Hi, there!!!

It's so simple, 

so, let's simply work with it;

Here, the given equation is;

4d-4 = 5d-8

so, let's take "4d" to right side and -8 to left side. we get,

-4+8 = 5d-4d

or, 4 = d

Therefore, the value of d is 4.

{here, we simply simplified to get answer}

YOU ARE ABSOLUTELY RIGHT...

Hope it helps....

Find a polynomial f(x) of degree 4 that has the following zeros. 7, −3, 0, −2

HACTEHA [7]

Answer:

x^4 - 2x^3 - 29x^2 - 42x

Step-by-step explanation:

Equal all the zeros to x then move them over.

x=7,x=-3,x=0,x=-2

x-7,x+3,x+0,x+2

Then multiply each factor

(x-7)(x+3)(x)(x+2)

x^4 - 2x^3 - 29x^2 - 42x

A line has a slope of 9 and a y-intercept of 5.What is its equation in slope-intercept form

salantis [7]

Answer:

y=9x+5

Step-by-step explanation:

y=mx+b is the slope-intercept form where m is the slope and b is the y-intercept.

Given that m (the slope) = 9 and b (the y-intercept) = 5, we can substitute directly into the equation and get this answer:

y=9x+5

Ollie is catering a dinner party for more than 26 guests. Each guest has a choice between a vegetarian dinner or a steak dinner.

Ratling [72]

Using the graph that is included, look at the points given. For example (30, 3). There would be 30 vegetarian dishes and 3 steak dinners for a total of 33 meals. If that is plugged into the cost equation 20(30)+3(30) it would equal $690. The next point (33, 1) would cost 20(33) + 30(1) = $690 and but gives 34 meals. However, 34 vegetarian meals would only cost 20(34)=$680 and have 34 meals.

If both types of meals need to be purchased, 33 vegetarians and 1 steak. If only vegetarians are purchased, the cost is cheaper by $10.

An acute angle of a right triangle measures 30°, and the length of the triangle's hypotenuse is 10 ft. Find the missing angle me

OlgaM077 [116]

Answer:

missing angle <60 and side lengths 5, 5 $\sqrt{3}$

Step-by-step explanation:

we understand from the given information that the triangle in question is a special right triangle

and since this is a special triangle the side lengths follows :

the side length that sees <90 is represented by 2x

the side length that sees <60 is represented by x $\sqrt{3}$

and the side length that sees <30 is represented by x

2x = 10 so x = 5 and x $\sqrt{3}$ = 5 $\sqrt{3}$
