. Solve the right triangle ABC given that side c = 17 cm and side b = 15 cm.

AURORKA [14]

A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
a = sqrt 64
a = 8 cm

Write the equation of a line that is parallel to y = -x + 7

Gnoma [55]

Answer:

y= -x-3

Step-by-step explanation:

A line is parallel to another line if their slope is the same. In this case the slope is -1 (-x is basically -1x). So far we have y=-x+b (We dont know what b is yet). next we can insert the coordinate back into the equation y=-x+b where 1 is the y and -4 is the x.

We get...

y= -x+b

1= -(-4)+b

1=4+b

b=-3

Our final equation is y=-x-3

Hope this helped

Solve: – 8 = -m 2m + 10

sukhopar [10]

Answer:

m = -18

Step-by-step explanation:

Step 1: Combine like terms

-8 = -m + 2m + 10

-8 = m + 10

Step 2: Subtract 10 from both sides

-8 - 10 = m + 10 - 10

-18 = m

Answer: m = -18

Tyler and Elena are on the cross country team.

romanna [79]

Answer:

Tyler ran 0.06 miles farther than Elena

Step-by-step explanation:

From the graph we can find the distance ran by Tyler in 10 minutes is approximately 1.24 miles

Given the equation for Elena's distances and times is

y=8.5x, where x is the distance in miles and y is the time in minutes, we can know the value of x when y = 10 minutes

$x=\frac{y}{8.5} =\frac{10}{8.5}=1.18$ miles

With this numbers at hand, we can infer Tyler ran 1.24 - 1.18 = 0.06 miles farther than Elena

What is the value of z for the equation 1/4z = –7/8 + 1/8z? –3 –7 3 7

DaniilM [7]

The first step for solving this equation is to determine the defined range.
$\frac{1}{4z} = - \frac{7}{8} + \frac{1}{8z}$ , z ≠ 0
Move the expression $\frac{1}{8z}$ to the left side of the equation and change its sign.
$\frac{1}{4z}$ - $\frac{1}{8z}$ = $- \frac{7}{8}$
Now we need to write all numerators above the least common denominator of 8z. This will change the equation to the following:
$\frac{1}{8z}$ = $- \frac{7}{8}$
Simplify the equation using cross multiplication.
8 = -56z
Switch the sides of the equation.
-56z = 8
Divide both sides of the equation by -56.
$z = -\frac{1}{7}$ , z ≠ 0
Lastly,, check if the solution is in the defined range to get your final answer.
$z = -\frac{1}{7}$
Let me know if you have any further questions.
