x=3/2+1/2√21 or x=3/2+-1/2√21
Step-by-step explanation:
For this equation: a=1, b=-3, c=-3
1x2+−3x+−3=0
Step 1: Use quadratic formula with a=1, b=-3, c=-3.
x=−b±√b^2−4ac/2a
x=−(−3)±√(−3)^2−4(1)(−3)/2(1)
x=3±√21/2
x=3/2+1/2√21 or x=3/2+−1/2√21
Answer:
3: x= 3.7912874, x= 0.79128784
4: x= 0.62181997, x= -4.28848664

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [
Answers
Answer:
y = 4x+3
Step-by-step explanation:
The equation in point slope form is expressed as y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
If a line is parallel to y = 4x + 1, the slope of the line m = 4
Substitute m = 4 and the point (-2, -5) into the equation above;
y - (-5) = 4(x - (-2))
y+5 = 4(x+2)
y+5 = 4x+8
y = 4x+8-5
y = 4x + 3
Hence the equation of the line is y = 4x+3

Find out the number of ounces of red paint needed to make 3 cups of dark orange paint
Let
x -----> number of ounces of red paint

Alex is trying to save $230 to buy a new tablet. Right now, he has $40 and can save $38 a week from
his allowance. Write and solve an inequality that can be used to find the minimum number of weeks it
will take Alex to have the money to buy the tablet. Write a sentence to interpret your solution.
Answers
Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

If ∠ G is supplementary to ∠ H and the measure of ∠ G is 65 ° what is the measure of ∠ H ?
Please help
Answers
180 - 65 = 115
So angle H = 115 degrees
Measure of ∠H = 115°
What are supplementary angles?Two angles are called supplementary when sum of their measures is 180 degrees.
Given,
∠G is supplementary to ∠H
∠G is 65 °
∠G + ∠H = 180°
65° + ∠H = 180°
∠H = 180° - 65°
∠H = 115°
Hence, 115° is measure of ∠H .
