Answer:

C. Slope= -1/2, y-intercept= 2

Step-by-step explanation:

The y intercept is where it crosses the y axis

It crosses at y=2

We need two points to find the slope

(0,2) and (4,0)

We can use the formula

m = (y2-y1)/(x2-x2)

= (0-2)/(4-0)

=-2/4

=-1/2

It’s C because the y-intercept is where the point intersects on the y-axis and the slope goes up one and over 2 to the left making it negative

Add all the Braves score. Add all the Giant score. Then, you take the Giant's score and subtract it with the Braves score. :)

the equation a=1/2(b1+b2)h can be used to determine the area, a, of a trapezoid with height, h, and base lengths, b1 and b2. whi

Answer:

b₁ = (2a – b₂h)/h; b₁ = (2a)/h – b₂; h = (2a)/(b₁ + b₂)

Step-by-step explanation:

A. Solve for b₁

a = ½(b₁ + b₂)h Multiply each side by 2

2a = (b₁ + b₂)h Remove parentheses

2a = b₁h + b₂h Subtract b₂h from each side

2a - b₂h = b₁h Divide each side by h

b₁ = (2a – b₂h)/h Remove parentheses

b₁ = (2a)/h – b₂

B. Solve for h

2a = (b₁ + b₂)h Divide each side by (b₁ + b₂)

h = (2a)/(b₁ + b₂)

2. What is the value of x if the angles within a triangle are 2x +1, 7x-2 and 3x +5?

noname [10]

Answer:

$x=14.67\\$ °

Step-by-step explanation:

The sum of all the three angles of any triangle is 180°

Putting sum of all the angles given equals to 180°

$(2x+1)+(7x-2)+(3x+5)=$ $180$ °

$2x+7x+3x+1-2+5=180$ °

$12x+4=180$ °

$x=\frac{180-4}{12}$

$x=14.67\\$ °

The value of the x is found on solving the given angles of the triangles.
