2x2−3x−4=0

For this equation: a=2, b=-3, c=-4

2x2+−3x+−4=0

Step 1: Use quadratic formula with a=2, b=-3, c=-4.

x=

Answer:

a. days                         1        2        3     4       5

number of gallons    12      24     36    48    60

b.     g = 12d    (the number of days times 12)

c.    a person uses 84 gallons of water for showering each week.

Step-by-step explanation:

each day is 12 gallons so just multiply the number of days by 12 to get how many gallons that you use in a set number of days. for the last one, a week is 7 days so if you do 7 x 12 then you get how many gallons a person uses in a week.

Answer:

  1.1 quarts

Step-by-step explanation:

Let x represent the amount to be added, in quarts. Then the amount of anti-freeze in the resulting solution is ...

  0.20(8) + 1.00(x) = 0.30(8 +x)

  0.70x = 0.10(8) . . . . . . subtract 0.20(8)+0.30(x)

  x = 8/7 . . . . . . . . . . . . . divide by the coefficient of x

  x ≈ 1.142857 ≈ 1.1

About 1.1 quarts of pure antifreeze must be added.

Answer:

Step-by-step explanation:

for this graph  find rise over run ,  and where the line crosses they y axis.. sooo ..

it crosses at -2 and  the slope is rise over run  or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1

sooo...

use the slope intercept form   y = mx + b

y = 1x + (-2)

y = x - 2   :)

4/10 + 2/10 = 6/10

there are 4/10 left after planting which can be reduced by 2 = 2/5

Answer:

No, it is 3/5

Step-by-step explanation:

Because you divide by 2  for both bottom and top of  the fractions and you will get 1/5, and 2/5 and you add them together and you get 3/5.

Answer:

16x²

Step-by-step explanation:

since all sides of a square are equal, we just multiply 4x by 4x. this gives us 16x².

The area of square with side length 4x is 16x.

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.

Given,

The side length of a square is 4x

We need to find the area of square.

As we know that area of square = 4a.

Where a is the length of side of a square.

In a square all the four sides will have same length.

a=4x

Area of square=4(4x)

=16x

Hence the area of square with side length 4x is 16x.

Answer:

x = 11

Step-by-step explanation:

Given that,

The slope of the line, m = 3/4

First point = (x,2)

Another point = (3,-4)

We need to find the value of x.

The slope of a line is given by the formula as follows :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put x₁ = x, y₁ = 2, x₂ = 3, y₂ =-4 and m = 3/4

Put all the values,

[tex]\dfrac{3}{4}=\dfrac{-4-2}{3-x}\\\\3(3-x)=4(-6)\\\\9-3x=-24\\\\9+24=3x\\\\33=3x\\\\x=11[/tex]

So, the value of x is 11.

Answer:

B

Step-by-step explanation:

Rise is 4/3x means that the point (4,3) will be on the line, and b is the only one which has (4,3).

Which line has a constant of proportionality between y and x (Slope) of 4/3?

4/3 = slope = rise over run

(Rephrase) Which line has a slope of 4/3? Go up 4 over 3 from the origin (since there is no y-intercept)

Only B goes up 4 and over 3 (has the slope of 4/3)

Answer: B
