can anyone tell me the answer for b

Answer:

y = - x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m = [tex]\frac{-1-1}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

The line crosses the y- axis at (0, - 1 ) ⇒ b = - 1

y = - x - 1 ← equation of line

Answer:

y= - x -1

Step-by-step explanation:

ran it through Desmos

I can't find a way to expllain  

it if i would put y= - 1 (becaues remember -1 is where the lines intersected with the y axis)

all there would be was a straight

line across -1 but since its goin  down 1

you need the - x     to give it a negative tilt

how u UNderstan

Answer:

y=7x

Step-by-step explanation:

one way to think of it is by taking a y value from the table like (for example) 42 so you would do something like 42 divided by x = 6, or u could just do 42 divided by 6 which gives u 7. u can check ur answer by plugging in an x value to the equation. so for example we can plug in 8 to y=7x which is basically 7x8 and 7x8 is 56 which is true to the table.

Step-by-step explanation:

To find if a function intervals are possible, make sure the points are above the x axis.

The graph is getting positve around x=-3 but it isn't positive yet.

The graph is positve until x=-1

The graph becomes positive again again at x=2 and is positive infinitely forever.

So let set up our interval

We are going to start at -3 since that where it start getting positive, we then going to use the greater than sign since it get positve as we go to the right as of right now. We use the greater than becuase we are not going to include -3 as our solutions.

We then use a less than sign since the answer must be less than -1 becuase around-1 it start getting negative.

It becomes positive again at x=2 so since we going to left to right use the greater than sign becuase we are not including 2.

It infinitely becomes positive so our interval is x must be cause greater than w becuase it can be any interval greater than two.

[tex] - 4 > x < - 1[/tex]

and

[tex] 2 < x[/tex]

The roots or zeroes are the x intercept of the graph,(when y=0, what is the x value.)

The x intercepts are -3 and 2.

Answer:

32%

Step-by-step explanation:

First find the whole, the total number of toy cars:

160  on the wall} + 340 \text{ in display case} = }{500}  total toy cars}

160 on the wall+340 in display case=500 total toy cars

Method 1: Set up a proportion

Set up an equation of the form:

whole

part

​

= }{100}

100

percent

​

Assign the variable xx to the unknown value:x}=

x=

percent

The question asks what }percent of all the toy cars is 160

Substitute the known values with the numbers given in the problem, and the unknown value with xx:

\frac{\color{red}{160}}{\color{orange}{500}}=

500

160

​

={100}

100

x

​

Solve for xx:

100}{160}=

100⋅160=

{500}

500⋅x

Cross multiply

16000}{500}=

500

16000

​

=

{500x}{500}

500

500x

​

Divide both sides by 25

{32\%}=

32%={x}

x

Simplify

Method 2: Find percent directly

Find \(160\) out of \(500\) as a decimal:}

Find 160 out of 500 as a decimal:

{160} {500}}=

500

160

0.32

\text{Convert decimal to percent:}

Convert decimal to percent:

The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.

Since Ryan has a toy car collection consisting of 160 toy cars he keeps on the wall and 340 he keeps in a display case.

So here the percentage be like

[tex]= 160 / (160 + 340)[/tex]

= 32%

Hence, The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.

Answer:

[tex]x=\frac{21}{4}[/tex]

[tex]y=\frac{21}{2}[/tex]

Step-by-step explanation:

equation (1): [tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]

equation (2): y=2x

solve the system by substitution

step1: sub (2x) for y in equation 1:

[tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]

[tex]\frac{1}{2} (2x+2x)=\frac{21}{2}[/tex]

step2: simplify the expression:

[tex]\frac{1}{2} (4x)=\frac{21}{2}[/tex]

[tex]2x=\frac{21}{2}[/tex]

(divide by 2 for both sides)

[tex]x=\frac{21}{4}[/tex]

To find the value for y sub 21/4 for x in equation 2:

y=2x

y=2×(21/4)

[tex]y=\frac{21}{2}[/tex]

Answer:

2/7

Step-by-step explanation:

This is easy! No need to over think it btw!

1) whenever you divide by a whole number such as in this case;4. You need to put a 1 under 4... like this: 4/1 (so it can become a fraction!)

2) Use KEEP, CHANGE, FLIP when you are dividing fractions!

    8/7 --> you keep that number

    ÷ ---> × = you change the division sign into multplication sign

    4 ---> 1/4  = you put 1 over 4 and flip it which you get from 4/1  --> 1/4

3) Your would look like this....

   8/7 * 1/4 = ?

4) Muliply horizontally; 8 * 1 = 8 , 7 * 4 = 28

5) You get 8/28   Don't forget to simplify!!!

6) 8/4 / 32/4 = 2/7

ALSO, here's an example of KEEP, CHANGE, FLIP:

Answer: 7.33980582 x 10^0

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

The expression in scientific notation is 7 ×10^5

The four basic mathematical operations are Addition, subtraction, multiplication, and division.

Given that the terms are;

(8.4×10^8) ÷ (1.2×10^3)

Step 1: Divide the numerical parts:

8.4 ÷ 1.2 = 7

Step 2: Subtract the exponents:

10^8 /10^3 = 10^5

Now Putting the numerical part and the exponent together, we get:

7 ×10^5

Hence, the result of the expression in scientific notation is; 7 ×10^5
