3x + 3y = 12
6x + 11y = 14
9x + 15y = 26
now u wat to cancel out
9x + 15y = 26
9
15y = 26 y = 1.7
9x = 26 x = 2.8
i think this is right i hopw this helps

you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Answer:
(-2,6)
Step-by-step explanation:
3x + 2y = 6
-3x + y = 12
3x + -3x = 0
2y + y = 3y
6 + 12 = 18
3y = 18
3y/3 = 18/3
y = 6
-3x + y = 12
-3x + 6 = 12
-3x = 12 - 6
-3x = 6
-3x/-3 = 6/-3
x = -2

You hike up a mountain. You climb steadily for 2 hours, then take a 30-minute break for lunch. Then you continue to climb, faster than before. When you make it to the summit, you enjoy the view for an hour. Finally, you decide to climb down the mountain, but stop halfway down for a short break. Then you continue down at a slower pace than before. Sketch a graph of the situation. a. Height (feet) Time (hours) b. Is the graph discrete or continuous? Explain your reasoning.
Answers
Answer:
Continuous
Step-by-step explanation:
The graph is considered continuous due to the fact that it can take any amount of height, weight, and temperature. If it was discrete there would be a limit to your hike.

Answer:
[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
Step-by-step explanation:
From the question we are told that the expression [tex]ln(y √x/z[/tex]
[tex]in (y\sqrt{\frac{x}{y}})[/tex]
[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]
[tex]in(xy)=in(x)+in(y)[/tex]
[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
Mathematically
[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

0.625
Answers
Answer:
0.625
Step-by-step explanation:
To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.
Therefore, the answer would be 5/8, or 0.625.
To verify, we can use the other values given in your question.
10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.
You can do the same with the other ratios given.
15/24 simplified is 5/8, which, once again, is 0.625.
Thus, I can say with certainty that the answer is 0.625.

The radius of a circle is 4 inches. What is the area of a sector bounded by 180° arc?
Answers
Answer:
Step-by-step explanation:
If you're asking for the area of the sector, it's the central angle of 360, times the area of the circle, for example, if the central angle is 60, and the two radiuses forming it are 20 inches, you would divide 60 by 360 to get 1/6.
The requried area of a sector bounded by a 180° arc is 8π square inches.
What is an area of the sector?The area of a sector is a portion of the circle enclosed by two radii and an arc and is given by the formula A = (θ/360)πr², where θ is the angle in degrees and r is the radius of the circle.
Here,
The area of a sector bounded by a 180° arc in a circle with a radius of 4 inches can be found using the formula;
A = (θ/360)πr²
Where θ is the angle in degrees and r is the radius.
Since the angle is 180°, we have:
A = (180/360)π(4²) = 8π square inches.
Thus, the area of a sector bounded by a 180° arc is 8π square inches.

The perimeter of the rectangle is 27n + 1 feet
Step-by-step explanation:
The formula of the perimeter of the rectangle is P = 2(L + W), where
L is the length of the rectangleW is the width of the rectangle∵ The width of a rectangle is 7n - 6.5 feet
∴ W = 7n - 6.5 feet
∵ The length of the rectangle is 6.5n + 7 feet
∴ L = 6.5n + 7 feet
→ Substitute W and L in the formula of the perimeter above
∵ P = 2[6.5n + 7 + 7n - 6.5]
→ Add the like terms
∴ P = 2[(6.5n + 7n) + (7 - 6.5)]
∴ P = 2[13.5n + 0.5]
→ Multiply the terms in the bracket by 2
∴ P = 27n + 1
∴ The perimeter of the rectangle is (27n + 1) feet
