Answer:

The correct option is 1.

Step-by-step explanation:

The given set of equations is

Equation A: c = 2d + 1

Equation B: c = 3d + 5

Using equation A and equation B, equate the value of c.

$2d+1=3d+5$

$1-5=3d-2d$

$-4=d$

The value of d is -4. So the value of c is

$c=2d+1=2(-4)+1=-7$

The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.

Let u = <-8, -9>. Find 7u. (2 points)

Multiplying a vector by a scalar means to multiply each coordinate of the vector by said scalar.

So, we must multiply both entries by 7:

$u=(-8, -9)\implies 7u=(-8\cdot 7, -9\cdot 7) = (-56, -63)$

The line should equal 180 degrees, so we would subtract 122 from 180 to get 58 degrees. Since the triangle is equilateral, each angle is the same measure, so I believe m<1 should be 58 degrees.
