.. What is the value of this expression? 6 + (-9) - (-5) i need help on my test can u guys help me and no links because the links u guys give me dont work(no disrespect)
Answer:
-8
Step-by-step explanation:
What is the value of this expression? 6 + (-9) - (-5)
6 + (-9) - (-5)
= 6 - 9 + 5
Following the rules of BODMAS, addition comes first before subtraction
= 6 - 14
= - 8
6 + (-9) - (-5) = -8
Note:
- * - = +
- * + = -
+ * - = -
+ * + = +
Then using BODMAS
B - bracket
O - of
D - division

A - addition
S - subtraction

ayudenme plis
Answer:
a. Velocidad = 16 m/s
b. Deceleración = 0.64 m/s²
Step-by-step explanation:
Dados los siguientes datos;
Tiempo = 25 segundos
Distancia = 400 metros.
a. Para encontrar la velocidad;
Velocidad = distancia/tiempo
Velocidad = 400/25
Velocidad = 16 m/s
b. Para encontrar la desaceleración;
Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.
Deceleración = (v - u)/t
Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.
Deceleración = (0-16)/25
Deceleración = 16/25
Deceleración = 0.64 m/s²

Which statement is true about the equation in the box?
x + 9 - 4x = -3x - 3
A. There is only 1 solution, and x = -3.
B. There is only 1 solution, and x = 9.
C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.
Answer:
D. There is no solution because 9 ≠ -3.
Step-by-step explanation:
For finding out the statement let's check it ourselves
x + 9 - 4x = - 3x - 3
-3x + 9 = - 3x - 3
9 ≠ - 3
So there is no solution for the equation.
hope it helps :)❤

Omar is planning to buy some new baseball shoes. He has already saved $22.50 The shoes cost at least $38 dollars. He writes an inequality to determine how much more he will need to save
Answer:
At least $15.50
Step-by-step explanation:
Omar is planning to buy some new baseball shoes. He has already saved $22.50
The shoes cost at least 38 dollars.
At least means, greater than or equal to which is represented by the sign
≥
The inequality is given as
22.50 + x ≥ 38
x ≥ 38 - 22.50
x ≥ 15.5
Therefore, he would need to save at least $15.50
A fourth grade teacher gives homework every night in both mathematics and language arts. The time to complete the mathematics homework has a mean of 10 minutes and a standard deviation of 3 minutes. The time to complete the language arts assignment has a mean of 12 minutes and a standard deviation of 4 minutes. The time to complete the mathematics and the time to complete the language arts homework has a correlation rho = -0.75. The variance of the time to complete the entire homework assignment is
Answer:
4
Step-by-step explanation:
Given that:
X = time taken to complete mathematics homework
Y= time taken to complete language homework
Standard deviation of X ; SD(X) = 3
Standard deviation of Y ; SD(Y) = 4
rho = - 0.375
rho = Cov(X, Y) / SD(X) * SD(Y)
-0.375 = COV(X, Y) / 3 * 4
COV(X, Y) = 12 * - 0.375
COV(X,Y) = - 4.5
Variance(X, Y) = V(X, Y)
V(X, Y) = V(X) + V(Y) + 2COV(X,Y)
V(X) =SD(X)² = 3² = 9
V(Y) = SD(Y)² = 4² = 16
V(X,Y) = 9 + 16 + 2(-4.5)
V(X, Y) = 16
SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4
Hence, standard deviation to complete entire homework, SD(X, Y) = 4
Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45
Answer:
G(x)=2/15x-6
Step-by-step explanation:
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.
From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,
x/(-6) + y/45 = 1
- 15x + 2y = 90
y = (15/2) x + 45
g(x) = (15/2) x + 45
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

Which ratio is smaller, 32 : 24 or 30 : 22?
Answer:
32 : 24 is smaller
Step-by-step explanation:
32 : 24 = 32/56, reduced is 4/7
30 : 22 = 30/52, reduced is 15/26
a common denominator is 182:
4/7 = 104/182

Mark wants to round to the nearest hundred to estimate the sum of 271 and 582.
He wrote 270 + 580 = 850.
Part A
What mistake did Mark make?
A.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 500: 300 + 500 = 800.
D.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 600 = 900.
00:00
Part B
What is the sum of 271 and 582 rounded to the nearest hundred?
A. 300
B. 850
C. 900
D. 1,000
Answer:
Step-by-step explanation:
Part A:
Mark did not round to the nearest hundreds, he rounded to the nearest tens.
Option A (Incorrect):
271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.
Option B (Incorrect):
271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.
Option C (Incorrect):
271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.
Option D (Correct):
271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.
Part B:
There are two ways to solve this question:
One way:
271 + 582 = 853
Round 853 to the nearest hundred for 900
(Note: Round 853 to the nearest tens for 850.)
Second way:
271 + 582
Round Numbers:
300 + 600
= 900

What is the green dashed line called?
Answer:
The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.
The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.
What is a translation?A translation happens when either a figure or a function are moved horizontally or vertically.
The four translation rules for functions are given as follows:
Left a units: f(x + a).
Right a units: f(x - a).
Up a units: f(x) + a.
Down a units: f(x) - a.
The parent function for this problem is given as follows:
f(x) = x².
For this problem, the parent function was moved:
2 units left, hence g(x) = f(x + 2).
4 units up, hence g(x) = f(x + 2) + 4.
Hence the function g(x) is defined as follows:
g(x) = (x + 2)² + 4.
