How do you solve linear equations

2 answers:

8 0

Y=mx+b if you mean graphing

m=rise/run or slope
b=your y intercept in linear equations they have them or you rearrange/get the y (which is at the start of the problem) alone. then you graph like say..

y=2x+1

you would rise 2 and go right 1 and you start on 1 on the y intercept of graph

A membership committee of three is formed from four eligible members. Let the eligible members be represented by A, B, C, and D.

yKpoI14uk [10]

The correct statement is:

There are four ways to choose the committee.
There are three ways to form the committee if person D must be on it.
If persons B and C must be on the committee, there are two ways to form the committee.

It is given that:

A membership committee of three is formed from four eligible members.

1) There are four ways to choose the committee.

This statement is true.

Since we have to choose 3 members out of the 4 members so we can use the method of combination.

2) There are three ways to form the committee if person D must be on it.

This statement is also true.

Since D has to be in the committee, this means we have to choose 2 more people out of the three people to form the committee.

3) If seven members are eligible next year, then there will be fewer combinations.

This statement is wrong.

Since we have to choose 3 members out of 7 members so the number of possible combinations will be:

There are 35 combinations possible.

4) If persons B and C must be on the committee, there are two ways to form the committee.

If B and C have to be in the committee then we have to choose just one person out of the two people left.

Hence, the statement is true.

5) If persons A and C must be on the committee, then there is only one way to form the committee.

If A and C have to be on the committee then as in the last option we have to choose any one of the two-person left.

So possible number of ways is 2.

Hence, the statement is false.

What is the value of x? what is the value of y? type in an integer or decimal

Vilka [71]

9514 1404 393

Answer:

x = 5.6
y = 65

Step-by-step explanation:

There are a couple of relations that are applicable to these questions.

the product of segment lengths of crossed chords is the same for both chords
the angle formed at crossed chords is the average of the intercepted arc measures

The segment lengths relation tells us ...

10x = 8×7 . . . . . . products of segment lengths are equal

x = 56/10 = 5.6 . . . . divide by 10

The value of y° is the average of the intercepted arcs:

y° = (85° +45°)/2 = 65°

_____

Additional comment

This diagram does not have enough information to allow computation of z. We would need to know the intercepted arc, or the length of the secant that meets tangent z.

Find the factored form of -7y - y2 = 0

miskamm [114]

Answer:

-y(7+y) =0

Step-by-step explanation:

-7y - y^2 = 0

Factor out a -y

-y(7+y) =0

Using the zero product property

-y =0 and 7+y =0

y=0 7-7+y = 0-7

y=0 y = -7

. Ralph’s Fill Dirt and Croissant Shop in Spencer makes both grand and petit croissants. Each grand requires 1 ounce of flour an

Gwar [14]

Answer:

Step-by-step explanation:

let G be the number of grand croisssants, and P the number of petit croissants :

we have that 1 ounce of flour and 2 ounces of butter result in one G.

additionally, we have that 1/4 ounce of flour and 1/3 ounce of butter result in one P.

Ralph has 4 ounces of flour and 6 ounces of butter, If he bakes more than 1 G then he will never use all of his ingredients!, let's see:

1 G:

he now has 3 ounces of flour, and 4 ounces of butter,

now we need to figure out how many P's we would obtain with such amounts:

let x be the number of P's

$1/4*x = 3=>x=12\\ 1/3*x=4=>x=12$

which is reasonable, Ralph can bake 12 P's,

now with more than 1 G:

2G:

Ralph has now 2 ounces of flour and 2 ounces of butter, now we have to figure out that x is the same using the remaining ingredients

$1/4*x = 2=>x=8\\ 1/3*x=2=>x=6$

This is impossible.

3G:

he runs out of butter.

There is the answer, he is able to bake 1 grand croissant and 12 petit croissants

Write the equation in the slope-intercept form. 7x − 4y + 8 = 0

slega [8]

7x - 4y + 8=0 slope intercept is y=mx+b so you have to get y alone
+4y =+4y so add for y on both sides
7x + 8=4y Then divided 4y on both sides
7x/4 8/4= 4y/4
slope intercept form is y=7/4x+2
