Answers

Answer: -2.5,   -5.5

Step-by-step explanation:

5x - y= -7

3x - y= -2 multiply by -1

5x - y= -7

-3x + y= +2 we add both equations

2x=-7+2,  2x=-5,   x=5/2= -2.5

5(-2.5)-y=-7

- 12.5-y= -7 we simplify and get

-y=-7+12.5,             -y=5.5,    y=-5.5

U is between G and B. R is between G and U. if GR is 3x-2, RU is 5x+7 , UB is 12 and GB is 15x-11.

x is ____

GR is ____

GB is ____

please help! ​

Answers

Answer:

x is 4

GR is 10

GB is 49

Step-by-step explanation:

If U is between G and B, then GU + UB = GB .... 1

If R is between G and U, GR + RU = GU ....2

Given

GR is 3x-2

RU is 5x+7

UB is 12

GB is 15x-11

Substitute2 into 1;

Frim 1;

GU + UB = GB

(GR+RU) + UB = GB

3x-2+5x+7+12 = 15x-11

8x+17 = 15x-11

8x-15x = -11-17

-7x = -28

x = 28/7

x = 4

Get GR:

GR = 3x-2

GR = 3(4)-2

GR = 12-2

GR = 10

Get GB:

GB = 15x-11

GB = 15(4)-11

GB = 60-11

GB = 49

T=PV/K

Starting with V=KT/P, multiply P on both sides to get PV=KT

Then divide K on both sides to leave T alone

And you get.....T =PV/K

Answer:

The light blue/greenish one that says T=PV/K or Greeland

Step-by-step explanation:

We can make the equation more simplier by multiplying both sides by P to remove fractions.

It would become VP=KT

The only answer with VP or PV is B, or the T=PV/K

also, to isolate T, divide the VP=KT by K on both sides to isolate T.

VP/K=T

Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)

Answers

answer would be “y=4”

to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)

plug it in to get: (4-4 / 1- -3) = 0/4 = 0

this means the slope would be 0

if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:

you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:
y-4 = 0 (x - -3) or y-4 = 0(x-1)

it doesn’t matter which coordinates you use..

then solve the point slope for slope-intercept.

y-4 = 0(x-3) multiply 0 with x and -3
y-4 = 0x move -4 to the right by adding 4

y = 0x + 4 or y = 4 would be your answer!

The equation for the line that passes through the point A ( -3 , 4 ) and

B ( 1 , 4 ) is y = 4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first point be A ( x₁ , y₁ ) = A ( -3 , 4 )

Let the second point be B ( x₂ , y₂ ) = B ( 1 , 4 )

Now ,

The equation for the line is given by

y - y₁ = m ( x - x₁ )

To find the slope of the line ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values , we get

m = ( 4 - 4 ) / 1 - ( - 3 )

m = 0

So , the slope of the line is 0

Now ,

The equation of line will be

y - 4 = 0 ( x - ( -3 ) )

y - 4 = 0

Adding 4 on both sides , we get

y = 4

So , the equation of the line is y = 4

Grandma's age is 6 years less than 5 times Junior's age, j. If Grandma is 64 years old, which equation
can be used to find Junior's age?

Helppp

Answers

Answer:

junior is 6

Step-by-step explanation:

take 64 and divide by 5 you get 12 then take away the 6 years and you get juniors age which is 6

The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say Grandma's age is G while junior is J.

As per the given,

Grandma's age is 6 years less than 5 times Junior's age,

G = 5J - 6

64 = 5J - 6

J = 14

Hence "The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old".

Hi, could i please get some help with this I forgot the formula for it..... THANKS!!

Answers

Answer:

b = 12

Step-by-step explanation:

a² + b² = c²

a and b are the length of the sides in the right triangle and c is the hypotenuse.

since we know one leg and the hypotenuse, we can find the other leg.

9² + b² = 15²

81 + b² = 225

b² = 225 - 81

b² = 144

b = 12

Answer:

The answer is 12

Step-by-step explanation:

the formula is A^2+B^2=c^2

9² + b² = 15²

81 + b² = 225

b² = 225 - 81

b² = 144

b = 12

Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!!
