4) x*2x=
2x^2
9) 5x+2*x+3=
5x^2+17x+6
i think these are right lol gl
Answer:
The slope is -63. It is how many cans that go away each day.
Step-by-step explanation:
The y intercept is the y value when x =0
It is the number of canned goods we start with.
The slope is -63. It is how many cans that go away each day.
The equation can be written in the form
y= mx+b where m is the slope and b is the y intercept
y = -63x +825
Let
x-------------> pounds of granola-----------> <span>$3 per pound
</span>y-------------> pounds of raisins-----------> $2 per pound
z------------ > price per <span>pounds of the trail mix
</span>
we have that
z=3x+2y--------------------- > this is the equation
for x=3 pounds of granola and y=<span>0.75 pounds of raisins
z=3*3+2*0.75=</span>$10.5 of <span>trail mix</span>
Answer:
a. attached graph; zero real: 2
b. p(x) = (x - 2)(x + 3 + 3i)(x + 3 - 3i)
c. the solutions are 2, -3-3i and -3+3i
Step-by-step explanation:
p(x) = x³ + 4x² + 6x - 36
a. Through the graph, we can see that 2 is a real zero of the polynomial p. We can also use the Rational Roots Test.
p(2) = 2³ + 4.2² + 6.2 - 36 = 8 + 16 + 12 - 36 = 0
b. Now, we can use Briott-Ruffini to find the other roots and write p as a product of linear factors.
2 | 1 4 6 -36
1 6 18 0
x² + 6x + 18 = 0
Δ = 6² - 4.1.18 = 36 - 72 = -36 = 36i²
√Δ = 6i
x = -6±6i/2 = 2(-3±3i)/2
x' = -3-3i
x" = -3+3i
p(x) = (x - 2)(x + 3 + 3i)(x + 3 - 3i)
c. the solutions are 2, -3-3i and -3+3i
Answer:
Step-by-step explanation:
y-(-4)= 7/4(x-(-4)
Y+4= 7/4x +4
Y = 7/4x
