1.8 minus 3.7 x = negative 4.2 x + 0.3?

Mathematics

AVprozaik [17]3 years ago

Combine like terms. First, add 4.2x to both sides. This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.

Next, 0.05x = -1.5, or 5x = -150, and x = -30.

Must check this result by substitution of -30 for x in the original equation.

Is 1.8-3.7(-30)=-4.2(-30)+0.3 true or false?

If the graph of f(x) = |x| is shifted up 5 units, what would be the equation of the new graph?
inna [77]

Answer:

B. g(x)= |x| + 5

Step-by-step explanation:

-5 represents a vertical shift down, so that narrows it down to either A or B. A shows a shift across the horizontal (X) axis, so it must be B.

Hi Help me with question 6b) pls
Romashka-Z-Leto [24]

Answer:

k = 9

Step-by-step explanation:

Consider the pattern on the right side , that is

T_{k} = k(k + 2) + 1 = k² + 2k + 1

Equating

k² + 2k + 1 = 100 ( subtract 100 from both sides )

k² + 2k - 99 = 0 ← in standard form

(k + 11)(k - 9) = 0 ← in factored form

Equate each factor to zero and solve for k

k + 11 = 0 ⇒ k = - 11

k - 9 = 0 ⇒ k = 9

But k > 0 , then k = 9

Which is the constant term of the algebraic expression -2x^2+17-15x+7xy?
andrew11 [14]
The given expression is
-2x² + 17 - 15x + 7xy

The algebraic expression may be written as
-2x² + 7xy - 15x + 17

The constant term does not contain either x or y.
Therefore  17 is the constant term.

Answer: 17
