Is p = -1 a solution to the equation 6(p – 4) = -30p?

jenyasd209 [6]

To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.

</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)

</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5

</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30

-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.

Hope this helps!</span>

Let xij = gallons of component i used in gasoline j. Assume that we have two components and two types of gasoline. There are 8,0

Mnenie [13.5K]

Answer:

option c) x₁₁ + x₁₂ = 8000

Step-by-step explanation:

Given:

xij = gallons of component i used in gasoline j

gallons of component 1 available = 8,000

demand gasoline types 1 = 11,000

demand gasoline types 2 = 14,000

Here, we have only component 1 available i.e i = 1 only

( therefore, all the options containing i = 2 gets eliminated )

thus,

component 1 will fulfill the demand of gasoline types 1 and 2 i.e j = 1 and 2

hence,

the equation satisfying the above conditions comes out as:

x₁₁ + x₁₂ = 8000

that means gallons of component 1 used in gasoline 1 and 2 and the total equals to the gallons of component 1 available i.e 8000

Please help..not too sure on how to work this out.

lina2011 [118]

Answer and Step-by-step explanation:

Ok, it's basically just parts of a circle circumference and area equation. Let's start first by writing down both equations.

C = 2πr

C = πd

A = π $r^{2}$

Now, all we have to do is plug in the values into those equations!

4. C = 2π(12) A = π( $12^{2}$ )

r = 12

d = 24 <---- (12 times 2 equals 24)

C = 24π

A = 144π <---- (12 times 12 (itself) equals 144)

5. C = π4.8 A = π( $4.8^{2}$ )

r = 2.4 <------- (4.8 divided by 2 equals 2.4)

d = 4.8

C = 4.8π

A = 23.04π <------- (4.8 times 4.8 equals 23.04)

6. 20π = 2πr A = π $r^{2}$

r = 10 <------- (20π divided by π and divided by 2)

d = 20 <------- (20π divided by π)

C = 20π

A = 100π <------- (10 times 10 equals 100)

7. C = 2πr 81π = π $r^{2}$

r = 9 <------- (81π divided by π and square rooted equals 9)

d = 18 <------- (9 times 2 equals 18)

C = 18π <------- (2 times 9 equals 18, times π)

A = 81π

A single gram of a certain metallic substance has 0.52 grams of copper and 0.26 grams of zinc. The remaining portion of the subs

Vitek1552 [10]

First of all, if we have 1 gram of a substance that has 0.52 gram of copper and 0.26 gram of zinc, the remainder will be:

Since we know that the remaining portion of the material is nickel, we have 0.22 gram of metal.

Now, Ben estimates that 1 gram of the substance has 0.2 gram of nickel. To find how many grams of metal are in 35 grams of the material, we are going to multiply the grams of the substance by the gram of nickel:

We can conclude that according to Ben, 35 grams of the content has 7 grams of metal.

But we know that in 1 gram of the substance are not 0.2 gram of nickel but 0.22. So let's multiply the grams of the material by 0.22 to find the actual grams of nickel in it:

We can conclude that 35 grams of the substance have 7.7 grams of metal.

The following mapping statements describe the transformation of the vertices of △ABC to the vertices of its image, △A′B′C′. A(0,

victus00 [196]

Answer:

C. a reflection in the y-axis

Step-by-step explanation:

The mapping statement for the transformation of the vertices of the triangle ABC is given as following:

A(0,2)→A'(0,2)

B(2,9)→B'(-2,9)

C(4,2)→C'(-4,2)

To find the correct transformation for the given statement.

Solution:

From the given statements, the general transformation statement for the the vertices of the triangle can be given as:

$(x,y)\rightarrow (-x,y)$

The above transformation shows a reflection in the y-axis as the transformation in y-axis changes the sign of the x-coordinate of the point.
