Determine an expression that would represent the area of the figure shown.
5x + 9
3x + 7
A
15x2 + 62x + 63
B
15x2 + 63
с
8x2 + 243 + 16
Answer:
Option A : 15x² + 62x + 63 is the correct answer.
Step-by-step explanation:
Given measurements of the figure are:
5x + 9 and 3x + 7
We have to find the area. We can find the area by multiplying the two expressions.
Area = (5x+9) * (3x+7)
Area = 5x (3x+7) +9(3x+7)
Area = 15x² + 35x + 27x + 63
Area = 15x² + 62x + 63
Hence,
Option A : 15x² + 62x + 63 is the correct answer.

Last year, the tree in Pedro’s front yard was 5 feet tall. This year, the tree is 2 feet less than the height of Pedro’s house. Pedro’s house is 17 feet tall. How tall is the tree?
Answer:
The tree is 15 feet tall.
Step-by-step explanation:
Given that:
Height of tree last year = 5 feet tall
Height of tree this year = Height of Pedro's house - 2 feet
Height of Pedro's house = 17 feet
Height of tree this year = 17 - 2
Height of tree this year = 15 feet
Hence,
The tree is 15 feet tall.

Answer:
FalseFalseFalseFalseStep-by-step explanation:
to understand thisyou need to know about:linear equationPEMDASgiven:y=-4x+13
justify:if
The line has a slope of -13. The line has a slope of 4. The line passes through the point (0, 13). The line passes through the point (0,-4)let's justify:the slope-intercept form of a linear equation is
y=mx+bwhere,m is slope and b is y-intercept
let's justify the first and second statement
the line has a slope of -13The line has a slope of 4.our given equation is
y=-4x+13
where -4 is our slope or m
therefore,
1 and 2 statements are False
let's justify the third and fourth statement
The line passes through the point (0, 13)The line passes through the point (0,-4)our given equation is
y=-4x+13
where,13 is our y-intercept which means the line passes y-intercept when x=0
therefore,
third and fourth statements are False

Answer: I think the answer is B
Step-by-step explanation:
8(x-4) = 8(1-4) = 8-32
2(4x-16) =2(4*1-16) = 8-32
8(x-4) = 8(2-4) = 16-32
2(4x-16) = 2(4*2-16) = 16-32
Answer:
B. Infinitely many solutions.
Step-by-step explanation:
8(x - 4) = 2(4x - 16)
^--This is the original equation.
If we replace x with 1...
we have the same equation, but we add an extra set of brackets. (You'll see why in a second)
8(1 - 4) = 2{4(1) - 16}
1 - 4 = -3
We start by subtracting 4 from 1. When using positive numbers, we can't do this, however. This gets us to -3. leave it in the parenthesis though!
8(-3) = 2{4(1) - 16}
4(1) = 4
Now, the reason we made an extra set of brackets is because 4x is asking you to multiply 4 by x. but as a number, you have to make an extra set of parenthesis to show that. 4 x 1 = 4 so it stays as a 4.
8(-3) = 2(4 - 16)
^-- Now, we are given this new equation. We'll move away from 8(-3) for just a second, to finish the other parenthesis. But still don't remove the parenthesis for 8(-3)!
4 - 16 = -12
We know that 4-16 would also not be possible with positive numbers, but for this equation, as said before.. you're using negative numbers. so 4 - 16 = 12
8(-3) = 2(-12)
^-- And again, we have a new equation. 8(-3) = 2(-12). Don't remove the parenthesis, as I have said before.
8(-3) = -24
Again, the equation shows with parenthesis, it wants us to multiply. Now we take 8, and multiply it by -3. This is a bit tricky, as it is with negative numbers. But in the end, you should have -24.
-24 = 2(-12)
^--The equation becomes -24 = 2(-12). We'll have to multiply again, so keep the parenthesis.
2(-12) = -24
2(-12) Is also asking you to multiply, so now we do the same as before, which again, is a bit tricky because we are using negative numbers. You should end up with -24 though.
-24 = -24
^--Now, you have -24 = -24. This is true since both are the same number.
8(x - 4) = 2(4x - 16)
^-- Here's our wonderful equation again! Let's replace X with a 2 this time!
If you don't understand, read the tips from above to understand what I'm doing in the following equations!
8(2 - 4) = 2{4(2) - 16}
2 - 4 = -2
8(-2) = 2{4(2)-16}
4(2) = 8
8(-2) = 2(8 - 16)
8 - 16 = -8
8(-2) = 2(-8)
8(-2) = -16
-16 = 2(-8)
2(-8) = -16
-16 = -16
And again, we get the same two numbers!

