The slope of the line that contains the points (-2, -1) and (3, 19) is 4. Find the y-intercept.
A. -7
B. -2
C. 2
D. 7

Answers

Answer 1

Answer:

B

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 )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using (4, 10 ) , then

10 = 12 + c ⇒ c = 10 - 12 = - 2 → B

D

Given m = 4 then

y = 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 19 ), then

19 = 12 + c ⇒ c = 19 - 12 = 7 → D

Explain how to find the quotient of 1/4 divided by 5

Answers

Answer:

1/20

Step-by-step explanation:

(1/4) / 5

When dividing a fraction by a whole number

multiply the divisor by the number

4 * 5 = 20

(1/4) / 5 = 1/20

Answer:

Convert 1/4 to decimal form, which is 0.25.Divide 0.25 by 5 The quotient is 0.05, or 1/20 in simplified fraction form

There is another way to solve without converting:

Set up equation like this: 1/4 x 1/5 (Use KCF if you know how to divide or multiply by fractions. If you don't, use the first method above)1/4 x 1/5 = 1/20The quotient is 1/20

2x+y=22
X-y=5

Answers

Answer:

by using substuton method

2x=22-y

x=22-y/2                     equation (i)

so substuting the value x in x-y=5

22-y/2-y=5

22-y-2y/2=5

22-3y=10

22-10/3=y

12/3=y

4=y

now substitute the value of y in equation (i)

x=22-y/2

=22-4/2

=18/2

=9

therefore ,the value of x is 9 and y is 4

1. A light year is defined as the distance light travels in one year. A galaxy is about 150,000 light years wide. About how many kilometers wide is a galaxy if 1 light year is given below? * 9.46x10^{12}

Answers

Answer: 1.419 * 10¹⁸ km

Step-by-step explanation:

The galaxy in question is 150,000 light years wide.

If 1 km = 9.46 * 10¹² then the width of this galaxy in kilometers is:

= Distance in light years * Conversion factor of light years to kilometers

= 150,000 * 9.46 * 10¹²

= 1,419,000 * 10¹² km

= 1.419 * 10¹⁸ km

Rounding decimals is like rounding whole numbers. 7.92 is closer to 8 right?. Because if you take out the decimal point it would be 792.
