Answer:
4
Step-by-step explanation:
The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.
Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.
Solving that equation will give you b=-7
That means the y-intercept is -7.
The equation would then be y=4x-7

LA
Maths
Answers
Answer:
x = 17
Step-by-step explanation:
Here, we want to find the value of x
mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
So we have;
(16 + 14 + x + 23 + 20)/5 = 18
73 + x = 5(18)
73 + x = 90
x = 90-73
x = 17

THREE NUMBERS BEHIND THE DECIMAL PT
Answers
Answer:
Step-by-step explanation:
4). This is an exponential function.
5). Let the equation of this function is,
f(x) = a(b)ˣ
Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,
For (-1, 4),
4 = a(b)⁻¹
4 = [tex]\frac{a}{b}[/tex] --------(1)
For (0, 6),
6 = a(b)⁰
a = 6
From equation (1),
4 = [tex]\frac{6}{b}[/tex]
b = [tex]\frac{6}{4}[/tex] = 1.5
Therefore, equation of the function will be,
f(x) = 6(1.5)ˣ
6). Now the value of f(-4) will be,
f(-4) = 6(1.5)⁻⁴
= 1.185

Answers
Answer:
$330,000
Step-by-step explanation:
The selling price per unit is $15
The variable cost per unit is $5
Units sold is $33,000
The contribution margin can be calculated as follows
(15-5)×33000
= 10 × 33000
= 330,000
Hence the contribution margin is $330,000

Write a second equation whose graph goes through (0,1) so the system has no solutions.
Answers
Answer:
y = 5x + 1
Step-by-step explanation:
Hello There!
Equations that have no solutions are parallel
So the line we are going to create an equation for has the same slope as the line drawn
To find the slope we do change in y divided by change in x
as y goes 5 x goes up 1
so the slope is 5/1 or 5
The requirements for the equation is it has to go through the points (0,1)
The ordered pair listed is the y intercept so the equation would be
y = 5x + 1
Adult movie tickets cost $8 each. Children pay $5 for a ticket. For one movie, 90 total tickets were sold for a total of $525. Which system of equations can be used to find the number of each type of ticket, adult, a, and children, c, that were sold?
A. a + c = 90 8a + 5c = 525
B. a + c = 525 8a + 5c = 90
C. a + c = 90 5a + 8C = 525
D. a + c = 525 5a + 8C = 90
Answers
Answer: A
Step-by-step explanation:
I had this question on my test yesterday lol
The system of equation will be ". a + c = 90 8a + 5c = 525"
Let the number of adults tickets be represented by a
Let the number of children tickets be represented by c.
Since 90 total tickets were sold, this can be represented by the equation:
a + c = 90
Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:
8a + 5c = 525
Therefore, the correct option is A.

If x + y = 12 and x = 2y, then x=
Answers
The value of x is equal to 8.
Given the following equation;
[tex]x + y = 12[/tex] .....equation 1
[tex]x = 2y[/tex] .....equation 2
To find the value of x, we would solve the system of equations by using the substitution method to determine the value of y;
Substituting eqn 2 into eqn 1, we have;
[tex]2y + y = 12[/tex]
[tex]3y = 12\\\\y = \frac{12}{3}[/tex]
y = 4
Next, we would solve for the value of x;
From equation 2;
[tex]x = 2y\\\\x = 2(4)[/tex]
x = 8
Therefore, the value of x is equal to 8.

the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)
Answers
Answer:
AED 210
Step-by-step explanation:
If the cost of 7 toys is AED 294, this is written as;
7 toys = AED 294
To get the cost of 5 toys, this is written as;
5 toys = x
Divide both expressions
7/5 = 294/x
Cross multiply
7x = 5 * 294
7x = 1470
x = 1470/7
x = 210
Hence the cost of 5 toys is AED 210

Sam and Ella were running in a race. Sam ran ⅞ of a mile and Ella ran 5/10 of a mile. At the end of the race they wanted to compare how far they ran. Ella said they could compare the fractions by comparing each fraction to ½. Show how Ella could compare 5/10 and ⅞ to ½ . Then explain who ran further and how you know.
Answers
Answer:
ELLA
Step-by-step explanation:
Given that :
Distance covered by Ella = 5/10
Distance covered by Sam = 7/8
Comparing each distance to 1/2
Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5
Sam = 7/8 = 0.875 ; comparing with 1/2
0.875 > 0.5
Given
Sam ran farther Than ELLA
Because 0.875 > 1/2
0.875 - 0. 5 = 0.375
