Answer: will be A

Step-by-step explanation:

Answer:

The weights are 50 lb, 35 lb, and 35 lb.

Step-by-step explanation:

The three boys weight x, y, and z pounds.

One boy weighs 50 lb, so x = 50. The other 2 boys have the same weight, so y = z.

The average weight is the sum of the three weights divided by 3.

(x + y + z)/3 = 40

(50 + y + y)/3 = 40

2y + 50 = 120

2y = 70

y = 35

z = y = 35

Answer: The weights are 50 lb, 35 lb, and 35 lb.

Answer: 35 lb, 35 lb, and 40 lb

Step-by-step explanation:

(50+X+X)/3 = 40

50 + 2X = (40)(3)

2X = 120 - 50

X = 70/2

X = 35

The required coordinate of B will be at (1, 4)

When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;

[tex]M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ][/tex] where:

[tex]X =\frac{x_2+x_1}{2} \\Y=\frac{y_2+y_1}{2}[/tex]

From the question, we are given the following coordinate points

[tex]X=1\\x_1=1\\[/tex]

Get x₂;

[tex]X =\frac{x_2+x_1}{2}\\1 =\frac{x_2+1}{2}\\2=x_2+1\\x_2=2-1\\x_2=1\\[/tex]

Get y₂;

[tex]Y =\frac{y_2+y_1}{2}\\2 =\frac{y_2+0}{2}\\2 \times 2=y_2+0\\4=y_2+0\\y_2=4\\[/tex]

Hence the coordinate of B will be (1, 4)

Answer:

-infinity < y ≤ 2

Step-by-step explanation:

A is correct.  The largest value y can have is 2, whereas there is no smallest value.   -infinity < y ≤ 2

The range of the given graph will be -∞ ≤ y ≤ 2. The correct option is A.

The collection of all a function's outputs constitutes its range. Example: Let's take a look at the function f: AB, where f(x) = 2x and A and B each represents a collection of natural numbers. The domain in this instance is A, and the co-domain is B. The range then appears as the function's output.

The range of the function is -∞ ≤ y ≤ 2. When we move towards the left side the value of y reaches negative infinity and when we move to the right the value of y reaches the value of 2.

It means that the range of the function is varying from negative infinity to a positive value of 2.

Answer:

Greatest common factor (GCF) of 36 and 210 is 6.

Step-by-step explanation:

Answer:

6

Brainliest, please! (Almost an Ace!)

Step-by-step explanation:

Look at the smallest factor, 36. Find its factors.

36: 1, 2, 3, 6, 12, 18, 36

Out of all of them, which is the biggest one that 126 and 210 are also divisible by?

We see that they're divisible by 1, 2, 3, and 6.

Our answer is 6.

All of the numbers below 1000 are going to give us negative number answers. For all of them, we just subtract 1000 from it to see how much over or below we are.

16. Analyze

An integer is just a number with no fraction or semi-value that is part of it. So 7 and -10 are integers while -1.5 and 2/3 are not.

A negative integer is one below zero, and a positive is one above zero.

PART A: Letters a and c represent the negative integers because they are to the left of zero on the number line.

PART B: letters b and d represent the positive integers because they are above zero on the number line.

PART C: They can be described as additive inverses, which have a different sign but the same absolute value (distance from zero). They are called this because when you combine them you get zero.

Answer: C . 147π / 4 mi²

Concept:

The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.

A = (θ / 360) πr²

θ = angle of the sector

π = constant

r = radius

Solve:

Given variable

θ = 270°

r = 7 mi

Given formula

A = (θ / 360) πr²

Substitute values into the formula

A = (270 / 360) π (7)²

Simplify exponents

A = (270 / 360) π 49

Simplify by multiplication

A = (147 / 4) π

A = 147π / 4

Answer:

(- 1, - 6 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula

Use this formula on the endpoints and equate to the coordinates of the midpoint.

let the other endpoint = (x, y) , then

[tex]\frac{13+x}{2}[/tex] = 6 ( multiply both sides by 2 )

13 + x = 12 ( subtract 13 from both sides )

x = - 1

[tex]\frac{-2+y}{2}[/tex] = - 4 ( multiply both sides by 2 )

- 2 + y = - 8 ( add 2 to both sides )

y = - 6

The coordinates of the other endpoint are (- 1, - 6 )

Answer:

( − 2 , 2 )

Step-by-step explanation:

Add 2 x to both sides of the equation.

y = 6 + 2 x 5 x + 3 y = − 4

Replace all occurrences of y with 6 + 2 x in each equation.

Replace all occurrences of y in 5 x + 3 y = − 4 with 6 + 2 x . 5 x + 3 ( 6 + 2 x ) = − 4 y = 6 + 2 x

Simplify the left side.

11 x + 18 = − 4 y = 6 + 2 x

Solve for x in the first equation.

x = − 2 y = 6 + 2 x

Replace all occurrences of x with − 2 in each equation.

y = 2 x = − 2

The solution to the system is the complete set of ordered pairs that are valid solutions. ( − 2 , 2 ) The result can be shown in multiple forms.

Point Form: ( − 2 , 2 )

Equation Form: x = − 2 , y = 2
