Answer:
32 guitar lessons
Step-by-step explanation:
3 piano lessons : 2 guitar lessons = 48 piano lessons : x guitar lessons
3/2 = 48/x
(3)(x) = (48)(2) Cross multiply
3x = 96
x = 32
What is the value of f(-1/4)?
Answer:
The x-value we need to substitute into the equation is -1/4.
When we substitute,
f(-1/4)=-8(-1/4)+4
f(-1/4)=2+4
f(-1/4)=6

if a rectangle is 8 in long and 6 in wide how many one square inch tikes are needed to cover its area
Answer:48 one square inch tiles
Step-by-step explanation:
The square has an area of (8x6)=48in^2. If we place 1 in^2 square tiles in a line 8 across (8 inches) and 6 down (6 inches), there will be 8x6 = 48 one square inch tiles.
what is this answer

6x + 4 = 3x
x = ......
Answer:
x = - 4/3
Step-by-step explanation:
6x +4 = 3x
-3x -3x
6x-3x = 3x
3x +4 = 0
-4 -4
3x = -4
_ _
3 3
x = -4/3
1. First we need to combine like terms, so we subtract 3x to both sides.
2. Then we combine the like terms
3. next move the 4 to the other side by subtracting. This will help keep the ex by itself.
4. now we divide 3 to both sides, leaving you with x = -4/3 as your answer.
1) 6x + 4 = 3x
______________
6x + 4 = 3x
6x = 3x - 4
6x = 3x - 4 - 3x
3x = -4
3x/3 = -4/3
x = - 4/3 ☑

A company has developed a training procedure to improve scores on the
SAT. Following the training, 100 high school students take the SAT. The average math score is 517, with s = 90. Assuming u = 500 for the math SAT, test
the null hypothesis. Did the training significantly improve scores (a = .05,
directional)?
Answer:
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores
Step-by-step explanationStep(i):-
Given sample mean (x⁻ ) = 517
sample standard deviation (s) =90
Mean of the Population (μ) =500
Null Hypothesis :- H₀ : (μ) =500
Alternative Hypothesis : H₁ : μ ≠ 500
Step(ii):-
Test statistic
t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }
t = \frac{517 -500}{\frac{90}{\sqrt{100} } }
t = 1.717
Level of significance
∝ = 0.05
t₀.₀₅ = 1.6604
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Conclusion:-
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores

Answer:
Sustitute the y-values into the equation.
For y=10,
2(10) + 3 (10 - 5)
20 + 3(5)
20+15
35
For y=57,
2(57) + 3 (57 - 5)
114 + 156

I need help with this very hard question that i do not understand at this moment and it is difficult for me to answer
Answer:
see below, thanks
Important concept to know:
If a line is perpendicular to another, the slope will be the opposite reciprocal of the other line's slope.
EX: y = 2x
perp line: y = -1/2x
Step-by-step explanation:
y = 3x + 2; (1, -1)
> y = 1/3x +b
> -1 = 1/3(1) + b
> y = 1/3x - 4
y = -1/5x + 1; (3, -7)
> y = 5x + b
> -7 = 5(3) + b
> y = 5x - 22
8x + 3y = 7; (-4, -8)
> 3y = -8x + 7
> y = -8/3x + 7/3
> y = 3/8x + 7/3
> -8 = 3/8(-4) + b
> y = 3/8x + 253/8
Which situation can be represented by this inequality?

Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?
Answer:
the last one.
Step-by-step explanation:
135 is smaller or equal to the number of collected songs. so, in other words the number of collected songs is greater or equal to 135. that means "at least".
the factor or r (the number of months) is 10. so, 10 songs every month. and the constant 15 is the starting value of the collection.

Answer:
ST = 164.21 m
Step-by-step explanation:
The fraction RU/UV have to be equal to RS/ST, because the triangles are similar:
190/120 = 260/ST
Multiply both sides by ST:
190ST/120 = 260
Multiply both sides by 120:
190ST = 260•120
Divide both sides by 190:
ST = 31200/190
ST = 164.21 m
Which graph passes the vertical line test?
A.
B.
C.
D.
Answer:
Graph C.
Step-by-step explanation:
The rest of the graphs fail the vertical line test. This means some inputs (x values) contain more than one output (y value).
Answer:
C
Step-by-step explanation:
If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function.
answer choices A, B, and D intersect at more than one point vertically. Therefore, C is the correct answer.
