Answer:
170.6
Step-by-step explanation:
170.55
The tenths place is where the left 5 is.
1. Drop everything to its right.
170.5
2. Look at the first digit that was dropped. It is a 5. That means the last digit that remains goes up by 1 to 6.
Answer: 170.6
Answer:
170.6
Step-by-step explanation:
170.55 ≈ 170.6
When you are rounding numbers, you have to look at the digit after the digit you are rounding to. So if you are rounding to the nearest tenth, you need to look at the digit next to it which is the hundredth. If the hundredth is 1-4, then you round down. If the hundredth is 5-9, then you round up. Since the hundredth is 5, you round the 5 in the tenth place up to 6.

Inverse function details
Step-by-step explanation:
First, replace f(x) with y ⇒ f(x)=6x-19 ⇒ y=6x-19
Then y with x and x with y ⇒ y=6x-19 ⇒ x=6y-19
Solve the equation from for y:
x=6y-19
x+19=6y dividing with 6
1/6 x +(19/6) = y
Replace y with f−1(x) ⇒ f−1(x)= 1/6 x +(19/6)

Solve the system of equations down below Y-15=3x
-2+5y=-3
Answer:
Step-by-step explanation:
-5(y-15=3x) = -5y+75=-15x
add 15x to both sides and subtract 75 to both side
-5y+15x=-75
5y-2x=-3
13x=-78
and then both side divide by 13
x=-6
y-15=3(-6)
y-15=-18
Y= (-18) - 15 = -3
y=-3
and the answer will be (-6,-3)

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define Systems
y - 15 = 3x
-2x + 5y = -3
Step 2: Rewrite Systems
y - 15 = 3x
Add 15 to both sides: y = 3x + 15Step 3: Redefine Systems
y = 3x + 15
-2x + 5y = -3
Step 4: Solve for x
Substitution
Substitute in y: -2x + 5(3x + 15) = -3Distribute 5: -2x + 15x + 75 = -3Combine like terms: 13x + 75 = -3Isolate x term: 13x = -78Isolate x: x = -6Step 5: Solve for y
Define equation: y - 15 = 3xSubstitute in x: y - 15 = 3(-6)Multiply: y - 15 = -18Isolate y: y = -3Step 6: Graph Systems

This is a test please help me I have a D on math here’s the question!!
Find m∠CXY
Please help with this, this is for my test review!!!
Answer:
137°
Step-by-step explanation:
All angles in a triangle add up to 180° always.
Now imagine the two smaller shapes as a bigger triangle, CED. The measure of angle CED is 89°, and CDE is 48°. Do the math, and angle DCE is 43°.
But notice how the corresponding sides of the two smaller shapes are congruent. (CX=XE, and DY=YE) Meaning, the measure of angle C is equal to the measure of angle YXE.
We're almost there. CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180. 180-43 = 137°.

For the function F(x)=2x+1/
5x−2, evaluate F(−6).
Answer: f(-6) = 11/32
Step-by-step explanation:
f(x) = 2x+1/5x-2 TO solve for f(-6) input -6 into the function for x.
f(-6) = 2(-6) + 1/ 5(-6) - 2
f(-6) = -12 + 1 / -30 - 2
f(-6) = -11/ -32
f(-6) = 11/32

answer question 4 pleaseeeee
Answer:
a) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8
b) The average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32
Step-by-step explanation:
We are given function [tex]f(x)=4(2)^x[/tex]
We need to find Average rate of change
The formula used is: [tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}[/tex]
Part a) The interval is: x=1 to x=2
We have a= 1 and b=2
Finding f(a) i.e f(1)
[tex]f(x)=4(2)^x\\Put \ x =1\\f(1)=4(2)^1\\f(1)=4(2)\\f(1)=8[/tex]
Now finding f(b) i.e f(2)
[tex]f(x)=4(2)^x\\Put \ x =2\\f(2)=4(2)^2\\f(2)=4(4)\\f(2)=16[/tex]
Now finding average rate of change.
[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{16-8}{2-1} \\Average \ rate \ of \ change=\frac{8}{1}\\Average \ rate \ of \ change=8[/tex]
So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=1 to x=2 is 8
Part b)
The interval is: x=3 to x=4
We have a= 3 and b=24
Finding f(a) i.e f(3)
[tex]f(x)=4(2)^x\\Put \ x =3\\f(3)=4(2)^3\\f(3)=4(8)\\f(3)=32[/tex]
Now finding f(b) i.e f(4)
[tex]f(x)=4(2)^x\\Put \ x =4\\f(4)=4(2)^4\\f(4)=4(16)\\f(4)=64[/tex]
Now finding average rate of change.
[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{64-32}{4-3} \\Average \ rate \ of \ change=\frac{32}{1}\\Average \ rate \ of \ change=32[/tex]
So, average rate of change for the function [tex]f(x)=4(2)^x[/tex] over interval x=3 to x=4 is 32
Since the interval is increasing, so does our average rate of change increasing as function is also increasing.

Angle a is 5/3 of Angle b.
Find Angles a and b plz
Answer:
Angle a = 112.5°
Angle b = 67.5°
Step-by-step explanation:
Angle a + angle b = 180° (Supplementary Angles/angles on a straight line)
Let x = m<b
m<a = ⁵/3(x)
Therefore:
⁵/3x + x = 180
[tex] \frac{5x}{3} + x = 180 [/tex]
[tex] \frac{5x + 3x}{3} = 180 [/tex]
[tex] \frac{8x}{3} = 180 [/tex]
Multiply both sides by 3
[tex] \frac{8x}{3} \times 3 = 180 \times 3 [/tex]
[tex] 8x = 540 [/tex]
Divide both sides by 8
x = 67.5°
Angle a = ⁵/3(x) = ⁵/3(67.5) = 112.5°
Angle b = x = 67.5°
