Answer:
4x^2-9x+3
Step-by-step explanation:
(4x^2 −2x−6)- (7x−9)
=(4x^2-2x-6-7x+9)
=(4x^2-9x+3)
4x^2-9x+3is the answer
Answer:
4x² - 9x + 3
Step-by-step explanation:
(4x² - 2x - 6) - (7x - 9)
4x² - 2x - 6 - 7x + 9
4x² - 2x - 7x - 6 + 9
4x² - 9x + 3

Answer:
(A). [tex]\frac{15}{2}[/tex] + [tex]\frac{33}{4}[/tex] k
Step-by-step explanation:
[tex]\frac{3}{4}[/tex] × 2(2 + 4k + 3 + [tex]\frac{3}{2}[/tex] k ) = [tex]\frac{3}{2}[/tex] ( 5 + [tex]\frac{11}{2}[/tex] k ) = [tex]\frac{15}{2}[/tex] + [tex]\frac{33}{4}[/tex] k
5) 6x + 5y =-15
Need help it’s writing linear equations!!
Answer:
the Slope is -6/5 and y is (0,-3)
Step-by-step explanation:
we need to put this equation in y = mx + b
6x - 5y = -15 u will subtract 6x from both sides
5y = -6x -15...divide both sides by 5
and then simplify
y = -6/5x - 3
and when u graph its will be (0,-3)
ur slope(m) = -6/5 and ur y int (b) = -3

Step-by-step explanation:
2. Follow the process used to simplify the expression. Tell if it was done correctly. If not, explain and correct the error by showing your own work.
2/3 (6k – 9) + 8k – 2
4k - 9 + 8k - 2
12k - 11
Answer:
No, the simplification is not done correctly. When multiplying
[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.
the correct answer is 12k-8
Step-by-step explanation:
We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.
The steps given are:
[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11[/tex]
No, the simplification is not done correctly. When multiplying
[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.
Correcting the error:
[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8[/tex]
So, the correct answer is 12k-8

Find an equation of the circle that has center (-1,6) and passes through (-6,1)
Answer:
(x + 1)² + (y - 6)² = 50
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)
r = [tex]\sqrt{(-6+1)^2+(1-6)^2}[/tex]
= [tex]\sqrt{(-5)^2+(-5)^2}[/tex]
= [tex]\sqrt{25+25}[/tex]
= [tex]\sqrt{50}[/tex]
(h, k ) = (- 1, 6 ), then
(x - (- 1))² + (y - 6)² = ([tex]\sqrt{50}[/tex] )² , that is
(x + 1)² + (y - 6)² = 50 ← equation of circle

Step-by-step explanation:
Brenda has two remote-controlled race cars painted blue and red, respectively.The blue car traveled 54 feet 4 secounds.The red car traveled 38 feet im 2 seconds.
Answer:
The red car is faster compared to the blue car.
The red car is faster by 5.5 feet than the blue car.
Step-by-step explanation:
The objective is to find which car is faster and by how much
Given that:
The blue car traveled 54 feet in 4 seconds; &
The red car traveled 38 feet in 2 seconds.
Let us determine the number of feet traveled in each second for both cases.
For the blue car:
In 1 second, the car will travel = 54/4 feet
In 1 second, the car will travel = 13.5 feet
For the red car:
In 1 second, the car will travel = 38/2 feet
In 1 second, the car will travel = 19 feet
Thus, the red car is faster compared to the blue car.
The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet
= 5.5 feet
A car was bought for $20 000 in January 2017. If the car depreciates by 10% every year, what was it worth in January 2020?
A) $2 000
B) $1 800
C) $18 000
D) $14 580
Answer:
D
Step-by-step explanation:
20,000-10%-10%-10%
is
20000-2000-1800-180
which is 20000-5980
which is 14580
which is D
Hope this helps ;D
Answer:
The answer is D) $14,580
Step-by-step explanation:
If its losing 10% each year that means the first drop would be to $18000, then the next to 16200, then the last is 14580.

Answer:
A. x = 6
Step-by-step explanation:
a^2 + b^2 = c^2
8^2 + b^2 = 10^2
64 + b^2 = 100
b^2 = 100 - 64
b^2 = 36
√b^2 = √36
b = 6
Carlos says that if the numerators of two fractions are the same, you can compare the denominators to determine which
one is greater. Which statement best describes Carlos's idea?
Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.
Carlos is correct. If the numerators are the same, the fraction with the greater denominator will be greater.
Carlos is incorrect. If the numerators are the same, the fractions will be equal.
Carlos is incorrect. You cannot compare fractions using only the denominators even if the numerators are equal.
Answer:
Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.
Step-by-step explanation:
I'll answer this question using the following illustration.
Let a fraction be:
[tex]\frac{1}{2}[/tex]
and another fraction
[tex]\frac{1}{4}[/tex]
Both numerators are 1. In other words, they are equal
When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater
This is so because:
[tex]\frac{1}{2} = 0.5[/tex]
[tex]\frac{1}{4} = 0.25[/tex]
By comparison
[tex]0.5 > 0.25[/tex]
This analysis can be used for any fraction as long as they have the same numerator
Hence, option A answers the question

A
