x + y = 5.90
2x + 4y = 16.80

Answers

What are you looking for ?
2+4y(5.90-y)=16.80

We move all terms to the left:

2+4y(5.90-y)-(16.80)=0

We add all the numbers together, and all the variables

4y(-1y+5.9)+2-(16.8)=0

We add all the numbers together, and all the variables

4y(-1y+5.9)-14.8=0

We multiply parentheses

-4y^2+23.6y-14.8=0

a = -4; b = 23.6; c = -14.8;
Δ = b2-4ac
Δ = 23.62-4·(-4)·(-14.8)
Δ = 320.16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
y1=−b−Δ√2ay2=−b+Δ√2a

y1=−b−Δ√2a=−(23.6)−320.16√2∗−4=−23.6−320.16√−8

y2=−b+Δ√2a=−(23.6)+320.16√2∗−4=−23.6+320.16√−8

Answer

The answer is negative 14.

Step-by-step explanation:

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

Han's bank account has a balance that is overdrawn and his account balance is -$13.00. How much would he need to deposit in order to get his bank account balance to $10.00?

Answers

Answer:

Step-by-step explanation:

Formula: -13 + d = 10 (d = deposit)

To get d by itself, add 13 to 10: d = 23

Therefore, you need to deposit $23.00.

Maribeth saved $25 per week. She has saved a total of $600. For how many weeks has Maribeth been saving?

Answers

Answer:

24 weeks.

Step-by-step explanation:

25x = 600

divide both sides by 25 to get:

x = 24

Answer:

24 weeks

Step-by-step explanation:

use y = mx+b

      y = total amount saved = $600

      m = amount saved per week = $25

      x = number of weeks saving = ?

      b is not needed in this problem

600 = 25X

x = 600/25

x = 24

Find all the zeroes of g(x)=4x^4+4x^3-11x^2-12x-3

Answers

Answer:

The zeroes of [tex]g(x)=4x^4+4x^3-11x^2-12x-3[/tex] are [tex]-\sqrt{3}, -\frac{1}{2}, \sqrt{3}[/tex], or approximately [tex]-1.732, -0.500, 1.732[/tex].

Step-by-step explanation:

Graphical calculator way (probably intended)

By inputting the function in a graphical calculator we can see that the roots of the graph of [tex]g[/tex] are about [tex]x=-1.732, x = 0.500, x = 1.732[/tex] (make sure you click on the points of interests).

Algebraic way (probably not intended because of obscure factoring)

Notice that [tex]g(x) = 4x^4+4x^3-11x^2-12x-3 = (2x-1)^2(x^2-3).[/tex] So the roots can be calculated with [tex](2x-1)^2 = 0 \vee x^2 - 3 = 0[/tex], yielding [tex]x = -\frac{1}{2} \vee x = \pm\sqrt{3}[/tex].

About 16 weeks ago, there were 59 mold spores found in a garden. After a few weeks of observation, it is determined that the number of mold spores in the garden is tripling every 8 weeks.

The number of mold spores, M, at any given time in the garden is equal to the product of the initial amount of spores, I, and 3 to the power of n, where n is the number of times the amount of mold spores has tripled.

How many mold spores are in the garden today?

The measure of angle Q is 70 degrees. Find the measure of angle P.

Answers

Answer:

∠ P = 40°

Step-by-step explanation:

Since PQ = PR then the triangle is isosceles and the base angles are congruent, then

∠ R = ∠ Q = 70° , so

∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°

∠ P = 180° - 140° = 40°

What is an equation of the line that contains the point (0, -5) and a slope of 1/4

Answers

Answer:

y=1/4x-5

Step-by-step explanation:

Answer:

y = 1/4x - 5

Step-by-step explanation:

y = mx + b is the equation of a straight line.

m = slope, b = y intercept. (y intercept is the point where the line of the graph crosses the y axis)

(0, -5) is the y intercept (if you were to graph this point, it would be on the y axis, fitting the previous description)

the slope is 1/4

replace each variable in the equation, and you get:

y = 1/4x - 5

is 16/24 equivalent to 2/3

is 10/16 equivalent to ⅔​
