*Yes, B, C, and D are correct. -15, -10.5, and -7.5 are solutions to x<-7*........................... ...................................................................................................................................... *8y – 24 > –16............................................................................................................. 8y>8 ADD 24 to both sides ....................................................................................... y>1 so C. divide both sides by 8................................................................................. It is not A because the opposite of subtracting 24 is adding 24. So you add 24 to both sides to undo the subtraction. -16+24=8 Then you divide both sides by 8, which gives you y>1. I think you probably subtracted 24 from -16 instead of adding it.*......................................... ...................................................................................................................................... *I'm not sure what to make of the third one, is that a number line or...?*............................... ...................................................................................................................................... *- t/5 ≥15 ........................................................................................................................ -t ≥ 75 MULTIPLY both sides by 5.................................................................................... t ≤ -75 divide both sides by -1, and flip the sign, because when dividing an inequality by a negative number you must flip the sign.............................................................................. So A would be correct. .................................................................................................... I believe if you divided the 15 by 5 and didn't flip the sign you would get D.*......................... Also, sorry, my enter key isn't working right, so it's all scrunched together.

Factoring is a common mathematical process used to break down the factors, or numbers, that multiply together to form another number. Some numbers have multiple factors.

Explanation:

Factoring polynomials involves breaking up a polynomial into simpler terms (the factors) such that when the terms are multiplied together they equal the original polynomial. Factoring helps solve complex equations so they are easier to work with. Factoring polynomials includes: Finding the greatest common factor.

Factoring (called "Factorizing" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.

Type the correct answer in each box. A circle is centered at the point (5, -4) and passes through the point (-3, 2). The equatio

Answer:

$(x+ \boxed{-5})^2+(y+\boxed4)^2=\boxed{100}$

Step-by-step explanation:

Given:

Center of circle is at (5, -4).

A point on the circle is $(x_1,y_1)=(-3, 2)$

Equation of a circle with center $(h,k)$ and radius 'r' is given as:

$(x-h)^2+(y-k)^2=r^2$

Here, $(h,k)=(5,-4)$

Radius of a circle is equal to the distance of point on the circle from the center of the circle and is given using the distance formula for square of the distance as:

$r^2=(h-x_1)^2+(k-y_1)^2$

Using distance formula for the points (5, -4) and (-3, 2), we get

$r^2=(5-(-3))^2+(-4-2)^2\\r^2=(5+3)^2+(-6)^2\\r^2=8^2+6^2\\r^2=64+36=100$

Therefore, the equation of the circle is:

$(x-5)^2+(y-(-4))^2=100\\(x-5)^2+(y+4)^2=100$

Now, rewriting it in the form asked in the question, we get

$(x+ \boxed{-5})^2+(y+\boxed4)^2=\boxed{100}$

Answer:

300 g

Step-by-step explanation:

The problem statement tells us ...

36g = 0.12×d . . . . . where d represents the daily value

36g/0.12 = d = 300g . . . . divide by the coefficient of d

300 g of carbohydrates per day are recommended.
