Answer:
x=√16
Step-by-step explanation:
-3x^2=48
First, we divide by -3 on both sides of the equation.
x^2=16
Then we find the square root of both sides.
x=√16
Answer:
1.72
Step-by-step explanation:
AB tangent at D, AD = OD = 4
so triangle OAD is right angle with side of 4 and 4.
area of OAD = 1/2 * 4 * 4 = 8
Angle AOD = DAO = 45 deg.
so circular sector OCD area = area of circle O * 45/360
= pi * 4 * 4 * 45/360
= 2pi
Shade area ACD = trigangle OAD - circular sector OCD
= 8 - 2pi
= 1.72

Answer:
B) y + 7 = 5x
Step-by-step explanation:
In math, a linear function is one that has a graph that is a line. It looks like this: There are two things that make up the equation: y = f(x) = a + bx. One independent variable and one dependent variable make up a linear function, which is also called a simple function. The independent variable is x, and the dependent variable is y, which is what you're interested in. Also, there are no exponents in a linear function, which means the exponent is one.
Answer:
y = -x^2 − 2.5x + 350
Step-by-step explanation:
y = (10 + 0.5x)(35 − 2x)
y = 350 − 20x + 17.5x − x^2
y = 350 − 2.5x − x^2
