Solve for x.
2x2 + x = 10

Solve For X.2x2 + X = 10

Answers

Answer 1

Answer:

x = 2, x = -5/2

Step-by-step explanation:

2x² + x - 10 = 0

(2x + 5)(x - 2) = 0

2x + 5 = 0

2x = -5

x = -5/2

x - 2 = 0

x = 2

Solve. Your solution needs to have the variable first. -4 + x < -10

Answers

Answer and Step-by-step explanation:

First off, we need to get the variable by itself. We do this by adding 4 to each side of the inequality.

x < -6

Our answer is x < -6, so all values that are inputted to x and are less than -6 are solutions to the inequality.

How much ice can fill a cooler?

(Volume is a measure of the inside contents or the space inside)
b - how much juice fits in a juice box
d - how much sand fills the sandbox
e - how much ice fills cooler

volume is how much space something takes up, not covers

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing?

a) Ja’quan read the thermometer wrong
b) He must have observed hail falling from thunder clouds
c) It was cold enough to allow solid precipitation to fall
d) Children were most likely throwing ice

State the slope and y-intercept for the graph of the equation -8x + y = -12.

Show your work!!

Answers

Answer:

Slope is 8 and Y-Intercept is -12

Step-by-step explanation:

Move the -8x over to the right side by adding it, You are now at

y=-12+8x

Move these around and you are now at

Y=8x-12

Answer:

Step-by-step explanation:

Remark

y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.To read the slope, you must have x and its coefficient on opposite sides of the equal sign. So you get y = 8x - 12 when you add 8x to both sidesNext, the y intercept is found when x = 0y = 8x - 12y = 8(0) - 12y = - 12The  y intercept is -12 or in point form (0, - 12)

Answer

slope = 8

y intercept = - 12

Caterers made 272 cups of punch for a party. They will distribute the punch equally into 6 bowls. How many cups of punch will each bowl have? A. B. C. D.

Answers

Answer:

45.33 cups.

Step-by-step explanation:

272 divided by 6 gives this answer

The number of cups of punch each bowl will have is given by the equation A = 45.3 cups

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of cups of punch in each bowl be represented as A

Now , the equation will be

The total number of cups of punch = 272 cups

The number of bowls = 6 bowls

So , the number of cups of punch in each bowl A = total number of cups of punch / number of bowls

Substituting the values in the equation , we get

The number of cups of punch in each bowl A = 272/6

The number of cups of punch in each bowl A = 45.3 cups

Therefore , the value of A is 45.3 cups

Hence , the number of cups in each bowl is 45.3 cups

determine the domain of the following graph

Answers

Answer:

[-5, 10) or you can write [tex]-5\le x < 10[/tex]

Step-by-step explanation:

The domain is the set of all values of x used in the function. Scan across the graph from left to right (much as you do when reading). The first point you find on the graph has an x-coordinate 5 (see the solid dot?). Then, as you continue reading across the graph, there are values of x used until you get to 10. The dot at x = 10 is open, not filled in. That indicates that the number x = 10 is NOT used by the function.

So the domain is all real numbers greater than or equal to -5 and less than 10.

[-5, 10) is called interval notation; a square bracket means the value next to it IS used by the function, a parenthesis means the value next to it is NOT used.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease per unit
of x, to the nearest tenth of a percent.

The triathlon involves the bike race, swimming and the marathon.

You are given the distance for the marathon, the biking and the total distance.

Total distance = Swimming + Marathon + Biking

135.7 = Swimming + 23.5 + 110

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm. Find the approximate increase in the surface area of the cylinder when the radius of the base increases to 5.05

Answers

Answer:

19.72 cm²

Step-by-step explanation:

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.

The volume of cylinder is given by :

[tex]V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2[/tex]

When r = 5.05, new volum becomes,

[tex]V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2[/tex]

Increase in area = 1000.97 - 981.25 = 19.72 cm²

So, the increase in surface area of the cylinder is equal to 19.72 cm².
