Write the slope intercept form of a line through (6, -7) and parallel to y= x - 9

Mathematics
1 answer:
AveGali [126]4 years ago

Answer:

y = x - 13

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 )

y = x - 9 ← is in slope- intercept form

with slope m = 1

Parallel lines have equal slopes, thus

y = x + c ← is the partial equation of the parallel line

To find c substitute (6, - 7) into the partial equation

- 7 = 6 + c ⇒ c = - 7 - 6 = - 13

y = x - 13 ← equation of parallel line

What is the solution to the system of equations graphed below? y = x - 2 y = 4x - 5
ololo11 [35]
There are 3 available methods - Substitution , Elimination and <span>Matrix.  

</span>The substitution<span> method is used to eliminate one of the variables by replacement. 
</span>
The elimination method<span> is used for solving linear systems. 
</span>
<span>A Matrix is an array of numbers. 
</span>
Lets use Substitution to solve this system. 

x-2=4x-5 

-2=4x-5-x 

-2=(4x-x)-5&#10;&#10; &#10; 

-2=3x-5 

-2+5=3x 

3=3x 

3=3x / 3 

x=1 

Now substitute <span>x=1  
</span>
y=x-2 

y=1-2&#10;&#10; &#10; 

y=-1&#10;&#10; 

Hence - x=1&#10; &#10;y=-1

Someone PLZ ANSWER QUICK PLZ !! :)
Verizon [17]

Answer: Option c.

Step-by-step explanation:

To find surface area, add two area of circle and curved surface area.

Curved surface area formula = 2*π*r*h, where r = radius, h = height.

So total surface area will be,

2π*r ^ 2 + 2*π*r*h

Remember that radius(r) = 4 because diameter is given in figure.

The Science Club wants to print stickers to promote their club and an interest in science. They got a quote to print the sticker
zloy xaker [14]

Answer:

The system of equations =

25 + 0.05x = 12 + 0.09x

The number of stickers where the cost of both printers to be equal is 325 stickers

Step-by-step explanation:

Let the number of stickers = x

Printer 1

Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.

$25 + $0.05× x

25 + 0.05x

Printer 2

Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.

$12 + $0.09 × x

12 + 0.09x

We equate both equations together

The system of equations =

25 + 0.05x = 12 + 0.09x

Collect like terms

25 - 12 = 0.09x - 0.05x

13 = 0.04x

x = 13/0.04

x = 325 stickers

Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers
