It's kinda like using variables, but shapes in their place. Let's set the circle to x, the triangle to y, and the square to z. Now the equations say x+(y+z)=13, (y+z)=8, and x+y=7. First thing we can do it plug 8 into the first equation for y+z, getting x+8=13. Subtract 8 to both sides and x (or circle) equals 5. Plug 5 into the last equation, x+y=7 to solve for y, getting 5+y=7. Subtract 5 to both sides and y (or triangle) equals 2. Finally, plug two in for y in y+z=8, getting 2+z=8. Subtract 2 from both sides and z (or square) equals 6. Hope I've explained it clearly!!
Answer:
The equation of line with slope 
and points ( - 1 , 3 ) is y = x + 
Step-by-step explanation:
Given equation of a line as :
y = x + 3
The line equation is in the form of y = m x + c
Where m is the slope of the line
Now while comparing given line equation with standard line equation ,
So , slope of the line m =
∵ Another line is passing through points ( - 1 , 3 ) , and is parallel to given line
Now <u>if two lines are parallel then slope of both lines are equal </u>
Let The slope of another line = M
So, M = m =
∴ The equation of line with slope and passing through points ( - 1 , 3 ) is
y - 
= M × ( x - 
)
Or, y - 3 = × ( x + 1 )
or, 4 × ( y - 3 ) = 5 × ( x + 1 )
Or, 4 y - 12 = 5 x + 5
Or, 4 y = 5 x + 17
∴ y = x +
Hence The equation of line with slope and points ( - 1 , 3 ) is y = x + Answer
Hola!
x = 7 , x = -7
Explicación:
Comienza restando 15 en cada lado:
Usted obtiene:
Ahora divide ambos lados por 2:
Usted obtiene:
Como la ecuación está al cuadrado, tendrás que hacer:
que te da: 
Entonces:
Remember that multiplying is how many times you add a number to itself. If you multiply by 3, you add the first number to itself 3 times.
When you multiply a given number by 1, you get the first number (it doesn't change).
When you multiply by a number less than one, say, one half, you'll end up with half of the original number --> a smaller number.
When you multiply a number by more than one, you will get a number bigger than the original because you are adding it to itself more than once. Even if it is a fraction or decimal, if it is greater than 1, then the new product will be larger than the original number.
Hope this helps! :)
