Answer:
In BOLD.
Step-by-step explanation:
f(x) = (x - 1)(x + 7)
Convert to vertex form.
= x^2 + 6x - 7
= (x + 3)^2 - 9 - 7
= (x = 3)^2 - 16
So the vertex is at (-3, -16)
Also, as the vertex is a minimum the graph is increasing on interval x > -3.
From the graph we see:
The graph is positive on the interval
where x < -7 and x > 1.
- and negative where
-7 < x < 1.
I’m pretty sure the answer is b but not 100%
Answer =-0.7x +0
Find the gradient by y2-y1/x2-x1
-14 -7/ 20- -10
-21/30
-0.7
And plug in the coordinates to find the y intercept
7= -0.7 (-10) + c
C=0
The number terms in the given expression is 3, they are 5xy, -3x and -82.
The given expression is 5xy-3x-82.
<h3>What is an expression?</h3>
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
In the given expression 5xy-3x-82, there are three terms, which are 5xy, -3x and -82.
Therefore, the number terms in the given expression is 3, they are 5xy, -3x and -82.

Answer:
21.75
Step-by-step explanation:
If A onto B is 1 : 7.25 then you would do A times 7.25 to find the corresponding side. 3 times 7.25 is 21.75
