Answer:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where:
L = length and W = width
The rectangle shown has a perimeter of 54 cm
Its length is 3 more than twice its width.
2L + 2W = 54 .... Equation 1
"length is 3 more than twice its width."
L = 2W + 3.....Equation 2
Substituting 2W + 3 for L
We have:
2L + 2W = 54 .... Equation 1
2(2W + 3) + 2W = 54
4W + 6 + 2W = 54
6W = 54 - 6
6W = 48
W = 48/6
W = 8cm
L = 2W + 3.....Equation 2
L = 2(8) + 3
L = 16 + 3
L = 19 cm
Therefore:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.
Which of the following can be used to prove that triangle ABC is congruent to triangle DEF?
Answer:
SAS congruence theorem
Step-by-step explanation:
since we are given the two congruent sides and the right angle. We know all right angles are congruent and the right angle is an angle that is between the two sides which is why it is SAS. hope this helps :))

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
9/70
Step-by-step explanation:
Mathematically;
Average rate of change on an interval [a,b] is;
f(b) - f(a)/b-a
f(0) = -3/5
f(3) = -3/14
a = 0
b = 3
Making the substitution, we have
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70
What is the reciprocal of 2 4/5 ?
Answer:
5/14
Step-by-step explanation:
Answer: 14/5.
Step-by-step explanation;
The reciprocal of 2-4/5 can be found by multiplying the whole number (2) by the denominator (5) and then add the amount to the numerator (4), this will give you fourteen, which is now the numerator of the reciprocal fraction. The denominator will stay the same, so the reciprocal of 2-4/5 is 14/5.
Solve Each Equation
5. -8(5+4x)=-232
6. -84=4(4r+7)
Step-by-step explanation:
5.[tex] - 8(5 + 4x) = - 232[/tex]
[tex] - 40 - 32x = - 232 \\ - 32x = - 232 + 40 \\ - 32x = - 192 \\ \frac{ - 32x}{ - 32} = \frac{ - 192}{ - 32} \\ \\ \huge x = 6[/tex]
6.[tex] - 84 = 4(4r + 7) \\ - 84 = 16r + 28 \\ 16r = - 84 - 28 \\ 16r = - 112 \\ \frac{16r}{16} = - \frac{112}{16} \\ \\ \huge r = 7[/tex]

Write a linear function f with the values f(−1)=5 and f(3)=4.
Answer:
1 Expert Answer When they say f(0) = -5 they mean the point (0, -5) is on the line. When they say f(3) = 4 they mean the point (3, 4) is on the line. In y = mx + b form, we would have f(x) = 3x - 5.
Step-by-step explanation:
The function is to be determined from the given points.
The linear function is [tex]f(x)=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]
The given values are
[tex]f(-1)=5[/tex]
[tex]f(3)=4[/tex]
The ordered pairs are [tex](-1,5),(3,4)[/tex]
The equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\Rightarrow y-5=\dfrac{4-5}{3-(-1)}(x-(-1))\\\Rightarrow y-5=-\dfrac{1}{4}(x+1)\\\Rightarrow y-5=-\dfrac{1}{4}x-\dfrac{1}{4}\\\Rightarrow y=-\dfrac{1}{4}x-\dfrac{1}{4}+5\\\Rightarrow y=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

Can anybody help me with this plzzz‼️
(If answer is correct i will cashapp you $6)
Step-by-step explanation:
h(x) = 3. g(x) + 5
x= -1 h(x) = 3×8 + 5= 29
x= 0h(x) = 3×5 + 5= 20
x= 2 h(x) = 3×1 + 5= 8
x= 5 h(x) = 3×-5 + 5= -10
[tex]h(x) = 3*g(x)+5[/tex]
When x = -1.
Substitute x = -1 in both h(x) and g(x). | As shown in the table, when x = -1, g(x) = 8 |
h(-1) = 3*8+5 = 24+5 = 29
h(0) = 3*5+5 = 15+5 = 20
h(2) = 3*1+5 = 3+5 = 8
h(5) = 3*(-5)+5 = -15+5 = -10

Answer:
y = 65x + 250
Step-by-step explanation:
Let the linear equation representing the relation between total pay and number of computers sold be,
y = mx + c
Here, m = commission on every computer sold = slope of the linear function
c = weekly salary
y = total pay
x = number of computer sold each week
Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table attached,
Slope of the line passing through (4, 510) and (6, 640),
m = [tex]\frac{640-510}{6-4}[/tex]
= 65
Equation of the line will be,
y = 65x + c
Since, this line passes through (4, 510),
510 = 65(4) + c
c = 510 - 260
c = 250
Therefore, equation of the line will be,
y = 65x + 250
While practicing her foul kicks for soccer, Louisa made 85% of her shots. If she made 51 shots, how many shots did she kick in total?
Answer:
the exact answer is 58.65
Step-by-step explanation:
since she made 85% of her shots, that means in total from her 51 shots, she made 115% more than 51 (you add 15% to 100%). The 15% is from the difference of 100% and 85%. You then change 115% to fraction form (1.15) and multiply it by the amount of shots made, getting you 58.65. Since you can't make a fraction in terms of a real life scenario like this, you prob need to round or something. Diff teachers want diff things

find the mean median and mode of the data set :15,11,14,10,12,15,15
Answer:
Mean = 13.14, Median = 14, Mode = 15
Step-by-step explanation:
The mean is the numbers added together divided by the number of numbers
15 + 11 + 14 + 10 + 12 + 15 + 15 = 92
92 / 7 = About 13.14
The median is the middle of the numbers ordered from least to greatest
10 11 12 14 15 15 15
14 is in the middle so that is the median.
The mode is the number showing up the most.
15 shows up 3 times so it is the mode.

Write a linear function to describe the sequence. Explain your function. The first 5 terms of an arithmetic sequence are shown. 5, 2, –1, –4, –7 Write a linear function to describe the sequence. Explain your function.
Answer:
The linear function is;
Tn-1 = Tn + 3
What this mean is that to get the term before the present term, we add 3 to the present term
Step-by-step explanation:
Here, we want to write a liner function to describe the function
As we can see from the numbers listed,
the next term is simply obtained by deducting 3 from the previous term
We can write this as:
Tn-1 = Tn + 3
Where Tn is the next term and Tn-1 is the previous term
What the function is saying is that to get the term before the present term, we add 3 to the present term

Step-by-step explanation:
Direct Proportion
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is the constant of proportionality.
Solving for y:
y=kx
