Solve the system of equations.

babunello [35]

Answer:

option ( c ) is correct !!

Step-by-step explanation:

Given equations :-

y = -6x + 9 ________ ( i )

y = -3x + 3 .....( ii )

Equating both i and ii

-6x + 9 = -3x + 3

-6x + 3x = 3-9

-3x = -6

x = -6/-3

x = 2

Also, y = -3x + 3

y = -3(2) + 3

y = -6 + 3

y = -3

So, ( x , y ) = ( 2 , -3 )

1.
A graph of linear function is a straight line.
Linear function in a slope-intercept form: y = mx + b

Answer: Equation 3: y = 12x + 17.

2.
x|-1 | 0 | 1 | ? |
y| 4 | 7 |10| ? |

a slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

We choose:
$(-1; 4)\to x_1=-1\ and\ y_1=4\\(0;\ 7)\to x_2=0\ and\ y_2=7$

subtitute:

$m=\dfrac{7-4}{0-(-1)}=\dfrac{3}{1}=3$

a slope-intercept form: $y-y_1=m(x-x_1)$

subtitute:

$y-4=3(x-(-1))\\\\y-4=3(x+1)\\\\y-4=3x+3\ \ \ \ |add\ 4\ to\ both\ sides\\\\y=3x+7\ (*)$

subtitute x = 2 to the equation (*):

$y=3\cdot2+7=6+7=13$

Answer: (2, 13)

3.
(-2; 7), (-5; 4)

the slope: $m=\dfrac{4-7}{-5-(-2)}=\dfrac{-3}{-5+2}=\dfrac{-3}{-3}=1$

$y-7=1(x-(-2))\to y-7=x+2\ \ \ \ |add\ 7\ to\ both\ sides\\y=x+9$

check other:

$(-8;\ 1)\to L=1;\ R=-8+9=1;\ L=R-correct\\(-11;-2)\to L=-2;\ R=-11+9=-2;\ L=R-correct$

The conclusion: It's a linear function

Answer: It is a linear function because there is a constant rate of change in both the input and output values.

4.
y = 3x + 5 /look at the picture/

Answer: It is a linear function because its graph contains the points (0, 5), (1, 8), (2, 11), which are on a straight line.

check:
$(0; 5)\to L=5; R=3\cdot0+5=5;\ L=R-correct\\(1;\ 8)\to L=8;\ R=3\cdot1+5=8;\ L=R-correct\\(2;\ 11)\to L=11;\ R=3\cdot2+5=11;\ L=R-correct$

a rectangle has a length that is 4 times longer than it's width. If the total area of the rectangle is 121 square feet, what is

larisa86 [58]

Answer:

L = 22 ft

Step-by-step explanation:

Let L and W represent the length and width respectively.

L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.

Area of a rectangle: A = L · W

Here, A = L · L/4 = 121 ft²

Mult. both terms by 4 removes the fraction:

L² = 484

Finding the square root of this result: L = 22

The length of the rect. is 22 ft.

Steven goes to the grocery store and is looking at a winter squash. It has a mass of 1.8 kilograms. How many milligrams is the w

Zolol [24]

Ok so think about this ( not trying to be rude ) if a kilo = 1000 grams and a gram = 1000 milligrams then there would be 1000000 milligrams in winter squash how I got the solution is by multiplying milligram 1000 to get to a gram then multiply by 1,000 again then do 1,000 times 1,000 then you would get 1000000.
