Which could be used to evaluate the expression -6(4 2/3)?
Answer:
The answer is A
-6[4 2/3]
= -6[4+2/3] because 4 2/3 is 4 and 2/3rds
so a(b+c) = a(b) + a(c)
so -6(4) + -6(2/3)

A triangle has three angles 5x, 9x and 4x. as described below. Find the value of x
and the value of each angle.
Answer:
the value of x=10°
Step-by-step explanation:
hey there!
as there is given angles of the triangle i.e. 5x,9x,4x
now adding all of them,
5x +4x+9x=180 (reason: sum of angle of a triangle is 180°)
18x=180
x=180/18
x=10
therefore the value of x is 10
now the value of each angle is;
5x= 5*10=50
4x=4*10=40
9x=9*10=90
hope it helps! thank u!!!

In evaluating the limits of rational functions, the numerator and the denominator was found out to be both equal to zero, what does it mean?
Answer:
If only numerator found as zero the answer would be zero. If only denominator found as zero the answer is undefined. In your situation both are zero. But, when denominator becomes zero the answer always be undefined. Therefore, your answer is undefined when both numerator and denominator are zeros.

Find two numbers whose product is -6 and whose sum is 1.
Answer:
-2, 3
Step-by-step explanation:
yeah that's it I don't have any explanation or formula
let the numbers be x and y
xy = -6
x + y = 1
from x + y = 1
y = 1 - x
x(1 - x) = -6
x - x² + 6 = 0
-x² + x + 6 = 0
on solving,
x = -2 or x = 3
y = 1 - (-2) = 3
y = 1 - 3 = -2
x1 = -2, y1 = 3.
x2 = 3, y2 = -2.

You multiply two integers. You increase one of them by 1 and decrease the other
by 1. The product increases by 6. What integers could you have multiplied?
Integers are numbers without decimals
The integers could you have multiplied are 9 and 2
Let the numbers be x and y
So, we have:
[tex]\mathbf{x \times y}[/tex]
Increase x by 1 and reduce y by 1.
So, we have
[tex]\mathbf{(x +1) \times (y -1) = 6 + xy }[/tex]
Open brackets
[tex]\mathbf{xy -x + y - 1 = 6 + xy}[/tex]
Subtract xy from both sides
[tex]\mathbf{ -x + y - 1 = 6}[/tex]
Collect like terms
[tex]\mathbf{ -x + y = 6 + 1}[/tex]
[tex]\mathbf{ -x + y = 7}[/tex]
Rewrite as:
[tex]\mathbf{ y -x= 7}[/tex]
The above means that, the difference between the integers is 7.
There are several integers that fit the above description;
One possibility is: 9 and 2

Answer:
x = 1.5 or x = 0.5Step-by-step explanation:
Given equation:
4x² - 8x + 3 = 0Find the discriminant:
D = b² - 4ac = (-8)² - 4*4*3 = 16The roots are:
x = (-b ± √D)/2a = (8 ± √16)/(2*4) = (8 ± 4)/8 = 1 ± 1/2x = 1.5 or x = 0.5So
x=(8±√8²-4²(3))/2(4)x=(8±√64-48)/8x=(8±4)/8x=1±1/2So
x=3/2 or 1/2

A little boy accidentally let go of his balloon, and it floated away. It was 3 feet above the ground when he let go, and it steadily rose 3 feet per second. Write an equation that shows the relationship between the number of seconds since the boy let the balloon go, x, and its elevation in feet, y.
The equation that shows the relationship between the number of seconds since the boy let the balloon go is y = 3x + 3.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A little boy accidentally let go of his balloon, and it floated away. It was 3 feet above the ground when he let go this height is our constant value in the function.

We know that half of QS is x+25 and half of diagonal PR is 2x+5.
We can tell that x+25 = 2x+5 because both of these are sides of an isosceles triangle ORS. Since we know that, we can find out the diagonal QS by finding x.
2x+5 = x+25 => x = 20
Half of diagonal QS = 20 +25
= 45
Then we can double the half of diagonal QS to find out the diagonal QS.
45 x 2 = 90
