4x-5y=12, 6x+10y=18: solve by addition method
Answer:
x = 3 , y= 0
Step-by-step explanation:
Answer:
[tex]x=3[/tex];[tex]y=0[/tex]
Step-by-step explanation:
Double the first one, and add it to the second, to get rid of y
[tex]2I + II :8x -10y +6x -10y = 24+18\\14x = 42 \rightarrow x=3\\[/tex]
For the second value, let's take 3 times the first, subtract twice the second, and solve:
[tex]3I-2II: 12x-15y-(12x+20y)=36-36\\-15y-20y=0 \rightarrow -45y=0 \rightarrow y=0[/tex]
Use the discriminant formula to find the number of x-intercepts in the graph of the equation.
x2 – 3x + 2 =y
b2 - 4ac
Answer:
2
Step-by-step explanation:
The values of a, b, c are ...
a = 1, b = -3, c = 2
Then the discriminant is ...
d = b^2 -4ac
d = (-3)^2 -4(1)(2) = 9 -8 = 1
The discriminant is positive, so there are two x-intercepts.
_____
Additional comment
The indications given by the discriminant are ...
d > 0, 2 real roots (2 x-intercepts)
d = 0, 1 real root (1 x-intercept)
d < 0, 2 complex roots (0 x-intercepts)

Find 6 / 2(9) . Express your answer as a fraction in simplest form.
Answer:
3 or 3/1
Step-by-step explanation.
since 9 is in parenthuses, do 2x9, then you have the fraction 6/18, and 6 does into 18 3 times evenly, so the answer is 3.
The simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The fraction is:
= 6/2(9)
From the definition of the fraction, the top of the fraction number is called the numerator and the second is the bottom of the fraction number which is called the denominator.
In the given fraction the number 6 is in the numerator and 2(9) is in the denominator.
= 6/18 (after the multiplication of 2 and 9)
= 1/3 (divide by 6 on the numerator and denominator)
Thus, the simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.

4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)
9514 1404 393
Answer:
f(x) = 4·3^x
Step-by-step explanation:
We assume the function will be of the form ...
f(x) = a·b^x
Substituting the given values, we can find 'a' and 'b'.
4/9 = a·b^(-2)
108 = a·b^3
Dividing the second equation by the first gives ...
108/(4/9) = b^(3 -(-2))
243 = b^5
b = 3 . . . . . . 5th root
Using the second equation, we can find 'a':
108 = a·3^3 = 27a
a = 108/27 = 4
The formula for the exponential function is ...
f(x) = 4·3^x

What value of x makes the equation true?
Answer:
x = 9/4
Step-by-step explanation:
-3x + 10 = 5x - 8
Add 3x to both sides
10 = 8x - 8
Add 8 to both sides
18 = 8x
Divide both sides by 8
18/8 = x
Reduce
9/4 = x
x = 9/4
Sean runs a marathon, which is 26.2 miles long. A mile is about 1.61 kilometers. What is the distance to the nearest kilometer?
26.2miles:-
[tex]\\ \sf\longmapsto 26.2(1.61)[/tex]
[tex]\\ \sf\longmapsto 42.182[/tex]
[tex]\\ \sf\longmapsto 42km[/tex]
The given distance to the nearest kilometer is 42 kilometers.
Given that, Sean runs a marathon, which is 26.2 miles long.
Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
We know that, a mile is about 1.61 kilometers.
Here, number of kilometers = 26.2×1.61
= 42.182 kilometers
≈ 42 kilometers
Therefore, the given distance to the nearest kilometer is 42 kilometers.

3x - 1 can be written in a verbal form as "1 less than the product of 3 and a number x
Functions can be translated using words in mathematics
Given the function 3x - 1
Let x be the unknown number
3x is translated as the product of 3 and a number.
Since 1 is subtracted from the function this means that the function 3x is lesser by a value of 1.
