Which of the following sets shows all the numbers from the set {0, 0.5, 1, 2.5, 3} that make the inequality 2a + 3 ≥ 8 true?

{2.5, 3}
{1, 2.5, 3}
{0, 0.5, 1}
{0.5, 1}

Answers

Answer 1

Answer:

A

Step-by-step explanation:

it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)

Answer 2

Answer:

{2.5, 3}

Step-by-step explanation:

2a + 3 ≥ 8

2a + 3 - 3 ≥ 8 - 3

2a ≥ 5

[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]

a ≥ 2.5

From the expression above, a is equal to 2.5 and any number above 2.5

∴The answer is {2.5, 3}

Answers

Answer:

he expression 14 - 0.6t represents remaining fuel in the vehicle, where t represents number of days. ... A warning light comes on when the remaining fuel is 1.5 gallons or less.

Step-by-step explanation:

Okay do first what you wanna do is combine common like terms in this case the common like terms are 2x and 4x and since 2x is a negative and 4x is a positive you would want to subtract which gets you 2x then you add 6 and 5 because they are both constants and they are both positive when you add it will get you 11 so it will be 2x +11

10. Which equation below is equivalent to 3x + 2y = -2?
a. y = -2/3x – 5
b. y = 3/2x + 7
c. y = -3/2x - 1 d. y = 2/3x + 4
e. NOthing

Answers

Answer c, you have to put the equation in slope intercept form which is y=Mx+b so you would subtract the 3x and move it to the other side of the equal sign before the -2 so it would be 2y=-3x-2 then you would divide the 2 on both sides to separate the 2 from the y. -3x/2 is -3/2x 2/-2 is -1 so you answer would be C y= -3/2x - 1 Hope this makes since! Good luck!

Rectangle is a polygon with four sides , Opposite side of the polygon are parallel and equal.

It is given that

The letter will be 42 cm tall and 33 cm wide.

Each bar of the letter will have a thickness of 8 cm.

The letter H will be made from three rectangular bar

The standing rectangular bar have dimensions of 42 cm * 8 cm

The horizontal rectangular bar will have

Length = 33 - 8 - 8 = 17  cm

Width = 8 cm

Therefore the amount of duct tape required will be equal to the area of the rectangle

Area of the rectangle = 42 * 8 + 42  * 8 + 17 * 8

Area of the rectangle = 808 sq.cm

Area of the duct tape required = 808 sq.cm.

Is this math or algebra?

What is the value of _a_ in the equation below?

2a + 3 = 4a + 5

Answers

Step-by-step explanation:

hope it is helpful to you

Step-by-step

Simplifying 2a + 3 = 4a + 5

Reorder the terms: 3 + 2a = 4a + 5

Reorder the terms: 3 + 2a = 5 + 4a

Solving 3 + 2a = 5 + 4a

Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.

Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a

Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1

Answers

Answer:

Reflection: A' (5, 3)

                B" (4, 6)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)
