16-8=8
Step-by-step explanation:
Which equation could best be used to determine the value
of f(3) for the function f(x) = 2x + 4?
1) f(3) = 23+ 4
2) f(3) = 2(3)+4
3) f(3) = 3(2x) + 4
4) f(3) = 3(2x + 4)
Answer:
2) f(3) = 2(3)+4

Write down the integer value of x that satisfies 16 < 3x < 20
Answer:
x must be 6 because 6 * 3 is 18 which is greater than 16 but less than 20. x can't be 6.1 or include decimals or fractions because integers are whole numbers just adding negative numbers so therefore 6 is the only answer for this question.

an investor owns shares of stock a and stock b. the investor owns a total of 200 shares with a total value of $4000. How many shares of each stock does the investor own?
Answer:
a = 80 shares of stock A
b =120 shares of stock B
Step-by-step explanation:
Solved by creating a system of equations
Let a be number of shares of stock A
B number of shares of stock B
a + b = 200
9.5a + 27b = 4000
Solving the two equation
a = 80 shares of stock A
b =120 shares of stock B

Okay?!Write the line (-5,-6) with slope 2/5 in point-slope form
Answer:
[tex]y+6=\frac{2}{5} (x+5).[/tex]
Step-by-step explanation:
1) the common form of the point-slope form is y-y₁=s(x-x₁), where s - the slope, (x₁;y₁) - the point belongs to the required line;
2) if s=2.5; x₁= -5; y₁= -6, then the required equation is:
y+6=2/5(x+5).

28 (money) / 4 (shirt cost) = 7 (shirts)
Assuming no tax and stuff, Maria should be able to by 7 shirts on top of her other items.

if there are 139,799,000 square miles of water on earth what percent is left on earth that is not covered in water
The percentage of earth that is not covered in water is given by the equation A = 29 %
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total area of earth be = 196,900,000 square miles
And , 71% of Earth’s surface is covered in water
So ,
Percentage of earth's surface covered in water = 71 %
And , area of earth covered by water = 139,799,000 square miles
Substituting the values in the equation , we get
So , the remaining percentage of earth not covered in water A = 100 - 71
On simplifying the equation , we get
Remaining percentage of earth not covered in water A = 29 %
The remaining area of earth = 0.29 x 196,900,000
The remaining area of earth = 57,101,000 miles²
Therefore , the value of A is 29 %
Hence , the percentage is 29 %

Option 2. Both lines have the same slope but start at a different y-intercept so they would be parallel. The other choices are false as well.
Please help me. I'm struggling with my math
Answer:
a. (4, -3)
b. (-2.5, -4)
Step-by-step explanation:
a. 2x - 4y = 20
x = 4
step 1: plug in x value
2(4) - 4y = 20
8 - 4y = 20
Subtract 8 on both sides
-4y = 12
divide both sides by -4
y = -3
b. y = 6x + 11
2x - 3y = 7
step 1: plug in the y value
2x - 3(6x + 11) = 7
step 2: distribute
2x - 18x - 33 = 7
add 33 from both sides and combine like terms
-16x = 40
divide both sides by -16
x = -2.5
Okay now you plug in the x value to solve for y
y = 6(-2.5) + 11
y =-4
