Answer:
y=5x+46
Step-by-step explanation:
apply point
-1=5(9)+n
-1=45+n
n=-46
y=5x+46
Answer:
y + 1 = 5(x - 9)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = 5 and (a, b ) = (9, - 1 ) , then
y - (- 1) = 5(x - 9) , that is
y + 1 = 5(x - 9)
For which of the following inequalities, is -4 part of the solution set? Select all that apply. A. x > -5 . B. 2 > X . C. 3x + 4 > -8 D. 5x < 2x - 3 E. ---6 < 4 - 2x
[tex]-4[/tex] is a part of the solution set to all of the inequalities
We will consider each inequality in turn:
For [tex]x>-5[/tex]:
The solution set is [tex]\{{-4,-3,-2,-1,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]x>-5[/tex]
For [tex]2>x[/tex], or [tex]x<2[/tex]:
The solution set is [tex]\{{1,0-1,-2,-3,-4,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]2>x[/tex]
For [tex]3x+4\ge -8[/tex]:
We have to solve first
[tex]3x+4\ge -8\\3x\ge -8-4\\3x\ge -12\\x\ge -4\\[/tex]
The solution set is [tex]\{{-4,-3,-2,-1,0,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]3x+4\ge -8[/tex]
For [tex]5x\le 2x-3[/tex]:
We have to solve first
[tex]5x\le 2x-3\\5x-2x\le-3\\3x\le-3\\x\le-1[/tex]
The solution set is [tex]\{{-1,-2,-3,-4,-5,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]5x\le 2x-3[/tex]
For [tex]-6<4-2x[/tex]:
We have to solve first
[tex]-6<4-2x\\2x<4+6\\2x<10\\x<5[/tex]
The solution set is [tex]\{{4,3,2,...,-3,-4,-5,...\}[/tex]
So [tex]-4[/tex] is a part of the solution set of [tex]-6<4-2x[/tex]
So, [tex]-4[/tex] is a part of the solution set of all the inequalities.

What coordinates do I plot at
Answer:
Step-by-step explanation:
y - 10 = -2(x - 10)
y - 10 = -2x + 20
y = -2x + 20 + 10
y = -2x + 30
When x = 0 ; y = 0 + 30 = 30 ; (0,30)
When x = 10 ; y = -2*10 + 30 = -20 +30 = 10 ; (10 , 10)
When x = 5 ; y = -2*5 + 30 = -10 + 30 = 20 ; (5 , 20)

solve the system of equations by elimination:
3x+y=5
2x-2y=-2
Answer:
(x, y) = (1, 2)
Step-by-step explanation:
The method of elimination works best when the coefficient of a variable in one equation is equal or opposite the coefficient of the same variable in the other equation.
Here, we notice that all of the coefficients of the second equation are multiples of 2. When we divide that equation by 2, we get ...
x -y = -1
This equation has a y-coefficient that is the opposite of the y-coefficient in the first equation. We can eliminate the y-variable by adding these equations together.
(3x +y) +(x -y) = (5) +(-1)
4x = 4 . . . . . . . simplify. Notice the y-variable has been eliminated.
x = 1 . . . . . . . . divide by 4
Using this value of x in the second equation, it tells us ...
1 -y = -1
Adding y+1 to both sides of this equation gives ...
2 = y
The solution to the system of equations is (x, y) = (1, 2).

Answer:
At the bottom of the text.
Step-by-step explanation:
The triangle is isosceles. The measure of the two internal angles J and K are equal; The misure of the external K angle (2) is half a circle minus the internal K (1). The internal angle in R is calculated by difference between 180 and twice the internal K angle (1).
1. 72° as well.
2. 180-70-70 = 40°
3. [tex]m\angle2 = 110 \rightarrow m\angle1 =70[/tex], Same as #2: 40°
4. [tex]x+2x+2x = 180 \rightarrow 5x=180 \righarrow x= 36[/tex]
5. [tex]x +(x+30)+(x+30) = 180 \rightarrow 3x +60 = 180 \rightarrow 3x= 120 \rightarrow x=40[/tex]

Answer:
y=55
z=38
x=84
Step-by-step explanation:
Important thing to understand is that the angles in a triangle all add up to 180
A straight line also has an angle measure of 180
In the triangle on the left hand side. You can find y pretty easily
35+90 ( the angle is marked as a right angle) = 125
180-125 = 55
so y = 55
z can be found the same way
52+90 ( again marked) = 142
180-142 = 38
so z = 38
Since a straight line has a angle measure of 180 we can find x
z+y+x = 180
38+55+x=180
96+x=180
x=84
z:-
180-52-90180-14238°x
x+z=35+90x+38=125x=87°y:-

Answer:
a1=130;an=an−1+10
Step-by-step explanation:
The answer is the third one.
She starts with 130
a1 = 130
She adds 10 every month.
So you take the number she had last month (represented by a_n-1) and adds 10.
Answer
a1 = 130
an = an_1 + 10
