Step-by-step explanation:

Hey there!

The given points are; (-4,-1) and (4,2).

Use slope formula.

$slope(m) = \frac{y2 - y1}{x2 - x1}$

Put all values.

$m = \frac{2 + 1}{4 + 4}$

Simplify it.

$m = \frac{3}{8}$

Therefore, the slope is 3/8.

Hope it helps...

Answer:

"2 + 2(-3)(7) = negative

-2(27 ÷ 9)+4= negative

(14 ÷ -2)(-6)= positive

(4 - 10) - ( 8 ÷ ( -2))= negative

Step-by-step explanation:

2 + 2(-3)(7) = -40

-2(27 ÷ 9)+4= -2

(14 ÷ -2)(-6)= 42

(4 - 10) - ( 8 ÷ ( -2))= -2"

1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters

Bond [772]

Answer:

$x\leq 1.78$

Step-by-step explanation:

We are given that

Width of pool, b=4.5 m

We have to find the inequality which represents the possible lengths of the wading pool.

Let x be the length of wading pool

We know that

Area of rectangle= $length\times breadth$

According to question

Using the formula

$4.5x\leq 8$

Divide by 4.5 on both sides we get

$x\leq\frac{8}{4.5}$

$x\leq 1.78$

A football is thrown from the stadium. The height of this football can be represented by the polynomial -16t2 +32t + 20, where t

olasank [31]

Answer:

Step-by-step explanation:

related equation

-16t^2 + 32t + 20 = 0

-4t^2 + 8t + 5 = 0

Δ/4 = 16 + 20 = 36

t1 = (-4 + 6)/-4 = -1/2

t2 = (-4 - 6)/-4 = 5/2

-16(t+1/2)(t-5/2)

-16(2t+1/2)(2t-5/2)

-4(2t+1)(2t-5)

As part of a new fitness plan, Sabir walks on a treadmill at the same speed for 15 minuets every morning. The table shows the ca

Reil [10]

The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x
