HELP PLS!!! find x and y please show steps
loris [4]

Answer:

<h3>            x = 7 ,   y = 7√2</h3>

Step-by-step explanation:

The sum of measures of angles in triangle is 180°

so:

180° - 90° - 45° = 45°

two angles angles of the same measure, that means: x = 7

so:

      7^2+7^2=y^2\\\\y^2=7^2\cdot2\\\\y=\sqrt{7^2\cdot2}\\\\\bold{y=7\sqrt2}

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 104
olasank [31]

Answer:

Answer B: 1*10^2 times

Step-by-step explanation:

To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:

\frac{7*10^4}{7*10^2} = \frac{7*10^2*10^2}{7*10^2}=1*10^2 times

Therefore our answer agrees with the one shown as answer B.

Answer as many as you can please (write in slope-intercept form)
RoseWind [281]

Answer: See below

Step-by-step explanation:

For the first one, we are already given our slope. All we need to do is find the y-intercept, b.

y=-2x+b

6=-2(-3)+b

6=6+b

b=0

The slope-intercept form is y=-2x.

For the second one, we need to first find the slope using m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }.

m=\frac{1-13}{3-(-6)} =\frac{-12}{9}

Now that we have our slope, we can plug it into our slope-intercept form to solve for b.

y=-\frac{12}{9} x+b

3=-\frac{12}{9}(1)+b

-\frac{9}{4} =b

The slope-intercept form is y=-\frac{12}{9} -\frac{9}{4}.

For the third one, we are already given the slope, so all we have to do is find b.

y=-\frac{1}{2}x +b

-7=-\frac{1}{2} (-4)+b

-7=2+b

-9=b

The slope-intercept form is y=-\frac{1}{2} x-9.

For the last one, we need to first find the slope using m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }.

m=\frac{-8-2}{3-1}=\frac{-10}{2}  =-5

Now that we have our slope, we can plug it into our slope-intercept form and find b.

y=-5x+b

2=-5(1)+b

2=-5+b

7=b

Our slope-intercept form is y=-5x+7.
