Answer:
log(35)/log(7)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]
You have b=7, a=35, so the rewrite is ...
[tex]\log_7(35)=\boxed{\dfrac{\log(35)}{\log(7)}}[/tex]

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator
Answer:
This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".

What would you multiply to make the y variable cross out?
-5x + y = -3
3x - 8y = 24
Answers
Answer:
Step-by-step explanation:
-40x + 8y = -24
3x - 8y = 24
-37x = 0
x = 0
0 + y = -3
y = -3
(0, -3)
Answer:
I will show you how to solve for x and y.
Step-by-step explanation:
-5x + y = -3
3x - 8y = 24
You can isolate y in the first equation, and substitute that into the second equation.
so to isolate y in -5x + y = -3, you would add 5x to both sides
this gives you y = 5x - 3
Then substitute this y into the equation below.
3x - 8(5x-3) = 24 (this way, the y variable disappears)
then distribute the 8 into the bracket
3x - 40x + 24 = 24
combine the variables
-37x + 24 = 24
isolate x by moving the constants to one side
-37x = 0
so x = 0
I am not sure if you want the rest, but here it is.
substitute x = 0 into one of the equations.
-5x + y = -3
-5(0) + y = -3
y = -3

Answers
Answer:
slope = -1/4, y-intercept = 50
Step-by-step explanation:
x=0 y=50
x=100 y= 25
y= mx+b
b= 50
25= 100 m +50
100m = - 25
m= -1/4
where m is the slope and b is the y intercept
Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?
Answers
Answer:
angle 1 is = 124 angle 2 is = 56
Step-by-step explanation:
supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]
[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]
[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]
[tex] \sf : \implies 40 + 5x = 180\degree[/tex]
[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]
[tex] \sf : \implies 5x = 140\degree[/tex]
[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]

Answers
Answer:
20, 68%, 0.687
Step-by-step explanation:
If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Help me ??????????????????
Answers
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2

f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6
