What is the slope and y-intercept from the table below?

Mathematics

Nataliya [291]3 years ago

Answer:

The equation is y = -5x + 55

Slope = -5

y-intercept = 55

Step-by-step explanation:

The given table shows the different coordinates of points on a straight line.

The general equation of a line is y = mx + b

where m is the slope and b is the y intercept.

Actually , here only 2 values are needed but there are 4 values                       given which is just to check whether our line is correct or not.

Substitute values of x and y in the equation.

Put (1,50),

50 = m + b    ----------(1)

Put (2,45),

45 = 2m + b    -----------(2)

Solve (1) and (2),

Slope , m = -5

y-intercept , b = 55

Hence , the equation is y = -5x + 55.

Answer: last option/D

Step-by-step explanation:

It says to do h(t) divided by g(t) so

1- you see that h(t) is 4t +2

2- you see that g(t) is 2t-1

3- you put h(t) on top of g(t)

So, it is 4t+2/2t-1

Tom [10]

Answer:

AC ≈ 2.18 units

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan70° = \frac{opposite}{adjacent} = \frac{BC}{AC} = \frac{6}{AC} ( multiply both sides by AC )

AC × tan70° = 6 ( divide both sides by tan70° )

AC = \frac{6}{tan70} ≈ 2.18 ( to the nearest hundredth )

mihalych1998 [28]

Answer:

He invested 3,000 at 7% and 4,000 at 9%.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=7,000 (1)

0.07x+0.09y=570 (2)

You can solve for x in (1)

x=7,000-y (3)

Now, you can replace (3) in (1) and solve for "y":

0.07(7,000-y)+0.09y=570

490-0.07y+0.09y=570

0.02y=80

y=80/0.02

y=4,000

Finally, you can replace the value of "y" in (3):

x=7,000-4,000

x=3,000

According to this, the answer is that he invested 3,000 at 7% and 4,000 at 9%.
