Mathematics
1 answer:
NISA [10]3 years ago
3 0

Answer:

-0.4 = −2/5

Step-by-step explanation:

Rewrite the decimal number as a fraction.

-0.4/1

Multiply to remove 1 decimal places.

-0.4/1 x 10/10 =4/10

Find the GCF.

4 ÷ 2/10 ÷ 2 = 2/5

x = 2/5

-2/5

Which linear equation best represents the data given in the table?
kirill115 [55]

Linear equations are equations that have constant slopes

The linear equation that represents the table is (a) y = 7x +4

<h3>How to determine the linear equation</h3>

Start by calculating the slope (m) using:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{-10 +17}{-2 +3}

Simplify

m = \frac{7}{1}

m = 7

The equation is then calculated as:

y = m(x -x_1) + y_1

So, we have:

y = 7(x +2) -10

Open the brackets

y = 7x +14 -10

y = 7x +4

Hence, the linear equation that represents the table is (a) y = 7x +4

What is the solution of sqrt (x-4)+5=2
worty [1.4K]

Answer:

x = 13

Step-by-step explanation:

<em>sqrt (x-4) + 5 = 2</em>

<em>The equation is √(x+4) + 5 = 2</em>

√(x-4) = 2 - 5

√(x-4) = -3

x-4 = (-3)²

x-4 = 9

x = 9 + 4

x = 13

Therefore, the second option x = 13 is correct.
