Y = x² + 2x - 8
which two numbers add up to 2 and multiply to -8?
-2 and 4
so rewrite the expression using the above;
(x - 2)(x + 4)
x = 2, -4
so the zeros are 2 and -4.
hope this helps, God bless!
Step-by-step explanation:
ΔACX is an isosceles triangle, so ∠AXC = ∠XAC. We'll call the measure of this angle x°.
∠AXC and ∠BXC are supplementary, so ∠AXC + ∠BXC = 180. That means ∠BXC = 180 − x.
ΔBXC is an isosceles triangle, so ∠XBC = ∠XCB. We'll call the measure of this angle y°.
Angles of a triangle add up to 180, so:
y + y + (180 − x) = 180
2y = x
y = x/2
∠ACX and ∠XCB are complementary, so ∠ACX + ∠XCB = 90.
x + y = 90
x + x/2 = 90
3/2 x = 90
x = 60
Therefore, ∠AXC = ∠XAC = 60°.
Answer:
y+9
Step-by-step explanation:
first square the 3
3 squared is 9
after that you can see there are no terms with y
so you can't solve it much more
y+9 cannot be solve so that's ur answer
Answer:
%60.66666...
Step-by-step explanation:
<u>Step 1: Make an equation to represent</u>
Percent change of the numbers six and four
6x = 4
<u>Step 2: Divide both sides to get a decimal</u>
6x / 6 = 4 / 6
x = 0.6666....
<u>Step 3: Convert into a percentage</u>
x = 0.6666.... * 100
x = %60.66666...
Answer: %60.66666...
<u>If you meant the other way:</u>
4x = 6
4x / 4 = 6 / 4
x = 1.5
x = 1.5 * 100
x = %150
Answer:
The distribution of the sampled means becomes normally distributed (bell shaped) as the sample size increases.
Explanation:
According to the Central Limit Theorem, if the mean values for increasing sample sizes are obtained, the distribution of sample means will be normally distributed, even if the individual samples do not have normal distributions.
Typically, sample sizes of 30 or greater are recommended.
