7x+2y=47
5x-4y=1
use elimination method
Answer:
x=5, y=6
Step-by-step explanation:
7x+2y=47
5x-4y=1
to use elimination method , you want to add the two equations together so that either x or y cancels out. For these equations, we will multiply the first equation by 2. (This will cancel out y value)
2(7x+2y)=2(47)
14x+4y =94
————————
add above equation to second equation:
14x+4y=94 above equation
5x-4y=1 second equation
19x=95 added together
x=5
—————————————
‘solve for y by substituting x value (5) into either original equation
5x-4y=1
5(5)-4y=1
25-4y=1
-4y=-24
y=6

use the difference of two squares to find the value of 612 - 392
Answer: 4 (153 - 98)
formula is a^2-b^2=(a+b)(a-b)
factor out the GCF:
4(153−98)
both terms are not perfect squares so
you cant factor it further.

Your soccer team is holding a silent auction dinner as a fundraiser to pay for school uniforms. The list shows all the expenses for the silent auction.
A tablet that costs $350
Football tickets that cost $150
A gift card that cost $125
The cost of the food is $500
The members of the soccer team will be selling tickets to the silent auction. A ticket to the silent auction includes chances to win prizes and dinner. The ticket cost is set so that 45 tickets will pay for the cost of the prizes and food.
Build a function that can be used to find the total profit, f(x), the soccer team earns by selling x tickets. Show your work to build this function.
Answer:69
Step-by-step explanation:
A) $16
B) p(x) = 16x -800
C) 69 ticketsn:
A) The total of expenses is ...
$280 +100 +20 +400 = $800
If this is covered by 50 tickets, then a ticket must provide revenue of ...
$800/50 = $16
The cost per ticket is $16.
__
B) The profit is the difference between revenue and expenses. The revenue from sale of x tickets will be 16x. The expenses are fixed at 800, so the profit is ...
p(x) = 16x -800
__
C) We can find the number of tickets to sell (x) in order for profit to be at least $300 by solving the inequality ...
p(x) ≥ 300
16x -800 ≥ 300 . . . . . use the expression for p(x)
16x ≥ 1100 . . . . . . . . . add 800
x ≥ 68.75 . . . . . . . . . . divide by 16 . . . (the least satisfactory integer is 69)
In order to raise at least $300, the number of tickets sold must be at least 69.

Answer:
1. C 3.D 4.D
Step-by-step explanation:
1. The chances of getting a white marble is 3/9 so the chances of not drawing it is 6/9
3. The theoretical probability is 10/50. The experimental probably turned out to be 8/50. So the theoretical probability is bigger meaning its D.
4. 18/24 is 75%, 75% of 300 is 225

What are Factors of a Number?
Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder
Given data ,
The number = 42
The number has both negative and positive factors
The factors of the number 42 are
The positive factors of 42 are 1 , 2 , 3 , 6 , 7 , 14 , 21 , 42
The negative factors of 42 are -1 , -2 , -3 , -4 , -6 , -7 , -14 , -21 , -42
Product of -14 and -3 = -14 x -3
= 42
Sum of -14 and -3 = ( -14 ) + ( -3 )
= -17
Hence , -14 and -3 are the two factors of 42 which has as a sum of -17

Which is the equation of a parabola with vertex (0,0) and directrix y= 4
a. Y^2 = -8x
b. Y^2 = -16x
c. X^2 = -8y
d X^2 = -16y
Answer:
D. [tex]x^{2} = -16\cdot y[/tex]
Step-by-step explanation:
The vertex form of the equation of the parabola centered in the origin, with axis of symmetry in the x-axis and directrix in the first and second quadrants is described by the following formula:
[tex]4\cdot p \cdot y = x^{2}[/tex], [tex]p < 0[/tex] (1)
Where:
[tex]y[/tex] - Dependent variable.
[tex]x[/tex] - Independent variable.
[tex]p[/tex] - Focus distance.
If we know that vertex is located at (0, 0) and the directrix pass through (4, 0), then the focus distance (distance of the vertex with respect to that point) is -4, and the equation of the parabola is [tex]x^{2} = -16\cdot y[/tex].
Hence, the right choice is D.

Vienna bought 8 yards of fabric and paid $35.60. How many more
yards can she purchase with $20?
(The paper this is one is due tmr. Help)
Answer:
4.49 more yards
Step-by-step explanation:
Given data
If 8 yards of fabric cost $35.60
then let x yards cost $20
cross multiply
35.60*x= 20*8
35.60*x= 160
x= 160/35.60
x= $4.49
Hence the $20 will purchase 4.49 more yards
9. Find DP
please help!!!!!!
Answer:
DP = 15.
Step-by-step explanation:
I am assuming that DP EP and FP are peroemdicular bisectors of the sides of ABC.
D is the midpoint of AB so
2x + 14 = 8x - 52
14+52 = 8x - 2x
6x = 66
x = 11.
So side AD = 2(11) + 14 = 36.
Now PC = PA = 39.
So by pythagoras:
DP^2 = AP^2 - AD^2
= 39^2-36^2 = 225
DP = sqrt 225
= 15.

I make $8 dollars per hour (H) for babysitting. I make a total (T) dollars babysitting on Saturday. In the space below, identify the Independent Variable (either H or T), the Dependent Variable (either H or T), and write an equation based on this information (include 8, H, T, and an = sign).
Answer: 8H=T
Step-by-step explanation:
8 is dependant on the hours so you put it together. Your independent
value is T since it is by itself. So your answer becomes.
