Answer:
[tex]y=24,[/tex] when [tex]x=1[/tex].
Step-by-step explanation:
Given: [tex]y=4x+20[/tex]
To find: Value of [tex]y[/tex], substituting the known value of [tex]x[/tex]
We have,
[tex]y=4x+20 ...(i)[/tex]
Putting [tex]x=1[/tex] in equation [tex](i)[/tex], we get
[tex]y=4(1)+20[/tex]
[tex]\implies y=4+20[/tex]
[tex]\implies y=24[/tex]
Hence, the value of [tex]y[/tex] is [tex]24[/tex], when the value of [tex]x[/tex] is [tex]1[/tex].
In the diagram below, RS and ST are perpendicular.
Which equation represents ST ?
А.
-x+ 3y = 9
В.
3x + y = 13
C
-3x+y=-13
D
3x + y=23
Answer:
A==−x+3y=9
Step 1: Add -3y to both sides.
−x+3y+−3y=9+−3y
−x=−3y+9
Step 2: Divide both sides by -1.
−x
−1
=
−3y+9
−1
x=3y−9
Answer:
x=3y−9

Candice is deep-sea diving with two friends. Whitney is exploring a coral reef 56 feet in front of Candice, and Ed is floating on the surface directly above Candice. If Ed and Whitney are 70 feet apart, how far apart are Candice and Ed?
Answer:
126
Step-by-step explanation:
70
+ 56
126
If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that the Candice is deep-sea diving with two friends
Whitney is exploring a coral reef 56 feet in front of Candice
The distance between Whitney and Candice is 56 feet.
Ed is floating on the surface directly above Candice.
Ed and Whitney are 70 feet apart, we need to find the distance between Ed and candice.
By using Pythagoras theorem we can find this.
70²=56²+x²
4900=3136+x²
Subtract 3136 from both sides
4900-3136=x²
x²=1764
Take square root on both sides
x=42
Hence, If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.

A number c minus 6 is less than or equal to 5.3. Write this word sentence as an inequality.
An inequality is
Answer:
C - 6 < = 5.3
Step-by-step explanation:
Writing the above as an equality, we would have ;
Since C is less than 6, then;
C - 6
Therefore, C minus 6 is less than or equal to 5.3 is
C - 6 < = 5.3
An inequality is when an unequal relationship exist between two expressions, which uses signs such as not equal to , less than < , greater than > etc.

If f(x) = -x2 – 1, and
g(x) = x + 5, then
g(f(x)) = [? ]x? +[ ]x +[ ]
could someone help me with this please, thank u
Answer:
g(f(x)) = -x^2 + 4
Step-by-step explanation:
What we simply have to do here is to put f(x) into g(x)
What this mean is that every x in g(x) will be represented by f(x)
Thus, we have it that
-x^2 - 1 + 5
= -x^2 + 4
If the maximum value of y=-3x² + mx + 10 is 37, find the values of m.
Step-by-step explanation:
y = -3x² + mx + 10
dy/dx = -6x + m.
When dy/dx = 0, -6x + m = 0. => x = m/6.
We have y = -3(m/6)² + m(m/6) + 10 = 37.
=> -m²/12 + m²/6 = 27
=> -m² + 2m² = 324
=> m² = 324
=> m = 18 or m = -18.

5 pencils cost £4.25.
How much do 9 pencils cost?
Answer:
£ 7.65
Step-by-step explanation:
Cost of 5 pencils = £ 4.25
Cost of 1 pencil = £ 4.25 / 5 = £ 0.85
Now
Cost of 9 pencils = £ 0.85 * 9 = £ 7.65
Hope it will help :)❤
Step-by-step explanation:
Hey there!
Given;
The cost of 5 pencils is £ 4.25.
Cost of 9 pencils= ?
Now;
~ Finding cost of one pencil.
Cost of 1 pencil= £4.25/5
= £0.85
~ Finding cost of 9 pencils.
Cost of 9 pencils= £9*0.85
= £7.65
Therefore, the Cost of 9 pencils is £7.65.

Answer: 3234 cubic units
Step-by-step explanation:
Volume of cylinder: πr²h
The diameter of the cylinder is 14 units so the radius is 7 units.
Now we'll substitute.
π = 22/7
h = 21
πr²h
π × 7² × 21
22/7 × 49 × 21 = 3,234
The volume is 3,234 cubic units.

Answer:
b) true for one value
Explanation:
If you solve for x, there is only one value of x
Answer:
(b)
Step-by-step explanation:
9(x - 2) = 7x + 5 ← distribute left side
9x - 18 = 7x + 5 ( subtract 7x from both sides )
2x - 18 = 5 ( add 18 to both sides )
2x = 23 ( divide both sides by 2 )

An arithmetic sequence has this explicit formula: an = 14 + (n - 1)3. What is the recursive formula?
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 with a₁ = 14
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference, then
[tex]a_{n}[/tex] = 14 + (n - 1)3
has a₁ = 14 and d = 3
A recursive formula allows a term in the sequence to be found by adding d to the previous term, thus recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 , with a₁ = 14

Jerry lives 3 1/2 miles away from Jake. Jerry and Jake decided to meet half between their houses and then walk to the park together. The park is located 3/5 mile from the halfway point. How far did Jerry walk in all to get to the park?
Answer: Jerry walked 2 7/20 miles to get to the park
Step-by-step explanation:
1/2 of 3 1/2
1/2 of 7/2 = 7/4
7/4 + 3/5
Find the LCM of the denominator
LCM of 4 and 5 = 20
35/20 + 12/20 = 47/20 = 2 7/20
Jerry walked 2 7/20 miles to get to the park
