5. Evaluate f(x) = 2x – 7 at the given value. f(4)=?
Answer:
f(5) = 14
Step-by-step explanation:
Just replace the variable "x" with "5":
f(5) = 2×5 + 4 = 14
Answer:
1
Step-by-step explanation:
Since the value of x is 4 ( because four is in the position of x) you would plug in 4 into he equation.
2(4) = 8
Then 8 - 7 = 1
F(4) is 1
Therefore, your final answer is 1.
Bao is taking a multiple choice test with a total of 100 points available. Each question
is worth exactly 2 points. What would be Bao's test score (out of 100) if she got 8
questions wrong? What would be her score if she got x questions wrong?
Answer:
84
Step-by-step explanation:
100-point test = 50 questions which are worth 2-points each.
(50 x 2 = 100)
If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)
100 - 16 = 84
To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.
25 Patricia bought 5 apples and 7 bananas for $12.65. Jose bought 10 apples and 8 bananas for $18.10 at the same grocery store. What is the cost of one apple?
Answer:
Apple cost $0.85
Banana cost $1.2
Step-by-step explanation:
Given data
let the number of apples be x
and the number of bananas be y
Patricia bought 5 apples and 7 bananas for $12.65
5x+7y= 12.65----------1
Jose bought 10 apples and 8 bananas for $18.10
10x+8y= 18.10-----------2
solve 1 and 2 above
5x+7y= 12.65 X 2
10x+8y= 18.10 X 1
10x+14y= 25.3
- 10x+8y= 18.10
6y= 7.2
y= 7.2/6
y= 1.2
put y= 1.2 in 1
5x+7(1.2)= 12.65
5x+ 8.4= 12.65
5x= 12.65- 8.4
5x= 4.25
x= 4.25/5
x= 0.85
Hence each apple cost $0.85
Banana cost $1.2

FIND BC
round to the nearest HUNDREDTH
Answer:
CB = 30.15
Step-by-step explanation:
180-58-93 = 29 degrees for angle B
draw a line perpendicular to BC down to point A, lets call the perpendicular point D.
now you've got 2 similar, smaller triangles
angle A is split into two angles, 29 degrees above and 58 degrees below.
sin 29 =CD/16
CD = 7.75
cos 29 = AD/16
AD = 14
tan 58 =DB/AD = DB/14
DB = 22.40
CD + DB = 7.75 + 22.40 = 30.15

you have to add up all of the sides. 3/4 plus 1/4 equals 1. 1 plus 1/8 equals 1 1/8. Hope I helped you : )
Linda is paid double her normal hourly rate for each hour she works over 40 hours in a week. Last
week she worked 52 hours and earned $544. What is her hourly pay?
Answer:
her hourly pay is £8.50
Step-by-step explanation:
h= hourly pay
n = number of hours worked over 40 hours in a week
week pay = 40h + (n x 2 x h)
544 = 40h + 2nh
52 - 40 = 12, so n = 12
544 = 40h + 2 x 12 x h
544 = 40h + 24h
544 = 64h
544/64 = 8.5 h=8.5 (£8.50)
just to check:
£8.50 x 40 = £340
£8.50 x 2 x 12 = 204
340 + 204 = 544 yayy the answer is correct
hope this helps x

Eigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1.
Answer: 20/3
Step-by-step explanation:
To write 6 2/3 as a fraction greater than 1, we simply have to convert it from a mixed fraction to an improper fraction. This will be:
6 2/3 = [(6 × 3) + 2]/3
= (18 + 2)/3
= 20/3
Therefore, the answer is 20/3.

What is the sixth number in the Fibonacci sequence with the first two numbers 1 and 4?
Answer:
23
Step-by-step explanation:
1 + 4 = 5 so we get 1 4 5
then 4+5 = 9, 1 4 5 9
5+9 = 14, 1 4 5 9 14
9+14 = 23, so
1 4 5 9 14 23
23 is the 6th number in this sequence
The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.
Given :
Fibonacci sequence with the first two numbers 1 and 4.
The following steps can be used to determine the sixth number in the Fibonacci sequence:
Step 1 - If the first two numbers in the Fibonacci sequence is 1 and 4 then the third number is:
= 1 + 4
= 5
Step 2 - The Fourth number in the Fibonacci sequence is:
= 4 + 5
= 9
Step 3 - The Fifth number in the Fibonacci sequence is:
= 5 + 9
= 14
Step 4 - The Sixth number in the Fibonacci sequence is:
= 9 + 14
= 23
So, the sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23.

Luis, que recibe $200 mensuales desde hace un año, el mes pasado le dijo a su papá que le aumentará su mesada; el monto deseado será suficiente si tres medios de la cantidad deseada más 4100 son mayores o iguales a $700. ¿Cuánto de más quiere recibir Luis?
Answer:
Luis quiere recibir 200$ de más por mes.
Step-by-step explanation:
Para podr calcular esto, necesitamos escribir la desigualdad dada, y para ello debemos transformar el lenguaje a lenguaje algebraico.
tres medios de la cantidad deseada: 3/2 x
mas 4100 (en este caso debería ser $100, y fue un error de tipeo): + 100
son mayor o igual a $700: ≥ 700
Inecuación: 3/2 x + 100 ≥ 700
Ahora solo nos queda resolver el valor de x de esta inecuación. El resultado nos dirá cuanto quiere recibir al mes, por lo que la resta de esta cantidad con la cantidad que recibía antes nos dirá cuanto de más desea recibir:
3/2 x + 100 ≥ 700
3/2 x ≥ 700 - 100
3/2 x ≥ 600
3x ≥ 600 * 2
x ≥ 1200 / 3
x ≥ 400
Por tanto, Luis desea recibir al mes $400, lo que se traduce en que quiere recibir de más
400 - 200 = 200
Luis desea recibir de mas $200.

Tyrone ran the 100-meter race 3 times. His fastest time was 10.84 seconds. His slowest time was 13.52 seconds. If Tyrone's average time was 12.0 seconds, what was his time for the third race? *
Answer:
The third time = 11.64 seconds
Step-by-step explanation:
Let the average time be x
The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:
Average = (10.84 + 13.52 + x) ÷ 3 = 12.0
[tex]\frac{10.84\ + 13.52\ + x}{3}= 12.0\\\frac{24.36\ +\ x}{3} = 12.0\\cross-multiplying\\24.36\ +\ x = 3 \times 12.0\\24.36\ +\ x = 36\\x = 36 - 24.36\\x = 11.64\ seconds[/tex]

I need this question quick lol
Answer:
hey
b = 2
Step-by-step explanation:
Let's solve your equation step-by-step.
9+4b=17
Step 1: Simplify both sides of the equation.

reflection and translation.
Given:
The different transformation in the options.
To find:
The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.
Solution:
In option 1,
[tex](x,y)\to (y,x)[/tex]
It represents reflection across the line y=x.
In option 2,
[tex](x,y)\to (x,-y)[/tex]
It represents reflection across the x-axis.
In option 3,
[tex](x,y)\to (4x,4y)[/tex]
It represents dilation by scale factor 4 and the center of dilation is at origin.
In option 4,
[tex](x,y)\to (x+2,y-5)[/tex]
It represents translation 2 units right and 5 units down.
We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.
So, the perimeter of the figure and its image are same in the case of reflection and translation.
But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.
Therefore, the correct option is 3.
