Slope worksheet. Please help!!!

Answer:

x = 52

Step-by-step explanation:

This is a picture of a right angle, which is 90 degrees. We should first make an equation to represent this problem.

(x - 12) + 50 = 90

1. Subtract 50 from both sides of the equation.

(x - 12) = 40

2. Add 12 from both sides of the equation

x = 52

The value of x is 52.

Answer:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (8 - 1) / (5 - (-5))

          m = 7/10

y-intercept using slope above and anyone of given point. Let's use (-5, 1):

  y = mx + b

  1 = 7/10(-5) + b

  1 = -35/10 + b

  b = 45/10

  b = 9/2

Equation of line:

y = mx + b

y = 7/10x + 9/2

Point slope form:

y - y₁ = m(x - x₁)

y - 1 = 7/10(x - (-5))

y - 1 = 7/10(x + 5)

Answer:

40% (probability that an athlete is a football player OR a basketball player, but not both) I think this is what its asking, but the wording isn't super clear.

44% (probability an athlete is a football player, basketball player, or both)

Step-by-step explanation:

probability of only football player (21%-4%) plus probability of only basketball player (27-4%)

=17%+23%

=40%

Answer:

Answer:

There are 163 whiteboards undamaged.

Step-by-step explanation:

So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.

175 - 12 = 163.

There are 163 whiteboards undamaged.

163 white boards are undamaged

Given;

172 Students

25 in a pack

12 whiteboards are damaged

To Find;

How many whiteboards are undamaged?

Solution;

we need 172 whiteboard but one pack consist of 25 whiteboards

⇒ 172/25 = 6.88

≈ 7 pack

Total whiteboard we buy

⇒ 7 × 25 = 175

Out of which 12 whiteboard are damaged

↓ Undamaged whiteboard ↓

→ 175 - 12 = 163 ←

thus, 163 whiteboards are undamaged

The functions (f.g)(x) and (g.s)(x) are illustrations of composite function

The values of the composite functions are:

(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10

The equation of the functions are given as:

f(x) = 3x - 8

g(x) = -2x + 5

s(x) = 4x^2 - 9x + 2

.

The composite functions are calculated using:

(fg)(x) = f(x) * g(x)

So, we have:

(f g)(x) = (3x - 8) * (-2x + 5)

Evaluate the product

(fg)(x) = -6x^2 + 15x + 16x - 40

Evaluate the like terms

(fg)(x) = -6x^2 + 31x - 40

Also, we have:

(gs)(x) = g(x) * s(x)

So, we have:

(gs)(x) = (-2x + 5) * (4x^2 - 9x + 2)

Expand

(gs)(x) = -8x^3 + 18x^2 -4x + 20x^2 - 45x + 10

Collect like terms

(gs)(x) = -8x^3 + 18x^2 + 20x^2-4x - 45x + 10

Evaluate the like terms

(gs)(x) = -8x^3 + 38x^2 -49x+ 10

Hence, the values of the composite functions are:

(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10

Hi! I hope you're enjoying your day!

Here's how we classify polynomials:

More Information:

A polynomial with 1 term is called a monomial (for example, 6d)

A polynomial with 2 terms is called a binomial (for example, 6d+ 2a)

A polynomial with 3 terms is called a trinomial (for example, 6d+2a-4s)

A polynomial with 4 or more terms is called a polynomial

(for example. 6d+2a-4s+3e-t+9k-12a)

Degree: first, second, third.. depends on the exponent.

Hence, -2 is

Step-by-step explanation:

You divide the number of cups by 16 to find how many gallons are there in a certain amount of cups.

 Area of triangle = 1/2 x base x height:

78 = 1/2 x base x 9 3/4

Multiply both sides by 2:

156 = base x 9 3/4

Divide both sides by 9 3/4:

Answer:

Example

[tex]3\frac23-1\frac45[/tex]

convert to improper fractions:

[tex]\dfrac{3 \times 3+2}{3}-\dfrac{1 \times 5+4}{5}=\dfrac{11}{3}-\dfrac{9}{5}[/tex]

common denominator = 3 × 5 = 15, so:

[tex]\dfrac{11}{3}-\dfrac{9}{5}=\dfrac{11\times 5}{3\times 5}-\dfrac{9\times 3}{5\times 3}=\dfrac{55}{15}-\dfrac{27}{15}[/tex]

subtract:

[tex]\dfrac{55}{15}-\dfrac{27}{15}=\dfrac{55-27}{15}=\dfrac{28}{15}[/tex]

convert back to mixed fractions:
