Answer:
ez
Step-by-step explanation:
start at the point you were given, and use the slope. remember rise over run.
There is no one answer (ordered pair) to this equation and the answer is found by graphing or trying out different values for each variable. Anyway, here are some solutions; (1,0), (4,1), (0,-1/3).
Answer:
Two times of your age = 16 × 2 = 32
So, 200 reduced = 32 - 200 =<u> - 163 </u><u>years</u>

Answer:
1.) k = 5
2.) n = -20
3.) p = -13
4.) m = -450
5.) b = -38
6.) n = -24
7.) x = 21
8.) x = 12
9.) b = -2
10.) b = 5
Step-by-step explanation:
To solve all equations, do the reciprocal, or opposite of what is being done. For example, if a number and a variable are being multiplied, you would divide by the number to solve.
1.) 55 = 11k
(11 and k are being multiplied, so you would divide)
Divide by 11 on both sides:
55 = 11k
/11 /11
5 = k
2.) Add 15 on both sides:
n - 15 = -35
+15 +15
n = -20
3.) Divide by -6 on both sides:
78 = -6p
/-6 /-6
-13 = p
4.) Multiply by 18 on both sides:
m/18 = -25
18(m/18) = (-25)18
m = -450
5.) Add 20 on both sides:
18 = -20 - b
+20 +20
38 = -b
Divide by -1 on both sides:
38 = -b
/-1 /-1
-38 = b
6.) Subtract 12 on both sides:
12 + n/4 = 6
-12 -12
n/4 = -6
Multiply by 4 on both sides:
4(n/4) = (-6)4
n = -24
7.) Multiply by 2 on both sides:
2(-7 + x/2) = (7)2
-7 + x = 14
Add 7 on both sides:
-7 + x = 14
+7 +7
x = 21
8.) Subtract 2 on both sides:
-4x + 2 = -22
-2 -2
-4x = -24
Divide by -4 on both sides:
-4x = -24
/-4 /-4
x = 12
9.) Add 9 on both sides:
7 = -8b - 9
+9 +9
16 = -8b
Divide by -8 on both sides:
16 = -8b
/-8 /-8
-2 = b
10.) Multiply by -3 on both sides:
-3(b - 14/-3) = (3)-3
b - 14 = -9
Add 14 on both sides:
b - 14 = -9
+14 +14
b = 5
Answer:
i) it is not possible for the student to receive an A in the class
ii) 119 points
iii) 84points
Step-by-step explanation:
Total exam scores = 350points
homework scores of 7, 8, 7, 5, and 8
Let the third exam score =y
Exam scores = 81, 80, x
i) To know if the student would get an A in class, we would find the third exam score
(Scores received by a student)/ (total scores) = least of the grade percentage to get an A
(7 + 8 + 7 +5 + 8 + 81 + 80 + x)/350 = 0.9
(196+x)/350 = 0.9
196+x = 350 × 0.9
196+x = 315
x = 315-196
x = 119
119 > 100
Since the maximum grade for each of the exam score is 100points, it is not possible for the student to receive an A in the class.
ii) Since the least of the grade percentage that would guarantee an A is 0.9, the minimum score on the third exam that will give an A = 119points
iii) (Scores received by a student)/ (total scores) = least of the grade percentage to get a B
(7 + 8 + 7 +5 + 8 + 81 + 80 + x)/350 = 0.8
(196+x)/350 = 0.8
196+x = 350 × 0.8 = 280
x = 280-196
x = 84
The minimum score on the third exam that will give a B = 84points
