1) 3x – 2y=-16 Write the slope-intercept form of the equation of each line

raketka [301]

Answer:

y = $\frac{3}{2}$ x + 8

Step-by-step explanation:

The equation of a line in slope- intercept gorm is

y = mx + c

Given

3x - 2y = - 16 ( subtract 3x from both sides )

- 2y = - 3x - 16 ( divide all terms by - 2 )

y = $\frac{3}{2}$ x + 8 ← in slope- intercept form

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

stich3 [128]

Answer:

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.

Step-by-step explanation:

We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

The equation will be of slope-intercept form: $y=mx+b$

where m is slope and b is y-intercept

We are given slope m =-3, we need to find y-intercept b

Finding y-intercept

using slope m=-3 and point (-1, 6)

$y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3$

So, y-intercept b is 3

Now the equation of line having slope m= -3 and y-intercept b = 3 is

$y=mx+b\\y=-3x+3$

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.

2.5(6v-4)=10+4(1.5+0.5)

asambeis [7]

$2.5(6v-4)=10+4(1.5+0.5)\\\\(2.5)(6v) - 2.5(4)=10 + 4(1.5) + 4(0.5)\\\\15v - 10 = 10 + 6+2 \\\\15v - 10 = 18\\\\15v - 10 + 10 = 18 + 10\\\\15v = 18\\\\\frac{15v}{15} =\frac{18}{15} \\\\v = \frac{18}{15}\\\\v = \frac{6\times 3}{5\times 3}\\\\v=\frac{6}{5}\\\\\boxed{\bf{ v = \frac{6}{5} = 1\frac{1}{5}}}$

How do you convert .3125 to 5/16

Lilit [14]

Answer: 625

Step-by-step explanation:

Here are the steps to convert .3125 into fraction form:

First we write .3125 as

.3125

Now we multiply both the numerator and denominator by 10 for each digit after the decimal point:

.3125

.3125 x 10000

1 x 10000

3125

10000

In order to reduce the fraction we find the Greatest Common Factor (GCF) for 3125 and 10000. Keep in mind a factor is just a number that divides into another number without any remainder.

The factors of 3125 are: 1 5 25 125 625 3125

The factors of 10000 are: 1 2 4 5 8 10 16 20 25 40 50 80 100 125 200 250 400 500 625 1000 1250 2000 2500 5000 10000

The Greatest Common Factor (GCF) for both 3125 and 10000 is: 625
