Answer:
1) Word Problem
Sally has $2 and her mother gave her $10 to buy something from the store. Sally spent $7 at the store. How much money does Sally have now?
Expression
(2 + 10) - 7
2) Word Problem
Bob has 5 friends and each of them gave Bob 2 cookies. Bob originally had 2 of his own cookies. After collecting all of the cookies Bob split them evenly among him and his friends. How many cookies does each person have?
Expression
(5 x 2 + 2) ÷ 6
Answer:
Step-by-step explanation:
By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:
7y + 4y - 15 + 4y - 15 = 180 and
15y - 30 = 180 and
15y = 210 so
y = 14. Plug 14 in for y in 7y and get that
∠N = 98°
Answer:
g(1) is larger
Step-by-step explanation:
Given
See attachment for graph
Required
Determine which is larger; f(1) or g(1)
From the attachment, the red curve represents f(x) while the blue curve represents g(x)
Next, we determine the values of f(1) and g(1).
f(1) is the point where x = 1 on the y-axis (for the red curve)
So:
g(1) is the point where x = 1 on the y-axis (for the blue curve)
So:
By comparison:
<em>So, g(1) is larger</em>
To get the slope, we will need two points that belong to the line.
From the graph, we can get two points as follows:
(0,-1) and (-1,1)
The slope of the curve can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
Substitute with the two points to get the slope as follows:
slope = (1--1) / (-1-0) = (2) / (-1) = -2
