need help
Answer:
The y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.
Step-by-step explanation:
Given the function
[tex]y=3x+2[/tex]
the y-intercept of the function can be determined by setting x=0 and solving for y.
so
[tex]y=3x+2[/tex]
[tex]y=3(0)+2[/tex]
[tex]y=0+2[/tex]
[tex]y=2[/tex]
Thus, the y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.

Which of the binomials below is a factor of this trinomial?
x2 + 13x + 42
A. x - 7
B. x + 7
C. x + 84
D. x2 + 12
Answer:
B.
Step-by-step explanation:
To factor trinomials, you need two numbers that multiply together to give you the third term and add together to give you the second term.
What are two factors that multiply to get 42 and add to get 13? These factors are 6 and 7.
Write the factorization as such:
(x+7)(x+6)
(x+7) is choice B.
Answer: x-7

Ella earns some extra christmas shopping money baby elf-sitting but after stocking up on wrapping paper she only has a third of her earnings left.She also spent $12 on a stylish new santa hat.What were her elf-sitting earnings if she only has $20 left?
Answer:
96 dollars.
Step-by-step explanation:
Given that Ella earns some extra christmas shopping money baby elf-sitting but after stocking up on wrapping paper she only has a third of her earnings left.
Let Ella earnings = E
Third of her earning left = E/3
She also spent $12 on a stylish new santa hat.
That is, E/3 - 12
What were her elf-sitting earnings if she only has $20 left?
Then,
E/3 - 12 = 20
Collect the like terms
E/3 = 20 + 12
E/3 = 32
Cross multiply
E = 32 × 3
E = 96 dollars
Therefore, her elf-sitting earnings is 96 dollars.

2) { x+y+z=5
{ 2x-3y+z=7
{ x+2y-4z=2
3) infinity many solutions
4) use equations (1) and (2) to eliminate y

The number 312 lies between the perfect cubes
Answer:
The number 312 lies between the perfect cubes 216 and 343.
So the cube root of 312 lies between the number 6 and 7.
This means that the cube root of 312 is an irrational number because it is not a perfect cube root.

1. Edna leaves the entrance to the trail at dawn to hike 12 miles toward the lake, where her friend Maria is
campling. At the same time, Maria starts her hike toward the trail entrance to meet Edna. Edna is walking
at 1.5 mi/h, while Maria averages 2.5 mi/h. When and where will they meet?
Answer:
(3,4.5)
Step-by-step explanation:
y=0+1.5x
y=12-2.5x
0+1.5x = 12 - 2.5x
First you replace y with the first equation to make a new equation of 0+1.5x = 12 - 2.5x. And then after that you will cancel out 2.5 with adding and then add 2.5 to 1.5. After you add them you get 4 and then divide to get x by itself 4/4 12/4 You get x=3 And then you will solve by replacing canceling out and replacing x with 3 to get 4.5.
Greg invested $11,000 in two accounts.
• The first account pays 5% interest per year.
• The second account pays 8% interest per year.
• Greg earned a total of $752.50 in interest at the end of the first year.
How much did Greg invest in the 5% account?
A. $6,750
B. $3,415
C. $5,500
D. $4,250
Answer:
The amount invested in the 5% account is $4,250
Step-by-step explanation:
Let the amount invested in the first be $x and the amount invested in the second be $y
Total of both is $11,000
Thus, we have
x + y = 11,000 •••••••••(i)
For the first account, the interest earned will be;
5/100 * x = 5x/100 = 0.05x
For the second account , the interest earned will be;
8/100 * x = 0.08x
Adding both gives the total amount of interest
That will be ;
0.05x + 0.08y = 752.50 •••••(ii)
From equation i above;
y = 11,000 - x
Substitute this into ii
0.05x + 0.08(11,000-x) = 752.5
0.05x + 880 - 0.08x = 752.5
0.08x-0.05x = 880-752.5
0.03x = 127.5
x = 127.5/0.03
x = $4,250
HELP ASAP THIS IS GEOMETRY
Answer:
x=48
y=70
step by step explanation:
In the question,
Since the triangle two sides of the traingle is equal, it is an isosceles triangle.
For an isosceles triangle, angles opposite to equal sides are equal,
Hence,
[tex](x + 7) = 55[/tex]
[tex]x = 55 - 7[/tex]
[tex]x = 48[/tex]
[tex]y = 180 - (55 + 55)[/tex]
[tex]y = 180- 110[/tex]
[tex]y = 70[/tex]

Answer:
The gram and kilogram are two units used to measure mass in the metric system . From the gram, we get the rest of the metric units using the standard metric prefixes. A paper clip has a mass of about 1 gram. A 1 liter bottle of water has a mass of 1 kilogram (plus a little bit extra for the plastic).

Answer:
5 to the 15th power.
Step-by-step explanation:
PEMDAS requires us to do parenthesis, then exponents, and then division. Let's do 5³. 5x5x5 is equal to 125. Now, we find 125 to the ninth power. According to my calculations, 125 to the ninth power is equal to 7,450,580,596,923,828,125. Now, we find 5 to the twelfth power, which, according to my calculations, is 244,140,625. Now, we solve. According to my calculations, 7,450,580,596,923,828,125/244,140,625 is equal to 30,517,578,125. 30,517,578,125 is equivalent to 5 to the 15th power. That means that the second option is correct. I hope this helps!

Vhich point-slope equation represents a line that passes through (3,-2) with a slope of -4/5 ?
Answer:
y = -4/5x + 2/5
Step-by-step explanation:
Slope form of an equation is y = mx + b
Sub in x and y coordinates and slope then isolate for b
-2 = -4/5(3) + b
-2 = -12/5 + b
-2 + 12/5 = b
b = -10/5 + 12/5
b = 2/5
Sub in b and the slope into the slope form equation
y = (-4/5)x + 2/5
