Using a linear function, the statement that best describes when she advances to the next phase is: 75 + 3x > 90.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering that she already has 75 points, and earns 3 points for each correct answer, her score is modeled by the following function:
T = 75 + 3x.
She advances to the next phase if she scores over 90 points, hence the statement is:
T > 90
75 + 3x > 90.

What is the equation in standard form?
Answer:
just cause
Step-by-step explanation:
Slope:
8
y-intercept:
2
5. Choose the best answer.
Find the slope and y-intercept of the equation; then choose the equation in slope-Intercept form.
3.3x– 3y = 2.4
slope
y -intercept
slope-intercept form
The slope-intercept form: y = mx + b
So we need to "solve" given equation for y
3.3x - 3y = 2.4 {subtracting 3.3x from both sides}
- 3y = 2.4 - 3.3x {dividing both sides by (-3)}
y = -0.8 + 1.1x
Therefore:
Slope: m = 1.1y -intercept : b = - 0.8slope-intercept form: y = 1.1x - 0.8I dont know why it says im in high school im in middle school. But anyways can someone please explain how to get percentage.
Answer:
Step-by-step explanation:
To change a decimal into a percent you multiply by 100.
If there is a fraction that you need to convert into a percent. Completely divide the fraction. 4/5 = 0.8 then multiply by 100 you get 80%. This means that 4 is 80% of 5
Answer:
how to get a percentage from a decimal is when you take the decimal point and move it twice to the left
Step-by-step explanation:
for example
.07 = 7%
does that make sense?

Answer:
Angle 6=57 angle 5= 123
Step-by-step explanation:
angle 6 is congruent to angle 3, which is 57 degrees
To find angle 5, we look at both angles 5 and 6's lines. The lines show us that both angles equal to 180, so we subtract 57 from it.

students are girls?
Answer:
16
Step-by-step explanation:
[tex]no \: of \: girls = \frac{4}{5 + 4} \times 36 \\ \\ = \frac{4}{9} \times 36 \\ \\ = 4 \times 4 \\ \\ = 16[/tex]
Answer:
Step-by-step explanation:
let the ratio of boys and girls be 5x and 4x
According to question,
5x+4x = 36
or, 9x= 36
x=4
number of boys = 5x
= 5·4= 20
number of girls = 4x
= 4.4=16
therefore the total no of boys is 20 ans girls is 16

Answer:
B y = 1.1x^2 +4.2x - 4.9
Step-by-step explanation:
For this one, try plugging in 1.
y = 1.1(1)^2 + 4.2(1) - 4.9
1.1 + 4.2 - 4.9
1.1 + 4.2 = 5.3
5.3 - 4.9 = 0.4
0.4 is the closest for (1, 0.3)
So the correct answer is B. All the others don't make sense and are not close enough.

the vertices of xyz are x (1,-4)
Answer:
5. The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)
6. The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)
Step-by-step explanation:
If the point (x, y) translated by T → (h, k), then its image is (x + h, y + k)
#5
In ΔXYZ
∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)
∵ T → (-4, -3)
∴ h = -4 and k = -3
→ Use the rule above to find the image of the vertices of the Δ
∵ X' = (1 + -4, -4 + -3)
∴ X' = (-3, -7)
∵ Y' = (-2 + -4, -1 + -3)
∴ Y' = (-6, -4)
∵ Z' = (3 + -4, 1 + -3)
∴ Z' = (-1, -2)
∴ The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)
#6
In ΔXYZ
∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)
∵ T → (5, -3)
∴ h = 5 and k = -3
→ Use the rule above to find the image of the vertices of the Δ
∵ X' = (1 + 5, -4 + -3)
∴ X' = (6, -7)
∵ Y' = (-2 + 5, -1 + -3)
∴ Y' = (3, -4)
∵ Z' = (3 + 5, 1 + -3)
∴ Z' = (8, -2)
∴ The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)

Step-by-step explanation:
Find the nth term of this quadratic sequence
4,9, 16, 25, 36,
Answer:
[tex]a_{n}[/tex] = (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
[tex]a_{n}[/tex] = (n + 1)²
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b. Her work is shown below.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
Which best describes the error in Tawanna’s solution?
Tawanna factored one or both pieces of the expression incorrectly.
Tawanna did not include each factor in the GCF.
Tawanna should have used each common factor once.
Tawanna included only one of the variables in her solution.
Mark this and return
Answer:
Tawanna should have used each common factor once.
Step-by-step explanation:
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
GCF = Greatest common factor
She has calculated the GCF incorrectly as she should use each common factor once only. But she has taken all the common factors twice which is wrong.
Hence, the error in Tawanna’s solution is that "Tawanna should have used each common factor once.". Hence, the correct option is (c).
Answer:
C - Tawanna should have used each common factor once.
