angle C is a right angle and given the conditions c=2 B= 45 degrees, solve for the side lengths of the right triangle

1 answer:

8 0

Since the triangle is 45,45,
90 arrangement. We can use the special triangle trick. Which gives us 2,2 and square root of 2 times 2

Find the equation of the line that passes through both (5,1) and (8,-2)

Georgia [21]

Let $f(x) = ax+b$ be the line that passes through both points.

We know that $f(5) = 1$ and $f(8) = -2$ . So:

$\begin{cases}5a+b = 1 \\ 8a+b = -2\end{cases}$

Solving the system, we get that a= -1 and b = 6.

So the line is equal to $f(x) = 6-x$ .

Answer:

Step-by-step explanation:

$x = 5 - 2y \\ y = 3(5 - 2y) - 8 \\ y = 15 - 6y - 8 \\ y = 7 - 6y \\ 7y = 7 \\ y = 1$

$x = 5 - 2y \\ x = 5 - 2 = 3 \\$

2(t+1)=10. need the answer for t I got the rest just can't get t

harkovskaia [24]

Answer: $t=4$

Simplify both sides of the equation

$(2)(t)+(2)(1)=10(Distribute)\\2t+2=10$

Subtract 2 from both sides

$2t+2-2=10-2\\2t=8$

Divide both sides by 2

$\frac{2t}{2} =\frac{8}{2} \\t=4$

Bryan made up a game. Each team starts with seven points. Each time a team answers a question correctly, they earn five points.

Margaret [11]

The given equation is:
t = 7 + 5q
where:
t is the total number of points
q is the questions answered correctly

We are given that the total of correct answers is 6 and we want to find the total number of points. Therefore, all we have to do is substitute with the number of answers in the given equation to get the total points as follows:
t = 7 + 5q
t = 7 + 5(6)
t = 7 + 30
t = 37 points
