Answer: x=68, y=37
Step-by-step explanation:
The equation for the sum of two numbers is 105 would be x+y=105. You can say the larger number would be x and the smaller would be y. So, x=2y-6. then you plug that into the x in the first equation.
2y-6+y=105
3y-6=105
3y=111
y=37
Then you would plug in the y to one of the equations. I will do the second one but you can do either one.
x=2y-6
x=2*37-6
x=74-6
x=68
2x - 2y = 6 3x + 2y = 9 Solve the system of equations. A) x = 0, y = 3 B) x = 3, y = 0 C) x = 1, y = -2 D) x = -2, y = 1 E) x = 6, y = 3
There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.
[tex]2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\[/tex]
Now we will solve for y using what we got for x.
[tex]2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0[/tex]
Solution:
A: [tex](0, 3)[/tex]
Consider the table for f(x) and the graph for g(x). Which statement is true when comparing the y-intercepts of the functions?
A) The y-intercept for f(x) is greater than the y-intercept for g(x).
B) The y-intercept for both functions is (0,0).
C) The y-intercept for g(x) is greater than the y-intercept for f(x)
D) The y-intercept for both functions is (0, 2).
Answer:
Should be C
Step-by-step explanation:
The y-intercept for f(x) is greater than the y-intercept for g(x). Therefore, option A is the correct answer.
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
From the table, we have the coordinates (-2, 0) and (-1, 1).
Here, slope (m)=(1-0)/(-1+2)
m=1
Substitute m=1 and (x, y)=(-2, 0) in y=mx+c, we get
0=1(-2)+c
c=2
From the graph y-intercept is c=1
Therefore, option A is the correct answer.

Which number line shows all the values of x that make the inequality
-3x + 1 < 7 true?
Answer:
C
Step-by-step explanation:
A closed circle means inclusive, and -2 is included in values that would make the equation true. Then you just have to test another number greater than and less than -2 to see which way the arrow should point.
-3(-3) + 1 < 7
9 + 1 < 7
10 < 7 FALSE
-3(0) + 1 < 7
1 < 7 TRUE
All values (including -2) will make this equation true

-3x-4y=11
y=2x
Answer:
x = -1, y = -2
Step-by-step explanation:
-3x-4y=11
y=2x
Plug in 2x for y:
-3x-4(2x)=11
-3x-8x = 11
-11x = 11
x =-1
Plug in x in y = 2x
y = 2(-1)
y = -2

Eliza claims that the two squares are congruent. Which statement could be used to prove Eliza's claim?
A) Any two squares are congruent since all squares have angles of 90 degrees
B) The two squares are congruent since a translation carries one square onto the other.
C) Any two squares are congruent since all four sides of any square are congruent.
D) The two squares are congruent since a rotation about the origin carries one square onto the other.
Answer:
A
Step-by-step explanation:
I Hope this helps you out!
Eliza claims that the two squares are congruent. The statement that could be used to prove Eliza's claim can be found in Option A.
Any two squares are congruent since all squares have angles of 90 degrees.
A figure is said to be congruent if they have similar angles and the position of each shape corresponds to each other.
From the given figure attached to the question, we can see that the two shapes in the figure are squares, and they are located at 2 units each from the origin. The angles of each shape are 90° to the horizontal line and they are perpendicular to each other.
The two squares may not be congruent since not only translation carries one square onto the other, from the figure in the question, it may be a reflection and not only translation.
Also, only the sides of a shape cannot be used as a determining factor to determine if a shape is congruent or not.
Therefore, we can conclude that any two squares are congruent since all squares have angles of 90 degrees.

You may find it easier to solve these by hand if you eliminate fractions.
2x -y +z = -2x +3y -z = 10x +0y +2z = -8The first step is to look to see what you have, then formulate a strategy for getting a solution. Because the equations containing y have opposite coefficients, one of which is -1, we choose to use those to eliminate y. Immediately, we will have two equations in x and z.
If you multiply the first equation by 3 and add that to the second, then you will eliminate y. The third equation already has y eliminated, so you will then have two equations in x and z.
3(2x -y +z) +(x +3y -z) = 3(-2) +(10)
6x -3y +3z +x +3y -z = -6 +10
7x +2z = 4 . . . . [eq4]
Subtracting the third equation from this eliminates z, so you have ...
(7x +2z) -(x +2z) = (4) -(-8)
6x = 12
x = 2
Substituting into the third equation gives ...
2 +2z = -8
2z = -10
z = -5
Then using the first equation, you have ...
y = 2x +z +2 = 2(2) +(-5) +2 = 1
(x, y, z) = (2, 1, -5)
2x – 3y = 17 –3x + y = –1

Perpendicular means opposite reciprocal of the slope. This means that the slope would change from 2/5 to 5/2 and add a negative, so it is -5/2.
