Answer:
a) x^2 + y^2
b) 9-xy
Step-by-step explanation:
Here, we want to write the algebraic statements as expressions;
a) The sum of the squares of x and y
The square of x is x^2
The square of y is y^2
The sum of the squares is x^2 + y^2
ii) Product of x and y subtracted from 9
The product of x and y is x * y = xy
Subtracting these from 9, we have;
9-xy
Answer:
f(2)= 11
Step-by-step explanation:
you have to substitute 2 for every x you see:
f(x) = 3x² + 2x - 5
f(2)= 3(2)^2+2(2)-5
f(2)= 11
Answer:
115
idk how to explain this but u just use the protractor
Answer:
Option (C)
Step-by-step explanation:
Given inequalities are,
81 > x and x > 68
Therefore, 81 > x > 68 is the inequality representing the solution area for x.
Out of x = 88, 85 and 80,
x = 80 will lie between the range of x = 68 and x = 81.
Therefore, Option (C) will be the correct option.
120
times 12 - 360
it should give you the right answer if you solve the problem like that
