Answer:

The y-intercept is +2

using y=mx+b we can tell anything added is the intercept.

+2

Step-by-step explanation:

We know the standard equation is

y = mx + c

where m is the slope and c is the y-intercept.

By Comparing the given equation with the standard equation we get,

y-intercept = +2

Answer:

a. 300 minutes.

b. $53

explanation:

make equations from given information.

equation 1 from plan A :

20 + 0.11(n)

equation 2 from plan B :

14 + 0.13(n)

Solve them simultaneously,

14 + 0.13(n) = 20 + 0.11(n)

0.13(n) - 0.11(n) = 20 - 14

0.02(n) = 6

n = 300

insert n = 300 in any of the equation, to find cost.

14 + 0.13(n)

14 + 0.13(300)

$53

Answer:

f(x) = x² -5x factor this function

x(x-5) = 0   ----> either x =0 , or x -5 =0 then x =5

the two values of x make f(x) =0 are 0 and 5

we can check by substituting these two values

at x = 0 ----> f(0) = 0² - 5 * 0 ---> f(x) =0

at x =5 ----> f(5)= 5² -5 * 5 ---> f(x) =0

Answer:

1440°

Step-by-step explanation:

Each exterior angle of a 10 sided regular polygon =360/10=36°  

Each interior angle = 180°-36° =144°.  

Sum of all interior angles = 144°×10. = 1440°.

Solution:

1. Since the numbers must be divisible by 2 even numbers, all odd numbers are ruled out because odd numbers are not divisible with even numbers.

In this case, the numbers that are possible are:

2. Since the numbers must be divisible by 5, it rules out a few more numbers.

In this case, the remaining numbers are:

We can clearly tell that the only number that is divisible by 8, 5, and 4 is 80.

Thus, 80 is the number.

Step-by-step explanation:

A matrix of order 3×1 means it has 3 rows and one column.

[tex] \huge \red{ \begin{pmatrix} a \\\\b \\\\c \end{pmatrix} }[/tex]

Step-by-step explanation:

Substitute the value of y into the equation;

[tex]8x-2(4)=48[/tex]

Find the value of x.

Multiply;

[tex]8x-8=48[/tex]

Add 8 to each side;

[tex]8x=56[/tex]

Divide each side by 8;

[tex]x=7[/tex]

Answer:

x = 7

Step-by-step explanation:

Given:

Step-1: Substitute the y-variable in the equation (8x – 2y = 48)

Step-2: Simplify the L.H.S

Step-3: Add 8 both sides

Step-4: Divide 8 both sides

Answer:

A.15

Step-by-step explanation:

These two triangles are congruent triangles. This means that the side measurements can be found through a single multiplicative number.

All you have to do is divide 49 by 23 and get 2.130434783. You need that number to be specific

Next you want to multiply that number by the side length that corresponds to the length you are trying to find. In this case that is 7.  

7 x 2.130434783=14.9

14.9 rounds to 15

The rectangle is being translated.  It is moving up 3, so positive 3, and to the left 6, so -6.

Answer:

the fraction of the class that are boys is B/30, or b=30-g.

Both these answers work

Step-by-step explanation:

Answer:

8) 25.12

9) 15.07

10) 48.98

11) 1962.5

12) 20

13) r = 8.5

14) diameter: 72 radius: 36

Step-by-step explanation:

First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.

Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

Answer:

Step-by-step explanation:

So the total # of socks is 25 + 15+ 20, which equals 60.

theres ONLY 20 socks that are colorful, meaning that 20/60 are coloful.

20/60 simplified is 2/6, simply that even further its 1/3, 1/3 is a ration within itself. itll be 1:3

Answer:

1:3 (20:60)

Step-by-step explanation:

So the ratio of colorful socks to total socks is 20:60

This is how:

First write the number of colorful socks which is 20.

From the calculate the total number of socks( 20 + 25 + 15 = 60) which is 60.

Then put a colon and write 60

You need to write the number of colorful socks because that is what was mentioned first then the total number of socks because it was mentioned after the number of colorful socks.

So you can reduce 20:60 to its lowest term.

You write 20: 60 as a fraction [tex]\frac{20}{60}[/tex]

Then reduce [tex]\frac{20}{60}[/tex] to its lowest term which is [tex]\frac{1}{3}[/tex].

Then write [tex]\frac{1}{3}[/tex] as a ratio which is 1:3

Answer:

A

Step-by-step explanation:

A is the only one that has points that get hit only once when performing the vertical line test. All others get hit more than once per line.

Step-by-step explanation:

Since angles opposite congruent sides in a triangle are congruent, w=67.

Now, since the sum of the measures of the interior angles of a triangle is 180 degrees, x=180-67-67=46

Hey there!

4a + 3b + 2a

=> 4a + 3b + 2a

=> 4a + 2a - 3b

=> 6a - 3b

Therefore, 4a + 3b + 2a = 6a - 3b

[tex] \\\ \\ \\{x}^{2} + 2y + 8 {x}^{2} [/tex]

Answer:

Step-by-step explanation:

The vertex coordinates of  f(x) = ax² + bx + c  is  (h, k)

where:   [tex]h=\dfrac{-b}{2a}\ ,\qquad k=f(h)[/tex]

f(x) = - x² - 6x + 1       ⇒  a = -1   b = -6

So:

     [tex]h=\dfrac{-(-6)}{2(-1)}=\dfrac6{-2}=-3\\\\y=f(h)=-(-3)^2-6(-3)+1=-9+18+1=10[/tex]
