Identify the slope and y-intercept for the linear equation below.
y = 1/3x+7

Answers

Answer:

Slope is 1/3.

Y-intercept is 7.

Step-by-step explanation:

y = mx + b is the slope-intercept form.

m = slope

b = y-intercept

In the equation, y = 1/3x + 7

m = 1/3

b = 7

Therefore, slope is 1/3 and y-intercept is 7.

Hope this helped! <3

Answer:

Slope is 1/3 and the y- intercept is 7

Step-by-step explanation:

Since the equation is y = mx+b, we know that 1/3 is the slope since m represents the slope and b represent the y-intercept, meaning 7 is the answer.

Answer:

  x = 90 degrees

Step-by-step explanation:

There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.

  arc DE = 2×∠DFE = 60°

  arc EF = 2×∠ECF = 60°

  arc CF = 2×∠CEF = 60°

Then arc DEC is ...

  arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°

Angle DBC is half the measure of this arc, so is ...

  ∠DBC = 180°/2 = 90° = x

the area of rectangular plot of land fenced all round is 2000 sq. yards and the total length of fencing 180 yards. find the length and width of plot

Answers

9514 1404 393

Answer:

length: 50 ydwidth: 40 yd

Step-by-step explanation:

The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...

  x(90 -x) = 2000 . . . . where x is length or width

  x^2 -90x +2000 = 0 . . . . rearrange to standard form

  (x -40)(x -50) = 0 . . . . . . . factor

  x = 40  or  x = 50

The dimensions of the rectangular plot are 40 yards by 50 yards.

Part B 1/2-5/8-7/9=7/9-5/8-1/2

Answers

Answer:

False

Step-by-step explanation:

1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2

Add 5/8 to both sides.

1/2 - 7/9 = 7/9 - 1/2

Factor -1 out of the right side.

1/2 - 7/9 = -1(-7/9 + 1/2)

1/2 - 7/9 = -1(1/2 - 7/9)

1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.

A nan brought a cow for $200 and sold it to gain $50. What was his gain as a percentage of the cost price?​

Answers

Answer:

25%

Step-by-step explanation:

Given that,

The cost price of a cow, CP = $200

Gain = $50

We need to find the gain percentage of the cost price.

SP = CP + gain

= 50 + 200

= $250

[tex]\text{Gain}\%=\dfrac{\text{Gain}}{CP}\times 100\\\\=\dfrac{50}{200}\times 100\\\\=25\%[/tex]

So, the gain percent is 25%.
