how many x intercepts are in y = x 2+ 4x + 5
Answer:
0 x-intercepts
Step-by-step explanation:
In order to find the x-intercepts ,you need to solve this equation
x² + 4x + 5 = 0 for x and see how many solutions you get:
x² + 4x + 5 = 0
∆ = 4² - 4×1×5 = 16 - 20 = -4
since ∆ < 0 Then the equation has no solution then our Function has none x-intercepts.

Select from the drop-down menus to correctly complete each statement.
A hamburger patty has approximately
Choose...
grams of protein per ounce.
The fish has approximately
Choose...
grams of protein per ounce.
Answer:
Hamburger patty is 5.67 per ounce and the fish is 5.33 per ounce
Step-by-step explanation:
The hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
[tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein
[tex]4\frac{1}{2}[/tex] = 9/2
[tex]25\frac{1}{2}[/tex] = 51/2
Let's suppose each hamburger patty has x grams of protein so the value of x:
[tex]\rm x = \frac{\frac{51}{2}}{\frac{9}{2} }[/tex]
x = (51/2)×(2/9)
x = 5.66 ≈ 5.7 grams of protein
For fish Let's suppose each fish has y grams of protein so the value of y:
[tex]\rm y =\frac{32}{6}[/tex]
y = 5.3 grams of protein
Thus, the hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.

Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
y = - 3x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (2, - 10) ← 2 ordered pairs from the table
m = [tex]\frac{-10+7}{2-1}[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (2, - 10) , then
- 10 = - 6 + c ⇒ c = - 10 + 6 = - 4
y = - 3x - 4 ← equation of linear function

When the chords intersect inside the circle the sum of the vertical angles and the sum of the referenced arcs are the same. Since the vertical angles are congruent, each is half the sum of the referenced arcs.
Similarly when the chords intersect outside the circle, the angle is half the difference of the arc measures.
It's the same with a tangent; in that case there's just not a part of the arc that's not counted on the side with the tangent.
OK, that's how. Let's try some.
1. x = (88 + 86)/2 = 87
2. x = (150 - 60)/2 = 45
3. The angle is exactly half the subtended arc,
x = 110/2 = 55
4. The referenced arc is 360 - 220 = 140 degrees and x is half, 70.
5. Outside, half the difference, x = (90-20)/2 = 35
6. Angle outside, inner arc 6 degrees, vertical angle is 90 degrees.
90 = (x - 6)/2
180 = x - 6
x = 186
7. There's a special rule for this case but we can treat it as outside, little arc x, big arc 360-x,
60 = (360 - x - x)/2
120 = 360 - 2x
2x = 240
x = 120
8. Inner arc x, outer arc is 360-140-x = 220-x. Half the difference is 38,
38 = (220 - x - x)/2
76 = 220 - 2x
2x = 220 - 76
x = (220 - 76)/2 = 72
9. x is formed by a tangent and a radius, so a right angle, x=90
y is subtended by a 35 degree angle so y=70
10. Remaining triangle angle is 180 - 62 - 28 = 90. Arc that subtends it is double, 180. That means the long side is a diameter.
11. Remaining triangle angle is 180 - 50 - 70 = 60. x=120, y=100, z=140
12. Remaining arc 360 - 170 - 90 = 100. Angles are half.
x=45, y=50, z=85

The first four iterates of the function f(x) are 23, 163, 1143 and 8003
The function is given as:
[tex]f(x) = 7x + 2[/tex]
Where:
[tex]x_o=3[/tex]
Substitute 3 for x in f(x)
[tex]f(3) = 7 \times 3 + 2[/tex]
[tex]f(3) = 23[/tex]
Substitute 23 for x in f(x), for the next iteration
[tex]f(23) = 7 \times 23 + 2[/tex]
[tex]f(23) = 163[/tex]
Substitute 163 for x in f(x), for the next iteration
[tex]f(163) = 7 \times 163 + 2[/tex]
[tex]f(163) = 1143[/tex]
Substitute 1143 for x in f(x), for the next iteration
[tex]f(1143) = 7 \times 1143 +2[/tex]
[tex]f(1143) = 8003[/tex]

Probability for flipping a coin twice and getting heads: 1/2
Probability for flipping a coin twice and getting tails: 1/2
Probability for getting heads AND tails: 0
Probability for getting heads or tails: 1/2

x squared + 12x +3 = 7 solve by completing the square
Answer:
x = -6 ± 2sqrt(10)
Step-by-step explanation:
x^2 + 12x+3 = 7
Subtract 3 from each side
x^2 +12x = 4
Take the coefficient of x
12
Divide by 2
12/2 = 6
Square it
6^2 =36
Add this to each side
x^2 +12x +36 = 4+36
(x+6)^2 = 40
Take the square root of each side
sqrt((x+6)^2) =± sqrt(40)
x+6 = ± sqrt(40)
x+6 = ± sqrt(4)sqrt(10)
x+6 =± 2sqrt(10)
Subtract 6 from each side
x+6-6 = -6 ± 2sqrt(10)
x = -6 ± 2sqrt(10)
Answer:
(x + 6)² = 40 → x = ±2√10 - 6
Step-by-step explanation:
x²+12x+3=7 can be solved by completing the square
To do so we must first find the term we are adding to both sides of the equation by using [tex](\frac{b}{2} )^2}[/tex]
In this case, our b is 12, so plugging this into the formula we get [tex](\frac{12}{2} )^{2} =6^{2} =36[/tex]
We first need to subtract the 3 from both sides of the equation to get x²+12x=4
We then can add the 36 to both sides of the equation: x² + 12x + 36 = 4 + 36 → x² +12x + 36 = 40
Now we are able to factor the left side of the equation to get (x + 6)² = 40
To solve for x we need to take the square root of both sides [tex]\sqrt{(x+6)^{2} } =\sqrt{40}[/tex] to get x + 6 = ±2√10
Then we need to subtract 6 from both sides to get x = ±2√10 - 6

Triangle DEF is similar to triangle ABC. What is the length of segment EF? (HINT use scale factor) (Leave answer as a fraction)
We have been given two similar triangles. We are asked to find the length of segment EF.
We know that corresponding sides of similar triangles are proportional, so we will use proportion to solve our given problem.
[tex]\frac{EF}{DF}=\frac{BC}{AC}[/tex]
Upon substituting measure of our given side lengths, we will get:
[tex]\frac{EF}{1}=\frac{5}{13}[/tex]
[tex]EF=\frac{5}{13}[/tex]
Therefore, the length of segment EF is [tex]\frac{5}{13}[/tex] units.
