1) y = 6
2) x = 3
3) y = - 2/3
4) x = - 6
Step-by-step explanation:So all we have to do is substitute the known 'variable' and solve for the unknown variable.
1) 2(-3) + 3y = 12
3y = 12 + 6
y = 6
2) 4y = (1/3)x - 5
4(-1) = (1/3)x - 5
(1/3)x = 5 - 4
x = 3
3) (x/3) - 2 = y
(4/3) - (6/3) = y
y = (-2/3)
4) 2(x+1) = 5y
2(x+1) = 5(-2)
2x + 2 = - 10
2x = -12
x = -6

Answers
Step by step:
For the sum : if you add 11 + 17 it gives you 28.
For the division: if you divided 28 by 3 it would equal 9.3.

Hello!
y=-1/3x+6
Perpendicular lines have slopes that are opposite reciprocals.
This means that if we have a slope of -1/3, its opposite reciprocal would be 3
Use Point-Slope form:
y-y1=m(x-x1)
y-4=3(x-2)
y-4=3x-6
y=3x-6+4
y=3x-2

Write the equation of the line in fully simplified slope intercept form
Answers
Answer:
y = x + 8
Step-by-step explanation:
It is y = 1/1x + 8, but we don't put the one if it's at the botton. So, y = 1x + 8, but, when a one is in front of the x, we don't put it either. The answer is
y = x + 8
The y-intercept is where the line "touches" the y-intercept, in this case, 8.
The slope is how many times you go up-down, and to side from point to pint, in this case 1/1.
Makes sense? If so, hope this helps!
Answer:
y = -1x + 8 or y = -x + 8 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
4 - 6 / 4 - 2 = -2/2 = -1
m = -1
b = y-intercept
b = 8
y = mx + b
y = -1x + 8
y = -x + 8

Pls help me with this question!!!
Answers
Step-by-step explanation:
just think a little bit.
congruent rectangles means they are all of equal size.
so, the sizes of all of these rectangles are 3×4.
therefore, the area of each one is 3×4 = 12 cm².
the total surface area (without the top
and bottom stars) is the sum of the areas of all rectangles.
how many rectangles are there ?
well, every "arm" of the star has 2 rectangle sides. and there are 5 "arms". so, there are 2×5 = 10 rectangles.
now it is really easy, right ?
we have 10 rectangles, each one with an area of 12 cm².
so the total surface area (without the star bases) is
12×10 = 120 cm²

What is the length of the missing side?
Answers
9514 1404 393
Answer:
10
Step-by-step explanation:
The Pythagorean theorem tells you the relationships of sides in a right triangle is ...
a² + b² = c² . . . . . . where 'a' and 'b' are the legs, and 'c' is the hypotenuse
6² +8² = c²
36 +64 = c² = 100
c = √100 = 10
The length of the hypotenuse is 10.
_____
Additional comment
The ratio of the leg lengths is 8/6 = 4/3. The only right triangle with legs in the ratio 4/3 has the relationship ...
hypotenuse : long leg : short leg = 5 : 4 : 3
If you multiply these numbers by 2, you see they correspond to the side lengths in this triangle. Your familiarity with a 3-4-5 right triangle can let you write down the answer immediately.
