Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = 1/2x+2

Step-by-step explanation:

First find the slope using y1-y2 over x2-x1 picking two points, the two I am using are (0,2) and (2,3). Once I use the formula, the slope is 1/2. The Y intercept (b) is where the line intersects it. (0,2) You know it is the y intercept because the x coordinate is 0. So the final equation would be y=(slope)x+ (y-int) so FINAL ANSWER: y=1/2x+2

Step-by-step explanation:

4×28/ 7×1 = 112/7

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

We already did that, and the GCF of 112 and 7 is 7.

We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.

112/7 = 16

and do the same for 3/4 out of 16 then add ur answers

Answer: 950.3

Step-by-step explanation:

so the formula for the volume of a sphere is 4/3*pi*r^3

so plugging your information into the formula, you would get 4/3(pi)(6.1)^3

6.1^3 is the same as

(6.1) times (6.1) times (6.1)

this equals 226.981

now you have 4/3(pi)(226.981)

now you do 226.981/3 which equals 75.660333

multiply that by 4➡️ 302.6413333333333

now you have to multiply by pi (3.14)

302.6413333333333*3.14=

950.2937866666667

you have to round to the 10ths place

so your answer is 950.3 m cubed.

Which of the following angles can be added together to create 177°? Explain your answer using words.

Answers

First you’d look for ones units that add up to 7, so in this case (5)4 and (6)3

Add 54 and 63 to get 117

Subtract 117 from 177 to get 60

25 and 35 equal 60 (I just know that from common knowledge I have no idea how to explain that in words)

So 25 + 35 + 54 + 63 = 177

Given the inequality expression 4 + x > 6, we need to solve for x and graph the equivalent graph of the function;

Given

4 + x > 6

Subtract 4 from both sides of the inequality

4 + x - 4 > 6 - 4x > 6 - 4x > 2

Next is to graph the solution x > 2 on the number line.

Since the inequality sign is greater than sign, the line arrow will point towards the right of the number line and the circle will be an open circle.

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.

Answers

I am not sure I’m sorry

Answer:

-3 & -5

Step-by-step explanation:

let the two numbers be x and y

x + y = -8. sum of the numbers is -8

x - y = 2. difference(-) of the numbers is 2

now we add the two equations

x + x + y - y= -8 + 2

2x = -6

x = -6/2. = -3

substitute value of x in second equation to get y

-3 - y = 2

-y = 2 + 3

-y = 5

y = -5

The function g is defined by g(x) = -3x + 2. Which statements are true? Select ALL that apply.
f{-2) is greater than g(-2).
f{-1) is less than g(-1).
f{0) is greater than g(0)
f(1) is less than g(1).
f(2) is greater than g(2).

Answers

Answer:

f{0) is greater than g(0) and f(2) is greater than g(2).

Step-by-step explanation:

f{0) is greater than g(0) = f(0)=8  and g(0)=2

f(2) is greater than g(2) = f(2)=8 and g(2)= -4

The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

What is the general equation of parabola?

The general equation of a parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

where (h,k) is the coordinate of the vertex of the parabola.

The equation of the parabola with vertex (1,9) can be written as,

[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]

Now, the value of a can be found by putting one zero of the parabola,

[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]

Thus, the equation of the parabola can be written as y=-(x-1)²+9.

A.) The value of the two functions when the value of x is -2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]

[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]

Therefore, f(-2) is less than g(-2).

B.) The value of the two functions when the value of x is -1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]

[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]

Therefore, f(-1) is equal to g(-1).

C.) The value of the two functions when the value of x is 0 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]

Therefore, f(0) is greater than g(0).

D.) The value of the two functions when the value of x is 1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]

[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]

Therefore, f(1) is greater than g(1).

E.) The value of the two functions when the value of x is 2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]

Therefore, f(2) is greater than g(2).

Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).
