What is the expression?
need to be done today!!
Answer:
[tex]\frac{1}{3}x + \frac{1}{2}[/tex]
Step-by-step explanation:
Rearranging the fractions:
[tex]\frac{1}{3} x+\frac{2}{3} x-\frac{2}{3} x +\frac{3}{4} -\frac{1}{4} \\\\= \frac{1}{3} x +\frac{2}{4} \\\\= \frac{1}{3} x + \frac{1}{2}[/tex]

Triangles E F D and A B C are shown. The length of side D F is 7. The length of hypotenuse A C is 7. Could these triangles be congruent? yes, if AB ≅ DE yes, if BC = 7 yes, if AB ≅ EF no, because the hypotenuses must have different lengths
Answer:
no, because the hypotenuses must have different lengths
Step-by-step explanation:
Yes, the given two triangles DEF and ABC are congruent, if AB ≅ DE.
Given that, EFD and ABC are two triangles.
What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Here,
If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.
From the triangles DEF and ABC,
∠F = ∠B (Equal angles measures 90°)
DF = AC (Equal in measure, which 7 cm)
To satisfy congruence, two sides and an angle have to be equal, if AB = DE then the two triangles would be congruent.
Yes, the given two triangles DEF and ABC are congruent, if AB ≅ DE.

Hey There!
If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50
So all we have to do is set up an equation
z+50=30+6x-45
step 1 combine like terms
30-45=-15
now we have
z+30=6x-15
step 2 add 15 to each side
-15+15 cancels out
30=15=45
now we have
z+45=6z
step 3 subtract z from each side
z-z cancels out
6z-z=5z
now we have
45=5z
step 4 divide each side by 5
5/5 cancels out
45/5=9
z=5
so we can conclude that z=9

Answer:
Sergio will buy the kayak first in 33.33 weeks.
Step-by-step explanation:
Sergio's per week savings = $24
Let the period of the savings = x
Then total savings of Sergio in x weeks = $24x
If y represents the total amount,
y = 24x ------(1)
Table given in the picture represents the savings of Lia.
If the points given in the table are plotted on graph, a straight line is formed.
Let the equation of the line is,
y = mx + b
m = Slope of line
b = y-intercept
Slope of the line = Savings per week
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
For two points (4, 72) and (8, 144) lying on the straight line,
Slope 'm' = [tex]\frac{144-72}{8-4}[/tex]
= [tex]\frac{72}{4}[/tex]
= 18
Equation of the line will be,
y = 18x + b
Since, (12, 216) also lies on the line,
216 = 18(12) + b
b = 216 - 216
b = 0
Therefore, equation of the line will be,
y = 18x -----(2)
Cost of kayak = $800
For Lia's savings,
800 = 18x
18x = 800
x = 44.44 weeks
For Sergio,
800 = 24x
x = 33.33 weeks
Therefore, Sergio will be able to buy the kayak first and it will take 33.33 weeks to purchase.
Over what interval is the function in this graph increasing?
Answer:
the function is increasing on (-4, 1)
Step-by-step explanation:
First the graph descends (drops), until it reaches x = -4. Then the graph rises, until x = 1. Thus, we say "the function is increasing on (-4, 1)."

Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?
O x= -1, x = 11
Ox=-1, x = -11
O x= 14 = -26
O x= 26, x=-14
Answer:
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2|x+6| - 4[/tex]
Required
Find x when
[tex]f(x) = 6[/tex]
Substitute 6 for f(x)
[tex]6 = 2|x+6| - 4[/tex]
Add 4 to both sides
[tex]4+6 = 2|x+6| - 4+4[/tex]
[tex]10 = 2|x+6|[/tex]
Divide both sides by 2
[tex]5 = |x + 6|[/tex]
Rewrite as:
[tex]|x + 6| = 5[/tex]
This can be split to:
[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]
Solve for x in both cases
[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]
[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Answer:
i think it’s x= -1, x = -11

14. Which special product is represented by: (5a? - 7b)??
a. Product of Two Binomials
c. Cube of a Binomial
b. Square of a Binomial
d. Product of a Binomial and a Trinomial
Answer:
[tex]A=2x^2+3x-5[/tex]
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
[tex]A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5[/tex]
So, the required area is equal to [tex]2x^2+3x-5[/tex].

70x + 25 = 50x +75
How many hours of service do the services cost the same?
Answer:
2.5 hours
Step-by-step explanation:
70x+25=50x+75
step 1 subtract 25 from each side
25-25 cancels out
75-25=50
Now we have
70x=50x+75
step 2 subtract 50 from each side
70x-50x=20x
50x-50x cancels out
now we have
20x=50
step 3 divide each side by 20
20/20 cancels out
50/20=5/2 or 2.5
so we can conclude that it will take 2.5 hours of service for the services to cost the same
