The product is the answer you get from multiplying. The parentheses acts like a multiplication sign.
(–7)(–4)
–7 × –4 = 28
The answer is 28.
X = y + 1...so sub in y + 1 for x in the other equation
4x + 3y = -31
4(y + 1) + 3y = -31...distribute thru the parenthesis
4y + 4 + 3y = -31...subtract 4 from both sides
4y + 3y = -31 - 4....combine like terms
7y = - 35...divide both sides by 7
y = -35/7
y = - 5
now sub -5 in for y in either of the original equations to find x
x = y + 1
x = -5 + 1
x = -4
solution is (-4,-5)
There zeros of a function mean the x-intercepts. simpler way: At what x-values does the graph of the equation intersect the x-axis.
I don't know the if the last term of your function is +1 or -1 , so I did both for you using desmos graphing calculator.
You can also use quadratic formula, and do the algebra, and see if you get the same answer.
Answer:
line segments are the lines
rays are line segments that have one vertex
a vertex is the endpoint of a line(usually represented by a dot)
Step-by-step explanation:
Answer: For triangle: a line starting on the left corner going to the middle of the triangle. Hopefully that helps for the blank question
