Answer:

\boxed{x = -4}

Step-by-step explanation:

This drawing illustrates the

equation: -3x – 7 = 5.

Since:

(-x + -x + -x) + (-1 + -1 + -1 + -1 + -1 + -1 + -1) =

(1 + 1 + 1 + 1 + 1) → (-3x) + (-7) = (5) →

-3x – 7 = 5.

To reduce the equation and find x:

[add 7 to both sides to isolate the constant term on the right side]

-3x – 7 + 7 = 5 + 7 →

-3x = 12 →

[divide both sides by -3 to cancel out the coefficient of -3 in -3x to get x]

-3x / -3 = 12 / -3 →

x = -4

Find the range of f(x) = –x + 4 for the domain {–3, –2, –1, 1}.
marishachu [46]

Answer:

\boxed{ \{7, 6, 5, 3 \} }

Step-by-step explanation:

The domain is all possible values for x.

The range is all possible values for f(x) or y.

The domain given is {-3, -2, -1, 1}.

Plug x as {-3, -2, -1, 1} and find the f(x) or y values.

f(-3)=-(-3)+4=7\\f(-2)=-(-2)+4=6\\f(-1)=-(-1)+4=5\\f(1)=-(1)+4=3

The range is {7, 6, 5, 3}, when the domain is {-3, -2, -1, 1}.

Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter
galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

x*0,04+(100000-x-y)*0,05+y*0,06=5250

From the equation it is found that:

y=25000+x

Instead of y, if we put 25000+x the equation will be as following:

x*0,04+75000*0,05+(25000+x)*0,06=5250

From the equation it is found that:

x=5000

Short-Term investment is 5000$

x+25000=y

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$

The picture shows a circular clock face.
marysya [2.9K]

Answer:

[C] 25π square inches

Step-by-step explanation:

<u><em>Given that:</em></u>

<em>the long hand of the clock is about 5 inches long.</em>

<u><em>To Find:</em></u>

<em>What is the approximate area of the clock face?</em>

<u><em>Solve:</em></u>

<em>Formula - </em><em>A =πr²</em>

<em>Note that;</em>

<em>π = 3.14 (about)</em>

<em>Radius - 5 inches</em>

<em>A =πr²</em>

<em>A = 3.14(5)²</em>

<em>A = 3.14(25)</em>

<em>A = 78.5</em>

<em>Now let see the answer choices:</em>

<em>A.  5π square inches                     ≈   5(3.14) = 15.7</em>

<em>B. 10 π square inches                    ≈  10(3.14) = 31.4</em>

<em>C. 25 π square inches                    ≈  25(3.14) = 78.5</em>

<em>D. 100 π square inches                    ≈ 100(3.14) = 314</em>

<em />

<em>Hence, the answer is [C] 25 π square inches </em>

<em />
