Answer:
y = -2x + 1
Step-by-step explanation:
The equation is in standard form, first, we need to convert it to slope-intercept form.
5 = -10x - 5y
5 + 10x = -5y
Divide both sides by -5 to isolate y variable.
y = -2x - 1
If the line is parallel, the slope remains the same.
To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b
5 = -2(-2) + b
5 = 4 + b
1 = b
The equation is -2x + 1
If f(x)=3x^2 +x-2, then f(-2)=

The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.
Answer:
103Step-by-step explanation:
Given function:
y = -x² + bx + 3The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = -b/2aThe given function has:
x = 10, and a = -1Find the value of b:
10 = -b / -2b = 20The function is:
y = -x² + 20x + 3The y-coordinate of the vertex is:
y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103Answer:
Solution given:
y = -x² + bx + 3
we have
The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = [tex] \frac{ - b}{2a} [/tex]
we have
x = 10, and a = -1
Substituting value of a in -b/2a
we get
b = 20
now
The y-coordinate of the vertex is:
y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

What is the volume of this pyramid?
Answer:
150 cm
Step-by-step explanation:
It's 150 cm because if you multiply L x W x H, you will get your answer. So it would be 6 x 5 x 5 = 150.

-x + 3y = -12 in slope intercept form. please show step by step. thanks :)
Answer:
y=x/3 - 4
Step-by-step explanation:
add x to get x to the other side
3y= x-12
divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form
Answer:
slope intercept form is y=mx+b
add x to both sides : 3y=x-12
divide by 3 on both sides : y=(1/3)x-4

What is the median? 0.8 1.0 2.7 2.8 3.1 13.3
Answer:
2.75
Step-by-step explanation:
The median is just the middle number in the number set. So, you put the numbers in order (which they already are), and find the middle number. If there are two numbers in the middle (which only happens if there is an even amount of numbers), then you add both of them and divide by 2 (which we must do in this problem).
0.8, 1.0, 2.7, 2.8, 3.1, 13.3
(2.7 + 2.8)/2
(5.5)/2 = 2.75
So, the median is 2.75.
Hopefully this helped, good luck!
Step-by-step explanation:
Arranging the numbers in an ascending order:
0.8 1.0 2.7 2.8 3.1 13.3
Median = (3rd value + 4th value) / 2
[tex] = \frac{2.7 + 2.8}{2} \\ = \frac{5.5}{2} \\ = 2.75[/tex]

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?
Answer:
$64.89
Step-by-step explanation:
57.68 + 1.25 × 57.68
= 57.68 + 72.1
= 129.78
The original price was $129.78.
129.78 – 0.50 × 129.78
= 129.78 – 64.89
= 64.89
The discount price was $64.89.
Answer:
$64.89
Step-by-step explanation:
The roots of the equation x² + 2x + 4 = 0 are
A) rational and equal
B) rational and unequal
C) imaginary and unequal
D) real, rational, and unequal
Answer:
Option C
Step-by-step explanation:
Given :-
A equation x² + 2x + 4 = 0 .And we need to find out the nature of the roots . The nature of the roots is determined by the Discriminant of the equation , and the Discriminant of a quadratic equation is ,
[tex]:\implies[/tex] Discriminant = b² - 4ac
[tex]:\implies[/tex] Discriminant = 2² - 4(1)(4)
[tex]:\implies[/tex] Discriminant = 4 -16
[tex]:\implies[/tex] Discriminant = (-12)
Now here the value of D is less than 0 .So the roots will be imaginary .
Hence the roots are imaginary and unequal.
Ronique recorded the number of games that the school softball team won each year for the past 7 years: 31, 24, 32, 22, 34, 28, 38. Ronique's team won at least (blank)
games in 75% of the seasons that they played.
Answer:
Ronique's team won at least 24 games in 75% of the season that they played.
Step-by-step explanation:
(The box-whisker plot below will show everything, but I'll explain it in detail because I want to be more helpful)
So... we have seven data points.
2014 - 15 (Year 1): 31 wins
2015 - 16 (Year 2): 24 wins
2016 - 17 (Year 3): 32 wins
2017 - 18 (Year 4): 22 wins
2018 - 19 (Year 5): 34 wins
2019 - 20 (Year 6): 28 wins
2020 - 21 (Year 7): 38 wins
We need a box & whisker plot for this.
22 will go on the left whisker, since it's the lowest of the data points. 38 will go on the right whisker, since it's the highest.
For the two quartiles, 24 is the first quartile, so from that point to the right whisker, that's 75% of the data. The third quartile will be 34. And the midline will be at 31, since it's the median of the data points.
From that explanation, we can be sure that Ronique's team won at least 24 games in 75% of the seasons that they played.

Answer:
x ≈ 47°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{11}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{8}{11}[/tex] ) ≈ 47° ( to the nearest degree )
