Factor the following: 7k^2+3k-10
Step-by-step explanation:
7k² + 3k - 10
= 7k² + ( 10 - 7 ) k - 10
= 7k² + 10k - 7k - 10
= k( 7k + 10 ) - 1( 7k + 10)
= ( 7k + 10) ( k - 1)
Hope it will help :)
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem to determine the roots
k = 1,-10/7
7k^2+3k-10 = 7(k-1)(k+10/7) = (k-1)(7k+10)
Sole the equation x^2=16
Answer:
4
Step-by-step explanation:
4^2 = 4x4 = 16
Answer:
x = ± 4
Step-by-step explanation:
Given
x² = 16 ( take the square root of both sides )
x = ± [tex]\sqrt{16}[/tex] = ± 4
That is x = - 4, x = 4

what are the x and y intercepts for this equation y=−1/4x+2?
(_,_)
Answer:
(8, 0) is the x-intercept
(0, 2) is the y-intercept
Step-by-step explanation:
The y-intercept = 2 since the equation is in slope-intercept form.
The x-intercept occurs when y = 0
So, 0 = -1/4x + 2
0 = -x + 8
x = 8
(8, 0) is the x-intercept
(0, 2) is the y-intercept
Last year 80 students signed up for a summer trip to Washington, D.C. This summer 50 students have signed up to go. What is the percent decrease in the number of students?
A 30%
B 37.5%
C 60%
D 62.5%
i will mark brainliest
Given:
Last year 80 students signed up for a summer trip to Washington, D.C.
This summer 50 students have signed up to go.
To find:
The percent decrease in the number of students.
Solution:
We have,
Students in last year = 80
Students in this year = 50
Now,
[tex]\text{Decrease}\%=\dfrac{\text{Students in last year - Students in this year }}{\text{Students in last year }}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{80-50}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{30}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{3}{8}\times 100[/tex]
[tex]\text{Decrease}\%=37.5[/tex]
Therefore, the correct option is B.

Step-by-step explanation:
In a lab, 700 cells are present at the beginning of an experiment. During the first 7 hours,
the number of cells increased by 12% each hour.
Estimate the time when the number of cells is 1735.
Round answer to nearest whole hour.
Answer:
2 hours
Step-by-step explanation:
1=700
x=1735
1735=700x
1735/700
x=2.47
Answer:
Step-by-step explanation:
This is an exponential equation of the form, A=ar^t, where a is the initial amount and r is the common ratio or rate of growth and t is time. In this case.
A=700(1.12)^t and we want to find when A=1735
1735=700(1.12)^t
1735/700=1.12^t
ln(1735/700)=t(ln(1.12))
t=(ln(1735/700))/(ln(1.12))
t=8 hours

A rectangular garden has an area of 60 squared feet. The garden is 4 feet longer than it is wide. Which equation can be used to determine the length and width of the garden?
Answer: See explanation
Step-by-step explanation:
Let the width be x
Then, the length will be x+4
Area = Length × Width
Therefore,
x × (x+4) = 60
x² + 4x = 60
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0
x = 6
The width is 6feet
Length = 6+4 = 10 feet
