Answer:

see below

Step-by-step explanation:

y +1=2(x + 7)

This equation is in point slope form

Let's put the equation in slope intercept form

Distribute

y+1 = 2x +14

Subtract 1 from each side

y+1-1 = 2x+14-1

y = 2x+13

This is in y= mx+b where m is the slope and b is the y intercept

The slope is 2 and the y intercept is 13

Help me find the area of the question c please
Marysya12 [62]

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = \frac{a+b}{2} h

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16

Hence the area of shape C = 16 square units

The sum of two numbers is 50. The first number is 43 less than twice the second number.
Tomtit [17]
X, y - the numbers

The sum of the two numbers is 50.
x+y=50 \\
x=50-y

The first number is 43 less than twice the second number.
x=2y-43 \\ \\
50-y=2y-43 \\
-y-2y=-43-50 \\
-3y=-93 \\
y=31 \\ \\
x=50-y=50-31=19

The numbers are 19 and 31.
