What is the equation for the line in slope-intercept form?
Enter your answer in the box.

Answers

_________the answer is -4+5_________

First, spot 2 coordinates that are found on the line. Let’s take (0,5) and (-2,13).

To find the slope use formula: (y2-y1)/(x2-x1). We get : (13-5)/(-2-0) = 8/-2 = -4

For equation of line we know y=mx+b where m is the slope and b is the y-intercept. We know m=-4. So we have:

y = -4x+b

To find b, we just replace one of the coordinates for x and y. Let’s take (0,5)

5 = -4(0)+b
b=5

So the equation of the line is:

y = -4x+5

can someone please help me figure out what X is? I've tried starting with different numbers and stuff, but I don't know what to do​

Step-by-step explanation:

20:30 = 2:3 = 1:1.5

18×1.5 = 27

27 = 2x +11

16 = 2x

find the value of the variable and BC, if B is between A and C.
AB = 5x, BC = 3x-1, AC = 47

Answers

Answer:

17

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

47 = 5x + 3x - 1

Combining like terms:

47 = 8x - 1

Add 1 on both sides:

48 = 8x

Divide 8 on both sides:

X = 6

Now that we know what X equals, we can solve BC.

BC = 3(6) - 1

BC = 18 - 1

BC = 17

Therefore BC = 17.

Answer:

Y=-1

Step-by-step explanation:

Substitute 30 into x, now the equation is

y = 14 -0.5(30)

Now solve the RHS for the answer.

y = -1

we have to substitute x as 30 so replace the equation as

y=14-0.5(30)

Multiply 0.5(30) first

Then you have

y=14-15

So subtract that two and you’ll get a negative one

2/3x - 2 = 3/7 rewrite without fractions

Answers

0.67x-2=0.428 that is the approximation

The value of the expression in can be estimated by using LCM and algebraic rules and it comes 3.64.

How given expression can be rewrite or simplified?

To rewrite the equation 2/3x - 2 = 3/7 without fractions, we need to eliminate the fractions by multiplying both sides of the equation by the least common multiple (LCM) of the denominators.

The denominators in this equation are 3 and 7, and their LCM is 21. So, we will multiply both sides of the equation by 21:

21 x (2/3x - 2) = 21 x (3/7)

Simplifying the left-hand side, we distribute the 21 to both terms:

14x - 42 = 9

Adding 42 to both sides, we get:

14x = 51

Finally, dividing both sides by 14, we get

x = 3.64 (rounded to two decimal places)

Therefore, the equation 2/3x - 2 = 3/7, rewritten without fractions, is 14x - 42 = 9. The solution to the equation is x = 3.64.

Do NOT answer just for points.​

Answers

Answer:

y+4=-3(x+1)

Step-by-step explanation:

point slope form = y-y1=m(x-x1)

so plug in the numbers

y - -4 = -3 (x - - 1)

if there are two negatives it becomes a positive so your final answer is y + 4 = -3 (x +1)

Answer:

x+y = 1

x = 3, y = -2

Step-by-step explanation:

Given the expressions

x-y = 5

x²-y² = 5

From 2:

x²-y² = 5

(x+y)(x-y) = 5 .... 3

Substitute equation 1 into 3;

(x+y)(5) = 5

Divide both sides by 5

x+y = 5/5

x+y = 1

b) To deduce x and y, we will solve the equation below simultaneously

x-y = 5

x+y = 1

Add both equations

x+x = 5+1

2x = 6

x = 6/2

x= 3

Substitute x = 3 into equation 1

Recall from 1:

x-y = 5

3-y = 5

y = 3-5

y = -2

Hence x = 3, y =-2

Therefore, the equation only has one solution which is x=32

Answer:

This question has 1 solution.

Step-by-step explanation:

Solve for X

First, distribute:

6x - 48 +10 = 5x - 6

Second, combine like terms:

6x - 38 = 5x - 6

Third, move like signs to one side:

Answers

the answer is b: 40 miles in 5 hours
solution: simplify both numbers by the gcf
40/5=8
5/5=1
8:1

Answer: B) 40 miles for 5 hours

Divide both values by 5 and we'll simplify that to 8 miles for 1 hour. This is the same as saying 8 miles per hour, or 8 mph.

The ratio 8:1 is read as "8 to 1", meaning the first value is 8 times that of the second value. Note how 40 is 8 times that of 5, ie 40 = 8*5.

What is the y-intercept of this line: y= 7x-5

Answers

Answer:

- 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x - 5 ← is in slope- intercept form

with y- intercept c = - 5

The y-intercept of the line y = 7x - 5 is -5.

To find the y-intercept of the line represented by the equation y = 7x - 5, we need to determine the value of y when x is equal to zero. The y-intercept represents the point where the line crosses or intersects the y-axis.

In this case, when we substitute x = 0 into the equation, we get:

y = 7(0) - 5

y = -5

Therefore, the y-intercept of the line y = 7x - 5 is -5. This means that the line intersects the y-axis at the point (0, -5), with the y-coordinate being -5. Graphically, this indicates that the line crosses the y-axis at a height of -5 units.
