Find a solution of the linear inequality.<br> y&gt;_4x-5
irga5000 [103]

Answer:

(0,0) is among the solutions

Step-by-step explanation:

The given inequality is y\ge4x-5

A solution to this inequality is any ordered pair that satisfies the inequality.

Let us check for x=0 and y=0

We substitute to get:

0\ge4*0-5

0\ge-5....This is true.

Therefore (0,0) is a solution to the given inequality.

There are infinitely many solutions.

Juan sells banana bread by weight. He cuts a 1-lb loaf of banana bread into 6 equal slices. He wants to complete the table showi
Westkost [7]

Answer:

0.1\frac{}{6}

Step-by-step explanation:

When Juan cut a 1 lb loaf of banana bread into 6 slices, the weight of each slice forms a repeating decimal. A repeating decimal is a decimal number with repeating digit/s.

i.e \frac{1}{6} = 0.166666666666666...

To express the total weight for each slice, he should write a bar over 6 to show that the number repeats.

i.e \frac{1}{6} = 0.1\frac{}{6}

Note that \frac{}{6} has expressed that the division has 6 as the repeating digit in the decimal number.

  • Left to Right

Equality Properties

<u>Algebra I</u>

  • Multiple Roots

Step-by-step explanation:

<u>Step 1: Define</u>

x² = 625

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Square root both sides:                    x = ±25

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

x = -25

  1. Substitute in <em>x</em>:                    (-25)² = 625
  2. Exponents:                          625 = 625

Here we see that 625 does indeed equal 625.

∴ x = -25 is a solution to the equation.

x = 25

  1. Substitute in <em>x</em>:                    25² = 625
  2. Exponents:                          625 = 625

Here we see that 625 does indeed equal 625.

∴ x = 25 is a solution to the equation.

(13a² − 6a⁵ − 2a) − (−10a² − 11a⁵ + 9a)
Delicious77 [7]

Answer:

a x (23a+5a^4 - 11)

Step-by-step explanation:

(a x (13a - 6a^4 - 2) + 10a^2 + 11a^5 - 9a

rewite the expression and remove any unnecessary parentheses.

a x (13a - 6a^4 -2) + 10a^2 +11a^5 - 9a

factor the expression.

a x (23a - 6a^4-2+11a^4-9)

connect like terms.

your welcome
