-2x+10
plug in x=3
-2(3)+10
-6+10
4
The answer is 4
5x-10+6 (then you sum the like terms)
5x-4
the answer is B 5x-4

9. Raymond and Rose were working with exponents.
Part A: Raymond claims that 55 * 52 = 53. Rose argues that 55 * 52 = 57. Which one of
them is correct? Use the properties of exponents to justify your answer.
Part B: Raymond claims that 79/75 = 74. Rose argues that 79/75=745. Which one of
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =1 and y_1 =2
m the slope m= -2 (same slope for the line : 2x+y-1=0 because this lines are parallel and you can write y=-2x-1
an equation for this line is : y-2 = -2(x-1)
Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the center (0, 3) and the point (-1.5, 3) on the circumference.
The radius is a distance between given points: r = 1.5.
Substitute:
