ss7ja [257]

Answer:

The width of the two soccer field must be given by 45\leq w\leq 60.

Assuming two Integers that are solutions of both inequalities are 45 and 60.

Step-by-step explanation:

Let the width of the youth soccer field be 'w'.

Now Given:

the width of the youth soccer field must be at least 45 m.

So we can say that;

w\geq 45 \ m

Also Given:

the width of the youth soccer field must not exceed 60 m.

So we can say that;

x\leq 60

Hence the width of the two soccer field must be given by 45\leq w\leq 60.

So we can say that;

Any Integer lying between integers 45 and 60 can be considered as the width of the youth soccer field.

So let us Assume two Integers that are solutions of both inequalities are 45 and 60.

Answer:

B. y + 7 = -6/5 (x+3)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = − 6 /5 x − 53 /5

Point-slope form:  y + 7 = − 6 /5 ⋅ ( x + 3 )

How to solve 144 upon 125 (exponents) do it step by step​
klasskru [66]

Step-by-step explanation:

<u>How to solve exponent calculations</u>

Simplify each side of the equation. Set the equation equal to zero. Factor the left side of the equation. Set factors equal to zero and solve.

To solve basic exponents, multiply the base number repeatedly for the number of factors represented by the exponent. If you need to add or subtract exponents, the numbers must have the same base and exponent.
