Answer:
x intercept: 3
y intercept: 10
Step-by-step explanation:
look at the axises, the line goes though one point(the y intercept) and touches the other point(the x intercept)
Answer:
x-intercept = (3,0)
y-intercept = (0, 9)
Step-by-step explanation:
FIND Y-INTERCEPT y = (x - 3)^2 (Set x to 0)
y = (0 - 3)^2; y = (-3)^2; y = 9/y-intercept is (0,9)
FIND X-INTERCEPT y = (x - 3)^2 (Set y to 0)
0 = (x - 3)^2; 0 = x^2 -6x + 9; −x^2 + 6x − 9 = 0; (−x + 3)(x − 3) = 0;
−x + 3 = 0 or x − = 0; x = 3 or x = 3/x-intercept is (3,0)

I had $80.45 in my bank account on Monday. I deposited $20.50 on Tuesday, Wednesday, and Thursday. I then withdrew $37.25 on Friday. How much money is in my account for the weekend? $
Answer:
$104.70
Step-by-step explanation:
The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3) would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.
Answer:
$104.70.
Step-by-step explanation:
If you started with $80.45, and then deposited $20.50 3 times, one for Tuesday, Wednesday, and Thursday, that would get you up to $141.95. Then, if you withdrew $37.25 on Friday, that leaves you with $104.70 for the weekend.
1.2mg to mcg converted
Answer:
1200 mcg
Step-by-step explanation:
Formula = mg multiply by 1000
1.2 mg × 1000
= 1200 mcg
How to Convert Milligrams to Micrograms
1 milligram (mg) is equal to 1000 micrograms (μg).
1 mg = 1000 μg
The mass m in micrograms (μg) is equal to the mass m in milligrams (mg) times 1000:
m(μg) = m(mg) × 1000
1.2 milligrams is equal to 1200 micrograms.
We have,
The prefix "milli-" in milligrams indicates a thousandth (1/1000), and the prefix "micro-" in micrograms indicates a millionth (1/1,000,000).
To convert from milligrams to micrograms, we need to multiply the value in milligrams by a conversion factor of 1000, as there are 1000 micrograms in 1 milligram.
In this case,
We have 1.2 milligrams (1.2 mg) that we want to convert to micrograms.
We can set up the conversion as follows:
1.2 mg x (1000 mcg/1 mg)
By multiplying 1.2 mg by the conversion factor (1000 mcg/1 mg), the milligram units cancel out, leaving us with the desired unit of micrograms. The calculation is:
1.2 mg x (1000 mcg/1 mg) = 1200 mcg
Therefore,
1.2 milligrams is equal to 1200 micrograms.
The conversion factor of 1000 was used because there are 1000 micrograms in 1 milligram.

yesny had $240 to spend on five pairs of jeans. How much did each pair of jeans cost if she has $10 left
Answer:
$46
Step-by-step explanation:
Let each pair of jeans cost $x.
Total sum of money= cost of 5 pairs of jeans +amount left
[tex]240 = 5x + 10[/tex]
-10 on both sides:
[tex]5x = 240 - 10[/tex]
Simplify:
[tex]5x = 230[/tex]
Divide by 5 on both sides:
[tex]x = \frac{230}{5} \\ x = 46[/tex]
Thus, each pair of jeans cost $46.
Answer:
$46
Step-by-step explanation:
240-10=230 divided by 5= 46

slope of 3/2? PLEASE HURRY NEED ANSWER
Answer:
[tex]f(x)=\frac{3}{2}x+4[/tex]
Step-by-step explanation:
The Slope-Intercept Form equation is f(x)=mx+b
m= slope
b= y-intercept
you are already given the slope ([tex]\frac{3}{2}[/tex]), so you only have to find the y-intercept.
first, plug in the x of the point given (-6) into the equation
[tex]\frac{3}{2}[/tex](-6)=-9
then you find the difference of the answer and the y of the given point (-5)
-5-(-9)
-5+9=4

Mike is 4 years older than his sister Olivia. together they are 20 years old. How old is Olivia?
I’ll give Brainly if you get it right! :)
Answer:
Olivia is 24 years old
step by step
because Olivia is 20 years old and Mike is 4 years older than her so Olivia is 24 years old
Answer: Olivia is 8 years old.
Step-by-step explanation:
"O" stands for Olivia
O+4 = M
O + O+4 = 20
2O +4=20
2O=16
2O/2 = 16/2
O = 8
Mike is 4 years older, so Mike is 12 years old
12+8 = 20

One number is 16 less than 4 times the second number. Their sum is 29. Find the numbers.
Answer:
20,9
Step-by-step explanation:
this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x
The system of equations are x + y = 29 and y = 4x - 16
The two numbers are 9 and 20 respectively
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be x
Let the second number be y
Now , the equation will be
One number is 16 less than 4 times the second number
So , y = 4x - 16 be equation (1)
And , Sum of the numbers is 29
So , x + y = 29 be equation (2)
And , y = 29 - x be equation (3)
Substituting the value of y from equation (3) in equation (1) , we get
29 - x = 4x - 16 be equation (4)
On simplifying the equation , we get
Adding x on both sides of the equation , we get
5x - 16 = 29
Adding 16 on both sides of the equation , we get
5x = 45
Divide by 5 on both sides of the equation , we get
x = 9
Substituting the value of x in equation (2) , we get
y = 20
Therefore , the two numbers are 9 and 20

A tuna Hunter is swimming on top of the water when he shoots at tuna fish with his spear gun. If the hunter shoots at a 24° angle depression and he uses 200 feet of chord to spear the fish how deep was the fish? (Please help me i need to turn this in now)
Answer:
The fish is approximately 81.35 feet down
Step-by-step explanation:
Notice that the 200 ft chord at a 24 degrees angle of depression means that you are dealing with a right angle triangle, where the chord is the hypotenuse, and the fish's depths is the side opposite the 24 degree angle. So you can use the definition of the sine function in a right angle triangle:
[tex]sin(\theta)=\frac{opposite}{hypotenuse} \\sin(24^o)=\frac{x}{200} \\x = 200 \,*\,sin(24^o)\\x \approx 81.35\,\,ft[/tex]

(2x+2x)+(7-1)
4x+6
The total horizontal length of the two rooms combined is 4x+6
Multiply this with the vertical length (x+3) getting
(4x+6)(x+3)
y(x+3) .... see note below
y*x + y*3
x(y) + 3(y)
x(4x+6) + 3(4x+6)
4x^2+6x + 12x + 18
4x^2+18x+18
which is the total area of both rooms combined
Note: I replaced (4x+6) with y in step 2 above. That helps with distribution though it's not mandatory. You could also use the FOIL rule or the box method as alternative options.
Another alternative option is to find the area of each individual room and then add up the two smaller areas to get the larger total area.
