When simplifying an expression, you collect and simplify all the like terms. Since 8x and -12 aren’t like terms, you can’t substract 8-12
Answer:
19
Step-by-step explanation:
15+12-5+4-7=
(15+12+4)-5-7=
(27+4)-5-7=
31-5-7=
31-12=
19
Answer:
y=(x+2)(x+7)
Step-by-step explanation:
Answer:
The equation of the line would be y = -1/2x - 15
Step-by-step explanation:
To find the equation, we need to start by looking at the original equation's slope, which is 2. Perpendicular lines have opposite and reciprocal slopes, so the new line will have a slope of -1/2.
Now we use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 10 = -1/2(x + 50)
y - 10 = -1/2x - 25
y = -1/2x - 15
Answer:
6:3
Step-by-step explanation:
all others are a ratio of 3:1 when you simplify it except 6:3 which is 2:1 when simplified
