Answer:

The error is the slope is -4 and the correct is, the slope is $-\frac{1}{4}$

Step-by-step explanation:

You must put the equation in the form of y = m x + b, where

m is the slope

b is the y-intercept

Let us put the equation n the form above

∵ x = -4y

→ Switch the two sides

∴ -4y = x

→ Make the coefficient of y equal 1 by divide both sides by -4

∵ $\frac{-4y}{-4}$ = $\frac{x}{-4}$

∴ y = $\frac{x}{-4}$

→ Write $\frac{x}{-4}$ as $-\frac{1}{4}$ x

∴ y = $-\frac{1}{4}$ x

→ Compare it by the form above

∴ m = $-\frac{1}{4}$ and b = 0

∴ The slope of the is $-\frac{1}{4}$ , and the y-intercept is 0

∴ The error is the slope is -4 and the correct is the slope is $-\frac{1}{4}$

Answer:

0.6

Step-by-step explanation:

6x - 3 = x + 7

6x + 3 = x + 3

6x = x + 10

6x = 10

6 ÷ 10 = 0.6

x = 0.6

Which is bigger? 1/3 foot or 5 inches? It can also be equal.

zhannawk [14.2K]

5 inches is bigger than 1/3 foot OR 1/3 foot is lesser than 5 inches. That is, 1/3 foot < 5 inches

4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards

8 yards is equal to 24 feet. That is, 8 yards = 24 feet

<h3>Calculating the value of a quantity </h3>

From the question, we are to determine which of the given quantities are bigger or equal

1/3 foot or 5 inches

NOTE: 1 foot = 12 inches

If 1 foot = 12 inches

Then,

1/3 foot = 1/3 × 12

1/3 foot = 4 inches

∴ 5 inches is bigger than 1/3 foot. That is, 1/3 foot < 5 inches

4 miles or 7,000 yards.

NOTE: 1 mile = 1760 yards

If 1 mile = 1760 yards

Then,

4 miles = 4 ×1760 yards

4 miles = 7040 yards

Hence, 4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards

8 yards or 24 feet

NOTE: 1 yard = 3 feet

If 1 yard = 3 feet

Then,

8 yards = 8 × 3 feet

8 yards = 24 feet

Hence, 8 yards is equal to 24 feet. That is, 8 yards = 24 feet

From the sum of 3a^2−ab−2b^2 and 2a^2+5ab−3b^2 subtract a^2−3ab−4b^2

Lubov Fominskaja [6]

$(3a^2-ab-2b^2) + (2a^2+5ab-3b^2) - (a^2-3ab-4b^2)$

First we distribute the negative throughout the last polynomial:

$(3a^2-ab-2b^2) + (2a^2+5ab-3b^2) + (-a^2+3ab+4b^2)$

Combine like terms:

$4a^2 + 7ab - b^2$

Answer:

Interval estimate for the proportion of all homeowners in the United States that hold a home equity loan lie between (.17033 , .22967 ) or 17% to 22.9%

Step-by-step explanation:

Given -

In a recent poll of 1,200 homeowners in the United States, one in five homeowners reports having a home equity loan that he or she is currently paying off.

If one in five homeowners reports having a home equity loan then for 1200 homeowners = $\frac{1200}{5}$ = 240 homeowners reports having a home equity loan.
