴The equation of the parabola is given by
y=x²+19
Hence, The equation of the parabola is given by y=x²+19

Rewrite 8x - 7 as the product of two factors
Answer:
factors are any group of number or expressions which, when multiplied, produce another number or expression.
Basic example: 4 can be broken into 2 factors---2 and 2. 2 times 2 = 4
Example using an unknown:
2X + 6 = 2 * (X + 3)
In the given problem, there is no whole-number common factor. A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.
So: 8X + 7 = 8 ( X + 7/8 )
The following would also be correct:
8X + 7 = 4 ( 2X + 7/4 )
