If two lines in a linear system __________, they have exactly one point in common.

Answer:

x= -5

x= 9

Step-by-step explanation:

Answer:

x = - 5, x = 9

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

(x + 5)(x - 9) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 9 = 0 ⇒ x = 9

The square root of 1/64 is 1/8.

To find the square root of 1/64, we can simplify the fraction first by taking the square root of both the numerator and the denominator separately.

The square root of 1 is 1,

and the square root of 64 is 8:

So, √(1/64)

= √1 / √64

= 1/8

Therefore, the square root of 1/64 is 1/8.

Step-by-step explanation:

Answer:

13x

Step-by-step explanation:

you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x

=====================================================

Explanation:

x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.

Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.

This is one way to see how 8x+5x = 13x

Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.

Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.

Answer:

You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.

Answer: C

Step-by-step explanation:

Answer:

the answer is C I swear to yo mama

Turn both equations into slope-intercept form [ y = mx + b ].

x + 3y = 3

~Subtract x to both sides

3y = 3 - x

~Divide 3 to everything

y = 1 - x/3

~Reorder

y = -1/3x + 1

4x + 3y = -6

~Subtract 4x to both sides

3y = -6 - 4x

~Divide 3 to everything

y = -2 - 4x/3

~Reorder

y = -4/3x - 2

Graph of the equations will be shown below. Note that the solution of graphing two equations will be where both equations intersect. Both lines intersect at (-3, 2), hence making that the solution.

Hey, so this is what I got for them as equations. The 1st one is y=-1/3x+1, and the 2nd one is y=-4/3x-2.  Hope it helps

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

You need to find the slope in A.  y = x + (4x - 1) = 5x -1.   The slope is 5.

In B,  as x increases 1 unit, y increases 1 unit.  Therefore, the rate of change is 1/1 = 1

Conclusion:  In A the rate of change is 5 and in B the rate of change is 1.

Therefore, A has a greater rate of change

Answer: To factor a trinomial in the form x2 + bx + c, find two integers, r and s, whose product is c and whose sum is b. Rewrite the trinomial as x2 + rx + sx + c and then use grouping and the distributive property to factor the polynomial. The resulting factors will be (x + r) and (x + s).

Step-by-step explanation:

Step-by-step explanation:

We have y = 13 - 3x and y = 7 - x.

=> 13 - 3x = 7 - x

=> 2x = 6, x = 3.

Then y = 7 - (3), y = 4.

Step-by-step explanation:

What

Answer:

23/5

is the 4.6 fraction

The decimal 4.6 is equivalent to the fraction 23/5.

The whole number part of the decimal, which is 4, will be the numerator of the fraction.

The decimal part, which is 0.6, will be the numerator of the fraction divided by the appropriate power of 10.

In this case, the decimal has one digit after the decimal point, so we divide it by 10¹.

0.6 / (10¹)

= 0.6 / 10 = 6/10

Simplify the fraction if possible.

Both the numerator and denominator can be divided by their greatest common divisor, which is 2 in this case.

6/10 = (6/2) / (10/2) = 3/5

Therefore, the decimal 4.6 is equivalent to the fraction 4 3/5 or simply 23/5 after simplification.
