I need help with ANLGES!!!!

Answer:

75%

Step-by-step explanation:

add them together

Answer:

a. y = 3 × (x + 2)(x - 8)

b.  y = 3·(x - 3)² - 75

c) y =  3·x² - 18·x - 48

Step-by-step explanation:

The x-intercept of the quadratic equation are (-2, 0), (8, 0)

The stretch of the quadratic equation = 3

We have;

a. The factored form y = 3 × (x + 2)(x - 8)

b. From the vertex form, we have;

y = 3 × (x + 2)(x - 8) = 3·x² - 18·x - 48

y = 3·x² - 18·x - 48

The vertex form a(x - h)² + k

Where;

h = -b/(2·a) = 18/6 = 3

h = 3

k = c - b²/(4·a) = -48 - (18²)/12 = -75

The vertex form 3·(x - 3)² - 75

c) The standard form of the quadratic equation, y = a·x² + b·x + c

The standard form of the quadratic equation is y =  3·x² - 18·x - 48.

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal.  Ordered from least to greatest.

Answer:

The order goes Orange, Blue, Red, and Green

Step-by-step explanation:

By dividing the total cost by the amount of square feet, you get the unit value for the wrapping paper per square foot.

Answer:

food [tex]\geq[/tex] 100

favors [tex]\geq[/tex] 50

total [tex]\leq[/tex] 250

Answer:

Step-by-step explanation:

Let x be the number of pants and y be the number of shirts

x + y = 6

20x + 15y = 100

multiply the first equation by -20

-20x -20y = -120

20x + 15y = 100

subtract the equations

-5y = -20

y = 4

replace y in equation 1

x + 4 = 6

x = 2

Answer: 70

Step-by-step explanation:

a^2 + b^2 = c^2

24^2 + b^2 = 74^2

576 + b^2 = 5,476

-576             -576

b^2             =4,900

(square root)

m = 160 - 80/60 - 40

m = 80/20

m = 8/2

m = 4/1

m = 4

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

they have the same variable

Answer:

[tex]a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24[/tex]

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

[tex]3x \: and \: - 6[/tex]

So the correct answer would be

[tex]3x - 6[/tex]

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

Answer:

C) (t-4) + 6=t-10

Step-by-step explanation:

2(a+b)= a+b+a+b

2(a+b)= 2a+b+b

2(a+b)=2a+2b

2(a+b) = 2(a+b)✅

(t-4)+6=t-10

t+2=t-10❌

3y+4y=7y

7y=7y✅

x(5+9)-x=13x

x(14)-x=13x

14x-x=13x

13x=13x ✅

Answer:

Question a)

[tex]9^{3x+4}=27^{4x+3}[/tex]

[tex]x=-0.166[/tex]

Question b)

[tex]4^{3x}=2^{x+1}[/tex]

[tex]x=0.2[/tex]

Step-by-step explanation:

Question a)

Given the expression

[tex]9^{3x+4}=27^{4x+3}[/tex]

Taking log on both sides

[tex]log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)[/tex]

[tex]\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)[/tex]

[tex]3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)[/tex]

[tex]3x+4=1.5\times \left(4x+3\right)[/tex]

[tex]3x+4=6x+4.5[/tex]

[tex]3x=6x+0.5[/tex]

[tex]\frac{-3x}{-3}=\frac{0.5}{-3}[/tex]

[tex]x=-0.166[/tex]

Therefore, the value of x:

[tex]x=-0.166[/tex]

Question b)

Similarly, we can solve the 'b' expression

Given the expression

[tex]4^{3x}=2^{x+1}[/tex]

Taking log on both sides

[tex]log\left(4^{3x}\right)=log\left(2^{x+1}\right)[/tex]

[tex]3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)[/tex]

[tex]3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)[/tex]

[tex]3x=0.5\times \left(x+1\right)[/tex]

[tex]3x=0.5x+0.5[/tex]

[tex]2.5x=0.5[/tex]

Divide both sides by 2.5

[tex]\frac{2.5x}{2.5}=\frac{0.5}{2.5}[/tex]

[tex]x=0.2[/tex]

Therefore, the value of x = 0.2
