Answer:
slope = -1
Step-by-step explanation:
take the equation: y = mx + b for slope-intercept
y is the input
m is the slope
x is the output
b is the y-intercept
when the slope is -1, it is seen and implied as -x.

A TV has a length of 68 inches and a height of 51
inches. When TV's are advertised the size listed is the
diagonal length. What would be the advertised size of
this TV?
Answer:
85 inches
Step-by-step explanation:
Using pythag. A^2 + B^2 = C^2
(68*68) + (51*51) = 7225^2
Thus if you square root 7225, you get your answer - 85 inches.

Answer:
EBC and CBF are supplementary.
EBD=66
Step-by-step explanation:
Since vertical angles are congruent, ABE=CBF
ABE=40-x
40-x + 6x-30=90
5x+10=90
5x=80
x=16
16(6)-30=66

Pleaseee help answer correctly !!!!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!
Answer:
108º
Step-by-step explanation:
to find the sum of interior angles: ( n − 2 ) × 180 = x
x = 540º
n = # of interior angles
first, solve for n
(n - 2) • 180 = 540 distribute to 180 to (n - 2)
180n - 360 = 540 add 360 to both sides
180n = 900 divide both sides by 180
n = 5
to find measure of each angle:
540 ÷ 5 = 108º
A ramp has an angle of inclination of 20 degrees. it has a vertical height of 1.8 m. what is the length, l metres, of the ramp?
Answer:
x = 5.26 m
Step-by-step explanation:
Given that,
The angle of inclination = 20°
The vertical height of the ramp, h = 1.8 m
We need to find the length of the ramp. Let it is x.
We can find it using trigonometry. So,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
We have,
P = 1.8 m, H = x
[tex]\sin20=\dfrac{1.8}{x}\\\\x=\dfrac{1.8}{\sin20}\\\\x=5.26\ m[/tex]
So, the length of the ramp is 5.26 m.
At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41. The rate the Starbucks stock value was changing is - per hour
Answer:
1.50$
Step-by-step explanation:
difference in money amount: $6
difference in hours: 4
6 divided by 4 equals 1.50.
1.50 times 4 equals 6, hence its 1.50 per hour.
The rate of change in the Starbucks stock value is 150%.
Given that, At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41.
We need to find the rate the Starbucks stock value was changing is - per hour.
What is the rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now, the difference in money=41-35=$6
The number of hours between 10 AM to 2 PM is 4 hours.
The rate of change = The difference in money/Number of hours × 100
=6/4 × 100
=150%
Therefore, the rate of change in the Starbucks stock value is 150%.

Answer:
AC = 36
Step-by-step explanation:
since these triangles are similar, we can use the triangle similitary theorem. This means that the sides are proportional to each other.
ef/bc = 5/45 (1/9) = ed/ba = 2/18 (1/9)
we can see the sides are in a ratio of 1:9, and plug it in the proportion
df/ac = 1/9
4/ac = 1/9
cross multiply and we get that ac = 36

Answer:
[tex]x = 6[/tex]
Explanation:
Given:
[tex]Area = 24cm^2[/tex]
See attachment for shape

Find x
The attached shape is a rectangle.
So:
[tex]x * 4 = 24[/tex]
[tex]4x = 24[/tex]
Divide both sides by 4
[tex]\frac{4x}{4} = \frac{24}{4}[/tex]
[tex]x = \frac{24}{4}[/tex]

Please help!!!! The roots of x^2-2x-2=0 are A.1+square root of 3 B.1+square root of 12 or C.No real roots
Answer:
A
Step-by-step explanation:
We have the equation:
[tex]x^2-2x-2=0[/tex]
We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:
[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]
Simplify:
[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]
Hence:
[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]
Divide:
[tex]x=1\pm\sqrt3[/tex]
The correct answer is A.
Write the rule of the transformation
Answer:
(x + 5, y + 1)
Step-by-step explanation:
As we can see, what we have is a translation
let us pick a point
G( -5,-2)
To;
G’(0,-1)
so the shift on the x-axis is;
(0-(-5)) = 5
shift on the y-axis is;
(-1-(-2) = 1
we have a rightward shift of 5 units on the x-axis and 1 unit on the y-axis
So we have the rule as;
(x + 5, y + 1)

3² • 9³ = [ ]
solve
Answer:
3⁸ or 6561
Step-by-step explanation:
First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
There are no parentheses, so let's solve the exponents.
3² • 9³
3² = 9
9³ = 729
Your expression is:
9 • 729
Now let's multiply.
= 6561
This number can also be expressed with exponents.
Since 9 = 3², 9³ = 3²⁽³⁾
Now your expression is:
3² • 3²⁽³⁾
First, solve the exponents by multiplying.
3² • 3⁶
When you multiply two expressions with exponents that have the same base (3), you add the exponents.
3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸
3⁸ also equals 6561.
Your answer is 3⁸ or 6561.

y-intercept is graphed on a coordinate
plane. Which quadrant will the line not pass
through? Justify your response.
Answer:
The line will not pass through the first quadrant.
Step-by-step explanation:
Since the y-intercept is negative, and the slope is negative, the line will start in the second quadrant, pass through the third quadrant to intercept the y-axis, then pass through the fourth quadrant. It will never touch the first quadrant.

Find the length of side AB.
Give your answer to 1 decimal place.
CB = 12 cm
AB = 62°
PLEASE HELP!!
Answer:
AB ≈ 5.6 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )
12 × cos62° = AB , then
