Step-by-step explanation:

7 x 13    (split 13 into 10 + 3)

= 7 x ( 10 + 3)     (expand parentheses by distributive property)

= (7 x 10) + (7 x 3)

= 70 + 21

= 91

Write the equation of a line that is perpendicular to y = –x-6and that passes through the point
defon

Answer:

y = x + 5

Step-by-step explanation:

Perpendicularity: Slope is the opposite reciprocal. In this case with it being -1 aka -1/1, the slope will be 1 aka 1/1

Find the opposite reciprocal of the slope

m = -1 = -1/1

so,

m⊥ = 1 as the opposite reciprocal is 1/1

2 - Plug the new slope into y = mx + b

y = mx + b

y = 1x + b

y = x + b

3 - Plug the point values in replacing x and y to get alone and solve for the y intercept, b.

 y = x + b

-4 = -9 + b

+9  +9

5 = b

4 - Plug into the values into y = mx + b all together

y = mx + b

y = 1x + 5

y = x + 5

Hope this helps :)

Find the derivative of a power function using the power rule
taurus [48]
Let’s make up a random function, say:

f(x) = x^6

Now by power laws we can break this up into two parts:
f(x) = (x^2)*(x^4)

Since we are now multiplying two functions we can apply the product rule:

f’(x) = (2x)(x^4) + (x^2)(4x^3)

Now we can simplify since we are only dealing with x’s:

f’(x) = 2x^5 + 4x^5
f’(x) = 6x^5

If we do the power rule of our initial function, you will find that the two are equal.

Hope this helps!!

If the m<7 = 115 degrees, find the measure of <2
Vesna [10]
If they are complementary angles, then we know that they have a sum of 180°.

∠7=115°
∠7+∠2=180°
plug in the data we know
115+∠2=180
subtract 115 from both sides
65°=∠2

Answer=65°
