Find the product.
(x-3)(x+5)
Answer:
x2+5x-3x-15=x2+2x-15
Step-by-step explanation:
(x)(x)=x2,(x)(5)=5x
(-3)(x)=-3x,(-3)(5)=-15
Answer: X^2 + 8x -15
Step-by-step explanation:
Use the foil method.
First, outer, inner, last
Multiply the first numbers inside each parenthesis. X*X = x^2
Next multiply the outer number in each parenthesis. X*5 = 5x
Then multiply the inner numbers of the parenthesis. -3*x= 3x
Finally multiply the last numbers in the parenthesis. -3*5 = -15
Now add all of these together
X^2 + 5x + 3x + -15
Combine like terms
X^2 + 8x -15
X can be solved from here, however it does not seem that you are asked to solve for x
What are the x- and y-intercepts?
0,3
1,20
3,36
5,28
7,0
The required x-intercept is (7, 0) and the y-intercept is (0, 3).
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.
The x-intercept is therefore (7, 0).
To find the y-intercept, we need to find the point at which the graph intersects the y-axis. This occurs when the x-coordinate is zero.
The x-intercept is therefore (0, 3).
Thus, the x-intercept is (7, 0) and the y-intercept is (0, 3).

2/3(x+6)=-8 whats the value of x?
Answer:
x=-18
Step-by-step explanation:
Answer:
The answer is -18
Step-by-step explanation:
STEP 1:
[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]
2(x+6) = -24
______________________________________
STEP 2:
Divide both sides by 2:
[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]
________________________________
STEP 3:
Simplify:
[tex]x + 6 = - 12[/tex]
Subtract 6 from both sides:
[tex]x + 6 - 6 = - 12 - 6[/tex]
________________________________
STEP 4:
[tex]x = - 18[/tex]
Therefore, your answer is -18.
