Answer:
x= 29
Step-by-step explanation:
These angles equal 180° since they are corresponding angles.
So, the equation would be: (2x-10)+(4x+16)= 180.
Step 1- Add common variables.
(2x+4x)+(16-10)= 180
6x+6= 180
Step 2- Subtract 6 to both sides.
6x+6= 180
-6 -6
6x= 174
Step 3- Divide both sides by 6.
6x= 174
6 6
x= 29
Answer:
x=29
Step-by-step explanation: The two angles for are supplementary, so the equation will be equal to 180 degrees. So to find 180 degrees you need to put (2x-10) and (4x+16) on the same side of the equation.
180=(2x-10)+(4x+16) Combine like terms
180=6x+6 Subtract 6 from both sides
174=6x Divide both sides by 6
29=x
Check:
2*29-10
58-10= 48
4*29+16
116+16=132
132+48=180

"hope this helps you"
please explain the steps to me . i’m genuinely confused
Answer:See below
Step-by-step explanation:
These angles are equal. All that needs to be done is setting the equations as equal and solving for the variables. Once the variables are found, input them back into the equation to find the angles. Once the variables are put into both equations, the result should be equal.
Answer:
13) 94°
14) 105°
Step-by-step explanation:
13) For this equation, the angles are vertical angles. This means that they equal each other. So the equation would be: 14x-4= 12x+10.
Step 1- Subtract 12x to both sides.
14x-4= 12x+10
-12x -12x
Step 2- Add 4 to both sides.
2x-4= 10
+4 +4
Step 3- Divide both sides by 2.
2x= 14
2 2
x= 7
Now that you know the value of the variable, insert this into the equations.
14(7)-4= 98-4= 94°
12(7)+10= 84+10= 94°
14) For this equation, the angles are alternate exterior angles. This also means that they equal each other. So the equation would be: 16x-7= 15x.
Step 1- Add 7 to both sides.
16x-7= 15x
+7 +7
Step 2- Subtract 15x to both sides.
16x= 15x+7
-15x -15x
This leaves you with: x= 7.
Now, insert the value of the variable into the equations.
16(7)-7= 112-7= 105°
15(7)= 105°
Simplify the expression by combining like terms
7y - 6x + 3 – 2x + 8- y

Answer:
[tex]\boxed{ -8x + 6y + 11}[/tex]
Step-by-step explanation:
[tex]7y - 6x + 3 - 2x + 8- y[/tex]
[tex]= 7y + -6x + 3 + -2x + 8 + -y[/tex]
Combine Like Terms:
[tex]= 7y + -6x + 3 + -2x + 8 + -y[/tex]
[tex]= (-6x + -2x) + (7y + -y) + ( 3 + 8)[/tex]

What equation represents the line that passes through the points (0, 2) and (9, 0)?
Please help me !!
Answer:
Y = -2/9x +2
Reasoning:
This is because you simply find the slope between the 2 points
If F(x) = -3x-2 , what is F(-5)
A) F(-5)=13
B) F(-5)=-17
C) F(-5)=-13
D) F(-5)= 17
Find the slope and write an equation of the line which passes through the points.
a
(5,6) and (3,4)
b
(−3, 9) and (−3, −5)
Answer:
a. y=x+1
b. x=-3
Step-by-step explanation:
a. slope= (6-4)/(5-3)=1
substitute (5,6) to y=1x+b; b=1
therefore, y=x+1
b. x=-3

line i and line h intersect at what point
Step-by-step explanation: The intersection of two figures can
be defined as the set of points that is contained in both figures.
In this figure, lines h and i intersect at C or we can
say that C is the intersection of lines h and i.
In this figure, C is the intersection of lines h and i
because C is the point contained by both h and i.

Which statement accurately describes how to perform a 90° clockwise rotation of point A (1,4) around the origin?
A)Create a line perpendicular to the y-axis from point A, and locate a point on the perpendicular line that is equidistant to the
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90
C)Create a line perpendicular to the x-axis from point A, and locate a point on the perpendicular line that is equidistant to the
D)Create a circle with point A as its center and a radius of the origin and point A, then locate a point on the circle that is 90° CO
Answer:
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90 clockwise
Step-by-step explanation:
This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).

solve 8x-7y=18 for y?
Answer:
y = 8/7x -18/7
Step-by-step explanation:
8x-7y=18
Subtract 8x from each side
8x-8x-7y=-8x+18
-7y = -8x+18
Divide each side by -7
-7y/-7 = ( -8x+18)/-7
y = 8/7x -18/7

(6,11) and (5,9) on a line in standard form
Answer:
2x - y = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 11) and (x₂, y₂ ) = (5, 9)
m = [tex]\frac{9-11}{5-6}[/tex] = [tex]\frac{-2}{-1}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 9) , then
9 = 10 + c ⇒ c = 9 - 10 = - 1
y = 2x - 1 ← in slope- intercept form
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
From y = 2x - 1 ( subtract y and add 1 to both sides )
2x - y = 1 ← equation in standard form
