Answer:

  see below

Step-by-step explanation:

The positive/negative information tells you the x-intercept is (-8, 0). The y-intercept information tells you the y-intercept is (0, 4). Those two points are sufficient to let you draw the graph with a drawing tool.

__

A "linear function" is a straight line. This one goes through the points listed above.

What are the solutions of the equation x4 + 95x2 – 500 = 0? Use factoring to solve. x = plus-or-minus StartRoot 5 EndRoot and x
Oduvanchick [21]

Answer:

<em>* x ⇒ plus-or-minus StartRoot 5 EndRoot and ±10i *</em>

Step-by-step explanation:

Through factorization;

x^4 + 95x^2 – 500 = 0, ⇒ <em>u^2 ⇒ x^2</em>,

u^2 + 95u - 500 = 0, ⇒<em> factors of -500; -25, 20, -50 * 10, -2 * 250, -5 * 100...</em>

( u )^2 + ( - 5 + 100 ) + ( - 5 * 100 ) = 0,

( u - 5 )( u + 100 ) = 0,

<em>u = 5, and y = - 100</em>

Substitute u back into format x^2;

u = x^2, 5 = x^2, | x | = √5 ⇒ <em>x = - / + √5,</em>

u = x^2, - 100 = x^2, | x | = √- 100 ⇒ <em>x = - / + 10i</em>

<em>* Answer: x ⇒ plus-or-minus StartRoot 5 EndRoot and ±10i *</em>

Solve the system of equations.<br> y= 3x<br> y= x2-10
svetoff [14.1K]

Answer:

(-5, 2) and (2, 6)

Step-by-step explanation:

Use the substitution method. We know that y = 3x and y = x^2 - 10, so we can set them equal to one another.

3x = x^2 - 10

x^2 - 3x - 10 = 0

Use the quadratic equation to solve for x.

x = - 5, 2

Now solve for y using these two values of x by substituting it back into the equations.

y = - 15,  6

In coordinate form, (-5, 2) and (2, 6)

Each bowl can hold 1/4 cup of nuts. Taisha has 3 3/8 cup of nuts. How many full bowls can she make?
aksik [14]

Answer:

13 bowls

Step-by-step explanation:

To figure out how many bowls of nuts she can make, we divide how many cups of nuts she has by how many cups of nuts in a bowl

3 3/8 ÷ 1/4

Lets change 3 3/8 into an improper fraction

3 3/8 = (8*3 +3)/8 = 27/8

27/8 ÷ 1/4

Copy dot flip

27 /8 * 4/1

27/2

2 goes into 27 13 times with 1 left over

13 1/2

She will have 13 full bowls of nuts

\sqrt[4]{3. \sqrt[4]{432}}
= \sqrt[4]{3. \sqrt[4]{2^4.3^3} }
= \sqrt[4]{3.2.3^\frac{3}{4}}
= 3^\frac{1}{4}.2^\frac{1}{4}.3^\frac{3}{16}
= 3^\frac{7}{16}.2^\frac{1}{4}
