Solve systems using Elimination
Answer:
y = 1.5, x = [tex]1\frac{12}{13}[/tex]
Step-by-step explanation:
The given simultaneous equation system is;
-1 - 2·y = -4...(1)
13·x + 2·y = 28...(2)
By elimination method, we have;
From equation (1);
-1 - 2·y = -4
2·y = 4 - 1 = 3
y = 3/2 = 1.5
y = 1.5
We eliminate 'y' from equation (2) by replacing the value of 'y' with 1.5 as follows;
13·x + 2·y = 28
y = 1.5
∴ 13·x + 2 × 1.5 = 28
13·x = 28 - 3 = 25
x = 25/13 = [tex]1\frac{12}{13}[/tex] = [tex]1.\overline{923076}[/tex]
x = [tex]1\frac{12}{13}[/tex]

12m - 4 + 5m
12m + 5m = 17m
17m - 4
Answer:
7m-4
Step-by-step explanation:
12m - 4 - 5m (Distribute the negative)
7m - 4 (Subtract the m values and you got the answer)
Perform the indicated operation and state the domain. Let f(x) = 3x^1/3 and g(x) = 2x^1/2 Express as (f+g)(x)
Answer:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
[tex]x \ge 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^{\frac{1}{3}}[/tex]
[tex]g(x) = 2x^{\frac{1}{2}}[/tex]
Solving (a): (f + g)(x)
In functions:
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
Solving (b): The domain of f(x)
For (f + g)(x) to be defines, the value of x must be greater than or equal to 0.
Hence, the domain is:
[tex]x \ge 0[/tex]

Find the length of BC
Answer:
BC = 15
Step-by-step explanation:
Because the triangles ACD and BCE are similar, we can infer that
AC/DC = BC/EC
and subsequently
AB/DE = BC/EC
3/2 = BC/10
BC = 10*3/2 = 15

Answer:
[tex]\frac{x+4}{x+1}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x^2-16}{x^2-3x-4}[/tex] ← factor numerator/ denominator
= [tex]\frac{(x-4)(x+4)}{(x-4)(x+1)}[/tex] ← cancel the factor (x - 4) on numerator/ denominator
= [tex]\frac{x+4}{x+1}[/tex]

Find the length of a side of a square if its area is:
0.49 square units
Answer:
Side = 0.7 units
Step-by-step explanation:
Area of a square = 0.49 sq. units
Side² = 0.49
side² = [tex]\frac{49}{100}\\\\[/tex]
[tex]side = \sqrt{\frac{49}{100}}=\sqrt{\frac{7*7}{10*10}}\\\\sides=\frac{7}{10}=0.7[/tex]

Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (16, 17) and (x₂, y₂ ) = (15, 16)
m = [tex]\frac{16-17}{15-16}[/tex] = [tex]\frac{-1}{-1}[/tex] = 1

pasagot po tnx
I will mark you as brainliest if your answer is good :3
Answer:
416.50 pesos
Step-by-step explanation:
Given
Represent the bread with b.
Mayonnaise with m
Ham with h
[tex]Amount\ Paid = 1000[/tex]
Required
Determine the change
From the question: a loaf costs 22.50
This is represented as:
[tex]b = 22.50[/tex]
5 loaves will be:
[tex]5*b = 22.50*5[/tex]
[tex]5b = 112.50[/tex]
A bottle of Mayonnaise costs 55.50
This is represented as:
[tex]m = 55.50[/tex]
2 bottles will be:
[tex]2*m = 55.50*2[/tex]
[tex]2m = 111[/tex]
Lastly,
1kg of ham costs 240
This is represented as:
[tex]h =240[/tex]
1.5kg will be:
[tex]1.5*h =240*1.5[/tex]
[tex]1.5h =360[/tex]
The cost of the items is:
[tex]Costs = 5b + 2m + 1.5h[/tex]
This gives:
[tex]Costs = 112.50 + 111 + 360[/tex]
[tex]Costs =583.50[/tex]
Her change is calculated as:
[tex]Change = Amount\ Paid- Cost[/tex]
[tex]Change = 1000 - 583.50[/tex]
[tex]Change = 416.50[/tex]
