Nora and Eli are making homemade spring rolls for a party. Nora can make 8 spring rolls in 10 minutes. Eli can make 10 spring rolls in 12 minutes. If they each make 40 spring rolls, who will finish first?
Answer: Eli
Explanation: Nora will make 40 spring rolls in 50 minutes and Eli will make 40 spring rolls in 48 minutes so Eli is faster.
Which of the following answers is the best description for the deer population with the greatest growth rate: A.The blue line shows a deer population that grew with an exponential growth rate. In the first year the population increased by only one deer, but between years seven and eight the population grew by two deer, showing that the growth rate continuously doubles. B.The blue line shows a deer population that grew with a linear growth rate, because the graph shows that the population increased by approximately one deer per year. C. The red line shows a linear growth rate, because an approximate straight line estimates a growth rate of five deer per year. D. The red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing
Answer: D) the red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing.

I think x is 122
y is 58
z is 122
Did I mess it up? Can I get checked?
Answer:
You are correct!
Step-by-step explanation:
Hi!
You are right! If y is in the same spot as 58 degrees, then y is 58 degrees as well! Same goes for x. If z is 122 degrees, then x must be 122 degrees! Great job figuring this one out!
If you like my answer, please rate it! I'd also appreicate a Thanks!
Have a great day!
Find the gradient of the straight line joining A(-4, -1) to B(4, 2)
Answer:
The slope of the line is [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
Given parameters:
A(-4, -1) to B(4, 2)
Unknown:
The slope of the line joining the two points
Solution:
To find the slope of the line; we use the expression below:
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]
x₁ = -4
y₁ = -1
x₂ = 4
y₂ = 2
Input the parameters and solve;
Slope = [tex]\frac{2 -(-1)}{4-(-4)}[/tex]
Slope = [tex]\frac{3}{8}[/tex]
The slope of the line is [tex]\frac{3}{8}[/tex]
3(y – 5) + 2 = 5
A. y = 4
B. y = 7
C. y = –4
D. y = 6
Answer:
y = 6
Step-by-step explanation:
Step 1: Write equation
3(y - 5) + 2 = 5
Step 2: Solve for y
Distribute 3: 3y - 15 + 2 = 5Combine like terms: 3y - 13 = 5Add 13 to both sides: 3y = 18Divide both sides by 3: y = 6Step 3: Check
Plug in y to verify it's a solution.
3(6 - 5) + 2 = 5
3(1) + 2 = 5
3 + 2 = 5
5 = 5

Answer:
x = 57.59
Step-by-step explanation:
979 * 1 / 17
x = 57.59
cross multiply then divide.
if you want to be thorough and make the equation
17x = 979(1)
x = 57.59
Write the equation in standard form using integers.
Y=2x+5
Answer: x = - 5/2 five is on top and 2 is bottom

the system ax-by=-16 and ax+2y=20 has one solution at the point (3,4). Find a and b. (a=4,b=7)
Answer:
Step-by-step explanation:
substitute (3,4) to equation: ax+2y=20
3a+8=20
a=4
Then, 4x-by=-16
substitute (3,4) to solve b,
4*3-b(4)=-16
b=7
Which is an equation of the line that is parallel to y = 2x - 2 and passes
through the point (7, 8)?

B) 2x + y = 22
C) 2x - y = 2
D) 2x - y = 6
Answer:
Option D ( 2x-y = 6 )
Step-by-step explanation:
They have the same gradient and when x,y values are substituted in this equation, they are equal.

calculate the areas of these rectangles
A(a) = 24 cm²
A(b) = 40.04 cm² ≈ 40 cm²
Step-by-step explanation:Hi there !
area formula (rectangle)
A = l × w
A(a) = 8cm × 3cm = 24 cm
A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²
Good luck !
At 2:00 AM in Alaska, the temperature was -1°F. The temperature dropped 3 degrees each hour after that. What
was the temperature 3 hours later?
A -8°F
B
-23 F
C -4°F
D-124 F
Answer:
-10* F
Step-by-step explanation:
What confuses me is that the answers you have provided aren't correct, when I made a number line starting at 0 and ending at -23* F and I had counted three degrees for each hour I got -10* F.
2am 3am 4am 5am
0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16 -17 -18 -19 -20 -21 -22 -23
2am is at -1* F, 3am is at -4* F, 4am is at -7* F, and 5am is at -10* F.
This is over the course of three hours after 2am so unless I got this wrong you might want to ask your teacher.
Answer: -10 degrees
None of those 4 choices are correct

what is the equation of a like that goes through the point 5,-2 and has a slope of. 6/5
Answer:
y= 6/5x -8
Step-by-step explanation:
The slope-intercept form (basically the form for the equation of a line)
y=mx+b
m is the slope
x is the value you want to plug in, or the x term in a point (x, y)
we know so far,
y=6/5x + b
so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope
-2 = 6/5(5) + b
6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6
so
-2 = 6 + b
subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)
-8 = b
