Answer:
The first equation of this system is y =2 x + 3.
The second equation of this system is y = 3x −1 .
The solution of the system is (4,11).
Step-by-step explanation:
PLATO CORRECT
The solution of the system of equations are (4, 11).
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
We have,
The first equation of this system is y = 2x + 3.
The second equation of this system is y = 3x - 1
Now,
y = 2x + 3 _____(1)
y = 3x - 1 _______(2)
(1) = (2)
2x + 3 = 3x - 1
3 + 1 = 3x - 2x
x = 4
Now,
Putting x = 4 in (1) or (2)
y = 2 x 4 + 3 = 8 + 3 = 11
y = 3 x 4 - 1 = 12 - 1 = 11
Thus,
The solutions of the system are (4, 11).

A. Express log 96 in terms of log 2 and log 3.
Answer:
linear equations
Step-by-step explanation:
Answer:
5log2 + log3
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
log[tex]x^{n}[/tex] ⇔ nlogx
Given
log96
Express 96 as a product of its prime factors
96 = [tex]2^{5}[/tex] × 3 , then
log96
= log([tex]2^{5}[/tex] × 3 )
= log[tex]2^{5}[/tex] + log3
= 5log2 + log3

Can you help me ? Pls
Answer:
The value of x = 4.4 units.
Step-by-step explanation:
Given that figure A is a scale image of Figure B.It is clear that the two sides are similar, so their corresponding angles will be congruent and corresponding sides are in proportion.
Thus, using the corresponding ratios of figure A and Figure B
[tex]\frac{x}{4}\:=\:\frac{11}{10}[/tex]
Multiply both sides by 10
[tex]\frac{x}{4}\cdot \:10=\frac{11}{10}\cdot \:10[/tex]
[tex]\frac{5x}{2}=11[/tex]
[tex]5x=22[/tex]
Divide both sides by 5
[tex]\frac{5x}{5}=\frac{22}{5}[/tex]
[tex]x=\frac{22}{5}[/tex]
[tex]x = 4.4[/tex]
Therefore, the value of x = 4.4 units.

En un curso hay 11 mujeres y 13 hombres. Si se eligen dos alumnos para representarlos en el campeonato de debate, ¿cuál es la probabilidad de que ambos sean hombres?
Answer:
106.34%
Step-by-step explanation:
hay 24 personas en total (11 mujeres+13 hombres)
la probabilidad para que uno de los alumnos es un hombre es 13/24 (porque hay 13 hombres en la clase)
Entonces, si uno hombre está elegido, quedan 12 hombres, así que, la probabilidad si es un hombre es 12/23 (porque una persona ya está elegido y quedan 23 personas)
la probabilidad es 13/24+12/23=587/552=106.34% (Redondeado a la décima más cercana)

What are the x and y intercepts for the equation / graph 3x - 2y = 6
Answer:
X= 2
y= -3
Step-by-step explanation
Answer:
Step-by-step explanation:
x intercept
The x intercept happens when y = 0
3x - 2y = 6
y = 0
3x = 6
x = 6/3
x = 2
x intercept = 2,0
The y intercept happens when x = 0
-2y = 6
y = 6/-2
y = -3
y intercept = 0,-3

Answer:
The equation for the function g is g(x) = [tex]\frac{12}{5}[/tex] x - [tex]\frac{29}{5}[/tex] ⇒ C
Step-by-step explanation:
The form of the equation of the linear function is g(x) = m x + b, where
m is the slope m is the y-interceptThe formula of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where (x1, y1) and (x2, y2) are 2 points on the line represents the function
From the given table
∵ The points (-3, -13) and (2, -1) belong to the function g(x)
∴ x1 = -3 and y1 = -13
∴ x2 = 2 and y2 = -1
→ Substitute them in the formula above to find m
∵ m = [tex]\frac{-1--13}{2--3}[/tex] = [tex]\frac{-1+13}{2+3}[/tex] = [tex]\frac{12}{5}[/tex]
∴ m = [tex]\frac{12}{5}[/tex]
→ Substitute in the form of the equation above
∴ g(x) = [tex]\frac{12}{5}[/tex] x + b
∵ There is only one choice that has m = [tex]\frac{12}{5}[/tex]
∴ The equation for the function g is g(x) = [tex]\frac{12}{5}[/tex] x - [tex]\frac{29}{5}[/tex]
∴ Choice C represents the equation of function g
Which property can be used to solve the equation?
5d=75
addition property of equality
subtraction property of equality
O multiplication property of equality
O division property of equality
Step-by-step explanation:
It is multiplication property of equality. The goal is to get d by itself so what we do here is basically a process of
[tex]5d=75\\\\5d/5=75/5\\\\d=15[/tex]
Answer:
Division property of equality...
Step-by-step explanation:
The person above me was close, and they were right about the process of getting 15, but it is not multiplication property of equality.
Proof:
1. You have to undo what has been done to find out d, the variable that we are solving for. In other words, we're simply solving for x.
2. You can't undo the multiplication by doing more multiplication.
3. Given: 5d=75, and by doing inverse operations, you flip it around to:
75 ÷ 5 = d. this is the division property of equality because we're doing the opposite of multiplication to solve for d, and we're undoing the multiplication.
4. Do the math, or use a calculator to find what 75 divided by 5 is.
5. The answer is 15, so 15 = d.
Therefore,
It is "D," division property of equality.
