F(x) = 3x - 1
g(x) = 2x - 3
f(2) = 3(2) - 1 = 6 - 1 = 5

g(x) = f(2) => 2x - 3 = 5
2x = 5 + 3 = 8
x = 8/2 = 4
x = 4

One serving of chad's cereal is 1 1/4 ounces. How many servins are in 15 1/3 ounces box?

IrinaK [193]

change the mixed numbers to improper fractions before dividing

1 $\frac{1}{4}$ = $\frac{5}{4}$ and 15 $\frac{1}{3}$ = $\frac{46}{3}$

divide contents of box by a serving

$\frac{46}{3}$ ÷ $\frac{5}{4}$

change ÷ to × and turn the second fraction upside down

= $\frac{46}{3}$ × $\frac{4}{5}$

= $\frac{184}{15}$ = 12.26666 = 12 complete servings

18) Value of b is : $b\geq 8$

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

$12b-46\geq 50$

Solving to find the value of b:

$12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq 8$

So value of b is : $b\geq 8$

Option A is correct.

19) We need to find the correct graph of the equation:

$4y-2$

Solving:

$4y-2$

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.

What is the volume of the following triangular prism?

Eva8 [605]

Answer:

$V=150cm^3$

Step-by-step explanation:

First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.

The area of the triangle is given by the formula:

$A_T=\frac{bh}{2}$

where b is the base: $b=4cm$ and h is the height: $h=5cm$

thus, in this case we have:

$A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2$

And now, the volume will be the area of the triangle multiplied by the length $l=15cm$ of the prism:

$V=A_T*l$

Substituting the known values:

$V=10cm^2*15cm\\V=150cm^3$

The volume in cubic centimeters is 150.
