We can see that the lines intersect at: (-5,-3)

Step-by-step explanation:

Given system of equations is:

$y = \frac{2}{5}x-1\ \ \ \ Eqn1\\2x-3y+1 = 0\ \ \ \ Eqn2$

Lets convert the second equation in the same form as the first equation

$2x-3y+1 = 0$

Adding 3y on both sides

$2x-3y+1+3y = 0+3y\\2x+1 = 3y\\3y= 2x+1$

Dividing both sides by 3

$\frac{3y}{3} = \frac{2x+1}{3}\\y = \frac{2}{3}x+\frac{1}{3}\\$

The graph of equation can be plotted using manual graphing or any online graphing calculator

We will use the Desmos online graphing calculator to graph the equations (Picture attached)

We can see that the lines intersect at: (-5,-3)

Help ME! solve for ∠K.

Ainat [17]

Answer:

Step-by-step explanation:

Every Triangle has 180 degrees.

x + 8x + 3x = 180

12x = 180

x = 180/12

x = 15

Angle K = 3x

K = 3 * 15

K = 45

A storekeeper has two kinds of flour, one selling for 65 cents per pound, and the other selling for 95 cents per pound. How many

Murrr4er [49]

Answer:

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

Step-by-step explanation:

Let

x ----> amount of 65 cents per pound flour to use

y----> amount of 95 cents per pound flour to use

we know that

$x+y=100$ ----> $y=100-x$ ----> equation A

$0.65x+0.95y=0.83(100)$ ----> equation B

substitute equation A in equation B

$0.65x+0.95(100-x)=0.83(100)$

Solve for x

$0.65x+95-0.95x=83$

$0.95-0.65x=95-83$

$0.30x=12$

$x=40\ lb$

Find the value of y

$y=100-40=60\ lb$

therefore

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

If f(x) = 3x^2-10x+2 find the vertex of y=f(x+4)-5

allochka39001 [22]

$3 {(4 + x)}^{2} - 10(x + 4) + 2 - 5$
so
$3( {x}^{2} + 8x + 16) - 10x - 40 + 3$
so
$3 {x}^{2} + 14x + 11$
take differential calculus
$6x + 14 = 0$
you will find x then y

Question is in picture :) also pls explain (if u can)

The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.

With m + m + m you are adding it 3 times.

So instead multiply m by 3:

The answer is 3m
