Equation is y = -1/4x + 5

Step-by-step explanation:

Step 1: Given slope, m = -1/4 and y-intercept, b = 5. Write the equation in slope intercept form which is y = mx + b

⇒ y = -1/4x + 5

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

SVEN [57.7K]

(g-f)(x)=g(x)=f(x)

(g-f)(x)=6x-4+x^2

(g-f)(x)=x^2+6x-4 then:

(g-f)(3)=3^2+6*3-4

(g-f)(3)=9+18-4

(g-f)(x)=23

4x+8y=17<br> Solve for y

olasank [31]

Answer:

4x + 8y = 17

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8

Then simplify the fractions to get:

y = -2x/4 + 17/8

Ricky has 3/4 of a bag of Skittles. He wants to split the rest between between his 5 friends. What fraction of the bag will each

Wittaler [7]

Answer:

3/20, with the assumptions below.

Explanation:

The question seems incomplete.

In order to show you the procedure, I make some assumptions.

Assuming that Ricky wants to split the full content of the 3/4 of a bag between his 5 friends, to find what fraction of the bag will each friend receive you must divide 3/4 by 5.

The operation is:

$\dfrac{3}{4}\div 5$

Convert the whole number 5 into fraction using 1 as denominator:

$\dfrac{3}{4}\div \dfrac{5}{1}$

Transform the division into multiplication changing the divisor into its reciprocal:

$\dfrac{3}{4}\times \dfrac{1}{5}$

Multiply numerator with numerator and denominator with denominator:

$\dfrac{3\times 1}{4\times 5}=\dfrac{3}{20}\leftarrow answer$

A line passes through the points (0, 4) and (1, 9). What is its equation in slope-intercept

Simora [160]

Answer:

y=5x+4

Step-by-step explanation:

First get slope:

(4-9)/(0-1) = -5/-1 = 5

The y-intercept is where the graph hits the y-axis. That is also the point on the graph where x = 0. We are already given that, with point (0,4).

The y-intercept is 4.

y = mx +b, m is slope and b is the intercept.

y = 5x +4
