Answer:
x=2 y=-4
Step-by-step explanation:
-2x=y
-x-6x=-14
-7x=-14
x=2
Answer:
first figure: y=70
second figure: Guessing that that number is 99, x=99, y=99, z=81
third figure: x=180-48-77=55 x=55
Step-by-step explanation:
Y - 5x = 10 can be written in the slope-intercept form as
y = 5x + 10
The slope-intercept form is y = mx + b, where m = slope, and b = y-intercept.
In this case, the 5 is the slope.
Parallel lines have equal slopes, so the line we need to find also has a slope of 5. Its equation is
y = 5x + b
We need to find what b is.
We can use the given point, (3, 10), in for x and y and solve for b.
10 = 5 * 3 + b
10 = 15 + b
-5 = b
Now that we know that b = -5, we replace b with -5 to get our equation
y = 5x - 5
Answer:
When an equation is in standard form, the y-intercept could be given by C/B.
Step-by-step explanation:
In order to find the equation, we start with the base equation of standard for and then solve for slope intercept form.
Ax + By = C
By = Ax + C
y = A/Bx + C/B
And this shows us that C/B is the y-intercept
If you're asking us to solve for Z...
z² + 11z = -21/4
4z² + 44z + 21 = 0
Enter... *drumroll* the quadratic equation!
(that's a plus or minus, sorry)
x = -0.5 or -10.5
Does this help? Is it too complicated? Do you have any questions?
