What is the solution to the system of equations represented by these two lines?

The solution of two equations/lines is their intersect point.
Therefore, there can only be one intersection point/solution, because these lines are neither parallel or identical.
In the graph you can see that they intersect at (x,y)=(2,3) which is your solution and option b or d as one of them seems to be mistyped :)

@question2
y=kx+b

both your equations share the same k=-2:
y=-2x+3
y=-2x-1

therefore these lines are parallel and don't have any intersection as they are always at different y values (the b)

Find the missing angel

kolezko [41]

Answer:

x=25°

Step-by-step explanation:

The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:

$x+y=90$

Insert the known values:

$x+65=90$

Solve for x. Subtract 65 from both sides:

$x+65-65=90-65\\\\x=25$

The missing angle, x°, is 25°.

Azmyne decided to spend 6 1/2 hours studying over the weekend. She spent 1 1/4 hours studying on Friday evening and 2 2/3 hours

nata0808 [166]

Answer: $2\ \dfrac{7}{12}\ \text{hours}$

Step-by-step explanation:

Given

Azmyne decided to study a total of $6\ \frac{1}{2}\ hours$

She spent $1\ \frac{1}{4}\ hours$ on Friday and $2\ \frac{2}{3}\ hours$ on Saturday

Hours spent on Friday

$\Rightarrow 1\ \frac{1}{4}=\frac{5}{4}\ hours$

Hours spent on Saturday

$\Rightarrow 2\ \frac{2}{3}=\frac{8}{3}\ hours$

She must study for

$\Rightarrow \dfrac{13}{2}-\dfrac{5}{4}-\dfrac{8}{3}\\\\\Rightarrow \dfrac{13\times6-5\times3-8\times4}{12}=\dfrac{78-15-32}{12}\\\\\Rightarrow \dfrac{31}{12}=2\ \frac{7}{12}\ \text{hours}$

2. A sprinter is running at the end of a race and begins to tire. Her velocity is 8.55 m/s and is decelerating at -0.15m/s for t

GrogVix [38]

Step-by-step explanation:

using the formula :

2.d.s = V²-Vo²

2(-0.15) (60) = V² - (8.55)²

-18 = V² - 73.1

V² = 73.1 - 18

V² = 55.1

=> V = √55.1 = 7.4

so, the velocity when she ends the race =

7.4 m/s
