Answer:
See belowStep-by-step explanation:
The quadratic equation in factored form:
a(x - α)(x - β), where a- leading coefficient, α and β - rootsWe have:
a = 3, α = 1, β = -2Substitute them to get:
3(x - 1)(x + 2)Converting this into standard form:
3(x - 1)(x + 2) =3(x² + x - 2) =3x² + 3x - 62. Find two equivalent ratios of the following ratios: a) 27 : 9 b) 7 : 35
Answer:
see explanation
Step-by-step explanation:
Equivalent ratios are found by multiplying or dividing the parts of the ratio by the same value.
27 : 9 ( divide both parts by 9 )
= 3 : 1
(b)
7 : 35 ( divide both parts by 7 )
= 1 : 5
Is this triangle a right triangle? Explain.
Answer:
hmm
Step-by-step explanation:
I can't see any triangle there..a right angled triangle is meant to look like this
can anyone help me pls
Answer:
88 degrees, 44 degrees
Step-by-step explanation:
The total of angles in a triangle is 180 degrees
so, 48+x+x-44=180
48-44+x+x=180
4+2x=180
-4 on both sides
2x=176
x=88
Maya is using shapes to create a repeating pattern. Which rule will give Maya a repeating pattern that has a triangle as the 20th shape?
A.
triangle, square, circle, circle
B.
square, triangle, circle, circle
C.
square, circle, circle, triangle
D.
circle, circle, triangle, square
Answer:
B.
square, triangle, circle, circle
Step-by-step explanation:
Answer:
C. square, circle, circle, triangle
Step-by-step explanation:
The repeating patterns are 4 elements long. Element 20 will be the last element in the 5th repeat of the pattern. That is, the triangle must be the last element of the pattern.
The rule in choice C has the triangle last.

what number could make this equations have no value of x. 3x+8 = 3x + ?
Answer:
All values of x :- 3x + 8 = 3x + 8 has Infinite solutions .Just one value of X :- 3x + 8 = 3x + x is equal to 3x + 8 = 4x , which has one solution at x= 8 .Step-by-step explanation:
I hope this helps you !!if f(x)=4(3x-5), find f^-1(x)
Answer:
f^-1(x) = (x+20) / 12
Step-by-step explanation:
f(x) = 4(3x-5)
Let y be the image of f.
y = 4(3x-5)
y = 12x-20
y+20 = 12x
x = (y+20) / 12
f^-1(y) = (y+20) / 12, so
f^-1(x) = (x+20) / 12

how many solutions does the quadratic function f(x)=-x²
Answer: 4
Step-by-step explanation:
Slope = -2.000/2.000 = -1.000
x-intercept = 0/1 = 0.00000
f-intercept = 0/1 = 0.00000
x = 0
which of the following are equivalent
write the equation of the line with slope -3/2 passes through the point (-12,16)
Answer:
Step-by-step explanation:
You have two pieces if information: the slope of a line and a point on the line. So you can use the "point-slope" formula in order to write the equation of this line. It is a fill-in-the-blank type of formula.
y - y1 = m(x - x1)
In this fill-in-the-blank formula the y1, the m, and the x1 will be filled in with the numbers you were given.
The problem gave the slope as -3/2 , this is your m. On these linear equation problems and formulas, m always stands for the slope.
So fill that in:
y - y1 = -3/2 (x - x1)
They also gave you a point, that is the (x1, y1) that you need to fill in the formula. The point was (-12, 16), so -12 will be your x1 and 16 will be your y1. Fill it in!
y - 16 = -3/2 (x - -12)
Simplify that ugly 'minus a negative' in the parenthesis.
y - 16 = -3/2 (x + 12)
If you were never told what form of equation to write, or they said "any form of the equation", then you're done!
This is in "point-slope" form.
y - 16 = -3/2(x+12) Ta-da!
If you need to change it to "slope-intercept' form then there are a few more steps.
y - 16 = (-3/2)x + (-3/2)12
y - 16 = (-3/2)x - 18
+16 +16
y = -3x/2 - 2 This is y=mx+b (called slope-intercept form)
which ratio is equivalent to the ratio 7:6
Answer:
B. 21:18
Step-by-step explanation:
7/6 x 3 = 21/18
This means they are equivalent.
Answer:
Option B is correct.
Step-by-step explanation:
Let's first turn 7:6 into a fraction:
=> 7:6 = 7/6
Now, let's simplify all the options to see which one is the correct answer.
Option A:
=> 14:18=> 14/18=> 7/9=> 7/9 ≠ 7/6Therefore, Option A is incorrect.
Option B:
=> 21:18=> 21/18=> 7/6=> 7/6 = 7/6Therefore, Option B is correct.
Option C:
=> 21:12=> 21/12=> 7/4=> 7/4 ≠ 7/6Therefore, Option C is incorrect.
Option D:
=> 18:14=> 18/14=> 9/7=> 9/7 ≠ 7/6Therefore, Option D is incorrect.
We can conclude that Option B is correct.

What is the domain and range
Answer:
Step-by-step explanation:
Domain means what x's are on this graph, or what x's can you put into this equation. Range means what y's are in this graph or what y's can you get out if this equation. For y=x you can literally put in any x and get out any y, so the domain and range are both all real numbers. I couldn't see the choices on your drop down and there's several ways to write "all real numbers" as an answer. The absolute value graph y=|x| is a V-shaped graph so again, you can put in any x, but you only get positive numbers out (and 0, if you input 0) so the range us just all the y's that are 0 and bigger. That is y>=0. Again, there are several ways to write that such as {y | y>=0} or [0, infinity symbol)

Ai? (show equation).
Answer:
$39,227.50
Step-by-step explanation:
Vika's income will be ...
$35,500 + 10.5%×35,500 = $35,500(1 +0.105) = $39,227.50
Vika's adjusted income is $39,227.50.

Which THREE sets of angles can be used to construct triangles? A) 50°, 65°, 65° B) 45°, 50°, 85° C) 20°, 60°, 100° D) 30°, 60°, 70° E) 20°, 45°, 120°
Answer:
A) 50°, 65°, 65°
B) 45°, 50°, 85°
C) 20°, 60°, 100°
Step-by-step explanation:
To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).
A) 50° + 65° + 65° = 180° (Good!)
B) 45° + 50° + 85° = 180° (Good!)
C) 20° + 60° + 100° = 180° (Good!)
D) 30° + 60° + 70° = 160° (Bad!)
E) 20° + 45° + 120° = 185° (Bad!)

-3x + 4y = -15 and 4x - y = -19
Answer:
x=-7, y=-9. (-7, -9).
Step-by-step explanation:
-3x+4y=-15
4x-y=-19
---------------
y=4x-(-19)
y=4x+19
-3x+4(4x+19)=-15
-3x+16x+76=-15
13x=-15-76
13x=-91
x=-91/13
x=-7
4(-7)-y=-19
-28-y=-19
y=-28-(-19)
y=-28+19
y=-9

Please Help
Therefore, the answer is y = 67°.
Hoped this helped.
[tex]-BrainiacUser1357-[/tex]
Solution:
Note that:
Interior angles of a triangle sum up to 180°This means that...
56 + y + (180 - 123) = 180
Let's simplify the equation to find y.
=> 56 + y + (180 - 123) = 180
Simplify the LHS.
=> 56 + y + (57) = 180
=> 113 + y = 180
Subtract 113 both sides.
=> 113 - 113 + y = 180 - 113
=> y = 180 - 113 = 67°
