Find rhe x- and y- intercerpts of the following relationships.(There may be more then one)
[tex]3x^{2} + 2y^2 = 24[/tex]
Answer:
see explanation
Step-by-step explanation:
Given
3x² + 2y² = 24
To find the x- intercepts , let y = 0 in the equation and solve for x
3x² + 2(0)² = 24, that is
3x² = 24 ( divide both sides by 3 )
x² = 8 ( take the square root of both sides )
x = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ← x- intercepts
To find the y- intercepts. let x = 0 in the equation and solve for y
3(0)² + 2y² = 24 , that is
2y² = 24 ( divide both sides by 2 )
y² = 12 ( take the square root of both sides )
y = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ← y- intercepts

Laquan will give each guest at his party ¹⁄₂ of a cake. How many cakes should he order if 17 people are attending his party?
Answer:
9 cakes
Step-by-step explanation:
If each of the 17 people will eat 1/2 of a cake, you would 17*1/2 cakes. This is 17/2, or 8.5. You cannot usually order 8.5 cakes, so you would round up. 9 cakes.
What is x?
3/6=5.5/x
Answer:
x = 11
Step-by-step explanation:
3/6=5.5/x
Cross multiply.
3 * x = 6 * 5.5
x = 2 * 5.5
x = 11

Answer:
Step-by-step explanation:
Apply the slope formula to be sure. The slope formula is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Filling in with our coordinates gives us:
[tex]m=\frac{-2-10}{-2-4}=\frac{-12}{-6}=2[/tex]
The slope is 2. If you don't want to use the slope formula you could just look at the line and pick 2 points the line goes through and use a slope triangle, but that's a bit more difficult to explain without the benefit of being there to point out the idiosyncrasies of it.
A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional
$110 per hour for each hour worked over 35 hours per week. A cashier worked 39
hours one week and 37 hours the second week. Show and explain to the cashier how her salary calculated in this two-week period?
Given :
A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional $110 per hour for each hour worked over 35 hours per week.
To Find :
A cashier worked 39 hours one week and 37 hours the second week.
Show and explain to the cashier how her salary calculated in this two-week period.
Solution :
Week 1 :
For first 35 hours he will get fixed amount i.e $540.
Now, for next four hours he will get $110 per hour.
So, total salary, T = 540 + (110×(39 - 35)
T = $980
Week 2 :
Total salary, T = 540 + ( 110×( 37 - 35 ))
T = $760
Therefore, salary of two week period is $( 980 + 760 ) = $1740.

Fred's art project involves a series of parallel stripes. If he starts by drawing the line 8x+2y=7, select all the equations that could represent lines that could also be drawn for his art project.
Options:
A. [tex]y-1 = 4(x + 8)[/tex]
B. [tex]y = -4x + 15[/tex]
C. [tex]16x + 4y = 9[/tex]
D. [tex]y=-4x[/tex]
E. [tex]4x + 2y = 3[/tex]
Answer:
B. [tex]y = -4x + 15[/tex]
C. [tex]16x + 4y = 9[/tex]
D. [tex]y=-4x[/tex]
Step-by-step explanation:
Given
[tex]8x + 2y = 7[/tex]
Required
Select all equations that could be used.
Equation that could be used in place of [tex]8x + 2y = 7[/tex] must have the same slope.
Calculating the slope of [tex]8x + 2y = 7[/tex]
Make y the subject
[tex]2y = 7 - 8x[/tex]
[tex]y = \frac{7}{2} - \frac{8x}{2}[/tex]
[tex]y = \frac{7}{2} - 4x[/tex]
[tex]y = - 4x + \frac{7}{2}[/tex]
Using y = mx + b
Where
[tex]m = slope[/tex]
The slope is -4
Option A.
[tex]y-1 = 4(x + 8)[/tex]
Open bracket
[tex]y - 1=4x + 32[/tex]
Collect Like Terms
[tex]y - 4x = 32 + 1[/tex]
[tex]y - 4x = 33[/tex]
Make y the subject
[tex]y = 4x + 33[/tex]
The slope of this line is 4;
Hence, it can not be used.
Option B.
[tex]y = -4x + 15[/tex]
The slope of this line is -4;
Hence, it can be used.
Option C.
[tex]16x + 4y = 9[/tex]
Solve for4y
[tex]4y=9 - 16x[/tex]
Solve for y
[tex]\frac{4y}{4} =\frac{9}{4} - \frac{16x}{4}[/tex]
[tex]y =\frac{9}{4} - 4x[/tex]
[tex]y = - 4x + \frac{9}{4}[/tex]
The slope of this line is -4;
Hence, it can be used.
D. [tex]y=-4x[/tex]
The slope of this line is -4;
Hence, it can be used.
E. [tex]4x + 2y = 3[/tex]
Solve for 2y
[tex]2y = 3 - 4x[/tex]
Solve for y
[tex]\frac{2y}{2} = \frac{3}{2} - \frac{4x}{2}[/tex]
[tex]y = \frac{3}{2} - 2x[/tex]
The slope of this line is -2;
Hence, it can not be used.
From the calculations above, equations B, C and D are equivalent

