Answer:

1) (3,5)

2) infinite solutions

Step-by-step explanation:

1) sketch two lines:

Line 1: joining

(0,-4) and (1,-1)

Line 2: joining

(0,2) and (-2,0)

They will meet at (3,5)

3x - 4 = x + 2

2x = 6

x = 3

y = 5

2) sketch two lines:

Line 1: joining

(2,0) and (5,1)

Line 2: joining

(2,0) and (5,1)

These are two overlapping lines,

So infinite solutions

Answer and Step-by-step explanation:

1) If you graph the lines, you will get the lines in the first attachment. You will see that the intersection point is (3, 5), which is the solution to that system.

2) First, let's convert both of these into slope-intercept form so that they're easier to graph.

x - 3y = 2

x = 3y + 2

3y = x - 2

y = \frac{1}{3}x-\frac{2}{3}

AND

-3x + 9y = -6

9y = 3x - 6

y = \frac{3}{9} x-\frac{6}{9} =\frac{1}{3} x-\frac{2}{3}

We see that these two lines are exactly the same, which means that no matter what coordinate works for one, it will work for the other. In other words, there are infinitely many solutions.

And, if you graph these lines, you will get the graph in the second attachment, where they are the same line.

Hope this helps!

A cookie recipe calls for 1/3 of a cup of sugar and 1 1/2 cups of flour. What is the unit rate of flour to sugar for the cookie
Serggg [28]

Answer:

Rate = 4.5

Step-by-step explanation:

It is given that,

A cookie recipe calls for 1/3 of a cup of sugar and 1 1/2 cups of flour.

We need to find the unit rate of flour to sugar for the cookie recipe. It can be calculated as follows :

U=\dfrac{\text{No of cups of flour}}{\text{No of cups of sugar}}\\\\=\dfrac{1\dfrac{1}{2}}{\dfrac{1}{3}}\\\\=\dfrac{\dfrac{3}{2}}{\dfrac{1}{3}}\\\\=\dfrac{3}{2}\times 3\\\\=4.5

So, the unit rate of flour to sugar for the cookie recipe is 4.5

Determine and state an equation of the line perpendicular to the lines 5x-4y=10 and passing through the point (5,12). in point-s
sergey [27]
Perpendicular lines have slopes that are negative reciprocals of one another.

slope intercept form (y = mx + b) of the first equation will help us find the slope of the first line: where m = slope

5x-4y=10
-4y=-5x + 10
y=-5/-4 x + 10/-4
y=5/4 x -2.5

if the slope of this line is 5/4 then the slope of the perpendicular line is -4/5.

Therefore with the given information we can state the equation of the second line in point slope form (y-y,) = m(x-x,)

the coordinates of (5,12) can are substituted for x, and y,

so the answer is

(y-12) = -4/5(x-5)

I hope this helped and is BRAINLIEST!

Good luck with your studies!

SOMEONE HELP! PLEASE! read the attached files
Trava [24]

Answer: 43 squared units

Explanation:

So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area

So basically since this one is a open polygon you can just count the inside of the poly using the squares
