What is the y-intercept of the line?
Answer:
34
Step-by-step explanation:
We start by working out the slope. The slope is change in y over change in x, so (66-58)/(-56)-(-42) is the slope here. 66-58 is 8, and -56-(-42) is -14. -8/14=-4/7. The equation of a line in slope-intercept form is y=mx+b where b is the y intercept and m is the slope. Since the slope is -4/7, then y=-4/7x+b. We then insert any x and y pair into this equation and solve for b, the y intercept to get it. (We can do ANY pair) So, 50=(-4/7)(-28)+b.
: 50=16+b
: 50-16=b
: 34=b
So, in conclusion, the y intercept is 34. Hope this helps!

Find the slope and the y−intercept of the line in the graph.
The slope is .
The y−intercept is .
Please be very specific
Very confused
Help please??
Answer:
Step-by-step explanation:
Using the slope-intercept form:
y=mx+bIn the equation y=mx+b, b is the coordinate on the y-axis where the graph crosses the y-axis and m denotes the slope of the line. The x and y represents all the (x, y) order pairs that graph points.
y=3x+4Substitute x for 0 to find the pair (0, Y). y=3(0)+4 Since 3 times 0 is 0, y will equal 4.
So put 4 under the 0.y=3(-1)+4 ⇒-1,1 y=1
y=3(0)+4 ⇒0,4 y=4
y=3(1)+4 ⇒ 1, 7 y=7
y=3(2)+4 ⇒ 2, 10 y=10
y=3(3)+4 ⇒ 3, 13 y=13

How can I find a rule in a math question
Answer:
Step-by-step explanation:
How to write the rule of a function given the table of values. To write the rule of a function from the table is somehow tricky but can be made easier by having prior knowledge of the type of function. If the function is a linear function, plugging any two sets of values from the table into the equation y = ax + b, where a and b are constants to be found and x, y are values taken from the table. Solving the two equations obtained simultaneously gives the values of a and b and hence the required rule.
Similarly, if the function is a quadratic equation, plugging any three sets of values from the table into the equation y = ax^2 + bx + c, where a, b, c are constants to be found and x, y are values taken from the table. Solving the three equations obtained simultaneously gives the values of a, b and c and hence the required rule. For tables with no prior knowledge of the type of function, a series of trial and error will lead us to the solution of the problem.
7x-12y=180 7x=84
i need someone to explain step by step
Answer:
x=12,y=-8
Step-by-step explanation:
7x=84
x=84/7=12
12y=7x-180=7*12-180=84-180=-96
y=-96/12=-8
The solution of 7x-12y=180 is x = 12 and y =-8.
What is an equation?An equation is made up of two algebraic expressions with the same value and the sign "=" in between.
Given, the equation;
7x-12y=180 {equation 1}
And 7x = 84
x = 84/7
x = 12
Substitute the value of x to the equation 1,
7(12) - 12y = 180
12y = 84 - 180
y = -96/12
y = -8
Therefore, x = 12 and y = -8 is the solution.

A SQUARE RECTANGULAR PRISM (BASE IS A SQUARE) HAS A
VOLUME OF 38 CU. IN. THE HEIGHT IS 10 LESS THAN THE AREA
OF THE BASE. WHAT IS THE HEIGHT? NO UNITS.
The height of the prism [tex]\approx 2.9[/tex]
The whole volume of the prism is
[tex]\text{Volume} = \text{Area of base}\times \text{Height}[/tex]
Here, the volume is 38 cu. in.
From the question, the area and the height are related as follows;
[tex]\text{Height} = \text{Area} - 10 \implies \text{Height + 10} =\text{Area}[/tex]
Substituting this into the formula for the volume, we get
[tex]\text{Volume}=(\text{Height} +10)\times \text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}-38=0[/tex]
If the above quadratic equation is solved for the height, we get
[tex]\text{Height}\approx 2.9[/tex]
(We can't take the other solution since height has to be greater than zero)

The first term is 5
Is the sequence arithmetic?
Yes because (5 -7 = -2) (-2 - 7 = -9)
Find the common difference d:
The common difference is -7
Find the general term an:
[tex]a_{n}[/tex] = (first term) + ((nth term) -1) · (common difference)
[tex]a_{n}[/tex] = 5 + (n - 1) · (-7)
Find the 20th term:
[tex]a_{20}[/tex] = 5 + (20 - 1) · (-7)
= -128
Find the sum of the first 50 terms:
[tex]a_{50}[/tex] = 5 + (50 - 1) · (-7)
= -338

Enlarge triangle ABC by scale factor -2, centre (4,2)
Answer:
see attached
Step-by-step explanation:
The scale factor of -2 means each point on the preimage will be reflected across the center of dilation a distance twice its distance to that center.
For example, point B is 2 units right and 1 unit down from the center of dilation. Its image will be 4 units left and 2 units up from the center of dilation, so will have coordinates B'(0,4).
C is 1 unit right of B, so C' will be 2 units left of B', at C'(-2, 4).
A is 4 right and 1 up from the center, so A' will be 8 left and 2 down from the center, at A'(-4, 0).

What is (2x-7y)^2 simplified
Answer:
4x² - 28xy + 49y²
Step-by-step explanation:
(2x - 7y)²
= (2x - 7yy)(2x - 7y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x - 7y) - 7y(2x - 7y) ← distribute parenthesis
= 4x² - 14xy - 14xy + 49y² ← collect like terms
