Answer:
y = 4x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
16x - 4y = - 20 ( subtract 16x from both sides )
- 4y = - 16x - 20 ( divide terms by - 4 )
y = 4x + 5 ← in slope- intercept form
The equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction.
The slope of a straight line between two points says [tex](x_1,y_1),(x_2,y_2)[/tex] and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘[tex]m[/tex]’.
As we know that, the equation of a line in slope- intercept form is
[tex]y = mx + c[/tex]
where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.
So,
[tex]16x - 4y = - 20\\\\-4y=-20-16x\\\\-4y=-(16x+20)\\\\4y=16x+20\\\\y=\frac{16x}{4}+\frac{20}{4}\\\\y=4x+5[/tex]
Hence, the equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].

A sculptor plans to ship the pyramid shown in one of three boxes. The interior of the pyramid holds 4,500 cm3 of water. The base is an isosceles trapezoid. Into which boxes will the pyramid fit? Drag “yes” or “no” to each box height.
Answer:
28 cm and 32 cmStep-by-step explanation:
Volume of the pyramid:
V = 1/3BhFind base area:
B = 1/2(20 + 30)*20 = 500 cm²Substitute value of the volume and find the height of the pyramid:
4500 = 1/3*500*hh = 4500*3/500h = 27 cmThe boxes with h > 27 can fit the pyramid:

if you’re standing on the street 1,300 feet from the bottom of the building, you have to look up at a 23 degree angle to see the top. How tall is the building ? explain or show your reasoning.
Answer:
551.82feet tall
Step-by-step explanation:
WE are given the following from the question;
Distance of me from the bottom of the building = 1300feet (adjacent)
Angle of elevation = 23 degrees
Required
Height (opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 23 = H/1300
H = 1300tan23
H = 1300(0.4245)
H = 551.82feet
Hence the building is 551.82feet tall

Answer:
The first graph
Step-by-step explanation:
The function shows a 4x-2 relationship so to test if the relationship works you multiply a number by 4 and subtract 2, if it follows this then it represents h but if it doesn't then it is incorrect. The first graph is the only answer choice that follows this function so it is the correct answer.
What is the value of log4 2?
Answer:
1/2
Step-by-step explanation:
type it into the calculator
The value of logarithm log base 4(2 is 1/2.
What is Logarithm?The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b.
Given:
Rewrite as an equation.
log base 4(2)=x
and, Rewrite log base 4(2)=x in exponential form using the definition of a logarithm. If x and b are positive real then
log (base b) x= y equivalent to [tex]b^y[/tex] = x
Create expressions in the equation that all have equal bases.
log base 4(2)=x
[tex](2^2)^x[/tex] = 2
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
2x = 1
x= 1/2.

Kevin has at most $30 to spend at the fair. The entrance fee is $5.50 and each activity is $1.25.
Write the equation that represents the problem.
Given:
Entrance fee = $5.50
Additional fee = $1.25 for each activity.
Total amount spend at fair = $30
To find:
The equation that represents the problem.
Solution:
Let the number of activities be [tex]x[/tex].
Additional fee for 1 activity = [tex]\$1.25[/tex]
Additional fee for x activity = [tex]\$1.25x[/tex]
Total fee = Entrance fee + Additional fee for x activity
= [tex]\$5.50 + \$1.25x[/tex]
It is given that Kevin has at most $30 to spend at the fair. So, total fee must be equal to $30.
[tex]\$5.50 + \$1.25x=\$30[/tex]
[tex]5.50+1.25x=30[/tex]
Therefore, the require equation is [tex]5.50+1.25x=30[/tex].
Note: The inequality for the given problem is [tex]5.50+1.25x\leq 30[/tex].

Benson spent 5/6 of an hour reading on each of three days this week. How long did Benson spent reading this week?
Answer: You want to know how many hours he was reading per week. 5/6 * 3 = 15/6 Hours = 5/2 Hours = 2 Hours 30 minutes.
150 minutes
Step-by-step explanation:
5/6 = 50/60. 60 min in an hour. so 5/6 would mean 50 min of 60. he spent 50 minutes each day reading. now since it says 3 days, youd multiply that by 3. ultimately, youd get 150 min in total.
