5-5r
-5 and 10 have like terms, so you can add them
they make positive 5
(-5r) is just -5r, and you can't add it to a number without a variable
so the answer is 5-5r
slope of line(m) = 2 and intercept on y axis is -2 that is 2 unit in negative y axis.
Equation of line in slope intercept form:
Slope:
Slope is known as tangent of an angle made by positive X-axis.
We know equation of line in slope and intercept form is,
y = mx + b
where,
m is slope of line
b is intercept on y axis
hence for the given equation,
y =2x - 3
slope (m) will be = 2
intercept on y axis (b) = -3
thus,
option (B) will be correct.

Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
For something to float the buoyant force ( force pushing up on the object to keep it floating) needs to equal the weight of the object
the answer would be: <span>weight of the ball</span>
This is g composed of f of x where we first find f(x) then plug that into g(x)
g(f(-1))
g(2 * -1 + 3)
g(1)
