Answer:

a) 2

b) 1

c) y =mx+b

Step-by-step explanation:

Slope = rise/run = Δy/Δx = 2/1 =2   [Δ means difference between 2 values]

To find slope we need to find by how many difference do the x and y increases or decreases. Here y increases by 2 and x increases by 1.

The constant just another way of asking y-intercept.

The slope-intercept form y=mx+b. [m=slope, b= y-intercept]

We will choose point (1,3) to input into the equation. You can use any point it would give the same answer.

3 = 2×1 +b

3 = 2 +b

b = 3-2

b = 1

Answer:

1.92

Step-by-step explanation:

y = k/x^2

k = yx^2

k = 3 * 4^2

k =3*16=48

y = 48/x^2

y = 48/ 5^2

y = 48/25

y=1.92

Answer:

the first option

Answer: 880000

Step-by-step explanation: 8.8 x 10^ 5 = 880000

An ant can carry 0.044 pound of weight.

Important information:

Weight of an ant in standard form is:

[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound

[tex]8.8x10^{-6}=0.0000088[/tex] pound

They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:

[tex]0.0000088\times 5000=0.044[/tex]

Therefore, an ant can carry 0.044 pound of weight.

Answer:

The area of the triangle is 351cm^2.

Step-by-step explanation:

To find the area of a triangle, the formula is (1/2) x base x height. In this case, the height would be a line that cuts straight through the center of the triangle. However, this height is not given to us. We can still find it through Pythagoras' Theorem though.

Let A be the tip of the triangle, and B and C be the points on either side of the triangle. Assuming an imaginary line that cuts the triangle in a symmetrical half, let T be the point at the end of the line, directly below point A.

Using Pythagoras' Theorem,

AB^2 = AT^2 + TB^2

AT^2 = AB^2 - TB^2

AT^2 = 30^2 - (26/2)^2

AT^2 = 30^2 - 13^2

AT =

[tex] \sqrt{ {30}^{2} - {13}^{2} } [/tex]

AT = 27.0370116692

So the length of AT is our height. We can now find the area of the triangle.

Area of triangle = (1/2) x 26cm x AT

Area of triangle = 351.4811516996

Area of triangle = 351cm^2 (To 3s.f.)

Answer:

k = (1 , 4)

Step-by-step explanation:

here's your solution

==> k^2 - 5k + 4. [ is expression ]

==> by using middle term split

==> k^2 - 4k - k + 4

==> taking common from each

==> k(k - 4) - 1 (k - 4)

==> (k - 1) , (k - 4).

==> k - 1 = 0

==> k = 1

==> k - 4 = 0

==> k = 4

hence , k = (1 , 4)

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

To find the slope of a line with 2 given points, you use the formula

m=y2-y1/x2-x1

Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2

4/-2 equals -2

The slope is -2

Answer:

$2 for 1 rose bush and $2 for one shrub

Step-by-step explanation:

32=2x+14y

26=11x+2y

32=2(2)+14(2)

32=4+28

32=32

26=11(2)+2(2)

26=22+4

26=26

Since both equations come out correct the cost of 1 rose bush is 2 dollars and the cost of one shrub is 2 dollars. kinda cool

Answer:

The cost of one rose bush is $2 and the cost of one shrub is $2.

Step-by-step explanation:

Let r represent the cost of 1 rose bush and s the cost of 1 shrub.

Kali's expenditure

2r + 14s = 32

Divide each term by 2

r + 7s = 16 ------ (i)

Kim's expenditure

11r + 2s = 26 ------ (ii)

From equation (i)

r = 16 - 7s

11(16 - 7s) + 2s = 26

176 - 77s + 2s = 26

-75s = 26 - 176

-75s = -150

s = -150/-75 = 2

r = 16 - 7s = 16 - 7(2) = 16 - 14 = 2

The cost of one rose bush is $2 and the cost of one shrub is $2
