1) 2x-4y=6
3x+6y=9
2) 3x+y=12
-3x+6y=6
3) -2x+4y=4
-3x+6y=6
4) 3x+6y=9
-2x-4y=4
Answer:
system 4.
Step-by-step explanation:
3x+6y=9
multiply by 2
6x+12y=18 ....(1)
-2x+-4y=4
multiply by 3
-6x-12y=12 ...(2)
add (1) and (2)

Answer:
The four sides of the lines tangent to the circle are equal.
Step-by-step explanation:
Inscribed circle is inside the four or more lines of a geometric shape. In the given inscribed circle the there are four lines which are tangent to the circle. The four line are equal in length and two of the lines are parallel. This confirms that the geometric shape is a square.

One addend is 4/10
What is the missing addend?
Answer:
The missing addend is 1/20
Step-by-step explanation:
Variable x: missing addend
4/10 + x = 45/100
When adding or subtracting fractions, the denominators must be the same number.
To convert 10 to 100, we must multiply 10 by 10.
If we multiply 10 to the denominator, we must do the same to the numerator (multiply by 10).
4 × 10 / 10 × 10
40/100
Use this fraction in the equation now
40/100 + x = 45/100
Now isolate the variable, x, by subtracting 40/100 from both sides
40/100 - 40/100 + x = 45/100 - 40/100
When subtracting fractions, only subtract the numerators. The denominators remain the same
x = 5/100
Simplify 5/100
Both numbers can be divided by 5
5 ÷ 5 / 100 ÷ 5
1/20

Step-by-step explanation:
tanA=opp/adj
tan48=EH/EF
1.11061251483=32/EF
EF=28.8129294175
tanA=opp/adj
tan35=EH/EG
0.70020753821=32/EG
EG=45.7007362157
EG=FG+EF
45.7007362157=FG+28.8129294175
FG=16.8878067982
a²=b²+c²
FH=√(EF²+EH²)
FH=√(28.8129294175²+32²)
FH=43.0602473474
a²=b²+c²
GH=√(EG²+EH²)
GH=√(45.7007362157²+32²)

Geometry Will give Brainlist
Given :
segment AE and segment BD bisect each otherWhich means :
∠BCA and ∠DCE are equal because they are vertically opposite angles. Segment AC = segment CE because the bisector BD divides the segment AE into two equal parts which are segment AC and segment CE.segment BC and segment CD will be equal because bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.Since two sides and one included angle is equal △ACB≅△ECD under the SAS congruence criterion .

What is the intercept of
y=-1/2x-1 and y=1/4x-4
Answer: The y-intercept of y = -1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
The attachment shows the graph of these equations.
Step-by-step explanation:
Both equations are in slope-intercept form. y = mx + b
The constant, b, is the y-intercept.
The y-intercept of y = 1/2x -1 is (0,-1)
The y-intercept of y = 1/4x -4 is (0,-4)
What is y- intercept?On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
Given:
y=-1/2x-1 and y=1/4x-4
For Finding the y- intercept put x= 0 we get
y = -1/2(0) -1
y= 0- 1
y= -1.
For Finding the y- intercept put x= 0 we get
y=1/4(0)-4
y= 0- 4
y= -4
