Answer:
A. 1
B. -1
C. 5
Step-by-step explanation:
A. Using the Formula, we get u sub 2 = 9-9+1, which is just 1
B. Using the Formula, we get u sub 3 = 1-3+1, which is equal to -1
C. Using the Formula, we get u sub 4 = 1-(-3)+1, which is just 1+3+1 = 5

How do I find x in this problem, x/5-2/3=3/2
Answer:
x = 38/6
Step-by-step explanation:
x/5 - 2/3 = 3/2
3x - 2x5/3x2 = 3/2
3x-10/6 = 3/2
2(3x-10) = 3x6
6x-20 = 18
6x = 18+20
6x =38
x =38/6 or x = 6.33
In July, Clare rode her bike 15 miles in 72 minutes, at her constant speed. a How long did it take her to ride 10 miles? Show or explain your thinking.
Answer: x = 48 minutes
Step-by-step explanation:
15 miles/72 min = 0.208 miles/min
(0.208 miles/min)x = 10 miles
x = 48 minutes
The sum of two numbers is 64 Twice the larger number plus five times the smaller number is 20. Find the two numbers
Answer:
The numbers are 100 and -36.
Step-by-step explanation:
Let x be the larger number
64 - x be the smaller number
x + ( 64 - x ) = 64
2x + 5 ( 64-x ) = 20
2x + 320 - 5x = 20
-3x = -300
x = 100
64 - 100 = -36

State the property that justifies each statement
if y + 6 = 45, then y = 39.
Answer:
Justified ✔
Below is the justification.
Step-by-step explanation:
39 + 6 = 45
=> 45 = 45 ✔
This work justifies that y does equal to 39.

spilled $40 into the ratio of 3:7
Answer:
$12/$28
Step-by-step explanation:
Let x and y represent the two amounts of money adding up to $40.
Assume that x is the smaller amount. Then:
x 3
----- = ----- Remembering that x + y = $40, we get x = $40 - y
y 7
amd sp we have
$40 - y 3
-------------- = ------ which, after cross-multiplication, is $280 - $7y = 3y
y 7
Simplifying this, we get $280 = 10 y, so that y must be $28. If y = $28, x must be $40 - $28, or $12.
$12
Then $40, split in the ratio 3/7, is the ratio ----------------
$28
Check: Note that $12 + $28 = $40, as required, and that $12/$28 = 3/7.

Answer:
Option 3 : 19m, 34m, 15mStep-by-step explanation:
First we must know this,
The length of the third side of a triangle must be less than than the sum of the lengths of any two sides of a triangle.
So, Now let us check one by one :
Option 1 : 5m, 6m, 8m
5 + 6 > 86 + 8 > 55 + 8 > 6So, 5m, 6m, 8m can form a triangle .
Option 2 : 10m, 10, 2m
2 + 10 > 1010 + 10 > 210 + 2 > 10So, 10m, 10m, 2m can form a triangle .
Option 3 : 19m, 34m, 15m
19 + 15 ≯ 34So, 19m, 34m, 15m cannot form a triangle .
Option 4 : 3m, 16m, 14m
3 + 14 > 1616 + 14 > 316 + 3 > 14So, 3m, 16m, 14m can form a triangle .

Answer: 6/5
Step-by-step explanation:
Slope = Rise/ Run
=6/5
Please help me with this homework
Answer:
Option D: [tex]y= -\frac34x+14[/tex]
Step-by-step explanation:
In order for two lines to be perpendicular, the product of the slopes has to be [tex]-1[/tex]. That allows you to rule out A and C. Let's plug the coordinate of the point in B. If the equality holds, we found or line. Else, it's D.
[tex]11 =-\frac34(4) +8 \rightarrow 11 = -3+8 \rightarrow 11=5[/tex] Which is obviously impossible. Our line has to be D
Which slope is perpendicular to slope m= 5/6
Answer:
-6/5
Step-by-step explanation:
The slope of perpendicular lines multiply to -1
5/6 * p = -1
Multiply each side by 6/5
6/5 * 5/6 * p = -1 * 6/5
p = -6/5
The slope of the perpendicular line is -6/5
Carlos bought a new cell phone. The graph represents the
relationship between the number of minutes he uses
and the total
cost. What is the equation of the line?
A) y= 5x + 0.1
B) y=0.1x + 5
C) y=0.5x + 5
D) y = 5x + 5
Answer:
B : y = 0.1x + 5
Step-by-step explanation:
using the y = mx + b equation
b is the intercept on the y axis ( x = 0)
m is the slope of the line.
From the graph we can see that the intercept is (0,5), therefore b = 5;
To calculate slope (m) pick two pints on the line e.g (100, 15) and (0, 5)
m = (y2 - y1)/(x2 -x1) = (15 - 5)/(100 - 0) = 10/100 = 0.1
m = 0.1
therefore in y = mx + b
y = 0.1x + 5

Answer:
g=4, h=2
Step-by-step explanation:
Answer:
[tex]g=4, h=2[/tex]
Step-by-step explanation:
First, put them together. 6g+-6 gets rid of g to leave the rest: 10h=20
Then, just divide 10h by 10 to get h alone. h=2
Plug it in 6g+8h=40
6g+16=40
-16 -16
6g=24
g=4
So the answer is g=4, h=2

= 3 : 4
Answer:
it's 3:4
Step-by-step explanation:
18 ÷ 6 : 24 ÷ 6
3 : 24 ÷ 6

A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is 64 He then walks 68 feet further away and observes that the angle of elevation to the top of the antenna is 43 Find the height of the antenna to the nearest foot.
The height of the radio station antenna is approximately 116 feet to the nearest foot.
From the diagram in the attached image
[tex]h=\text{the height of the radio station antenna}\\x=\text{the distance from the foot of the radio station antenna to where the man stood at first}[/tex]
we now have the following relationships
[tex]tan64^\circ=\frac{h}{x}\\\\\implies x=\frac{h}{tan64^\circ}[/tex]
and
[tex]tan43^\circ=\frac{h}{68+x}\\\\\implies x=\frac{h}{tan43^\circ}-68[/tex]
we can equate the two relationships to eliminate [tex]x[/tex].
[tex]\frac{h}{tan64^\circ}=\frac{h}{tan43^\circ}-68[/tex]
solving for the height of the radio station antenna, [tex]h[/tex], we get
[tex]h=\frac{68\times tan43^\circ \times tan64^\circ}{tan64^\circ -tan43^\circ}\approx 116ft\text{ (to the nearest foot)}[/tex]

If you subtract a negative number from that same number you are taking a negative amount from the negative number you started with which means you are making it more positive. Subtracting a negative number is the same as adding a positive one. Such as (-5) - (-6) = 1.
Answer:
Step-by-step explanation:
If u got two negative number such as (-6)+(-7) your answer will be positive 13.
If u got one negative number and one positive number like (-10)-(5) the answer will be negative like -5
