Answer:
1.99 * 10^4
Step-by-step explanation:
Here, we want to write the addition in standard form
= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)
= 10,000 + 9000 + 900
= 19,900
so the number in standard form is;
1.99 * 10^4

Answer:
The slope is 2
Step-by-step explanation:
Solve by factoring. Check your answer.
[tex]x^2-4x=0[/tex]
Please show all work. Thanks!!!
Answer:
x=0 or x=4
Step-by-step explanation:
Lets Solve!
First we need to factor the left side of the equation. Both terms include x.
[tex]x^2-4x =0[/tex]
[tex]x(x-4) =0[/tex]
If we multiplied x by (x-4) we would be back at [tex]x^2-4x =0[/tex].
Set factors equal to 0.
x=0 or x−4=0
x=0 or x=4
Woohoo! Brainliest Appretiated! Hope I helped!
Answer:
[tex]x=0,4[/tex]
Step-by-step explanation:
Factor out the common terms from x²-4x. You can factor out x:
[tex]x(x-4)=0[/tex]
Multiplication can be seen as (_)(_). Rewrite:
[tex](x)(x-4)=0[/tex]
Set both equal to 0:
[tex]x=0\\\\x-4=0[/tex]
Simplify the second equation:
[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]
So, x=0 or x=4

y+3=2(x+5), write the equation of the line in slope intercept form.
Answer:
slope intercept form: y=mx+b
y+3=2(x+5)
step 1: use distributive property
y+3=2(x)+2(5)
y+3=2x+10
step 2: subtract 3 on both sides to make y by itself
y+3=2x+10
-3 -3
final answer: y=2x+7

slope from two points
Answer:
[tex]\frac{12}{7}[/tex]
Step-by-step explanation:
use the formula [tex]\frac{y - y'}{x - x'}[/tex]
so you would get
[tex]\frac{4 - (-8)}{0 - (-7)}[/tex]
Those negatives becomes a positive and you get 4+8 = 12 and 0+7 = 7
you final answer would be [tex]\frac{12}{7}[/tex]
Answer: I am pretty sure the answer is D.
Step-by-step explanation:
so this is how u find the slope from two points... You have (-7,-8) and (0,4) you then take -7 and subtract that by 0 so -7-0 and then -8-4. and -7-0/-8-4 = 7/12. plz tell me if I am wrong.
what is the slope perpindicular to line 5x+3
Answer:
[tex]-\frac{1}{5} x+b[/tex] (b can equal any number- you can use 3)
Step-by-step explanation:
To find the slope, you take mx (in this case 5x), get the number by itself, flip the sign, then get the reciprocal.
5 -> -5 -> [tex]-\frac{1}{5}[/tex]

Constant
Variable
Answer:
in -7y y is variable and -7 is Constant
Step-by-step explanation:
Constant: A number that cannot change its value. In the expression 2x+4y−9 , the term 9 is a constant. Like Terms: Terms that contain the same variables such as 2m , 6m or 3xy and 7xy
variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set.
The ratio of boys to girls in a camp is 6 to 8. How many girls are there in the camp if there are 96 boys in the camp?
Answer:
128 girls
Step-by-step explanation:
The ratio of boys to girls is 6 to 8. We need to find how many girls there are if there are 96 boys in the camp. One way to solve this is by using cross multiplication:
[tex]\frac{6}{8}[/tex] = [tex]\frac{96}{x}[/tex]
multiply the 6 by the x: 6x
multiply 8 by 96: 768
6x = 768
divide both sides of the equation by 6 to isolate the x:
6x/6 = 768/6
x = 128
When there are 96 boys in camp, there will be 128 girls.
Answer:
6/8=96/x
Step-by-step explanation:
Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde.
This hall, in which he was now left alone, was a pet fancy of his friend the doctor’s; and Utterson himself was wont to speak of it as the pleasantest room in London. But tonight there was a shudder in his blood; the face of Hyde sat heavy on his memory; he felt (what was rare with him) a nausea and distaste of life; and in the gloom of his spirits, he seemed to read a menace in the flickering of the firelight on the polished cabinets and the uneasy starting of the shadow on the roof. He was ashamed of his relief, when Poole presently returned to announce that Dr. Jekyll was gone out.
Which statement best describes how the author establishes mood in the excerpt?
a.The author’s description of the grand room creates an admiring mood.
b.The author’s description of physical symptoms creates an anxious mood.
c.The author’s mention of Utterson’s thoughts creates a sentimental mood.
d.The author’s mention of Utterson’s spirits creates a spiritual mood.
Answer:
b.The author’s description of physical symptoms creates an anxious mood.

can someone please help me with math
Answer:
[tex]x = 71[/tex]
Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
[tex]180 - 40 - 31 = 109[/tex]
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
[tex]180 - 109 = 71[/tex]
Now we know x is 71

Answer:
D.) j
Step-by-step explanation:
J because if in one month there is $32 and then in 2 months there are $64 its multiplying 32 times 2 and that gets 64 then 64 plus 32 is 96 then plus 32 again and that gives you 128. Its multiplying 32 times 2 then 32 times 3 then 32 times 4 and that gives you your answer.

If, In 2010 the Network Club membership was 2,500. With an annual growth rate of approximately 8%, compounded continuously, then 5563.85 is the population in 2022.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
In 2010 the Network Club membership was 2,500.
Annual growth rate of approximately 8%
8% is converted to decimal value by dividing 8 with 100
8/100=0.08
