Answer:

4

Step-by-step explanation:

To find the area of a rectangle, you multiply adjacent side lengths, so in this case it would be (x + 3)(4x - 7) which expands to 4x^2 + 5x - 21.

What is the slope and y intercept of y=-7x+12
MrRissso [65]
Hi there!

So the format of slope-intercept form is:

y= mx+b

m= your slope
x = just a variable
b= your y- intercept

Using those hints, see if you can figure out the answer! :)

Hope this helped!

Janice has 15 pets. Each of her pets is either a dog or a bird. If her pets have a total of 38 legs, how
balu736 [363]

<em>Hi!</em>

<em></em>

<em>These can be set up as systems of equations.</em>

<em> </em>

<em>Let b = the number of birds, and let d = the number of dogs.</em>

<em> </em>

<em>b + d = 21</em>

<em> </em>

<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>

<em> </em>

<em>You can solve this using either elimination or substitution.</em>

<em>Consider marking brainliest.</em>

A system of two equations contains one quadratic equation and one linear equation. the quadratic system of the equation is y=x^2
ruslelena [56]
Suppose the line is y=mx+b
when x=3, y=15, so 15=3m+b
when x=-1, y=-13, so -13=-m+b
solve the system of these two equation, you get m=7, b=-6
so the linear equation is y=7x-6
