NO LINKS!! PLEASEE HELPP QUICK I POSTED THIS SO MANY TIMES AND NOBODY ANSWERS PLSSS HELP MEEE Write the slope-intercept inequality for the graph below. If necessary, use <=
fors or >= for >
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.
The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.
The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.
Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-
y ≤ -2x - 2

What’s the probability?
Answer:
[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
The probability for a flip on either side of the coin is always 50% or [tex]\frac{1}{2}[/tex]
So to get the probability for the three flips just do:
[tex](\frac{1}{2}) ^{3}[/tex] or [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex]
Either way you solve it the answer is [tex]\frac{1}{8}[/tex]

HELP PLEASE THANK YOU
Answer:
∠1 = 103°
Step-by-step explanation:
supplementary angle to 136° = 180° - 136° = 44°
∠1 = 180° - 33° - 44° = 103°
Step-by-step explanation:
Let the unnamed angle in the triangle be x.
x + 136 = 180 (Sum of angles on the same straight line)
x = 180 - 136
= 44
Angle 1 + x + 33 = 180 (Sum of angles in a triangle)
Angle 1 + 44 + 33 = 180
Angle 1 + 77 = 180
Angle 1 = 180 - 77
= 103

What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)
Question 1
Select ALL of the expressions below that represent the product of n and 7.
zn
n+7
7+n
You are drawing a map of your school and want to make sure all the measurements are accurate. You decide to use a scale of 1 cm = 3 feet. In your drawing, the main hallway ends up being 12 cm long.
The drawing is a little too big so you decide to change the scale to 1 cm = 4 feet.
Keeping the length in feet the same, how many centimeters long should the main hallway be in your new drawing?
Answer:
the main hallway should be 12cm in the new drawing
Step-by-step explanation:
The two legs of a right triangle measure 7 inches and 5 inches. Find the measure of the acute angle that is included between the longer leg and the hypotenuse. WILL GIVE BRAINIEST TO FIRST RIGHT ANSWER
Answer:
44.4 degrees
Step-by-step explanation:
Given the following
Hypotenuse = 7
Longer leg = 5 (adjacent])
Let the acute angle angle between both sides be x
According to SOH CAH TOA
Cos theta = adj/hyp
Cos x = 5/7
x= arccos (5/7)
x = arccos (0.7143)
x = 44.4degrees
Hence he measure of the acute angle that is included between the longer leg and the hypotenuse is 44.4 degrees
A man started a journey at 09:30 h and arrived at his destination in the same time zone, at 13:30 h on the same day. If his average speed was 30km/h, then the distance, in km, for the journey was
Answer:
120km
Step-by-step explanation:
We multiply 30km (thats how fast he was moving per hour) by the number of total hours during the journey, which is 4, 30 x 4 is 120km.
After applying the distributive property to the expression 8(12-4) and then multiplying what will be the first term in the resulting subtraction expression
Answer:
The first term in the resulting subtraction expression is 96.
Step-by-step explanation:
Given - After applying the distributive property to the expression 8(12-4) and then multiplying
To find - What will be the first term in the resulting subtraction expression ?
Proof -
Given the expression is -
8( 12 - 4) = 8(12) - 8(4)
= 96 - 32
⇒8( 12 - 4) = 96 - 32
So,
The first term in the resulting subtraction expression is 96.
I need help plz. Can anyone help me ASAP?
Answer:
6 + 4d + 11c
Step-by-step explanation:
In order to find the perimeter, you add up all the side lengths which would be expressions in this case
(10c + 10) + (c + 5) + (4d - 9)
add like terms: (10c + c) + (10 + 5 - 9) +4d
= 11c + 6 + 4d
which is the same as 6 + 4d + 11c, I just added them in a different order.
What is the answer to c to the fifth power, times c to the eighth power, times c to the negative fifth power?
Answer:
c^8
Step-by-step explanation:
Expressing the above Mathematically ;
c^5 * c^8 * c^-5
From.rules of indices :
a^x * a^y = a^(x + y)
Therefore, applying the rule of indices ;
c^5 * c^8 * c^-5 = c^(5 + 8 + - 5)
c^5 * c^8 * c^-5 = c^(5 + 8 - 5)
c^5 * c^8 * c^-5 = c^8
Hence,
c^5 * c^8 * c^-5 = c^8

A cat can eat 1/4 of a bag of food in 1/2 of a week. How much food can the cat eat in 1 week
Answer:
1/2 of a bag in a full week
Step-by-step explanation:
If they can eat a fourth of a bag and a half of a week then they can eat a half of a bag and a full week because to have is 1/4+1/4 which equals 1/2

Answer:
7u -63
Step-by-step explanation:
The distributive property says you can eliminate parentheses by applying the outside factor to each term inside parentheses.
(u -9)7 = (u)(7) +(-9)(7) = 7u -63
Answer:
(u -9)7 = (u)(7) +(-9)(7) = 7u -63
An architect is constructing a model in the shape of a triangle that has one side length of 9 centimeters and another side length of 8 centimeters. Which
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Sides:\ 9cm\ and\ 8cm[/tex]
The question is incomplete, as what is required is not state. However, a possible question could be to determine the possible side length of the third side.
To do this, we make use of the triangle inequality theorem which states that:
Given three sides (a, b and c) of a triangle, the following inequalities exist.
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
Let a and b represent the two sides such that:
[tex]a = 9[/tex]
[tex]b = 8[/tex]
The inequalities become:
[tex]9 + 8 > c[/tex]
[tex]9 + c > 8[/tex]
[tex]8 + c > 9[/tex]
Solve for c in each:
[tex]9 + 8 > c[/tex]
[tex]17 > c[/tex]
[tex]c < 17[/tex]
[tex]9 + c > 8[/tex]
[tex]c > 8 - 9[/tex]
[tex]c > - 1[/tex]
[tex]8 + c > 9[/tex]
[tex]c >9 - 8[/tex]
[tex]c >1[/tex]
The value of c must be positive, so, we consider;
[tex]c >1[/tex] and [tex]c < 17[/tex]
Rewrite:
[tex]1 < c[/tex] and [tex]c < 17[/tex]
Combine both
[tex]1 < c < 17[/tex]
Hence, the value of c is:
[tex]c = (1,17)[/tex]
Calculate the area of the shape below:
6 in
6 in
12 in
O 54 in?
0 432 in?
O 216 in
O 108 in?
Answer:
54
Step-by-step explanation:
The square in the middle = 36, as 6x6=36
There are 2 triangles on each side of the center square.
Since the base of the trapezoid is 12, and the base of the square is 6, that leaves 3 for the base of each triangle.
3x6=18x1/2 (As a triangle's area is b (base) x h (height) x (one half) 1/2
18x1/2 is 9.
Each triangle equals 9.
36+9+9=54
The final answer is 54
