Answer:
-58
Step-by-step explanation:
We are to find tfhe dot product of u=<-8,9> and v=<5,-2>
u*v = <-8,9>*<5,-2>
u*v = -8(5)+9(-2)
u*v = -40 - 18
u*v = -58
Hence the product of the vectors is -58
The solution to the inequality is x > 2.
Step-by-step explanation:
According to given statement;
The inequality is;
Solving the inequality;
Adding 1/3 on both sides
Multiplying both sides by
Therefore;
The solution to the inequality is x > 2.
The equation is
y = -(6/7)*x + 9
We just need to evaluate the function in x = 21
This means
y = -6*21/7 +9 = -6*3 +9 = -18 +9 = -9
(x,y) = (21,-9)
The second one or y = 7.50x
That is because the four pounds of almonds divided by thirty dollars is 7.50. So if you were to add one more pound of almonds, you would have to pay $7.50 more.

Step-by-step explanation:
Translation right 6 units adds 6 to every x-coordinate. Rotation 90° CW is the transformation (x, y) ⇒ (y, -x). The sequence of transformations gives ...
(x, y) ⇒ (y, -x-6)
Then the coordinates of the transformed figure are ...
P(-3, 7) ⇒ P'(7, -3)
Q(4, 12) ⇒ Q'(12, -10)
R(4, -2) ⇒ R'(-2, -10)
S(-3, -7) ⇒ S'(-7, -3)
