The leading coefficient would be 5

Answer:The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.

So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.

Why? because it stands in front of the variable.

Which function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across t

irina1246 [14]

Answer:

g(x)=-8(3^x)

Step-by-step explanation:

Given: f(x)=3^x

Multiply by 8: f(x)=8(3^x)

Negate function: g(x)=-8(3^x)

Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be

zalisa [80]

The absolute value of a number $x$ is the positive version of that number. So, if $x$ is positive, its absolute value is $x$ itself. If $x$ is negative, its absolute value is $-x$ , so that it will be positive again.

So, if the absolute value of a number is smaller than a certain quantity, i.e. $|x|$ it means that the positive version of $x$ is less than $a$ .

So, if $x$ is positive, the inequality becomes $x$ . If $x$ is negative, the inequality becomes $-x-a$ .

So, as a compound inequality, we have

$|x|$

So, in your case, we have

$|x-8|$

Add 8 to all sides in this inequality:

$8-0.01 < x < 8+0.01 \iff 7.79 < x$

So, on a number line, you must higlight all numbers between 7.79 and 8.01, endpoints excluded.

Conceptually, this means that the bolt measurement should be exactly 8mm, but you can accept bolts that are 0.01 millimeters shorter of larger.

Y=x-7<br> 6x-6y=-7<br><br> elimination method

Archy [21]

Answer:

The system has no solutions.

Step-by-step explanation:

Let's write it in a more traditional form

$\left \{ {{x-y=7} \atop {6x-6y=-7}} \right. \\$

Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.

Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
