-(5x –4) = 49 a.x = -9 b.x = -8 c.x = 9 d.x = 8 HELPPPPPPPP
Answer:
x = - 9
Step-by-step explanation:
Given
- (5x - 4) = 49 ← distribute the parenthesis by - 1
- 5x + 4 = 49 ( subtract 4 from both sides )
- 5x = 45 ( divide both sides by - 5 )
x = - 9

6(3x+4)-4(2x-6)-8x
explain step by step
Answer:
The answer is 2x+48
Step-by-step explanation:
1: Distribute
6(3x+4)-4(2x-6)-8x
18x + 24 - 4(2x-6)-8x
2: Distribute
18x + 24 - 4(2x-6)-8x
18x + 24 - 8x + 24 - 8x
3: Add the numbers
18x + 24 - 8x + 24 - 8x
18x + 48 - 8x - 8x
4: Combine like terms
18x + 48 - 8x - 8x
2x+48
Solution:
2x+48

The curve with equation y = x^2 + ax + 3 has a stationary point when x = 4. Find a.
Answer:
Step-by-step explanation:
y=x^2+ax+3
y=(4)^2+a(4)+3
y=16+4a+3
y=19+4a
y-19=4a
y-19/4=a
a=y-4.75
f(x)=-x²-2x-8 determine the vertex
Answer:
vertex = (- 1, - 7 )
Step-by-step explanation:
Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² - 2x - 8 ← is in standard form
with a = - 1 and b = - 2, then
[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7
vertex = (- 1, - 7 )

The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.
Answer:
The percent decrease in the price of shirt is 27.78%
Step-by-step explanation:
The percent decrease is the decrease in the price of a product or good.
Given
Original Price = $45
Decreased price = $32.50
Percentage decrease is calculated by using the formula
[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]
And the decrease is calculated as:
[tex]Decrease = Original\ price - Reduced\ price[/tex]
So,
[tex]Decrease = 45-32.50 = 12.5[/tex]
Putting the values in the formula for percent decrease
[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]
Rounding off to nearest hundredth: 27.78%
Hence
The percent decrease in the price of shirt is 27.78%
the simple interest on a certain sum of money for 2(1/2) years at 12% per annum is Rs.40
Step-by-step explanation:
[tex] si = p \times \frac{r}{100} \times t[/tex]
[tex]si = 40 \times \frac{12}{100} \times \frac{5}{2}[/tex]
[tex]si = \frac{40 \times 12 \times 5}{100 \times 2} [/tex]
[tex]si = \frac{4 \times 12 \times 5}{10 \times 2} [/tex]
[tex]si = \frac{4 \times 12 }{5\times 2} [/tex]
[tex]si = \frac{2 \times 12}{5} [/tex]
[tex]si = \frac{24}{5} [/tex]
[tex]si = 4.8[/tex]

the diameter of a circle is given. find the radius
Answer:
13. r = 7.5cm
14. r = 3.25in
15. r = 1.5 ft
16. r = 4m
Step-by-step explanation:
d/2 = r
Divide the diameter by 2 to get the radius
Answer:
Hey buddy, here is your answer. Hope it helps you .
