Answer:
Step-by-step explanation:
Given the vectors based on the number line as RS = 7y +3, ST = 5y +8, and RT = 83, the equation RS+ST = RT will be used to get the unknown.
Substituting the given equation into the expression we will have;
7y +3+5y +8 = 83
collect like terms'
7y+5y+3+8 = 83
12y + 11 = 83
12y = 83-11
12y = 72
y = 72/12
y = 6
b) Substitute y = 6 into RS and ST
Given RS = 7y+3
RS = 7(6)+3
RS = 42+3
RS = 45
For ST;
ST = 5y+8
ST = 5(6)+8
ST = 30+8
ST = 38
Answer:
1/2 x 7/1 = 3 1/2 pieces of toast
Step-by-step explanation:
First part
Prob(Pink) = 18/50
this would be 22/50 = 44/100 = 44%
Answer:
Step-by-step explanation:
As we move from the point (2, 4) to the point (3, 6), x increases by 1 and y increases by 2. Thus the slope of the line connecting these two poins is m = rise/run = 2/1, or just 2.
Use the basic point-slope equation: y - k = m(x - h). Substitute 2 for x, 4 for y and 2 for m:
y - 4 = 2(x - 2). This is the desired equation in point slope form.
To find the equation in standard form, perform the multiplication as follows:
y - 4 = 2x - 4. We want this to look like Ax + By = C.
Thus, subtract 2x from both sides:
-2x + y = -4, or
2x - y = 4 This is the desired equation in Standard Form.
