In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
a = 3
a = 8
a = 18
a = 33
Answers
Answer:
18
Step-by-step explanation:
if it adds 5 then 13+5=18
Answer:
a = 18
Step-by-step explanation:
We know from the table that our function must be y = 5x -2. We get this information by plugging in 13 = 5(3) - b and solving for b. Now that we have our function we plug in 4.
y = 5(4) -2
y = 20 - 2
y = 18

Airplane B travels at a speed that is (increasing, decreasing, 0, constant, but not 0).
Answers
Answer:
from 0 to t1
Airplane A travels at a speed that is increasing.
Airplane B travels at a speed that is constant but not 0.
from t1 to t2
Airplane A travels at a speed that is constant, but not 0
Airplane B travels at a speed that is 0.
The airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁
What is a line graph?A line graph is a graph made up of segments of straight lines that connect the depicted data points.
We have a graph for Airplane A shows the speed at which it travels as a function of time. The graph for Airplane B shows the distance it travels as a function of time.
From the graph A and B
From 0 to [tex]\rm t_1[/tex]
Airplane A is travelling at a faster and faster rate.
Airplane B moves at a steady but not zero speed.
From [tex]\rm t_1[/tex] to [tex]\rm t_2[/tex]
Airplane A moves at a constant speed, but not at zero.
Airplane B is travelling at a speed of 0.
Thus, the airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁

for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines. Write an absolute value equation that represents the minimum and maximum lengths
Answers
Answer:
lx-24l ≤ 8
Step-by-step explanation:
lx-24l ≤ 8
x ≤ 8 + 24
x ≤ 32
-----------------
-x + 24 ≤ 8
24 - 8 ≤ x
16 ≤ x
The absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.
What is absolute value?Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.
For example, |5| is 5 because it is 5 units away from 0. Also, |-5| is also 5 because -5 is 5 units from 0.
We have been given that for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines.
To determine the absolute value equation that represents the minimum and maximum lengths.
First, we need to find the difference between both solutions.
⇒ 32 - 16 = 16
Then, divide it by 2.
⇒ 16/2 = 8
⇒ 8 = |x - 32 + 8|
we could also write: 8 = |x - 32 + 8|
⇒ 8 = |x - 24|
Therefore, the absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

What is an equivalent ratio of 5:9
Answers
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
Hope this helps.
Answer:
10:18
Step-by-step explanation:
Anything really just times both sides by the same number.
For example to get to 10:18 I multiplied both sides of 5:9 by 2.
If you were to multiply 5:9 by 3 (which would 15: 27) it would still be an equivalent to 5:9.

equation B
B) 6x + 7y=1
25y = 3.25
y = 13
and X=-15
^ 5.0
Step-by-step explanation:
Answer:
• Let's first assign identifications to the equations given:
[tex]{ \rm{8x + 9y = {}^{ - }3 \: - - - \{equation \: (a) \} }} \\ { \rm{6x + 7y = 1 - - - \{equation \: (b) \}}} \\ [/tex]
• There are various methods to solve this system of equation, namely;
Graphical methodSubstitution methodElimination methodCalculus (Calculator synthetic method)1. Graphical method
→ You'll have to draw a graph, demacate it very well following the suitable scale.
→ Get values to plot from both equation (a) and equation (b).
→ Draw respective lines of each equation. The point of intersection of the lines is the answer of the values of x and y.
→ It'll be in coordinate format i.e; (x, y)
2. Substitution method
→ Lemme first consider equation (a)
[tex]{ \rm{8x + 9y = {}^{ - }3 }}[/tex]
• make x the subject of the equation (a):
[tex]{ \rm{8x = - 3 - 9y}} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8}y }} \: { \rm{- - - \{equation \: (c)}} \}[/tex]
→ Considering equation (b) next
[tex]{ \rm{6x + 7y = 1}}[/tex]
• substitute x in equation (b) with x in equation (c)
[tex]{ \rm{6( \frac{ - 3}{8} - \frac{9}{8}y ) + 7y = 1 }} \\ \\ { \rm{ - \frac{9}{4} - \frac{27}{4} y + 7y = 1}} \\ \\ { \rm{ \frac{1}{4} y = \frac{13}{4} }} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]
• then find x using equation (c)
[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y }} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8} (13)}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]
3. Elimination method:
→ Here, we have to align the equations so that if we use addition or subtraction operations we remain with one term giving us zero [ eliminated ]
→ Multiply equation (a) by 6 and multiply equation (b) by 8. In order to eliminate x
→ Then we subtract equation (a) with equation (b)
[tex]{ \underline{ \rm{ - \binom{6(8x + 9y = - 3)}{8(6x + 7y = 1)} }}} \\ { \rm{ 0x \: - 2y = - 26 }} \\ \\ { \rm{ - 2y = - 26}} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]
• find x using equation (c)
[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]
4. Calculator synthetic method:
→ To use this method, you must have a scientific calculator.

What number is 12 more than 1/3 of itself?
Answers
Answer:
18
Step-by-step explanation:
Let the number be x.
1/3 of itself is 1/3 x or x/3.
x = x/3 + 12
3x/3 - x/3 = 12
2x/3 = 12
3/2 * 2x/3 = 3/2 * 12
x = 18
Answer: 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The number is 12 more than 1/3 of itself.
Let the number be 'x'. Then the equation is written as,
x = x/3 + 12
Simplify the equation, then the value of 'x' will be calculated as,
x - x/3 = 12
3x - x = 36
2x = 36
x = 36/2
x = 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.
