X=28
Step-by-step explanation:
Answer:
28
Step-by-step explanation:
A triangle always has 180° so that means 40° (2x+9)° and another angle add up to 180°.
We can find out two angles in order to find out the third, one of them is 40° the other is 180°-105° because there are 180° on a line.
you get 75.
75°+40°=115°
180°-115°=65°
2x+9=65°
Make x the subject of the formula:
2x=56
(take away 9)
x=28
(divide both sides by 2)

Find the value of x.
Answers
Answer:
A or B
Step-by-step explanation:
The value of x is 38
First, you must subtract 180 by 105 to get the bottom left corner measurement.
[tex]180-105=75[/tex]
Then, you must add the two measurements you and subtract from 180 to find x
[tex]75+67=142[/tex]
[tex]180-142=38[/tex]

Simple interest = ?
solution,
simple interest = PTR/100
= Rs.1200*2*5/100
= Rs.12000/100
= Rs.120
Therefore,the simple interest is Rs.120.

Which of the following is the measure of the largest angle in the triangle shown?
Answers
19x + 7x + 10x = 180°
36x = 180
x = 5°
largest angle = 19 * 5 = 95°
Answer:
C. 95°
Step-by-step explanation:
19x+ 7x +10x = 180 (sum of the interior angles of a triangle is 180)
36x = 180
x= 180÷36
x= 5
Magnitude of the largest angle
= 19× x
= 19× 5

Define operation $\heartsuit$ so that \[ a \heartsuit b = \dfrac{a + b}{2}. \] Let $H$ be a function defined by \[H(x,y,z) = \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right). \] Write an expression for a simplified version of this function: $H(x,y,z) = \boxed{\phantom{blaaaaaaaaaa^2_2}}$ Write an expression, not an equation. Sample answer: $x + y + z$
Answers
Answer:
(-x+z)/4
Step-by-step explanation:
Evaluate the $\heartsuit$ operation to simplify.
\begin{align*}
H(x,y,z) &= \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right) \\
&= \left(\dfrac{x+y}{2}\right) \heartsuit z - x \heartsuit \left(\dfrac{y+z} 2\right) \\
&= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2}
\end{align*}This looks ugly, but it works out! Continue by multiplying each fraction's numerator and denominator by $2$, in order to eliminate the complex fractions.
\begin{align*}
H(x,y,z) &= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2} \\
&= \dfrac{x + y + 2z}{4} - \dfrac{2x + y + z}{4} \\
&= \dfrac{(x+y+2z) - (2x + y + z)}{4}
&= \dfrac{-x+z}{4}
\end{align*}Surprisingly it simplifies all the way down to $H(x,y,z) = \boxed{\dfrac{-x + z}{4}}$. The value of $y$ is not even used!
Write an equation of a line that passes through the point (0,-2) and is perpendicular to the image shown.
options:
y= 3x −2
y= −1/3x − 2
y= 1/3x
y= 3x − 10
Answers
Answer:
Brainliest Answer would be appreciated. Option 1 is the best
Step-by-step explanation:
The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.
Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.
What is the length of bd
Answers
Answer:
B
Step-by-step explanation:
I would use the Pythagorean theorem to solve distances between 2 points, and this case is no exception.
We need to find the positive difference in their x coordinates and y coordinates.
The difference in x coordinates: 7
The difference in y coordinates: 8
Now we can use the Pythagorean theorem:
7^2+8^2 = x^2
49+64 = x^2
113 = x^2
x = sqrt(113)
Therefore, the answer is B.

Answer:

the awnser is be because that sign in between x and 3 means equal to or less than. so x can be equal to or less than 3. and a closed circle means x can be equal to 3. and the line goes towards the negative because x has to be LESS THAN or equal to 3.

The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)
Answers
Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64
Solving EquationsThe equations can be solved when you replace the variable x for a given value or find the zero of functions.
The question gives:
r(x)=2x-2
s(x)=-x²
First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,
r(x)=2*(-3)-2
r(x)=-6-2= -8
Like r(-3)= -8, you should replace x, in s(x), for -8.
s(x)=-(-8)²
s(x)=-64
Hence, s(r(-3)=-64.
