Answer:
The x-intercept=7
Step-by-step explanation:
Step 1
Given the equation;
y=-x+7, is a linear equation
Step 2
The x-intercept is the value of x when the graph crosses the x-axis. At this point, the value of y=0
Step 3
Substitute the value of y in the linear equation above to solve for the x-intercept.
Given;
y=0
And the linear equation is;
y=-x+7
replace;
0=-x+7
x=7
The x-intercept=7
Y<-8 because the number y is no less

Answer:
cubic polynomial
Step-by-step explanation:
Given polynomial is ![\[h(x)=-6x^{3}+2x-5\]](https://tex.z-dn.net/?f=%5C%5Bh%28x%29%3D-6x%5E%7B3%7D%2B2x-5%5C%5D)
A polynomial of degree 1 is a linear polynomial.
A polynomial of degree 2 is a quadratic polynomial.
A polynomial of degree 3 is a cubic polynomial.
In this case the exponent with the maximum value in the polynomial is 3.
Hence the degree of the polynomial h(x) is 3.
Hence the given polynomial is a cubic polynomial.
It is the first one I believe
