Answer:

The correct answer is B. -3.

Step-by-step explanation:

To solve this problem, we need to plug in -3 for all of the values of x in the equation. If we do this, we get:

f(x) = 2x + 3

f(-3) = 2(-3) + 3

Now, we can just simplify the expression found on the right side of the equation using PEMDAS. First, we should perform the multiplication.

f(-3) = -6 + 3

Next, we should add our final two terms together.

f(-3) = -3

Therefore, the correct answer is -3.

Hope this helps!

Write in slope-intercept form an equation of the line that passes through the points (−1,12) and (1,2).

zzz [600]

Answer:

$y=-5x+7$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

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

we have

the points (−1,12) and (1,2)

substitute

$m=\frac{2-12}{1+1}$

$m=\frac{-10}{2}$

$m=-5$

step 2

we know that

The equation of the line in slope intercept form is equl to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-5$

$point\ (1,2)$

substitute in the linear equation and solve for b

$2=-5(1)+b$

$b=2+5=7$

therefore

$y=-5x+7$

The width of a rectangle is 38 centimeters. the perimeter is at least 692 centimeters. write an inequality that represents all p

abruzzese [7]

Width of the reactangle = 38 cm

Minimum perimeter = 692 cm

Let the length of the rectangle be x cm

We know that,

Perimeter of rectangle = 2 * (length + width)

Since the perimeter should be atleast 692 cm. Therefore,

2 * (x + 38) > 692

2x + 76 > 692

2x > 692 - 76

2x > 616

x > $\frac{616}{2}$

x > 308

Hence, the length of the rectangle should be more that 308 cms.

Number 5 and 6 please?

GuDViN [60]

Answer:

5. Profit of Rs 1 per lemon

6. Rs 20

Step-by-step explanation:

5. Buy Rs 60 per 12 lemons = Rs 5 per lemon

Sell Rs 30 per 5 lemons = Rs 6 per lemon

Profit Rs 1 per lemon

6. Sell Rs 2500 per 100 pens = Rs 25 per pen

Profit per pen is 20% = (20/100)25 = 5

Cost price of a pen = 25 - 5 = 20
