Answer:

maby option 5

Step-by-step explanation:

Answer:

D. 73.6 ft^2

Step-by-step explanation:

Using trigonometry to get our answer: (we can use SAS to find the area)

A = 0.5 * side a (10ft) * side b (16ft) * sin(67)

A = 80 ft * sin(67)

A = 73.64 ft

Answer:

slope = [tex]\frac{6}{5}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{6}{5}[/tex] x - 4 ← is in slope- intercept form

with slope m = [tex]\frac{6}{5}[/tex]

Answer:

6/5

Step-by-step explanation:

this equation is already in the slope intercept form, meaning the slope (gradient)is the coefficient of x( the number before x). in this case it's 6/5.

The expression that represents the amount of money Deion would have saved in w weeks is 95 + 7w and the total savings after 6 weeks will be $137.

A statement expressing the equality of two mathematical expressions is known as an equation.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given,

Initial fixed money = $95

Per week saving $7/week

Total money = fixed money + money in w weeks.

⇒ 95 + 7w

For 6 weeks, w = 6

⇒ 95 + 7× 6 = $137.

Hence "The expression that represents the amount of money Deion would have saved in w weeks is 95 + 7w and the total savings after 6 weeks will be $137".

Answer:

The equation that represents this relation is [tex]y = 3x - 5[/tex].

The relation is a function.

If the domain of the relation is x > 2, the range of the relation is [tex]y >1[/tex]

Step-by-step explanation:

Given

Output = 3 * Input - 5

Required

Complete the gap

Solving (a):The equation for the relation.

Let

[tex]x \to[/tex] input

[tex]y \to[/tex] output

The relation is:

[tex]y = 3 * x - 5[/tex]

[tex]y = 3x - 5[/tex]

Solving (b): Is the relation, a function?

Yes; Because every value of x has a distinct value in 7

Solving (c): The range:

Domain: [tex]x > 2[/tex]

Substitute 2 for x in [tex]y = 3x - 5[/tex]

[tex]y =3 * 2 - 5[/tex]

[tex]y =6 - 5[/tex]

[tex]y =1[/tex]

The range is:

[tex]y >1[/tex]

Answer:

The equation that represents this relation is [ y= 3x - 5 ]

The relation [ is ] a function.

If the domain of the relation is x > 2, the range of the relation is y > [ 1 ].

Step-by-step explanation:

The output, y, of a relation, is the difference of three times the input, or 3x, and 5. So, y = 3x − 5.

Substituting any x-value from the domain into the equation will result in exactly one value of y, so the relation is a function.

To find the range of the relation, given the domain, substitute the boundary point of the domain into the function equation:

When x = 2, y = 3(2) − 5 = 6 − 5 = 1.

Because substituting values of x that are greater than 2 will result in values of y that are greater than 1, the range of the relation is y > 1.

Answer:

20

Step-by-step explanation:

Use the Pythagorean theorem. a^2+b^2=c^2

12^2+16^2=c^2

144+256=c^2

400=c^2

20=c

The number line that represents the solutions to Ix - 5| = 1 is the number line in the second option.

To solve absolute value equations like |x-5| = 1

We will write that

x - 5 = 1 and x -5 = -1

For the first equation

x - 5 = 1

Add 5 to both sides

x - 5 +5 = 1+5

∴ x = 6

For the second equation

x -5 = -1

Add 5 to both sides as well

x -5 +5 = -1 +5

∴ x = 4

Hence, x = 6 and x = 4

From the image, the second option is dotted (blue) at 4 and 6 on the number line.

Hence, the number line that represents the solutions to Ix - 5| = 1 is the number line in the second option

Answer:

x=21°

Step-by-step explanation:

Angle A = Angle B

Angle A = 45°

2x+3 =45°

To work out what x is, you would have to do inverse operations.

45-3=42°

2x=42°

42÷2=21° (We divide by 2 because, in algebra, whenever a number is next to a letter, it means times, so then we have to do the opposite and divide).

So, x=21°

Answer:

-8.

Step-by-step explanation:

x + 16 - 20 = 2x + 20 - 16

x - 4 = 2x + 4

x - 2x = 4 + 4

-x = 8

x = -8.

The mystery number 'm' that satisfies the stated conditions is - 8.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, The mystery number be 'm'.

So, When you add 16 to my mystery number then subtract 20,

m + 16 - 20,

you get the same result as when you add my mystery number to itself, then add 20 and subtract 16,

m + m + 20 - 16.

Therefore,

m + 16 - 20 = m + m + 20 - 16

m - 4 = 2m + 4.

- m = 8.

m = - 8.

Answer:

equation is y = 2-x

Step-by-step explanation:

x1 = -3

y1 = 5

x2 = 4

y2 = -2

now

m(slope) = rise/run =(y2-y1)/(x2-x1) =(-2-5)/(4+3) = -7/7 = -1

so m = -1

now

y =mx + b

-2 = -1×4 + b

or, -2 = -4 +b

so, b = 2

now

y = mx+b

y = -1x + 2

or, y = 2-x
