Answer:
1. 501
2. 1258 or 4258 or 9258
Step-by-step explanation:
1. represent number (d3d2d1) in terms of x. let x = 10's digit (dxd) then
d2 = x
d1 = x + 1
d3 = 5(x + 1) = 5x + 5
d3 + d2 + d1 = 6
(5x + 5) + (x) + (x + 1) = 6
7x + 6 = 6
7x = 0
x = 0 SO
d3 = (5x + 5) = 5
d2 = 0
d1 = x + 1 = 1
501
2. d4d3d2d1 and d1 not = d2 not = d3 not = d4, let d3 = x and d2 = y then
d2 = y
d3 = x
d1 = 4x and d1 = y + 3 so 4x = y + 3 or y = 4x - 3
d4 = perfect square (1 or 4 or 9)
any d must be <= 9
d4d3d2d1 = (1 or 4 or 9)(x)(4x - 3))(4x) so x<3 (0,1,2) or d1 fails <= 9
(1,4,9)(0,1,2)((4x - 3 = (1,5))((4x = 0,4,8)
d3 (0,1,2) must be 2 because 0 does not work for d2 and 1 does not work for d1, so this make d1 (4x) = 8 so
(d4)(2)(4x - 3 = 5)(4x = 8) = d4 (1,4,9) and 258 so
1258 or 4258 or 9258
You can represent the measures of an angle and its complement as x⁰ and (90-x)⁰. Similarly, you can represent the measures of an angle and its supplement as x⁰ and (180-x)⁰. Use these expressions to find the measures of the angles described.
14 .The measure of an angle is equal to the measure lf its complement.
[tex]\large \mathfrak{Solution : }[/tex]
From the above statement we can assume an angle and its complement as x and (90° - x)
now, it's goven that the angle and it's complement are equal, so
x = 90° - x2x = 90° x = 45°i hope it helped...
Let the angle be x
Its complement=90-xATQ
[tex]\\ \sf\longmapsto x=90-x[/tex]
[tex]\\ \sf\longmapsto x+x=90[/tex]
[tex]\\ \sf\longmapsto 2x=90[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{90}{2}[/tex]
[tex]\\ \sf\longmapsto x=45[/tex]

9514 1404 393
Answer:
h = 3V/A
Step-by-step explanation:
Multiply by h to get it out of the denominator.
Ah = 3V
Divide by the coefficient of h to get it by itself.
h = 3V/A
_____
Whatever you do to one side of the equation must also be done to the other side. When we say "multiply by h", you should understand that to mean "multiply both sides of the equation by h."
This rule, "do the same thing to both sides of the equation," is the property of equality that makes Algebra work.

jillian measured the mass of her empty backpack and found it to be 0.428 kilogram. which shows a way to represent the value of the 8 in this number?
F. (8x 1/100)
H. (8x 1/1,000)
G. (8x 1/10)
J. (8x 0.01)
Which inequality represents all values of x for which the quotient below is
defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B.x great than or equal to 1
O C. x> 1
O D. x<-1
You can re-write this quotient this way :
[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1

The graph of y=f(x) is graphed below. What is the end behavior of f(x)?
Answer:
The first choice
Step-by-step explanation:
What are the coordinates of the point
3/4 of the way from a to b
Answer:
(-3.5,1.25)
Step-by-step explanation:
A is at -5,-4 and B is at -3,3
using the slope formula the slope has to be 3.5
meaning 3/4ths of the way is a translation of 1.5 right and 5.25 up making the coordinates (-3.5,1.25)

5(3r+11)=85
I'm confused on how to do this, and if i'm doing it right. Do I times the 5 by the 3 and then by the 85 so its on both sides? Ah! I don't know what im doing...
Answer:
r = 2
Step-by-step explanation:
Actually, there are 2 ways to solve this equation.
The first one:
5( 3r + 11) = 85
so here, you have to multiply 5 by ( 3r + 11) and maintain the 85
15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side.
15r = 85 -55..... remember that the sign of 55 will change from positive to negative
15r = 30.... now divide both sides by 15
15r/15 = 30/15
r = 2
The second method :
5 ( 3r + 11) = 85...... divide both sides by 5
5 (3r + 11) / 5 = 85/5
3r + 11 = 17
3 r = 17 - 11
3r = 6
r = 2
I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)
Answer:
r = 2
Step-by-step explanation:
5(3r + 11) = 85
~Use distributive property
15r + 55 = 85
~Subtract 55 to both sides
15r = 30
~Divide 15 to both sides
r = 2

Yes, the set of points is a function.
Step-by-step explanation:
A function only passes through any given y value once. None of the y values (the second number in the form (x, y)) are the same, so the set of points is indeed a function.