Samantha wants to use her savings of $1,150 to buy shirts and watches for her family. The total price of the shirts she bought was $84. The watches cost $99 each. Choose the inequality that would be used to solve for the maximum number of watches Samantha can buy with her savings.
99 + 84x ≤ 1,150
99x + 84 ≥ 1,150
99x + 84 ≤ 1,150
99 + 84x ≥ 1,150

What is the sign of 3 x y 3xy3, x, y when x > 0 x>0x, is greater than, 0 and y < 0 y<0
Answer:
The sign is negative
Step-by-step explanation:
Given
[tex]Expression = 3xy[/tex]
[tex]x > 0[/tex]
[tex]y<0[/tex]
Required
Determine the sign
The expression can be split into 3 factors
[tex](3) (x) (y)[/tex]
If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:
[tex](+3) (+x) (-y)[/tex]
Leave only signs
[tex](+) (+) (-)[/tex]
[tex]+ * + = -[/tex]
So, we have:
[tex](+*+) (-)[/tex]
[tex](+) (-)[/tex]
[tex]+ * - = -[/tex]
So, we have:
[tex](+) (-) = -[/tex]
Hence, the sign of the expression is negative
Take for instance;
[tex]x = 2[/tex]
[tex]y = -4[/tex]
The expression would be:
[tex]3 *2 * - 4 =-24[/tex] -- negative

slope is 5
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
(4,3) (2,-7)
Put it in the equation of y2 - y1 over x2 - x1
-7-3 = -10 and 2 - 4 = -2 that will give you the fraction of -10/-2
Reduce the fraction and that will give you the answer of 5, slope = 5
In slope-intercept form it would be y - 3 = 5 (x - 4)

You are participating in a "Secret Gift Exchange" with your friends. You set
two price requirements: You can spend less than $30, but you must also
spend more than 20. Write the compound inequality. *
Answer:
FOREVER AND ALWAYS
Step-by-step explanation:
i love you more than you know:( <3
see you someday
The compound inequality which represents the given situation is 20 < x < 30.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say x represents the spend.
As per the given,
You can spend less than $30,
x < 30
You must also spend more than 20.
x > 20
Compound,
30 < x < 20
Hence "The compound inequality which represents the given situation is 20 < x < 30".

Answer:
4 miles in 1/3 houra
Step-by-step explanation:
Which speed is the fastest? Group of answer choices LaTeX:
The formula for speed =
Distance (miles) / Time (hours)
A) 4 miles in 1/3 hours
= 4 / 1/3
= 4 ÷ 1/3
= 4 × 3
= 12 miles per hour
B)1/3 miles in 4 hours
=1/3 miles/4 hours
= 1/3 ÷ 4 miles per hour
= 1/3 × 1/4 miles per hour
= 1/12 miles per hour
C) 1/2 miles in 3 hours
= 1/2 miles / 3 hours
= 1/2 ÷ 3
= 1/2 × 1/3
= 1/6 miles per hour
The fastest speed is A, 4 miles in 1/3 houra

River collects old coins. He has four
less than twice as many rare nickels as
he does rare quarters. I the face value
of the coins is $3.65, Which system of
equations can be used to find n, the
number of nickels, and ç, the number of
quarters that he has?
a) 25n +59 = 365
29-4=n
b) 5n +59 = 3.65
49 +2=n
c) 5n + 256 = 365
29-4=
d) 5n + 259 = 365
49-2=n
e) 25n +59 = 365
49-2=n
9514 1404 393
Answer:
c) 5n +25q = 365
2q -4 = n
Step-by-step explanation:
The number of nickels (n) is 4 less than twice the number of quarters (q), so one of the equations is ...
2q -4 = n
The face value is 365 cents, so another equation is ...
5n +25q = 365
These equations seem to match choice C.
How do you solve this system by elimination? 2x + 4y =8
Answer:
The answer is x=−2y+4
Step-by-step explanation:
1) Add -4y to both sides.
2x+4y+−4y=8+−4y
2x=−4y+8
Step 2: Divide both sides by 2.
2x/2=−4y+8/2
x=−2y+4
