Answer:
y=x-6
Step-by-step explanation:
Y=x+3 according to this equation, the gradient is 1 comparing to y=mx+c. so m is the gradient. so from the equation, the coefficient of x is 1. since the line is parallel so it means the new equation has the same gradient m.
y=x+c but it passes through 1,-5...when x= 1, y=-5 from here , we Can find the new intercept c. -5=1+c. so c=-5-1=-6
the new equation y=x-6

The equation is y=-3/4x+6. (Note the 3/4 is negative because the line has a negative slope.
Let me know if this helps :)
Answer:
[tex]\huge \boxed{y=-\frac{3}{4}x+6 }[/tex]
Step-by-step explanation:
Two points are (0, 6) and (8, 0)
Finding the slope.
m = (y2-y1)/(x2-x1)
m = (0-6)/(8-0)
m = -6/8
m = -3/4
The y-intercept is 6.
y = mx + b
m = slope
b = y-intercept
y = -3/4x + 6
Given x=-3, y=6, and z=-4 2z-3y+4x=
Solution:
Given, x=-3, y=6 and z=-4
Putting the value in the given equation: 2z-3y+4x, we will get,
=2(-4)-3(6)+4(-3)
=-8-18-12

A map of the town that Annie, Barbara, and Charlie live in can be represented by the Cartesian plane. Annie is located at $(6,-20)$ and Barbara is located at $(1, 14)$. They agree to meet at the closest point that is equidistant from their current locations and walk upwards together to get to Charlie's location at $\left(\frac{7}{2}, 2\right)$. How many units upward do Annie and Barbara walk together to get to Charlie?
Answer:
5 units
Step-by-step explanation:
Annie is located at (6,-20) and Barbara is located at (1, 14) and they meet at a point equidistant to their current locations.
This means that they have to meet at the midpoint between their two locations. Let the coordinate of the midpoint be (x,y) hence:
[tex]x=\frac{x_1+x_2}{2}=\frac{6+1}{2} =\frac{7}{2}[/tex]
[tex]y=\frac{y_1+y_2}{2}=\frac{-20+14}{2} =-3[/tex]
The point at which they met is at (7/2, -3). Charlie location is at (7/2, 2). Hence the distance upward that they have to move = 2 - (-3) = 5 units
They have to move 5 units upwards

Step 1: Replace variables
[tex]\frac{(k+3)-2}{3+1} =\frac{3}{4}[/tex]
Step 2: Combine like terms
[tex]\frac{k+1}{4} =\frac{3}{4}[/tex]
Step 3: Solve for k
k + 1 = 3
k = 2
Answer:
k=2
Step-by-step explanation:
The slope is 3/4
The slope formula is (y1-y2)/(x1-x2)
We can plug the values in
(2-k-3)/(-1-3)=3/4
Combine like terms
(-1-k)/-4=3/4
Cross multiply
-12= -4 - 4k
-8=-4k
k=2

What is the solution to this linear system? Enter a value in each box to create an ordered pair.
Answer:
(2, 3)
Step-by-step explanation:
First of all, let us understand what does a linear system mean.
A linear system means a mathematical model that contains more than one linear equations.
Linear equations mean maximum power of the variable is 1.
Now, how to solve for system of linear equations.
There are two methods to solve the system:
1. From equations: A linear equation is generally written as:
[tex]Ax+By+C=0[/tex]
Two such equations are solved for the values of [tex]x[/tex] and [tex]y[/tex].
2. From Graph:
The intersecting point of the graphs of the equations is the solution of the system of linear equations.
Now, let us consider the given graph of two lines.
The intersecting point is (2, 3)
Where 2 is the value of x coordinate and
3 is the value of y coordinate.
So, solution is (2, 3)
Please refer to the attached image for the answer.
We want to see the solution of a system of equations by looking at its graph, we can see that the solution is the point (2, 3)
A system of equations is a group of equations that must be solved simultaneously. When graphed, these solutions appear as intersections between the curves that represent each equation.
So for the graphed system, the solution is just the intersection between the two lines, we can see that it happens at the point (2, 3).

simplify: 3x(x^2 + 4x - 5)
Answer:
3x^3+ 12x^2-15x
Step-by-step explanation:
First, you would have to distribute the 3x to everything in the parentheses. So you can write it out as (3x*x^2)+(3x*4x)+(3x*5). Solving this will give you the answer. We'll start off with (3x*x^2). Because we are MULTIPLYING, this part will equal to 3x^3. There is ONE x with 3x (think of it as 3x^1) and 2 x's in x^2, having a total of 3 x's, or x^3. Since the 3 is being multiplied as well, we can write it as 3x^3.
Second, we will solve (3x*4x). We are multiplying, so first we multiply 3*4 and then x*x. 3*4 is 12 and x*x is x^2. There are 2 x's being mutipled by each other, so the x becomes squared. Now we finish and multiply 12*x^2 wich is 12x^2.
Lastly, we solve (3x*5). 3x is being multiplied 5 times which gives us 15x.

