1) Given two equations: 1) y = x - 3 and 2) y = -2x + 9. graph and state the point of
intersection below: *
Your answer

Answer:

Your solution is (-10, 6).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-5x + y = 56

x + y = -4

Let's change the second equation into one with one variable on each side.

y = -x - 4

Now, plug this into your first equation.

-5x + (-x - 4) = 56

Distribute the + sign.

-5x - x - 4 = 56

Combine the like terms.

-6x - 4 = 56

-6x = 60

Isolate x by dividing both sides by -6.

x = -10

Now plug this back into either equation.

-10 + y = -4

Add 10 to both sides to find y.

y = 6

Your solution is (-10, 6).

Check this by plugging in these values into the equation you have not checked yet.

-5(-10) + (6) = 56

50 + 6 = 56

56 = 56

Your solution is correct.

Hope this helps!

Answer:

x=-10; y=6

Step-by-step explanation:

combine the equations:

-5x + y + x + y = 56 +(-4)

-4x + 2y = 52

add 4x to each side

2y=52+4x

divide by 2

y=26+2x

now substitute 26+2x for y in the second equation:

x + 26 + 2x = -4

3x + 26 = -4

3x = -30

x = -10

therefore y = 6

Answer:

X = 4

Step-by-step explanation:

414 - 108 - 130 = 176

13x + 11x + 5x + 10x + 5x = 176

44x = 176

x = 4

Answer:

x = 1 or -5/2

Step-by-step explanation:

-2x^2 - 3x + 5 = 0

multiply all through by -1

2x^2 + 3x - 5 = 0

....... 2x^2 × 5 = 10x^2 = +5x × -2x

(2x^2 + 5x)-(2x - 5) = 0

x(2x + 5) - 1(2x + 5) = 0

x - 1 = 0 or 2x + 5 = 0

x = 1 or 2x = - 5

x = 1 or -5/2

The two angles shown are vertical angles which are the same.

x+10 = 59

Subtract 10 from both sides:

x = 49

Answer:

The northern position would be positive while the southern position would be negative.

Step-by-step explanation:

Imagine 0 as the truck stop. North would be above the truck stop, while south would be below it.

On a number line, anything above 0 is a positive number. Anything below 0 is a negative number.

Therefore, the northern position would be positive while the southern position would be negative.

2. 6.57 + 1.77 + 2.98 = 11.32

Answer:

Part A.)   2.19g + 0.59b + 1.49p

Part B.)   11.32

Step-by-step explanation:

Part A.)  

basically they give you the price for each item in the upper description. Just use g,b,p in terms that they gave you

Part B.)

plug in the amount of fruit per pound for each matching variable

Answer:

7x = 35cm ; 2x = 10cm

Step-by-step explanation:

7x and 2x are the lengths

7x+2x=45

Then you take 7 + 2 = 9

so is gonna be 9x = 45

then you divide both side with 9

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

2 x 5 = 10cm

Answer:70

Step-by-step explanation:

Answer:

A 140

Step-by-step explanation:

Mark the center of the circle as O. It's given that

∠IOJ = 70°

∠JOK = 70°

from the drawing it looks like HOI, IOJ and JOK are supplementary angles, which means that they add up to 180°

∠HOI + ∠IOJ + ∠JOK = 180°

∠HOI = 180° - ∠IOJ - ∠JOK

∠HOI = 180° - 70° - 70°

∠HOI = 40°

∠HOI and ∠KOL are cross angles, therefore ∠HOI = ∠KOL = 40°

Since ∠HOL and ∠KOL are supplementary angles

∠HOL = 180° - ∠KOL

∠HOL = 180° - 40°

∠HOL = 140°

Answer:

The value of S is 11.

Step-by-step explanation:

Okay, I found this answer due to that A = S to the power of 2 right? Then, A = 121 m2, so S2 is 121 square rooted, meaning what number is multiplied the same to get 121? 11. And if you multiply 11 by 11, you get 121.
