PLEASE HELP
Answer:
15p + 3
Step-by-step explanation:
Multiply 3 by each number in the parentheses and keep the variable
Using the distribution property 3(5p + 1) is 15p + 3.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 3(5p + 1).
= 3×5p + 3×1.

Answer:
[tex] \huge \colorbox{red}{y = x + 3}[/tex]Step-by-step explanation:
to understand thisyou need to know about:linear equationPEMDASgiven:b=3let's solve:linear equation slope intercept form:
[tex]y = mx + b[/tex]m is 1 in this question
therefore
substitute the value of m and b
y=x+3Answer:
y = x + 3
Step-by-step explanation:
The given graph indicates that the y-intercept of this line is 3 (that is, b = 3). The y-intercept is also represented by (0, 3). The graph also goes through (-3, 0). The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3. Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.
The slope-intercept equation y = mx + b is therefore y = x + 3.
I would suggest you write out your objective before attempting problem solution. In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?
Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.
Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Answer:
318 days or 10.6 months,
No, because the time between august and december is 8 months and it would take 10 to complete the tunnel
Step-by-step explanation:
start by determining the slope:
subtract the remaining distance from the total distance to determine distance so far, then divide by time.
m = (3200 - 1700)/5
m = 1500/5
m = 300
y = mx + b
Plug in to solve for x.
3200 = 300x + 0
3200 = 300x
divide y by m. This is x. (this is known as inverse operation if you didnt know already.)
3200 = 300(10.6_)

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answer:
The scale factor from triangle PQR to P'Q'R' is 1/4.
The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.
If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).
No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?
Answer:
1/6 of a chance aka 16.666?%
Step-by-step explanation:
The probability of drawing a card with number 7 is 0.166.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
From the given set of cards,
Total number of cards =6
Number of spades = 3
Number of card with number 7 on it = 1
Probability of drawing a 7 = 1/6
= 0.166
Therefore, the probability of drawing a card with number 7 is 0.166.

2. 200.52 4. 212.67 5. 148.48
Step-by-step explanation:
for (2) you find the area of each shape first the square
12*12=144
then you find the area of the semicircle
the formula is A= (3.14)r^2/2
the (r) is 6 because that is half of the whole side of the semicircle
so... (3.14) 6^2/2
6*6= 36
(3.14)36/2
113.04/2
56.52
then add the 144 from the square to it
56.52+144
200.52
