Answer:

No, you would graph the y-intercept, you do not graph the m-value (slope). The slope value is the rate that the y-value increases per unit of x. This is how you graph your line from the y-intercept

Answer:

No you are incorrect. <em>The correct answer is (y - intercept) b = -4</em>

Step-by-step explanation:

You need to plot the y - intercept first so that you can create the line using the slope starting from the y - intercept. You can't plot the line unless you first plot a point on the line which would be the y - intercept or -4 THEN from there you use the slope to create the line.

If f(x)= 5x+4 and g(x)= -2+1...... 1) f(6) + g(-8) = ? 2) g(4)= ? 3) f(-2)= ? PLZ PLZ PLZ HELP ME I AM SOOOOO CONFUSED!!!!!!!!!!

MakcuM [25]

Answer:

See below.

Step-by-step explanation:

So we have the two functions:

$f(x)=5x+4\text{ and } g(x)=-2x+1$

1)

First, find the values of each function:

$f(x)=5x+4\\f(6)=5(6)+4\\f(6)=30+4=34$

$g(x)=-2x+1\\g(-8)=-2(-8)+1\\g(-8)=16+1=17$

Therefore:

$f(6)+g(-8)\\=(34)+(17)=51$

2)

Plug in the number into the function:

$g(x)=-2x+1\\g(4)=-2(4)+1=-8+1=-7$

3)

Like the last one:

$f(x)=5x+4\\f(-2)=5(-2)+4=-10+4=-6$

1/3(y - 2) -5/6 (y + 1) =3/4 (y - 3) - 2

Nataly [62]

Answer:

$y=\frac{11}{5}$

Step-by-step explanation:

Given expression

$\frac{1}{3}(y-2)-\frac{5}{6}(y+1)=\frac{3}{4}(y-3)-2$

To solve for $y$ for the given expression.

Solution:

We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.

The multiples of the denominators are:

3 = 3,6,9,<u>12</u>,15

6 = 6,<u>12</u>

4 = 4,8,<u>12</u>

The least common multiple = 12.

Multiplying each term with 12.

$12.\frac{1}{3}(y-2)-12.\frac{5}{6}(y+1)=12.\frac{3}{4}(y-3)-2(12)$

$4(y-2)-10(y+1)=9(y-3)-24$

Using distribution.

$4y-8-10y-10=9y-27-24$

Simplifying.

$-6y-18=9y-51$

Adding $6y$ both sides.

$-6y+6y-18=9y+6y-51$

$-18=15y-51$

Adding 51 both sides.

$-18+51=15y-51+51$

$33=15y$

Dividing both sides by 15.

$\frac{33}{15}=\frac{15y}{15}$

$\frac{33}{15}=y$

Simplifying fractions.

$\frac{11}{5}=y$

∴ $y=\frac{11}{5}$ (Answer)

What is the answer?.....

Butoxors [25]

Answer:

Step-by-step explanation:

f(2) = 2^3 - 4(2)^2 = 8 - 4(4) = 8 - 16 = -8

g(-8)= 4(-8) + 5 = -32 + 5 = -27

Make a subject of r = square root of a / 3

hodyreva [135]

Multiply both sides by 3 to get:

3r = sqrt(A)

Square both sides:

9r^2 = A
