Answer:
(5/2, - 7/6)Step-by-step explanation:
12x² - 16x - 35 = 012x² + 14x - 30x - 35 = 02x(6x + 7) - 5(6x + 7) = 0(2x - 5)(6x + 7) = 01)
2x - 5 = 0 2x = 5x = 5/22)
6x + 7 = 06x = - 7x = - 7/6The point D(4,
–
6) is rotated 180° clockwise around the origin. What are the coordinates of the resulting point, D'?
Answer:
(-4,-6)
Step-by-step explanation:
If your point D were to start at (4,6), the first 90° clockwise rotation would have the point land on (4,-6), the second would have point D land on (-4,-6). A faster way to do this without making 2 90° clockwise rotations, is you flip it diagonally across the center point, if the center point is 0, you would flip both signs (positive would become negative and the other way around).
The rotation of point about 180 degree is D(4, 6)----> D'(4, -6).
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
We have,
The points D(4, 6).
We know the rule for 180 degree rotation is
(x, y) ----> (x, -y).
So, the rotation of point about 180 degree is
D(4, 6)----> D'(4, -6).

A city’s annual rainfall totals are normally distributed, and the probability that the city gets more than 43.2 inches of rain in a year is given by P (z greater-than-or-equal-to 1.5) = 0.0668. If the standard deviation of the city’s yearly rainfall totals is 1.8 inches, what is the city’s mean annual rainfall?
40.5 inches
41.4 inches
45.0 inches
45.9 inches
Answer: So the answer wont be C or D because it doesn't get over 43.2 inches of water so if you do 43.2 -- 1.8 it will equal 41.4 inches
MARK ME BRAINLIEST!!!!!!!!!!!!!!!
The city's mean annual rainfall is 40.5 inches, option A is correct.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
We know that P(z ≥ 1.5) = 0.0668
From the standard normal distribution table, we can find that the z-score corresponding to a right-tailed probability of 0.0668 is approximately 1.5. Therefore, we have:
z = 1.5
We can use the formula for the z-score:
z = (x - μ) / σ
where x is the observed value, μ is the mean, and σ is the standard deviation.
Substituting the given values, we get:
1.5 = (43.2 - μ) / 1.8
Solving for μ, we get:
μ = 43.2 - 1.8 × 1.5 = 40.5
Therefore, the city's mean annual rainfall is 40.5 inches.

The total score in a football game was 31 points.
The winning team scored 19 points more than the losing team.
How many points did the winning team score?
Answer:
25
Step-by-step explanation:
First we need to create an equation. We’ll say the losing team scored x points. If the winning team scored 19 more, they would have x + 19 points. We know the total is 31 points, so we end up with x + x + 19 = 31, or 2x + 19 = 31. Subtract 19 from both sides to get 2x = 12. Divide both sides by 2, and get x = 6. To find out how much the winning team scored, which we know is x + 19, put 6 in for x and get 25.

Which number, when placed in the blank, makes the inequality FALSE? _____ > 8
Hi!
I can help you with joy!
Recall that the sign ">" means "greater than"
So, we need to find a number that would make the inequality false.
Is it 9? Nope, 9 is greater than 8, so 9 would make the inequality true.
So, we need to find a number less than 8.
Is it 7? Yes, 7 is less than 8, so 7 would make the inequality false.
7>8 (False)
Hope it helps!
Enjoy your day!
[tex]\bf{GracefulGirl[/tex]
Answer:
Anything under 8.
Step-by-step explanation:
Anything under 8, (7, 6, 5, 4, etc.) would make the inequality false. "Inequality" means difference in size, degree, circumstances, etc.; lack of equality. ">" means greater than, so, to make the equation false, insert something less than 8.

X^2+y^2=128
Find the intersection of the line and the circle
Answer:
(-8, 8)
Step-by-step explanation:
Plug in the y from the top equation into the y of the bottom equation
x² + (x + 16)² = 128
x² + x² + 32x + 256 = 128
Subtract 128 from both sides to make it equal to zero
2x² + 32x + 256 = 128
- 128 - 128
2x² + 32x + 128 = 0
Divide both sides by 2
(2x² + 32x + 128)2 = 0/2
x² + 16x + 64 = 0
Factor the equation
(x + 8)(x + 8) = 0
We see that x will have to be -8 for it to equal zero
so x = -8
Plug the new x into one of the original equations; let's use the top one
y = -8 + 16
y = 8

Euclid Street is parallel to Lambert Street. City Hall is
located between the streets. From City Hall, a straight
road leads to Euclid Street, intersecting it at a 51°
angle. Another straight road leads to Lambert Street,
intersecting it at a 37° angle. Find X. EXPLAIN and
show your method.
Answer:
88
Step-by-step explanation:
Imagine a line through City Hall parallel to the given streets. The angle between that and the path to Euclid Street is 51°, congruent with the alternate interior angle marked 51°.
The angle between our imaginary line and the path to Lambert Street is 37°, congruent with the alternate interior angle marked 37°.
The value of x° is the sum of those two angles:
x° = 51° +37°
x = 88
__
Alternate solution
If you extend the path to Euclid Street until it intersects Lambert Street, the alternate interior angle theorem tells you the angle it makes with Lambert Street is 51°. The angle x° is an external angle to the triangle that now has 51° and 37° as remote interior angles. As such, x is the sum of 51 and 37:
x = 51 +37 = 88