Evaluate this expression: 3x + 9x -5
Answer:
12x - 5
Step-by-step explanation:
3x + 9x - 5 can be easily simplified by combining like terms.
3x and 9x are like terms because they both contain the same variable and the same exponent (understood to be 1).
Therefore, because an addition sign separates the two terms, it is expected of you to add the two together. To do this, just add the terms together as you would any other terms.
3x + 9x = 12x
Because the 5 is the only constant in the equation, it cannot be combined with anything else.
The simplified expression is 12x - 5.

The graph of this table would not be linear.
Answer:
A B and E
Step-by-step explanation:
The statement that is true about the equation xy = 3 is:
When x = 3, y = 1.
Option B is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
xy = 3
When x = 3, y = 1
Substitute x = 3.
3 x y = 3
y = 1
This is true.
Now,
x varies directly with y.
This means,
x ∝ y
But xy = 3
x = 3/y
This is not possible.
Now,
The graph of this table would not be linear.
xy = 3
x = 1, y = 3
x = 2, y = 3/2 = 1.5
x = 3. y = 1
x = 4, y = 3/4 = 0.75
The rate of change is not the same.
So,
xy = 3 is not linear.
Thus,
When x = 3, y = 1 statement is true.

Given the points C(-1,-5) and D(-7,11) find the coordinates of point E on CD such that the ratio of CE to ED is 5:3.
((Yes im this stupid, please help-))
Answer:
The coordinates of point E on CD are [tex]\left(-\frac{19}{4},5 \right)[/tex].
Step-by-step explanation:
Let be [tex]C = (-1,-5)[/tex], [tex]D = (-7,11)[/tex] and [tex]\frac{CE}{ED} = \frac{5}{3}[/tex]. The given ratio can be translated vectorially into this:
[tex]\overrightarrow {CE} = \frac{5}{3} \cdot \overrightarrow{ED}[/tex]
And let consider that each point is a vector with respect to origin:
[tex]\vec C = (-1, -5)[/tex] and [tex]\vec {D} = (-7,11)[/tex]
Then,
[tex]\vec E -\vec C = \frac{5}{3}\cdot (\vec D -\vec E)[/tex]
[tex]\vec E +\frac{5}{3}\cdot \vec E = \frac{5}{3}\cdot \vec D + \vec C[/tex]
[tex]\frac{8}{3}\cdot \vec E = \frac{5}{3}\cdot \vec D + \vec C[/tex]
[tex]\vec E = \frac{5}{8}\cdot \vec D + \frac{3}{8}\cdot \vec C[/tex]
[tex]\vec E = \frac{5}{8}\cdot (-7,11)+\frac{3}{8}\cdot (-1,-5)[/tex]
[tex]\vec E = \left(-\frac{35}{8},\frac{55}{8} \right)+\left(-\frac{3}{8},-\frac{15}{8} \right)[/tex]
[tex]\vec E = \left(-\frac{35}{8}-\frac{3}{8},\frac{55}{8}-\frac{15}{8} \right)[/tex]
[tex]\vec{E} = \left(-\frac{19}{4}, 5\right)[/tex]

A custom T-shirt shop spent $250 dollars on equipment and has to purchase the T-shirts at a cost of $2 per shirt. Their total cost, C, can be found using the function C=2T+250 Where T is the number of T-shirts they purchase. If the shop purchased 300 T-shirts, how much was their total cost?
Answer:
The total cost is $850
Step-by-step explanation:
From the function
C = 2T + 250
where
T is the number of T-shirts they purchase.
If the the shop purchases 300 T-shirts, then it means
T = 300
substituting into the function, we have
C = 2(300) + 250
C = 600 + 250
c = $850

Marcus is putting new tiles on his kitchen fllor. The kitchen floor is 6.1 feet wide and 9.5 feet long. How many square feet of tile will Marcus need to purchase?
Answer:
57.95
Step-by-step explanation:
The area of the floor is (6.1 ft)(9.5 ft) = 57.95 ft². This will be the minimum that Marcus will want to purchase.
If we assume that tiles come in pieces 1 ft square, then Marcus will need a minimum of 58 square feet.
If Marcus does not want to piece together any tiles at the edges, he will want to purchase 10×7 = 70 square feet of tile.
