y = x2 + 4x + 4
y = 2x + 7
How many solutions?
Answer:
2 solutions
Step-by-step explanation:
Given the 2 equations
y = x² + 4x + 4 → (1)
y = 2x + 7 → (2)
Substitute y = x² + 4x + 4 into (2)
x² + 4x + 4 = 2x + 7 ( subtract 2x + 7 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Substitute these values into (2) for corresponding values of y
x = - 3 : y = 2(- 3) + 7 = - 6 + 7 = 1 ⇒ (- 3, 1 )
x = 1 : y = 2(1) + 7 = 2 + 7 = 9 ⇒ (1, 9 )
The 2 solutions are (- 3, 1 ) and (1, 9 )
5. mx + b = c solve for x
Answer:
To solve this, first find the equation of our line. The form of the question gives it to us very directly. We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0To solve this, first find the equation of our line. The form of the question gives it to us very directly. We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

G
A) 12
C) 10
B) 2
D) 7.
Answer:
7
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the opposite interior angles
18x+9 = 5x-5 + 105
Combine like terms
18x+9 = 5x +100
Subtract 5x from each side
18x-5x +9 = 5x+100-5x
13x +9 = 100
Subtract 9 from each side
13x +9-9=100-9
13x= 91
Divide by 13
13x/13 = 91/13
x = 7

"With patience a ruler may be persuaded, and a soft tongue can
break bones." what does this proverb mean?
Answer:
Well rulers don't like to be proven wrong therefore you have to be patient in convincing a ruler that your idea is best. It's pretty much like what inception is in the movie.
A soft tongue is using calm words which in my opinion means you have the utmost confidence in what you're saying. I dont think it literally means bones will break but the person listening will feel as though they are completely wrong if a calm cool person is proving them wrong.
Answer: See answer below
Step-by-step explanation:
Well rulers don't like to be proven wrong therefore you have to be patient in convincing a ruler that your idea is best.
A soft tongue is using calm words which means you have the utmost confidence when speaking. The phrase "break bones" means that a person listening will feel as though they are completely wrong if a calm cool person is proving them wrong.

Rewrite the equation into slope intercept form. y - 4 = 1/5 (x - 5)
Answer:
y = 1/5x + 3
Step-by-step explanation:
y - 4 = 1/5(x - 5)
y - 4 = 1/5x - 1 Distribute numbers to parenthesis
y = 1/5x + 3 Add 4 to both sides

In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°. Find the length of o, to the nearest inch.
Given:
In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°.
To find:
The length of o, to the nearest inch.
Solution:
According to cosine formula,
[tex]a^2=b^2+c^2-2bc\cos A[/tex]
Using cosine formula in ΔOPQ, we get
[tex]o^2=p^2+q^2-2pq\cos O[/tex]
On substituting the values, we get
[tex]o^2=(180)^2+(120)^2-2(180)(120)\cos (171^\circ)[/tex]
[tex]o^2=32400+14400-43200(-0.9877)[/tex]
[tex]o^2=46800+42668.64[/tex]
[tex]o^2=89468.64[/tex]
Taking square root on both sides.
[tex]o=\sqrt{89468.64}[/tex]
[tex]o=299.113[/tex]
[tex]o\approx 299[/tex]
Therefore, the length of o is about 299 inches.
Answer:299

A farmer grows 142 Green pepper plants and 100 a red pepper plants each plant produces about 26 peppers the farmer plans to sell each pepper for three dollars explain to find a reasonable estimate for the total amount of money the Farmer will earn if he sells all of the peppers
Answer:
$18876
Step-by-step explanation:
Given : 142 green pepper plants & 100 red pepper plants, each plant produces 26 peppers, each pepper sells for $3.
Total Peppers = Total pepper plants x peppers per plant
(142 + 100) x 26 = 242 x 26 = 6292
Total expected money income estimate = Total peppers x price per pepper
= 6292 x 3 = 18876
Find the measures of the complementary angles that satisfy each case.
The angles have equal measure.
Answer:
45 degrees and 45 degrees
Step-by-step explanation:
45+45=90
The measure of the two complementary angles will be 45.
What are complementary angles?Complementary angles are those whose combined angle is exactly 90 degrees. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the two angles are complementary to each other.
The complementary angles are the angles having the sum of 45 degrees. The two complementary angles will be calculated as,
45 + 45 = 90
Here one angle is 45 and the other angle is also 45 and the sum of the angles is 90.
Therefore, the measure of the two complementary angles will be 45.
