Find the sum and product of zeroes of the quadratic polynomial 2x2-7x+5 and verify the
results.
• 2x²-7x +5 =0
=> 2x²-5x-2x+5 = 0
=> x ( 2x-5)-1(2x-5)=0
=> (x-1)(2x-5) = 0
• x-1=0
=> x= 1
• 2x-5=0
=> x = 5/2.
Now , Verification :
Here , a= 2 ,b= -7 and c = 5
As we know that :
• Sum of zeroes = -b/a
• 5/2+1 = -(-7)/2
• 7/2 = 7/2
LHS = RHS.
• Product of zeroes = c/a
=> 1(5/2)= 5/2
=> 5/2 = 5/2.
LHS = RHS ..
Hence, verified .
I hope it will help you.

Answer:
120°
Step-by-step explanation:
3x-105+2x+10=180
collect like terms
5x-95=180
5x=275
x=55
angle 8 is equal to angle 6 because vertically opposite angles are equal
angle 6 =(2x+10) = 120
therefore angle 8 =120 degrees

What's the equation of a line that passes through (3, 4) and (0, -2)
Show work pleaseeee
Jack works after school. Each day he is paid a set amount, plus an hourly wage.
Hours 1 1.5 2 2.5 3
Pay 18 23 28 33 38
Which is a reasonable domain for the function f(x) = 10x + 8?
A. 0 < x < 6
B. 0 < x < 24
C. 0 < x < 68
D. 0 < x < 248
Answer:
The correct option is;
A. 0 < x < 6
Step-by-step explanation:
The given data indicates how much Jack is paid on hourly wage is presented here as follows;
Hours [tex]{}[/tex] Pay
1 [tex]{}[/tex] 18
1.5 [tex]{}[/tex] 23
2 [tex]{}[/tex] 28
2.5 [tex]{}[/tex] 33
3 [tex]{}[/tex] 38
Given that the domain is the number of hours worked by Jack after school, and that he receives a set amount at all values of the number of hours worked, a reasonable domain is from 0, at which the pay is 8, to 6 which is less than the normal 8 hours a day job, as he works part time.
Therefore, the correct option is;
A. 0 < x < 6.
Write the equation in slope-intercept form of a line that passes through the point (-6, -12) and is perpendicular to y=-2x+5.y=−2x+5.
Answer:
Step-by-step explanation:
The standard form of equation of a line in slope-intercept form is expressed as:
y =mx+c
m is the slopw
c is intercept
Get the slope of the known line
since y = -2x+5
slope m = -2
Get the slope of unknown line
Since the unknown line is perpendicular to tis line, then
Mm = -1
M = -1/m
M = -1/-2
m = 1/2
Get the intercept of the unknown line:
Substitute the point (-6,12) and m = 1/2 into the equation y = mx+c
12 = 1/2(-6) + c
-12 = -3 + c
c = -12+3
c = -9
Get the equation of the unknown line:
Substitute m = 1/2 and c = -9 into the equation y = mx+c
y = 1/2x -9
2y = x - 18
2y-x = -18
Hence the equation in slope-intercept form of a line that passes through the point (-6, -12) and is perpendicular to y=-2x+5 is 2y-x = 18

Translate the point D(2, -4) 7 units to the left and 2 units down. What are the coordinates of the new point? Write your answer as an ordered pair (x, y). *
Answer:
(-5, -6)
Step-by-step explanation:
Solve this by doing x- and y- separately.
For the x-axis:
Let right be the positive direction, so x = 2 -7
x = -5
For the y-axis:
Let up be the positive direction, so x = -4 -2
x = -6

What is the slope of the line that runs through the two points?
(-20,-4) (-12, -10)
Answer:
Slope = -6/8
Step-by-step explanation:
(-20, -4)
(-12, -10)
Slope = (Y2 - Y1)/(X2 - X1)
Plug in the x and Y coordinates:
-10 - (-4)/-12 - (-20)
-10 + 4/-12 + 20
-6/8
Slope = -6/8

Can somebody Help ? Me please .
Answer:
B
Step-by-step explanation:
The Associative Property means no matter where the parenthesis are placed, the numbers and the answer is still the same. For example: 5+(7+8) is the same as (5+7)+8 because it has the same answer and the result isn't changed from where the parenthesis are. :) Hope this helps!
~Happy Halloween!~
Answer: B
Step-by-step explanation:
According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped, and B no matter how the numbers are grouped it'll give the same answer.

[tex]\sqrt8a-5-\sqrt6a+8=0[/tex]
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
You would start by writing it out again then simplifying.
[tex]\sqrt{8}a-5-\sqrt{6}a+8=0\\.378937a+3=0[/tex]
Now let's subtract 3 from both sides...
[tex].378937a=-3[/tex]
Now we'll divide the sides by .378937....
[tex]a=-7.916883[/tex]
So a equals -7.916883
Ms. Lee went and got a haircut for $35.00, and the tax was 7%. She also left a 30% gratuity for the hairdresser.
3a. What was the total amount Ms. Lee spent for the haircut?
Answer:
$48.685 or $48.69
Step-by-step explanation:
Bill = 35 * 1.07 = 37.45
Tip: 37.45 * .30 = 11.235
Total: 37.45 + 11.235 = $48.685 or $48.69

The supplementary angle of 77° is
Answer:
103°
Step-by-step explanation:
A supplementary angle is when two angles add up to be 180°. So, we can subtract to find its suplement.
180 - 77 = 103

Isabelle has a five-sided chicken coop in her yard. Each side has an equal length. What is the total perimeter of the chicken coop if the length of one side is yards? Recall that the perimeter is the sum of all sides of a shape or boundary.
Answer:
P = 175 yards
Step-by-step explanation:
Isabelle has a five-sided chicken coop in her yard. The length of each side is equal.
Let the length of one side is 35 yards.
We need to find the total perimeter of the chicken coop.
Perimeter = sum of all sides of a shape or boundary
P = 35+35+35+35+35
P = 5(35)
P = 175 yards
So, the perimeter of the chicken coop is 175 yards.

For a sewing project, Tanya cut isosceles triangles from a striped piece of material where the stripes are parallel. The vertex angle of the isosceles triangle is 50° and overline BC is parallel to the base.
What is the measure of BCE as shown in the diagram? Show your work and
explain your reasoning.
Answer:
∠BCE is 115°
Step-by-step explanation:
The given parameters are;
The shape Tanya cut from the striped piece = Isosceles triangles
The measure of the vertex angle of the isosceles triangle = 50°
The segment [tex]\overline {BC}[/tex] is parallel to the base [tex]\overline {FG}[/tex]
Therefore, we have;
∠GAF + ∠AGF + ∠AFG = 180°; Sum of the interior angles of a triangle
∴ ∠AGF + ∠AFG = 180° - ∠GAF = 180° - 50° = 130°
∠AGF = ∠AFG; Base angles of an isosceles triangle
∴ ∠AGF + ∠AFG = ∠AGF + ∠AGF = 2 × ∠AGF = 130°
∠AGF = 130°/2 = 65°
∠AGF = 65°
∠AGF ≅ ∠ACB, corresponding angles of two parallel lines, [tex]\overline {BC}[/tex] and [tex]\overline {FG}[/tex] cut by a transversal [tex]\overline {AG}[/tex]
∠AGF = ∠ACB = 65°, definition of congruency
∠ACB + ∠BCE = 180° Sum of angles on a (straight) line
∠BCE = 180° - ∠ACB = 180° - 65° = 115°
∠BCE = 115°
