Can anyone please helping me out with question 3 it’s my last question and I can’t get it!!!
Answer:
x=1, y= -1
Step-by-step explanation:
x = 2y +3
3x -y = 4
Use the substitution method because we have x= something in terms of y
3 (2y+3) -y = 4
6y + 9 -y = 4 subtract 9 from both sides
6y -y = 4-9 combine like terms
5y = -5 divide both sides by 5
y = -1
x= 2*(-1) +3 = -2+3 = 1

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Answer:
The average rate of change
[tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]
At t = 1
[tex]\frac{dh}{d t} = 70 (1) - 16(2t) = 38[/tex]
at t=3
Step-by-step explanation:
Step(I):-
The given function h(t) = 3+70t - 16t²
[tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]
The [tex]\frac{dh}{d t} = 70 (1) - 16(2t) =0[/tex]
70 - 32 t = 0
⇒ 70 = 32 t
⇒ [tex]t = \frac{70}{32} = \frac{35}{16}[/tex]
Step(ii):-
The average rate of change in h(t) between t = 1 second and t = 3 second
[tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]
At t = 1
[tex]\frac{dh}{d t} = 70 (1) - 16(2t) = 38[/tex]
At t = 3

If RS is 10, it does not matter where they are. As long as they are 10 units apart, it works.
However, we already know S lies at -12 so we only have 2 choices for R.
Check the picture I uploaded for better understanding.
This is because RS doesn't mean that R has to be before S. It just means that they are a segment. This means that RS and SR are the same segments.

In the diagram, the measure of angle 3 is (23x)°, and the measure of angle 4 is (7x)°. A transversal intersects 2 lines to form 8 angles. Clockwise from the top, the angles are 1, 2, 3, 4; 5, 6, 7, 8. What is the measure of angle 4? 30° 42° 120° 138°
Answer:
the corect option is c
Step-by-step explanation:
The measure of the angle 4 is 42°.
What are linear pair angles?A pair of angles formed on a straight line are said to be a linear pair. The sum of angles of a linear pair is always 180 degrees.
Given that, the measure of angle 3 is (23x)°, and the measure of angle 4 is (7x)°, we need to find the measure of angle 4,
Since, angle 3 and angle 4 are linear pair angles, therefore,
∠3 + ∠4 = 180°
23x + 7x = 180°
30x = 180°
x = 6
Therefore, ∠4 = 7 × 6
∠4 = 42°
Hence, the measure of the angle 4 is 42°.

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 2/7 of
the drink is apple juice and 1/2 is orange juice then write the ratio of cranberry juice to apple
juice to orange juice in its simplest form,
Answer:
3 : 4 : 7
Step-by-step explanation:
apple juice - 2/7 = 4/14
orange juice - 1/2 = 7/14
AJ + OJ = 11/14
this means that 3/14 of the punch is cranberry juice.
cranberry : apple : orange

Answer:
m<C = 42°
Step-by-step explanation:
Given:
m<A = (2x - 2)°
m<C = (4x - 6)°
m<DBC = (5x + 4)°
Thus:
m<DBC = m<A + m<C (exterior angle theorem of a triangle)
(5x + 4)° = (2x - 2)° + (4x - 6)°
Solve for x
5x + 4 = 2x - 2 + 4x - 6
Collect like terms
5x + 4 = 6x - 8
5x - 6x = -4 - 8
-x = -12
Divide both sides by -1
x = 12
✔️m<C = (4x - 6)°
Plug in the value of x
m<C = 4(12) - 6 = 48 - 6
m<C = 42°
Step-by-step explanation:
[tex]\angle{DBC }[/tex]=(5x+4)°
[tex]\angle{ A }[/tex]=(2x-2)°
[tex]\angle{C }[/tex]=(4x-6)°
we know that,
[tex]\angle{DBC}[/tex]=[tex]\angle{A}[/tex]+[tex]\angle{C}[/tex]
According to the question,
[tex]\tt{ 5x+4=2x-2+4x-6 }[/tex]
[tex]\tt{ 5x+4=6x-8 }[/tex]
[tex]\tt{ 6x-5x=4+8 }[/tex]
[tex]\bold{x=12 }[/tex]
so,
[tex]\angle{C }[/tex]=(4x-6)°=(4×12-6)°=(48-6)°=42°
Aimee's garbage disposal has 7/8 horse power. Vincent's garbage disposal has 3/5 horse power. How much more power does aimee's garbage disposal have?
Answer:
Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.
Step-by-step explanation:
Aimee's garbage disposal horse power = 7/8
Vincent's garbage disposal horse power = 3/5
All we need is to subtract Vincent's power from Aimee's power.
i.e.
[tex]\frac{7}{8}-\frac{3}{5}[/tex]
Thus,
[tex]\frac{7}{8}-\frac{3}{5}\:=\frac{35}{40}-\frac{24}{40}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]=\frac{35-24}{40}[/tex]
[tex]=\frac{11}{40}[/tex]
Thus, Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.

Everytime you see per, that usually means "some value times a variable"
2. 17 miles would cost 66. 15(1)+3(17)= 15+ 51= 66.

Invertible functions are functions whose inverse can be calculated.
The values of the expressions are: [tex]f^{-1}(f(5)) = 5[/tex] and [tex]f(f(5)) = 11[/tex]
The table entry is given as:
x | 5 | 3 | 1 | 18 | 0 | 9
f(x) | 9 | -2 | -5 | -1 | 1 | 11
(a) Calculate f^-1(f(5))
Start by calculating f(5).
From the table, we have:
[tex]f(5) = 9[/tex]
Take inverse function of both sides
[tex]f^{-1}(f(5)) = f^{-1}(9)[/tex]
From the table, the inverse value of 9 is 5.
i.e. [tex]f^{-1}(9) = 5[/tex]
So, we have:
[tex]f^{-1}(f(5)) = 5[/tex]
(b) Calculate f(f(5))
In (a) above, as have:
[tex]f(5) = 9[/tex]
So, the function becomes
[tex]f(f(5)) = f(9)[/tex]
From the table, the value of f(9) is 11.
So, we have:
[tex]f(f(5)) = 11[/tex]
