21 is your answer

Hope this helped!

Answer:

The value of the function for f(-5) is 21.

Step-by-step explanation:

Consider the provided function.

[tex]f(x)=|2x-1|+10[/tex]

We need to find the value of the function for f(-5).

Substitute the value of x=-5 in the above function.

[tex]f(-5)=|2(-5)-1|+10[/tex]

[tex]f(-5)=|-10-1|+10[/tex]

[tex]f(-5)=|-11|+10[/tex]

The absolute value of -11 is 11.

[tex]f(-5)=11+10[/tex]

[tex]f(-5)=21[/tex]

Hence, the value of the function for f(-5) is 21.

Hello,

Let's look at the equation: 3(x−7)=6(x−10). Let's distribute the 3 and 6 to the parenthesis. After you distribute, the equation should look like: 
3x - 21 = 6x - 60. Then add 21 to both sides and that should leave you with 
3x = 6x - 39. Let's then get 6x to the other side by subtracting 6x to both sides. That'll leave you with -3x = -39, then divide each side by -3 to get x by itself. The equation would now be: x = 13. Hope this helps =).

is the choice vertical angle theorem correct?

Answers

Unfortunately it is incorrect. You should instead go for the Alternate Exterior Angle Theorem

Angle 2 and angle 7 are on opposite or alternate sides of the transversal cut. They are also exterior because they are on the outside of the train tracks (think of line a and line b as the metal rail of the train tracks). If a || b, then the alternate exterior angles are congruent, which applies to angle 2 and angle 7. Also it applies to angle 1 and angle 8.

Mayumi is constructing a line through point P that is perpendicular to RS←→. A horizontal line segment R S and a point P are drawn. The point P is above the horizontal line segment R S. She places her compass on point P to construct an arc. What must be true about the width of the compass opening when Mayumi draws the arc? It must be greater than 12RS. It must be equal to PS . It must be wide enough so that the arc intersects RS←→ in two points. It must be equal to PR .

Answers

Width of the compass should be more than the smallest space between P and RS, so that it cuts RS at two distinct points. Therefore, it must be wide enough so that the arc intersects RS←→ in two points. The photo is attached so that you can understand it more.

The current diameter of a tree trunk is 10 inches. the trunk diameter increases at a rate of 2 inches per year. an insect burrows into the trunk and lays its eggs in the secondary xylem, 1 inch out from the center of the tree. how far from the center will the dormant eggs be located in two years?

Answers

The answer is 1 because tree trunks grow wider because of cell divisions that occur only in the vascular and cork cambia (both located underneath the bark). Secondary xylem (wood) remains in place once it is formed. Therefore, the eggs will remain in their current position (1 inch out from the center).
the answer would be "1".

What is an expression?

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Opposite of eleven = negative of eleven

Opposite of eleven = -11

Twice = multiply by two

So,

Twice the opposite of eleven = 2(-11) = -22

Hence "Twice the opposite of eleven will be 2(-11)".

The product of two numbers is 44. find the sum of the two numbers s(x) as a function of one of the numbers, x. s(x)

Answers

Call the numbers x and y. According to the first sentence, xy = 44. You can rearrange to solve for y: y = 44/x. The sum of the numbers, s(x), is x + y, but we just found a way of expressing y in terms of x. Therefore: the sum expressed as a function of one of the numbers (x) is:

s(x) = x + 44/x

Answers

[ -4, 5 ]

notice the brackets, as opposed to parentheses.

the brackets mean, -4 is a bound and it is included in the range, and 5 is the other bound and 5 is also included in the range too.

so, whatever number "x" is, we know that is between -4 and 5, so it could be -3, -2, 1, 4 or such.

keeping in mind that, for the negative side of the numbers, the closer to 0, the greater the number, therefore, -4 is greater than -5 and is also greater than -1,000,000, because -4 is closer to 0 than those two.

so, "x" is greater than -4, and includes it, but is also less than 5, but it can be 5 too.
