Answer:

The line of the equation in the point-slope form of the line passing through the point (3, -1) and having slope 1/2 will be:

y +1 = \frac{1}{2} (x-3)

Please check the attached graph.

Step-by-step explanation:

Given

  • The slope m = 1/2
  • The point (3, -1)

<u>Point slope form:</u>

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

m = 1/2

The point (x₁, y₁) = (3, -1)

substituting the values m = 1/2 and the point  (x₁, y₁) = (3, -1)  in the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

y - (-1) = \frac{1}{2} (x-3)

y +1 = \frac{1}{2} (x-3)

Thus, the line of the equation in the point-slope form of the line passing through the point (3, -1) and having slope 1/2 will be:

y +1 = \frac{1}{2} (x-3)

Please check the attached graph.

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive
Alenkinab [10]

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = \frac{11}{100}*145 = \frac{1,595}{100} = 15.95

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = \frac{4}{100}*145 = 5.8 ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

Write these expressions as simply as possible
harkovskaia [24]
So it is asking you to group like term so
x terms can be grouped/added/subtracted to other x terms, but not to x^2 or x^3 terms
x^2 terms to x^2 and so on so

1.  9-3k+5k=
9+(5k-3k)=
9+2k

2.  k^2+2k+4k=
k^2+(2k+4k)=
k^2+6k=

Ashton used 12.6 gallons of gasoline to drive his car on a weekend trip. he averaged 21.5 miles per gallon. about how many miles
7nadin3 [17]

Answer: 270.9 miles.

Step-by-step explanation:

The formula  we use here is :

\text{Distance=Speed * Number of gallons of gasoline}

Given : Ashton used 12.6 gallons of gasoline to drive his car on a weekend trip. he averaged 21.5 miles per gallon.

Then \text{Distance traveled }=12.6\times21.5=270.9\text{ miles}

Hence, he traveled 270.9 miles.

Question 1 (1 point)
Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation 48=-8(\frac{3b}{4}+2) you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

(-)(-)=+\\(+)(+)=+\\(+)(-)=-

Now you can apply the Distributive property:

48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16

Simplifying the equation, you get:

48=-6b-16

You can observe that this equivalent equation matches with the equation provided in option B.
