graph the following features: slope= -3/2 y intercept = 2

Answers

Using the given information the equation of the line is y = -3/2x + 2

Now replace x with any number and solve for y. Do this twice to get to points to plot on the graph:

Using X = 0:

y = -3/2(0) + 2, y = 2

First point is (0,2)

Now X = 4:

y = -3/2(4) + 2 = -6 + 2 = -4

Second point = (4,-4)

Jada measured the height of a plant in a science experiment and finds that, to the nearest 1/4 of an inch, it is 4 3/4 inches.

How large could the percent error in Jada’s measurement be? Remember her error is 1/8 (.125) of the orignial height. Round to the nearest tenth of a %.

Answers

Answer: 2.6%

Step-by-step explanation:

4 3/4 = 4.75 which I'll be using because its easier for me

0.125 / 4.75 = 0.0263157895

0.0263157895 * 100 = 2.63157895

2.63157895%

Geometry- Solve the portion. Question#3​

Answers

Answer:

[tex]a=1[/tex]

Step-by-step explanation:

First let's put our equation[tex]\frac{1}{a+3}=\frac{4}{16}[/tex]Cross - Multiply[tex]4a+12=16[/tex]Subtract both sides by 12[tex]4a=4[/tex]Divide both sides by 4[tex]a=1[/tex]

Answer:

a=1

Step-by-step explanation:

Hi there!

We are given the proportion [tex]\frac{1}{a+3} =\frac{4}{16}[/tex], and we want to solve it for the variable, a

Before we start, we can simplify 4/16 to 1/4, since 4 is the GCF of the numerator and denominator of that fraction. Simplifying the fraction will make the computation easier, as the numbers are smaller.

Therefore, the proportion will now be:

[tex]\frac{1}{a+3} =\frac{1}{4}[/tex]

Because this is a proportion, we can cross multiply in order to solve for a; to do that, multiply a+3 by the expression that is on the top right (in this case, 1). Also multiply 4 by the expression that is on the top left (in this case, 1). Then, set them equal to each other, since it is still an equation :)

1(a+3)=4(1)

Multiply

a+3=4

Subtract 3 from both sides

a=1

Question 2: They provide us with the first angle of 139 degrees. Angle N corresponds with the first angle. Therefore angle N must be the same as the first angle, equaling 139 degrees.

An automatic doughnut machine can produce 1500 doughnuts in 9 hours.
How long would it take the machine to make 300 doughnuts?

Answers

Answer:

1 hr, 48 minutes

Step-by-step explanation:

you can create a proportion:

doughnuts/hours = doughnut/hours (h)

1500/9 = 300/h

cross-multiply to get:

1500h = 2700

h = 27/15

h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60

Devon's father is installing new wood flooring. He bought boards that are 10 ft long, 3/4 in. thick, and 11/24 in. wide. Determine the number of boards Devon's father will need for a 10 ft by 16 1/2 ft room. Plz plz help and the way to solve it plz!!!

Answers

Answer:

36 boards

Step-by-step explanation:

The boards are as long as the room, so I only had to worry about the width. If the boards were 1/2 ft wide, I would need 2 boards for every foot of width. For 16 ft, I would need 32 boards.

Instead of dividing, I wrote the equivalent multiplication by multiplying by the reciprocal of 11/24 (the reciprocal of 11/24 is 24/11)

I simplified by dividing both 2 and 24 by 2, and both 11 and 33 by 11.

Therefore he needs 36 boards

A grandfather is ten times older than his granddaughter. He is also 54 years older than
her. How old is each of them?

Answers

Grandad = 60
Granddaughter = 6

Answer:

The present ages of the granddaughter and grandfather are 6 and 60 years.

Step-by-step explanation:

Let the present age of granddaughter be x years.

So, the present age of grandfather is 10x years.

According to the given condition, we have

10 x = 54 + x

9 x = 54

x = 6

10 x = 60

age of grandfather is 60

age of granddaughter is 6

Hence, the present age of granddaughter is 6 years and that of grandfather is 60 years.

What is the slope intercept equation from the graph?


Please help thank u

Answers

Answer:

the desired equation is y = (-3/2)x + 3

Step-by-step explanation:

Two points through which the graph passes are (0, 3) and (2, 0).  (0, 3) is the y-intercept.  Thus, the slope-intercept equation y = mx + b becomes

y=mx + 3.  Borrowing the coordinates of (2, 0) and substituting them into this last result, we get

0 = m(2) + 3,

which, after having been solved for m, gives us m = -3/2

and so the desired equation is y = (-3/2)x + 3.
