Answer:

  x = -6

Step-by-step explanation:

The zero is where the graph crosses the line y=0 (the x-axis). It is also called the x-intercept.

That point is (-6, 0). The x-value there is -6.

__

Some folks like the x-value only; others like the ordered pair. Of course the y-value in the ordered pair is 0, which is what makes it a zero of the function.

Answer:

Question 1.  38.6 %   2.  61.4%

Step-by-step explanation:

(New Cost - Old Cost) ÷ old Cost × 100

    (305 - 220) ÷ 220 x 100

    =   85/220 x 100

    = 38.6 %

2.  New Cost 305 + 50 = $355    

(Now new cost - old cost) ÷ old cost ×  100

    (355 - 220)  ÷ 220 × 100  

    =  135/220 × 100

        61.4%

Answer:

  y = -2x +2

Step-by-step explanation:

The slope is the y-change divided by the x-change:

  m = (y2 -y1)/(x2 -x1)

  m = (0 -2)/(1 -0) = -2

The y-intercept is the y-value when x=0: b = 2.

The slope-intercept equation is ...

  y = mx +b

  y = -2x +2

Answer:

See below:

Step-by-step explanation:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.

We can solve the problem in 2 steps, one being Solving and the other being Comprehending. I'll start off with comprehending.

Comprehending

So, we know that 10% of a number is $16. That means that [tex]\frac{1}{10}[/tex] of the number "[tex]x[/tex]" is equal to $16.

A percentage is basically a fraction of something, for example, 25% of a number would be [tex]\frac{1}{4}[/tex] of the same number.

Example:

25% of 10 = [tex]\frac{1}{4} * 10 = 2.5[/tex]

2.5 is 25% of 10 = [tex]2.5 \div \frac{1}{4}=10[/tex]

Now that we know the basics, we can do the real solving.

Solving

To solve, the question, we can first read the problem and make an equation,

"10% of [tex]x[/tex] is 16."

We can then make a equation.

[tex]x(\frac{1}{10})=16[/tex]

[tex]x=16 \div \frac{1}{10} \\x=160[/tex]

After solving, we know that 10% of 160 is equal to 16. We can prove that with the following:

[tex]16*10=160[/tex]

After solving our equation, we can see that the answer is $160.

$16 is 10% of $160.

Cheers!

Answer:

Step-by-step explanation:

Given trinomial:

It has two perfect squares  and a variable with negative coefficient.

It can be representing a:

If we substitute m with x and n with 4,  we'll get 2mn = 2*x*4 = 8x.

This gives us b = 8

Answer:

Answer:

y=-9x-1

Step-by-step explanation:

since it is perpendicular, the slope must be the opposite reciprocal (-9x) and now we plug the coordinates in, -1=0+b, b is -1

Answer:

y=-9x-1

Step-by-step explanation:

Answer:

Slope = 3/1

Step-by-step explanation:

Slope equals y/x

For every 2 units of increase for the x value, there is an increase of 6 in y value

y/x = 6/2

6/2 = 3/1

Answer:

Total Area = 235cm^2

Step-by-step explanation:

Step 1 ) we have our lengths 11 and 20 so we need to separate the into 2 shapes  Step 2)   Label and draw new shape 20-11 = 9  to show (Shape square  1) = measuring 9 *9 and   another  (Shape Rectangle 2) = 11* 14  Step 3) Show how you do the multiplication of Square shape 9* 9 = 81cm^2  and Area Rectangle 11 * 14 = 154 cm^2   Total Area = 81+154 = 235cm^2    You can if you like in table multiplication show 11*14 by adding a zero underneath the 14 = 140 +14 = 154 then add and show +81 = 235cm^2 It is always easier to retain a shape if subtracting to get a 2nd shape this way it saves time with subtraction and in my example only needed to subtract 20-11 = 9 then 9*9 = 81cm^2 to retain the 14 *11 = 154cm^2 area for the rectangle

Answer:

Step-by-step explanation

full rectangle area (see figure) - small rectangle area

14 * 20 - [(14 - 9) *(20 - 11)] =

I am not sure if this is correct. But try it and let me know if it was

let's firstly convert the mixed fractions to improper fractions and then add/subtract.

[tex]\stackrel{mixed}{8\frac{1}{3}}\implies \cfrac{8\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{25}{3}}~\hfill \stackrel{mixed}{7\frac{1}{5}}\implies \cfrac{7\cdot 5+1}{5}\implies \stackrel{improper}{\cfrac{36}{5}} \\\\[-0.35em] ~\dotfill\\\\ 8\frac{1}{3}~~ +~~\left( -7\frac{1}{5} \right)\implies \cfrac{25}{3}+\left( -\cfrac{36}{5} \right)\implies \cfrac{25}{3}-\cfrac{36}{5}\implies \stackrel{\textit{using }\stackrel{LCD}{15}}{\cfrac{(5)(25)~-~(3)(36)}{15}}[/tex]

[tex]\cfrac{125-108}{15}\implies \cfrac{17}{15}\implies \stackrel{\mathbb{POSITIVE}}{1\frac{2}{15}}[/tex]

◊  Hello there! ◊

◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦

7x+4/3<6

Get rid of the denominator first by multiplying both sides by 3:

7x+4<18

Now, move all the  numbers to the right, using the opposite operation:

7x<18-4

7x<14

Divide both sides by 7:

x<2

Answer:

$84.40

Step-by-step explanation:

mowing: $9.40/hour

babysitting: $7.80/hour

4 hours mowing + 6 hours babysitting =

= 4 × $9.40 + 6 × $7.80

= $37.6 + $46.8

= $84.40

Answer:

$84.40

Step-by-step explanation:

$9.40 · 4 + $7.80 · 6 = ?

9.4 · 4 = 37.60

7.8 · 6 = 46.80

37.60 + 46.80 = $84.4

I hope this helps!!
