Answer:
Step-by-step explanation:
Replace g(x) with y, then switch the x and y variables:
[tex]x=\frac{-5y+5}{2}[/tex]
Solve for the new y value, multiply by 2:
[tex]2x=-5y+5[/tex]
Subtract 5 on both sides:
[tex]2x-5=-5y[/tex]
Divide by -5 on both sides:
[tex]-\frac{2x-5}{5} =y[/tex]
Distribute the negative sign and rearrange:
[tex]\frac{-2x+5}{5} =\frac{5-2x}{5} =g^-^1(x)[/tex]
Answer:
A. g⁻¹(x) = (5 - 2x)/5Step-by-step explanation:
Given functiong(x) = (-5x + 5)/2Find the inverse of g(x)SolutionSubstitute x with y and g(x) with x and then solve for y:
x = (-5y + 5) /22x = -5y + 55y = -2x + 5y = (-2x + 5)/5y = (5 - 2x)/5Replace y with g⁻¹(x)
g⁻¹(x) = (5 - 2x)/5Correct choice is A

y = 1/2x - 4 Slope: X-intercept: Y-intercept:
Answer:
Slope = [tex]\frac{1}{2}[/tex] , X-intercept = 8 , Y-intercept = -4
Step-by-step explanation:
the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept
since m = [tex]\frac{1}{2}[/tex] and b = -4, we can say our slope is [tex]\frac{1}{2}[/tex] and y intercept is -4.
Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x
0 = [tex]\frac{1}{2}[/tex]x - 4
add 4 to both sides,
4 = [tex]\frac{1}{2}[/tex]x
multiply by 2 on both sides,
4*2 = x
8 = x
x = 8
so our x-intercept is 8
7k − 5k + 8 = −4
7(−6) − 5(−6) + 8 = −4
−42 + 30 + 8 = −4
−12 + 8 = −4
−4 = −4
is it me or 5(-4)= -30???
Answer:
-6
Step-by-step explanation:
7k − 5k + 8 = −4

Please help me ASAP please
9514 1404 393
Answer:
1
Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.

Determine if the sequence is arithmetic, geometric, or neither. For arithmetic and geometric sequences, identify the common difference or common ratio. For neither, enter n/a. {-45, -38, -31, -24, ...}
Arithmetic, Geometric, or Neither?
Common difference, ratio, or neither?
9514 1404 393
Answer:
Arithmeticcommon difference = 7Step-by-step explanation:
First differences are ...
-38 -(-45) = 7
-31 -(-38) = 7
-24 -(-31) = 7
The first differences are constant, so this is an arithmetic sequence with a common difference of 7.

A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.
Which of the following is the correct scale?
1:72
1:12
1:144
5:60
Answer:
1:144
Step-by-step explanation:
if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches
Answer:
1:144 inches
Step-by-step explanation:
how do i simplify something like -2x(2 – 5x) - 3x^2 this?

Erin buys 3 packs of potatoes costing £3 each, 3 packs of carrots for £2 per pack, and 4 turnips costing 60p each.
If she pays with a £20 note, how much change would she get?
Answer:
£2.6
Step-by-step explanation:
Given data
3 packs of potatoes costing £3 each= 3*3= £9
3 packs of carrots for £2 per pack= 3*2= £6
4 turnips costing 60p each= 4* 0.60= £2.4
Hence the total cost = 9+6+2.4= £17.4
Hence the change will be 20-17.4
= £2.6
[tex]\frac{2y-1}{15} =\frac{y}{10}[/tex]
Answer:
y = 2
Step-by-step explanation:
Given
[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2

A submarine was 600 feet
below sea level. If it
ascends 250 feet, what is
its new position?
Answer: Down below
Step-by-step explanation:=(600-250)m=350m
Answer:
Step-by-step explanation:
The initial position of the submarine was 600 ft below sea level
Then it ascends, i.e., goes up or moves up 250ft.
So now it is (800–250=)550 ft below sea level. I hope this helps.
