Use two of the equations below to write a system of equations with no solution.
Y = 3x + 1
Y = 3x - 1
-Y= -3x + 1
Answer:
Y = 3x + 1
Y = 3x - 1
Step-by-step explanation:
A system of equations will have no solution if the lines are parallel to each other. Two lines are parallel when they have the same slope. All of your given equations are in the slope-intercept form. Recall the slope-intercept form is y=mx+b, where m is slope and b is the y-intercept. Therefore, the two equations would be Y = 3x + 1 and Y = 3x - 1, which both have a slope of m=3.

The sum of the ages of Gusion and Lesley is 42. Four years ago, Gusion was twice as old as Lesley. Find the present age of each.
Answer:
Gusion = 2years
Lesley= 40years
Step-by-step explanation:
Let Guison age be x
Let Lesley age be y
If the sum of the ages of Gusion and Lesley is 42, then;
x+ y =42 ... 1
Four years ago
Guison age = x - 4
Lesley age = y - 4
If four years ago, Gusion was twice as old as Lesley, then;
x - 4 = 2(y-4)
x - 4 = 2y - 9
x - 2y = -9+4
x - 2y = -5 .... 2
Substract 1 from 2;
y + 2y = 1+5
3y = 6
y = 2
From 1;
x = 42 - y
x = 42-2
x = 40
Hence present age pf Guison is 2 years
Present age of Lesley is 40 years

Emily enters a bike race for charity her mother pledges 10 cents for every 0.75 mile she bikes if Emily bikes 15 miles how much will her mom donate
Answer:
The answer is that her mom will donate $2.
Step-by-step explanation:
From the information given, you can use a rule of three to find the amount her mom will donate if Emily bikes 15 miles given that her mother pledges 10 cents for every 0.75 miles:
0.75 miles → 0.10
15 miles → x
x=(15*0.10)/0.75
x= 2
According to this, the answer is that her mom will donate $2.

Which equation represents a line which is perpendicular to the y-axis?
Answer:
The real answer is y=5
Step-by-step explanation:
because its horizontal
y=5 represents a line which is perpendicular to the y-axis
What is Straight line?A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects
We need to find the equation which represents a line that is perpendicular to the y-axis
A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.
In the given options
x=-6
y=x-4
y=5
and x=-2y
The only horizontal line is y=5
Hence, y=5 represents a line which is perpendicular to the y-axis

Area of a square is 196 cm²
. Find the perimeter of the square. (ii) If the square is altered into a rectangle by increasing the length by x
centimeters, and decreasing the breadth by y centimeters, find the area of
the rectangle in terms of x and y.
Step-by-step explanation:
Area of Square=side²
Side=√(Area of the square)
Given area of the square=196cm²
Side of the square=√196=14cm
Perimeter of square=4*side=4*14=56cm
Length of the rectangle=(14+x)cm
Breadth of the rectangle=(14-y)cm
Area of rectangle=Length*Breadth=
(14+x)(14-y)=14(14)+14(-y)+x(14)+x(-y)=(196-14y+14x-xy)cm²

Answer: X=19
Step-by-step explanation:
Add up everything and set it to 180 degrees so (5x+4)+(x-2)+(3x+7)=180
next 9x+9=180
then 9x=171
x=19
If you want to check by pluggin in value for x for all angles and it should equal 180 added up
Angle POS= 99
Angle SOR= 17
Angle ROQ= 64

CONSIDERANDO QUE A U B= { 1,2,3,4,5,6,7,8}, A U B = {4,5} e A-B = { 1,2,3}, DETERMINE O CONJUNTO B
Answer:
O conjunto B é dado por: B = {4, 5, 6, 7, 8}
Step-by-step explanation:
A U B= { 1,2,3,4,5,6,7,8}
Todos os elementos pertencem a pelo menos um desses conjuntos.
A intersecção B = {4,5}
Os elementos 4 e 5 pertencem a pelo menos um desses conjuntos. Então, tem-se os dois primeiros elementos de B, que são 4 e 5.
A-B = { 1,2,3}
1, 2, 3 são os elementos que pertencem ao conjunto A e não pertencem ao conjunto B.
Como A U B= { 1,2,3,4,5,6,7,8}, tem-se que os elementos 4, 5, 6, 7 e 8 pertencem ao conjunto B.
O conjunto B é dado por: B = {4, 5, 6, 7, 8}

What is the range of the function f(x) = 4x + 9, given the domain D={-4,-2,0, 2}?
Given:
The function is
[tex]f(x)=4x+9[/tex]
Domain = {-4, -2, 0, 2}
To find:
The range of the given function for the given domain.
Solution:
We know that domain is the set of input values and range is the set of output values.
We have, [tex]f(x)=4x+9[/tex] and domain = {-4, -2, 0, 2}.
Putting x=-4 in the given function, we get
[tex]f(-4)=4(-4)+9[/tex]
[tex]f(-4)=-16+9[/tex]
[tex]f(-4)=-7[/tex]
Putting x=-2 in the given function, we get
[tex]f(-2)=4(-2)+9[/tex]
[tex]f(-2)=-8+9[/tex]
[tex]f(-2)=1[/tex]
Putting x=0 in the given function, we get
[tex]f(0)=4(0)+9[/tex]
[tex]f(0)=0+9[/tex]
[tex]f(0)=9[/tex]
Putting x=2 in the given function, we get
[tex]f(2)=4(2)+9[/tex]
[tex]f(2)=8+9[/tex]
[tex]f(2)=17[/tex]
The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.
Therefore, the correct option is D.

Two boats sail from A. One boat sails to B, and the other boat sails to C.
BAC = 115c
The bearing of B from A is 200c.
Find the bearing of A from C.
Answer:
265°
Step-by-step explanation:
I think we have to minus 200 - 115 = 85

A plane takes off and climbs at a 10º angle. After flying over 12 miles of ground, what will the plane's altitude, h, be? Round to the nearest tenth of a mile.
=========================================================
Explanation:
A diagram is optional, but I find it helps sometimes. The diagram is shown below.
Opposite the 10 degree angle is h. So we consider h the opposite side.
The hypotenuse is 12. The hypotenuse is always opposite the 90 degree angle.
Apply the sine ratio to solve for h
sin(angle) = opposite/hypotenuse
sin(10) = h/12
12*sin(10) = h
h = 12*sin(10)
h = 2.08377813200317 which is approximate
h = 2.1 miles is the plane's altitude which is also approximate
Side note: 2.1 miles is equal to 11,088 feet (multiply by 5280 to convert from miles to feet).