how to solve this one
Answer:
You can use substitution, elimination, or graphing.
Step-by-step explanation:
So what I would do, is using elimination because you have two variables that are the same, what I mean is that you have two -3y's, So, take one equation, lets do the top one, and multiple the whole thing, yes, the WHOLE THING meaning both sides by -1. This will give you -6x+3y= -12. The negative turns to positive because you multiply the -3y by -1. Notice how you have a +3y in the top equation now and a -3y in the bottom one. This is why the method is called elimination, you can cross out the +3y and -3y and combine both equations. You now have -2x=12. Divide both sides by -2, x=-6. Plug -6 in the first equation, you get 6(-6)-3y=12 which goes to -36-3y=12. Add 36 on both sides, you get -3y=48. Divide both sides by -3, you get y=-16. Oh yeh, plug y into one of the equations and solve for x, i forgot to say that.

Answer:
a = 5 seconds and b = 50 inches c = No, because it starts at 50 inches and only goes down after that. This means it will never be at 120 inches.
Step-by-step explanation:
A. Solve it as a quadratic equation where h = 0 (because it will be 0 inches above the water).
0 = - 16t^2 + 70t + 50
0= -2(8t^2 - 35t -25)
0= -2(t - 5)(8t + 5)
Since the amount of time has to be positive, t - 5 = 0, so t = 5 seconds
B. Substitute t = 0 into the equation.
h = -16(0)^2 + 70(0) + 50
h = 0 + 0 + 50
h = 50 inches
C. It's diving, so it's only going down and won't reach 10 feet.

Step-by-step explanation:
x=y+10
1x+1y=64 d
y+10+y=64
2y+10=64
2y=54
y=27
x=37
Answer:
Part A)
[tex]x=10+y\\\\ x+y=64[/tex]
Part B)
There are 37 students in the drama club.
And there are 27 students in the yearbook club.
Step-by-step explanation:
We know that there are 64 students in total in a drama and yearbook club.
The drama club has 10 more students than the yearbook club.
We will let x represent the number of students in the drama club and y represent the number of students in the yearbook club.
Part A)
Since the drama club (x) has 10 more students than however many the yearbook club (y) has, we can write:
[tex]x=10+y\\[/tex]
And since there are in total 64 students, x plus y must equal that sum. So:
[tex]x+y=64[/tex]
Part B)
We can substitute the first equation into the second:
[tex](10+y)+y=64[/tex]
Combine like terms:
[tex]2y+10=64[/tex]
Subtracting 10 from both sides:
[tex]2y=54[/tex]
Dividing by 2:
[tex]y=27[/tex]
So, the amount of students in y or the yearbook club is 27 students.
Since the drama club has 10 more, there are 37 students in the drama club.

Answer:
The constant of proportionality is 28
Step-by-step explanation:
For the constant of proportionality, you'll want to basically find the slope.
The constant of proportionality, k, is defined as:
[tex]k=\frac{y}{x}[/tex]
Thus, we can do this for all three values and reach a conclusion:
[tex]k=\frac{224}{8}[/tex]
[tex]k=\frac{280}{10}[/tex]
[tex]k=\frac{112}{4}[/tex]
In each of these cases, we see that the value of k is 28, therefore, the constant of proportionality is 28
For the second problem, put the cards in their respective places on the number line given.

do a y=mx+b equation
Answer:
y=-2x
Step-by-step explanation:
The y-intercept is 0 so b is 0
and it is going down 2 right 1 so it is -2/1 -2/1 =-2 so it is y= -2x
Answer:
y = -2x + 0
Step-by-step explanation:
y = mx + c
m = gradient and c = y intercept ( the point where the line intercepts the y axis)
Firstly, we can tell the gradient is negative because it has a negative slope (sorta like down a hill) where as x increases y decreases.
To calculate the gradient you use the equation y/x
Pick anywhere on you graph and measure. I have taken from (0,0) to (0,-4) for y and (0,-4) to (2,-4) for x.
Next subtract them (0,-4) - (0,0) = 0,-4. Then take that - 4 for y
Next subtract for them for x (0,-4) - (2,-4) = 0- 2 and -4 -(-4)
= -2 and -4 + 4 = 0
= -2
So y = -4 and x = -2
y/x = 4/2 = 2
Because we know our gradient is negative add a minus and we get our gradient as -2
For y intercept simply find where the line crosses through the y axis, which in this question happens to be 0
answer = -2x + 0
