Solve for x plsss helpppp
Answer:
x=30
Step-by-step explanation: First we would have to find the two angles of the corner of the triangle. 55° in the bottom left because of verticle angles. And 180-120= 60. And 60+55=115. 180-115=65. 65-5= 60. 60/2= 30. So x=30. (Sorry ik its sloppy) :)

Which value of X will allow the following set of ordered pairs to represent a function? (3,7) (2,6) (x,8) (1,5)
Answer:
[tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.
Step-by-step explanation:
From Function Theory, we know that a function is a relation in which all domain elements are not related to at least two different elements from range. Which means that [tex]x \in \mathbb{R}-\{1,2,3\}[/tex], that is, that [tex]x[/tex] is a real number different to 1, 2 and 3.
Hence, we conclude that [tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.
I need help on this. Only right answers only please..
what is P versus NP, its supposed to be one of the hardest questions in the world
Answer:
P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.
Step-by-step explanation:

Consider the following graph which represents the solutions to a system of inequalities. Which of the following systems of inequalities does the graph represent?
Answer:
The system of inequalities is -2x + y > 0 -x + y ≥ 0
Step-by-step explanation:
The form of the equation of a line is y = m x + b, where
m is the slopeb is the y-interceptThe line passes through the origin, then
The value of b = 0The form of the equation is y = m xLet us look at the graph to find the correct answer
∵ One of the lines are solid and the other is dashed
∵ The shaded area is over the two lines
∴ The signs of the two inequalities are ≥ and >
∵ The two lines pass through the origin
→ That means the y-intercepts are 0
∴ The form of the inequalities are y ≥ m[tex]_{1}[/tex] x and y > m[tex]_{2}[/tex]
There are only two answers that have these forms, so we must find the slope of each line
∵ m = [tex]\frac{y2-y1}{x2-x1}[/tex] , (x1, y1) and (x2, y2) are two points on the line
∵ The solid line passes through points (0, 0) and (2, 2)
∴ m[tex]_{1}[/tex] = [tex]\frac{2-0}{2-0}[/tex] = [tex]\frac{2}{2}[/tex] = 1
→ Substitute it in the form of the equation
∴ y ≥ 1(x)
∴ y ≥ x
→ Subtract x from both sides
∴ -x + y ≥ 0
∵ The dashed line passes through points (0, 0) and (1, 2)
∴ m[tex]_{2}[/tex] = [tex]\frac{2-0}{1-0}[/tex] = [tex]\frac{2}{1}[/tex] = 2
→ Substitute it in the form of the equation
∴ y > 2(x)
∴ y > 2x
→ Subtract 2x from both sides
∴ -2x + y > 0
The system of inequalities is -2x + y > 0 -x + y ≥ 0
Answer:
The system of inequalities is -2x + y > 0 -x + y ≥ 0

Step-by-step explanation:
Juan is three times as old as Gabe and Gabe is six years older than Catherine. If the sum of their ages is 149, how old is each person? Define a variable, write an equation, solve the equation, and answer in a complete sentence.
Answer:
Juan = 93 years.
Gabe = 31 years.
Catherine = 25 years.
Step-by-step explanation:
Let the age of Juan = J
Let the age of Gabe = G
Let the age of Catherine = C
Translating the word problem into an algebraic equation, we have;
[tex] J = 3G[/tex] ..........equation 1
[tex] G = C + 6 [/tex] ........equation 2
[tex] J + G + C = 149 [/tex] ........equation 3
We would solve the linear equations by using the substitution method;
Substituting equation 2 into equation 1;
[tex] J = 3(C + 6)[/tex]
[tex] J = 3C + 18[/tex] ........equation 4
Substituting equation 2 and equation 4 into equation 3;
[tex] (3C + 18) + (C + 6) + C = 149 [/tex]
Simplifying the equation, we have;
[tex] 5C + 24 = 149[/tex]
[tex] 5C = 149 - 24[/tex]
[tex] 5C = 125[/tex]
[tex] C = \frac {125}{5}[/tex]
C = 25 years.
To find G; from equation 2
[tex] G = C + 6[/tex]
Substituting the value of "C" into equation 2, we have;
[tex] G = 25 + 6[/tex]
G = 31 years.
To find J; from equation 1
[tex] J = 3G [/tex]
Substituting the value of "G" into equation 1, we have;
[tex] J = 3 * 31[/tex]
J = 93 years.
Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old.

