Find the intersection points of the parabola y=−3x2−2x+2 and the line 10x−y=−11. Give your answer as two ordered pairs separated by a comma. For example, if you found that the solutions were (1,2) and (3,4) you would enter (1,2),(3,4).
Answer:
(-1,1),(-3,-19)
Step-by-step explanation:
y=−3x²−2x+2 (1)
10x−y=−11
y=10x+11 (2)
−3x²−2x+2 = 10x+11
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
(x + 1)(x+3) = 0
x= -1 or x = -3
y = 1 or y = -19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
y = −3x² − 2x + 2 ...1
10x − y = −11 ...2
From equations 1 and 2, then we have
10x + 11 = −3x² − 2x + 2
3x² + 12x + 9 = 0
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x(x + 3) + 1(x + 3) = 0
(x + 3)(x + 1) = 0
x = -1, -3
The value of y at x = - 1 is given as,
y = 10(-1) + 11
y = 1
The value of y at x = -3 is given as,
y = 10(-3) + 11
y = - 19
The solutions of the equations y = −3x² − 2x + 2 and 10x − y = −11 will be (-1, 1) and (-3, -19).

Henry worked for 8 days, Jack worked for 9.5 days while Steffi worked for 6.5 days to complete a project. If the amount earned for the project completion was shared among them in the ratio of the number of days each one had worked, find the ratio in which the amount was shared.
Answer:
The ratio in which the amount is shared is 16:19:13
Step-by-step explanation:
The given parameters are;
The number of days Henry worked = 8 days
The number of days Jack worked = 9.5 days
The number of days Steffi worked = 6.5 days
The sharing formula for the amount earned for the project = The ratio of the number of days worked by each one
The total number of days worked by all three = 8 days + 9.5 days + 6.5 days = 24 days
The fraction of the total number of days Henry worked = (8 days)/(24 days) = 1/3 = 16/48
The fraction of the total number of days Jack worked = (9.5 days)/(24 days) = 19/48
The fraction of the total number of days Steffi worked = (6.5 days)/(24 days) = 13/48
Therefore. the ratio in which the amount is shared = 16:19:13 (which is the same as the ratio of the number of days worked)

Simon had $15 to spend for lunch. He bought a large orange soda for $3.25 and a
cheeseburger for $11.95. When he reached in his pocket to pay, he found another
$4.25 to use towards his bill. How much money did Simon have after paying for
lunch?
Answer:
$4.05
How:
1. $15 + the extra $4.25 = $19.25
2. $3.25 + $11.95 for the meal = $15.20
3. $19.25 - $15.20 = $4.05
Simon had $4.05 left after paying for lunch.

Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just

Find the leg of an isosceles right triangle when the hypotenuse measures 8
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
ratio of leg to hypotenuse in a 45-45-90° triangle is 1 : [tex]\sqrt{2}[/tex]
we can use this proportion to solve the problem:
let 'x' = leg
x/8 = 1/[tex]\sqrt{2}[/tex]
cross-multiply:
[tex]\sqrt{2}[/tex] x = 8
x = 8 / [tex]\sqrt{2}[/tex]
if you multiply top and bottom by [tex]\sqrt{2}[/tex] you will get 4[tex]\sqrt{2}[/tex]

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Parallel lines.
To make them parallel ,just equate them.
5x = 3x + 60
===> 5x - 3x = 60
===> 2x = 60
.hence, x = 30
====> x = 30
The value of x for which A || B is 15° as they are pair of alternate angles.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
Given, are two alternate angles 5x and 3x + 60, the lines A and B will be parallel if the sum of these two angles is 180°.
∴ 5x + 3x + 60 = 180°.
8x = 120°.
x = 120/8.
x = 15.

what formula would you use to find the area of this figure?
Step-by-step explanation:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units. Calculate the area of a four-sided shape that is not a rectangle by multiplying the base (one of the sides) by the height.

Answer:
119
Step-by-step explanation:
151 is the outside of the angle so you do 180-151 which is 29 and that plus 32 which is 61 and then 180-61 which is 119
Answer:
x = 119°
Step-by-step explanation:
180° - 151° = 29°
so now we have two angles: 29° and 32°.
32° + 29° + x = 180°
61° + x = 180°
x = 119°
