4(5+ab) where a=-3.5 and b-0.8

Answer:

Positive

Step-by-step explanation:

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answer:

-10

Step-by-step explanation:

2x+6 = x-4

2x = x - 4 - 6

2x = x -10

2x -x = x-x - 10

x = -10

11,05

Step-by-step explanation:

11 1/20

= (11 × 20 + 1)/20

= (220 + 1)/20

= 221/20 → times 5

= 1105/100

= 11,05

Answer:

11.05

Step-by-step explanation:

To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.

In this case, the value of x would be 5 because 20 × 5 = 100.

Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:

[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]

5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.

Answer:

its either 2/9 or 2/3

Step-by-step explanation:

I solved the top part and got 2/3 and i solved the bottom part and got 1/3 and you can multiply 2/3 and 1/3 and got 2/9

Presumably you're talking about a geometrical interpretation of the identity,

(a + b + c)² = a ² + b ² + c ² + 2 (ab + ac + bc)

a) The linear function that models the amount of water after t minutes is given by:

[tex]V(t) = 200 + 12t[/tex]

b) It takes 92 minutes to completely fill the pond.

Item a:

Then, the function is:

[tex]V(t) = 200 + 12t[/tex]

Item b:

It takes t minutes to fill the pond, t is found for which:

[tex]V(t) = 1304[/tex]

Then

[tex]200 + 12t = 1304[/tex]

[tex]12t = 1104[/tex]

[tex]t = \frac{1104}{12}[/tex]

[tex]t = 92[/tex]

It takes 92 minutes to completely fill the pond.

Answer:

x = 113, y = 67

Step-by-step explanation:

y and 67 are vertically opposite angles.

Vertically opposite angles are equal.

y = 67

x and 67 are linear pair angles.

Sum of linear pair angles is 180,

x + 67 = 180

x = 180 - 67

x = 113

Answer:

0.875

By dividing them

Hope it helps

Answer:

0.875

Step-by-step explanation:

[tex]\frac{7}{8} \times \frac{125}{125} =\frac{875}{1000} =0.875[/tex]

Given equation of the line ,

[tex]\implies 4x - 5y +(-1) = 0 [/tex]

Simplify ,

[tex]\implies 4x - 5y - 1 = 0 [/tex]

Transpose terms to RHS ,

[tex]\implies 5y = 4x - 1 [/tex]

Divide both sides by 5 ,

[tex]\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}[/tex]

Now we know the slope intercept form of the line as [tex] y = mx + c [/tex] we have ,

As we know that the slope of all parallel lines are same . Henceforth ,

Answer:

x = ± 5

Step-by-step explanation:

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5, x = 5
