Factor: 10x^3-35x^2-12x+42
I'll give brainliest :) but please show all work.
Answer:
[tex]\left(2x-7\right)\left(5x^2-6\right)[/tex]
Explanation:
[tex]\hookrightarrow\sf 10x^3-35x^2-12x+42[/tex]
using associative property, separate
[tex]\hookrightarrow\sf \left(10x^3-35x^2\right)+\left(-12x+42\right)[/tex]
take common term, factorise
[tex]\hookrightarrow\sf 5x^2\left(2x-7\right)-6\left(2x-7\right)[/tex]
final answer
[tex]\hookrightarrow\sf \left(2x-7\right)\left(5x^2-6\right)[/tex]
Answer:
[tex](5x^2-6)(2x-7)[/tex]
Step-by-step explanation:
[tex]10x^3-35x^2-12x+42[/tex]
Rewrite:
[tex]\implies (10x^3-35x^2)-(12x-42)[/tex]
Factor parentheses:
[tex]\implies 5x^2(2x-7)-6(2x-7)[/tex]
Factor out common term [tex]2x-7[/tex]:
[tex]\implies (5x^2-6)(2x-7)[/tex]
Jenny has $2525 and she earns $1010 for each lawn that she mows. Jenny wants to buy a concert ticket that costs $6565. Enter the minimum number of lawns Jenny needs to mow to be able to buy the concert ticket.
Answer:
6565 = 1010(4) + 2525
Step-by-step explanation:
so the equation would be
6565 = 1010x + 2525
x = 4 because
1010 (4) = 4040
and 4040 + 2525 = 6565, so
6565 = 1010(4) + 2525
A car factory takes 6 hours to produce 60 cars. How many hours does the factory take to produce 300 cars?
Answer:
30 hours
Step-by-step explanation:
Ok, since it can make 60 cars in 6 hours we take the 300 divided by the 60 to get 5. Then, multiply the 5 by the 6 to get 30 hours.
.Answer:
The answer is 30 hours
Step-by-step explanation
60 x 5 = 300 cars produced
6 x 5= 30 hours it takes to produce 300 cars

You are given a line that has a slope of 4 and passes through the point (3/8, 1/2). Which statements about the equation of the line are true? Check all that apply.
The y-intercept is -1.
The slope-intercept equation is y = 4x - 1.
The point-slope equation is y - 3/8 = 4(x - 1/2).
The Point (3/8, 1/2) corresponds to (x1, y1) in the point-slope form of the equation.
Step-by-step explanation:
the point-slope form is
y - y1 = a(x - x1)
with "a" being the slope, (x1, y1) being a point on the line.
so, we have here
y - 1/2 = 4(x - 3/8)
simplifying this gives us then the slope-intercept form
y = ax + b
with b being the y-intercept.
so, we get
y - 1/2 = 4x - 4×3/8 = 4x - 3/2
y = 4x - 3/2 + 1/2 = 4x - 2/2 = 4x - 1
so,
the first, second and forth statements are true, the third is false.
Write an equation in slope-intercept form that contains the points (0,-5), (1,-3), and (2,-1).
Answer:
y=1/2x-5
Step-by-step explanation:
Okay so first we do y2 - y1
-1 - (-3)
a negative minus a negative is just adding so its actually
-1 + 3 = 2
now we do x2 - x1
2 - 1 = 1
The slope is 1/2
If you look at the (0, -5) since x is a y the -5 is our y intercept
now we can make the equation
y=1/2x-5

What is the area of the trapezoid?
6.5 square units
39 square units
40 square units
78 square units
Answer:
39 square units
Step-by-step explanation:
separate the trapezoid into a rectangle and a triangle solve the area for the rectangle which is 30 square units and then solve the area for the triangle so the bottom of the triangle is 3 squares and then the side of it is 6 squares multiply 3 by 6 and then you'll get 18 since that's a triangle you have to divide by 2 and you'll get nine you add 30 and 9 to get 39 square units

What is the height of the tree?
57°
30 feet
Answer:
46.2 feet
Step-by-step explanation:
In the right triangle model, you are given the angle, the adjacent side, and you want to find the opposite side. The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(57°) = height/(30 ft)
Multiplying by the denominator gives ...
height = (30 ft)tan(57°) ≈ 46.2 ft
The height of the tree is about 46.2 feet.
Are the ratios3:6 and 6:3 equivalent? Why or why not?
Answer:
No, they are not equivelent.
Step-by-step explanation:
If we solve both of them :
3:6 = 3/6
3/6 = 1/2
1/2 = 1:2
6:3 = 6/3
6/3 = 2/1 (just 2!)
2/1 = 2:1
So, they aren't the same because they aren't the same fraction and they don't simplify to the same answer :)

Solve the following equation, identifying the domain restrictions, and checking your answers. Must show check for each solution
Answer: 4, 5
Step-by-step explanation:
The domain restrictions are [tex]x \neq 1[/tex] and [tex]x \neq -3[/tex] since those are the values of x for which the denominators equal 0.
To solve, we can start by cross multiplying:
[tex](x+3)(x+2)=7(2x-2)\\x^{2}+5x+6=14x-14\\x^{2}-9x+20=0\\(x-4)(x-5)=0\\x=4, 5[/tex]

Answer:
2p - 4
Step-by-step explanation:
Hello!
Let's start by deciphering what the wording is saying.
So we see he reads 4 less than 2 times the number of pages he read yesterday.
Note the words I put in bold. They're in bold because they signal our operations.
Note the fragment I underlined. It is underlined because that underlined portion refers to our variable, p.
So the amount of pages read is 4 less than 2 times p.
Well, 2 times p is 2p, and 4 less than 2p is 2p - 4
Let me know if you have any questions.

Convert 90 min = ? hrs
Answer:
Conversion:
60 minutes in an hour.
So we already have an hour here so 90-60 = 30
30 minutes is half an hour.
So 90 minutes is 1.5 hours

Which line is the graph of y = 1/2 x + 2?
line a

line d
line b
Answer:
the answer is line A
Step-by-step explanation:
:3 why do i have to write at least 20 characters :/
but Hope its correct
Answer:
Line A
Step-by-step explanation:
By graphing the equation y = 1/2x + 2 you will see that the line intersects at 2. Hence + 2, while all of the other given lines do not intersect at 2.
To further prove the answer, you could also see that line A intersects at -4 when you graph the equation y = 1/2x + 2 you can also see that the line intersects at -4 on the x axis and 2 on the y axis.
Your answer is the first option or "line A."
Hope this helps.

Write an equation to describe the sequence below. Use n to represent the position of a term
in the sequence, where n = 1 for the first term.
4, 8, 16, ..
Answer:
[tex]4(2)^{n-1}[/tex]
Step-by-step explanation:
this is a geometric sequence and to get each next number you multiply by two so [tex]a(b)^{n-1}[/tex] becomes put 2 in for b and you get [tex]a(2)^{n-1}[/tex].You can put 4 in for a because its the first number of the sequence. [tex]4(2)^{n-1}[/tex]
