Answer:
The answer is (1,-9)
Step-by-step explanation:
First, you have to plug -9x to y because y = -9x. Then multiply
-6(-9x) = 54x
-8x + 54x = 46
46x = 46
x = 1
Plug 1 into the first equation to find the value of y.
y = -9(1)
y= -9
Answer:
Scale Factor is: When you divide the old shape by the new shape (explanation is here)
Step-by-step explanation:
When you have 2 shapes (lets say Y is the old shape and F is the new shape) you would divide the old shape (Y) by the new shape (F)
Another example: lets say shape F is 12 cm and shape Y is 7 cm (F being the old and Y being the new shape) you would divide 12 and 7 to get the answer to that problem
If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).
<h3>What is a quadratic equation?</h3>
It's a polynomial with a worth of nothing.
There exist polynomials of variable power 2, 1, and 0 terms.
A quadratic condition is a condition with one explanation where the degree of the equation is 2.
Domain and range of linear and quadratic functions
Let the linear equation be y = mx + c.
Then the domain and the range of the linear function are always real.
Let the quadratic equation will be in vertex form.
y = a(x - h)² + k
Then the domain of the quadratic function will be real.
If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).
