1/2 is the same as .5 and 4 is a whole number, so the decimal form would be 4.5
Answer:
x² + x + 8 = 0
Step-by-step explanation:
Given
(x - 2)² + 5(x + 2) - 6 = 0 ← expand (x - 2)² and distribute parenthesis by 5
x² - 4x + 4 + 5x + 10 - 6 = 0 ← collect like terms on left side
x² + x + 8 = 0 ← equivalent quadratic equation
Answer:
m = -2
Step-by-step explanation:
To get the slope of the line, we are going to use the 2-points slope equation form
That will be;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-5,11)
(x2,y2) = (8,-15)
m = (-15-11)/(8-(-5)) = -26/13 = -2
The possible mistake she might have made is placing the x-values difference over the y and her formula will look like;
m = (x2-x1)/(y2-y1)
It is an error of switching the numerator for the denominator
Answer:
Step-by-step explanation:
Second option correct
Answer:
B, B, A.
Step-by-step explanation:
5x means 5 multiplied by x, so is it A, B or C? the product, because that means multiplied. a is B.
For b, we can see that 7 is a constant, because it isn't being multiplied by anything.
For c, 2y is 2 multiplied by y. Y would be the variable, and 2 would be the coefficient.
