What is the slope- intercept form of 4x+5y=20

True [87]

Answer:

y = -4/5x + 4

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form: 4x + 5y = 20

Step 2: Rewrite

Subtract 4x on both sides: 5y = 20 - 4x
Divide 5 on both sides: y = 4 - 4/5x
Rearrange: y = -4/5x + 4

A delivery truck drives three routes in one day. The first route is 1223 miles long, the second route is 1034 miles long, and th

avanturin [10]

Answer:

$Total = 38\frac{11}{12}\ miles$

Step-by-step explanation:

Given

$First\ Route = 12\frac{2}{3}\ miles$

$Second\ Route = 10\frac{3}{4}\ miles$

$Third\ Route = 15\frac{1}{2}\ miles$

Required

Determine the total miles

$Total = First\ Route + Second\ Route + Third\ Route$

$Total = 12\frac{2}{3} + 10\frac{3}{4} + 15\frac{1}{2}$

Convert to improper fractions

$Total = \frac{38}{3} + \frac{43}{4} + \frac{31}{2}$

Take LCM

$Total = \frac{152 + 129 + 186}{12}$

$Total = \frac{467}{12}$

$Total = 38\frac{11}{12}\ miles$

The equations 8x +4y = 32 and 16x +12y = 72 represent the cost for lunch and dinner for a family eating out on vacation. If x is

Nookie1986 [14]

Answer:

There are 3 adults in the family.

Step-by-step explanation:

The equations 8x + 4y = 32 and 16x + 12y = 72 represent the cost of lunch and dinner for a family in which x is the number of adults and y is the number of children.

We have to find the number of adults or the value of x by solving these equations.

equations are 8x + 4y = 32 -------(1)

16x + 12y = 72 --------(2)

Now we will multiply equation 1 by 3 and subtract it by equation 2.

(16x + 12y) -3(8x + 4y) = 72 - 96

16x + 12y - 24x - 12y = -24

(16x - 24x) + (12y - 12y) = -24

-8x = - 24

8x = 24

x = 3

Therefore, there are 3 adults in the family.
