Answer:
m<DAE = 80°
Step-by-step explanation:
Given that m<CAB = 110°,
m<DAE = (x + 4)°,
m<EAF = 30°,
m<EAF + m<DAE = m<DAF (angle addition postulate)
30° + (x + 4)° = m<DAF (substitution)
(34 + x)° = m<DAF
<DAF and <CAB are vertically opposite angles. Vertically opposite angles are said to be congruent. Therefore:
m<DAF = m<CAB
(34 + x)° = 110° (substitution)
The equation above can be used to solve for x as follows:
34 + x = 110
x = 110 - 34 (Subtracting 34 from both sides)
x = 76
m<DAE = (x + 4)°
Plug in 76, to replace x
m<DAE = 76 + 4
m<DAE = 80°

The missing side of the triangle is measure 13 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Two sides of right triangle are,
⇒ 5 cm, 12 cm
Since, The triangle is a right triangle.
So, We can apply the Pythagoras theorem as;
Let the measure of missing side = x
⇒ x² = 5² + 12²
⇒ x² = 25 + 144
⇒ x² = 169
⇒ x = √169
⇒ x = 13 cm

Answer:
x = ±√17
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other.
Also note that the x has a power of 2. To isolate the x, simply root both sides of the equation.
x² = 17 ; √x² = √17 ; x = ±√17

Which function is most likely graphed on the coordinate plane below? f(x) = 3x – 11 f(x) = –4x + 12 f(x) = 4x + 13 f(x) = –5x – 19
Answer:
D
Step-by-step explanation:
It's D on Enginuity
The graph of the function in the coordinate plane is f(x) = –5x – 19.
What is a Graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.
As per the given diagram:
The x intercept of the line = -ve
The y intercept of the line = -ve
For f(x) = 3x - 11
x intercept = +ve
y intercept = -ve
Hence, not possible
For f(x) = -4x + 12
x intercept = +ve
y intercept = +ve
Hence, not possible
For f(x) = 4x + 13
x intercept = -ve
y intercept = +ve
Hence, not possible
For f(x) = -5x - 19
x intercept = -ve
y intercept = -ve
Hence, possible
The function plotted on the coordinate plane is f(x) = –5x – 19.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the expression √(45)
⇒ √(9×5)
⇒ √(3²×5)
⇒ √(3²)√(5)
Since the square root of a square is the same number
So,
⇒ 3√5
Hence "The expression 3√5 will be equivalent to a square root of 45".

Talia has a square framed moving box with an area of 16 square feet. The cube shaped box has a volume of 66 cubic feet. Will the poster lie flat in the box?
Answer:
4,4,64,larger,larger,would
Step-by-step explanation:
Begin by finding the dimensions of the poster. Since it is in the shape of a square, each edge will be the same length. and 16 divided by 4 is 4 and then you do 16 x 4 you get 64 and then you know is the box larger or not in this case the box is larger.
Find the inverse of the following function g(x) = 2x+10/4
Answer:
Step-by-step explanation:
To find the inverse of the function you need to swap x and y
g(x)=y so therefore if you switch x and y, you get
x= 2y+ 10/4
Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.
x-10/4=2y+10/4-10/4
The end product of this should be... (This is not your answer)
x-10/4=2y
Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2
2/x-10/4=2y/2
So your answer is...
x-10/4 over 2 = y
OR
2/x + 5/4 = y

3(-X+4)=7x-8. Yeahhhh...
Hey there!☺
[tex]Answer:\boxed{x=2}[/tex]
[tex]Explanation:[/tex]
[tex]3(-x+4)=7x-8[/tex]
Let's start by simplifying both sides. First, we distribute.
[tex](3)(-x)+(3)(4)=7x+-8[/tex]
[tex]-3x+12=7x+-8[/tex]
[tex]-3x+12=7x-8[/tex]
Now let's subtract 7x from both sides.
[tex]-3x+12-7x=7x-8-7x\\-10x+12=-8[/tex]
Now we will subtract 12 from both sides.
[tex]-10x+12-12=-8-12\\-10x=-20[/tex]
In our last/final step, we will divide both sides by -10.
[tex]\frac{-10x}{-10}=\frac{-20}{-10}[/tex]
Now simplify -20/-10.
[tex]-20/-10=2[/tex]
[tex]x=2[/tex]

I assume we're solving for n.
3n/7 - 1 = 1/8.
First, add 1 to both sides.
3n/7 = 9/8
Now, let's multiply both sides by 7
3n = 63/8
Divide both sides by 3
n = 21/8
