Step-by-step explanation:
Evaluate $3x^y + 4y^x$ when $x=2$ and $y=3$.
Answer:
60
Step-by-step explanation:
Given,
x = 2
y = 3
3x^y + 4y^x
= 3 ( 2 )^3 + 4 ( 3 )^2
= 3 ( 8 ) + 4 ( 9 )
= 24 + 36
= 60

Answer:
money market: $1000stock: $238,500mutual fund: $228,500Step-by-step explanation:
We can let x and y represent the amounts invested in the stock and mutual fund, respectively. Then the amount invested in the money market account was (468000 -x -y). Two relations can be written.
x = y + 10000 . . . . . 10,000 more was invested in stock than in mutual funds
0.035(468000-x-y) +0.04(x) -0.03(y) = 2720 . . . . first-year return
Collecting terms in the second equation gives ...
0.005x -0.065y +16380 = 2720
-x + 13y = 2732000 . . . . . . subtract 16380, multiply by -200
12y -10000 = 2732000 . . . . substitute for x using the first equation
y = 2742000/12 = 228,500 . . . . solve for y
x = 228,500 +10,000 = 238,500 . . . . . find x from the first equation
468,000 -x -y = 468,000 -467,000 = 1,000 . . . . find the money market amount

Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?
Answer:
Car A: 8 minutes
Car B: 6.67 minutes
Step-by-step explanation:
Car A: 60km evrery hour so,
1 km every minute, so he will be in 8km in 8 minutes.
Car B: 72km per hour so,
72/60 = 1.2 = 1.2 km per minute.
8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.
Answer:
40 min
Step-by-step explanation:
Car A is traveling at 1 km/min (60/60)
Car B is traveling at 1.2 km/min (72/60)
Car B gains .2km on Car A for every minute they drive.
8km/.2 = 40

Answer:
Amount they ate is 6/8 or 3/4 of the pizza
Amount left over is 2/8 or 1/4 of the pizza.
Step-by-step explanation:
your family at 6 out of 8 pieces and simplified thats 3/4 if you divide both by 2
so the pieces left over would be 2 pieces or 2 out of the 8 pieces are left over.
making your fraction 2/8
Now you simplify and you can divided both 2 and 8 by 2
Making your other fraction 1/4

Step-by-step explanation:
The area of a right triangle is 36 square
meters. The height is twice as long as
the base.
To find the area of a triangle, use the
1
following formula:a bh
2
where b is the base and h is the height.
How long is the shorter leg of the triangle?
Answer:
6 m
Step-by-step explanation:
36 m^2 = bh/2
36·2 = bh/2·2
72 = bh
72 = 12·6
check
36 m^2 = 12·6/2
36 = 36

Answer:
y = 3x -8
Step-by-step explanation:
The point-slope form of the equation of a line can be a useful place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +20 = 3(x +4) . . . . with given numbers filled in
y = 3x +12 -20 . . . . eliminate parentheses, subtract 20
y = 3x -8 . . . . . . . . slope-intercept form

Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?
Answer:
she bought 70 shares of the $15 shares
she bought 20 shares of the $20 shares
Step-by-step explanation:
this would be solved using simultaneous equation
let a = $15 shares
b = 20 shares
a + b = 90 equation 1
15a + 20b = 1450 equation 2
Multiply equation 1 by 15
15a + 15b = 1350 equation 3
subtract equation 3 from equation 2
5b = 100
b = 20
substitute for b in equation 1
20 + a = 90
a = 70

Answer:
Rise=2 Run=1 type of slope is positive slope is 2 y int is 1 and the equation is y=2x+1
Step-by-step explanation:
1. First you need slope, slope is y1-x1/x2-y2 so then you get 4/2 which is 2, we also know rise/run so rise is 2
2. 2/1 so run is 1
3. its positive since slope is positve
4. y int is when x is 0 and y has value so y int is 1
5. y=2x+1 since slope and y int

To multiply a decimal number by 102, move the decimal point
Answer:
two digits to the right
Step-by-step explanation:
When multiplying a decimal by 102 you would need to move the decimal point two digits to the right. This is because we are multiplying by a hundred number. When multiplying any whole positive number by a decimal, we need to move the decimal point to the right one less than the amount of digits that the positive whole number has. For example, a thousand (1000) has 4 digits so we move the decimal point of the product to the right by 3.
Examples:
102 * 0.02 = 2.04
1000 * 0.02 = 20
10000 * 0.02 = 200

A glass holds 1over6 liter of liquid.How many glasses of liquid are in 4 liters
Answer:
24 glasses
Step-by-step explanation:
If a glass holds 1/6 liters of liquid, that means that 6 of them can hold one liter
1/6 * 6 = 1
and if 6 of them can hold 1 liter, that means 24 of them can hold 4 liters
6 * 4 = 24