write an equation of the line with the given information. m. 4. A(-1.-5)
Answer:
An equation of the line with the given information with
m = 4 and point A(-1, -5) is:
[tex]y=4x-1[/tex]Step-by-step explanation:
As the equation of a line in point-slope form is given by:
[tex]y-y_1=m\left(y-x_1\right)[/tex]
where m is the slope.
Given:
the slope m = 4 the point A(-1, -5)Substituting the values in the equation of a line in point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)[/tex]
[tex]y+5=4\left(x+1\right)[/tex]
subtract 5 from both the sides
[tex]y+5-5=4\left(x+1\right)-5[/tex]
[tex]y=4x-1[/tex]
Therefore, an equation of the line with the given information
with m = 4 and point A(-1, -5) is:
[tex]y=4x-1[/tex]what is the directrix of a parabola with focus (4,-1) and a vertex at (4,-5)?
Answer:
y = -9Step-by-step explanation:
The directrix is at the same distance from the vertex as the focus but on the opposite side of the vertex.
x coordinate the same for a focus and a vertex (4) means the parabola opens up or down and the directrix is parallel to the x-axis.
y coordinate of the focus greater than y coordinate of the vertex means the parabola opens up and the directrix lays below the vertex.
-1-(-5) = - 1 + 5 = 4
so: - 5 - 4 = -9 is the y coordinate of points of the directrix
Solve the simultaneous equations
2x + 3y = 6
7x – 2y = 1
Answer:
x=0.6, y=1.6
Step-by-step explanation:
Multiply the first equation by 2 and the second equation by 3, so we can cancel out the y terms:
4x+6y=12
21x-6y=3
Add these 2 equations together:
25x=15
x=0.6
Now, to solve for y, plug x back into any of the equations above:
2(0.6)+3y=6
1.2+3y=6
3y=4.8
y=1.6
Answer:
Below in bold.
Step-by-step explanation:
2x + 3y = 6 Multiply by 2:
7x – 2y = 1 Multiply by 3:
4x + 6y = 12
21x - 6y = 3 Adding:
25x = 15
x = 0.6. Substitute x = 0.6 into the first equation:
2*0.6 + 3y = 6
3y = 6 - 1.2 = 4.8
y = 1.6.

the time, t, in seconds, is required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given this equation
Answer:
C. [tex] d = \frac{at^2}{2} [/tex]
Step-by-step explanation:
Given:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Required:
Make d the subject of the formula.
SOLUTION:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Square both sides
[tex] t^2 = (\sqrt{\frac{2d}{a}})^2 [/tex]
[tex] t^2 = \frac{2d}{a} [/tex]
Multiply both sides by a
[tex] a*t^2 = \frac{2d}{a}*a [/tex]
[tex] at^2 = 2d [/tex]
Divide both sides by 2
[tex] \frac{at^2}{2} = \frac{2d}{2} [/tex]
[tex] \frac{at^2}{2} = d [/tex]
[tex] d = \frac{at^2}{2} [/tex]

what this dont get it
Answer:
[tex]4p+3[/tex]
Step-by-step explanation:
All this question is asking you to do is simplify the given expression by combining like terms.
The point of combining like terms is that you can only combine, well, like terms. Like terms are terms that have the same variables and are raised to the same power. This means that in this case, we can't combine [tex]4[/tex] and [tex]6[/tex] because [tex]4[/tex] is attached to a variable. However, we can combine 6 and -3 because they are like terms; neither is attached to a variable. So, you end up with [tex]4p+3[/tex].
I hope this helps!
