Yes, as long as you like it. (For what it's worth, I think that's a pretty name, and I'm glad you don't want to name a kid something horrendous like Blanket or Apple.)

frez [133]

When x=4

y = 4x+19 = 4(4)+19 = 16+ 19 = 35

Answer: 35

Not sure what the other equation was for.

What is the volume of the frustum? A. 503.77 B. 147 C. 588 D. 258.47

Studentka2010 [4]

V = 1/3 πh(R^2 +r^2 + R*r)

V = 1/3 (3.14)(14) (4.2^2 + 2.5^2 + 4.2 * 2.5)

V = 1/3 (3.14)(14) (17.64 + 6.25 + 10.5)

V = 1/3 (3.14)(14) (34.39)

V = 503.93

Because i'm using π = 3.14

So answer is B. 503.77

For the function f(x)=−7x2+8x−8, find f(4).

Jet001 [13]

Answer:

- 88

Step-by-step explanation:

$f(x ) = - 7 {x}^{2} + 8x - 8 \\ plug \: x = 4 \\ \\ \implies \: f(4 ) = - 7 {(4)}^{2} + 8(4) - 8 \\\\ \implies \: f(4 ) = - 7 \times 16 + 32 - 8 \\\\ \implies \: f(4 ) = - 112+ 32 - 8 \\ \\ \implies \: f(4 ) = - 120+ 32 \\\\ \implies \: f(4 ) = - 88 \\$

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalen

melomori [17]

Answer:

Both expressions should be evaluated by substituting with one value for x. If the final values of the expressions are the same, then the two expressions must be equivalent.

The table represents a function.

Zarrin [17]

We have to complete the statement:

" The rate of change in the function y=x+4 is ______ the rate of change of the function represented in the table."

Let us consider the function represented in table.

The coordinates given in the table are:

(0,6) (2,8) (4,10) and (6,12)

Consider the first two coordinates (0,6) and (2,8)

$x_{1}=0 , y_{1}=6, x_{2}=2 , y_{2}=8$

Equation of line is given by $(y-y_{1})=m(x-x_{1})$

where 'm' is slope(rate of change) is given by the formula:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

So, $m = \frac{8-6}{2-0}=1$

So, equation of line is :

(y-6)= 1 (x-0)

y-6=x

y=x+6

Comparing it with standard equation of line y=mx+c with slope 'm'.

So, we get m(Rate of change)=1.

Now,

We will find the rate of change(slope) in the function y=x+4

Comparing it with standard equation of line y=mx+c with slope 'm'.

So, we get m(Rate of change)=1.

So, " The rate of change in the function y=x+4 is equal to the rate of change of the function represented in the table.
