Can someone help me with 9 and 10 please

It would cross the y-axis at 2 and it would cross the x-axis at -2

Explanation- x is the horizontal line and the y is the vertical line. Basically whichever number the line crosses on the x-axis line or the y-axis line would be your answer.

Hope this helps(:

Place the following linear equation in slope intercept form: 6x - 4y = 9
geniusboy [140]

Answer:

y = 3/2 x - 9/4

Step-by-step explanation:

bring all the y's to one side.

4y = 6x-9

divide by 4 to isolate the y

y = 6/4x - 9/4

simplify

y = 3/2 x - 9/4

If c(x)=5/x-2 and d(x)=x+3 what is the domain of (cd)(x)?. . And, if f(x)=7+4x and g(x)=1/2x, what is the value of (f/g)(5)?
Vesna [10]
1. The value of (cd)(x) is equal to the product of c(x) and d(x) which is equal to,
                                         5(x + 3) / (x - 2)
The function can take all real numbers except 2 because that would make the denominator 0. 

2. To answer, substitute first 5 to the given functions,
                      f(x) = 7 + 4x = 7 + 4(5) = 27
                      g(x) = 1/2x = 1 / (2)(5) = 1/10
Dividing 27 by 1/10 is 270.

A system of equations has no solution. if y = 8x 7 is one of the equations, which could be the other equation? 2y = 16x 14 y = 8
SCORPION-xisa [38]

A system of equations has no solution. if y = 8x+ 7 is one of the equations, The other equation will be y = 8x - 7.

<h3 /><h3>What is the system of two equations?</h3>

A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.

The first equation is given as:

y = 8x + 7

The equations in the system would have different constant values if the system of equations had no solution.

y=8x+b

Where:

b is a variable that is not equal to 7.

The equation whose standard form is y=ax+b has no solution. Only equation 2 satisfies the generalized form.

Hence.if y = 8x+ 7 is one of the equations, The other equation will be y = 8x - 7.

To learn more about the system of two equations refer to the link;
