Graph a line with a slope of 3 that goes through the point (1, 3).
X intercept and y intercept 20 POINTS
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept. We are given a slope of three so
y=3x+b, using point (1,3) we can solve for b
3=3(1)+b, 3-3=0 so b=0 then our line is
y=3x
The x intercept is when y=0 and this occurs when x=0 or the point (0,0)
The y intercept occurs when x=0, this occurs when y=0 or the point (0,0)

Tanya purchases gifts for two friends The first is a purse for $19.99, and the second is pair of shoot. Her total is $45.67 before tax, How much did she spend on the shoes?
Answer:
$25.68
Step-by-step explanation:
Cost of purse = $19.99
Cost of shoe pairs = x
Total cost = $45.67
Total cost = cost of purse + cost of shoe pairs
$45.67 = $19.99 + x
x = $45.67 - $19.99
x = $25.68
Hence, cost of shoe pair = $25.68

Which of these expressions represent solutions to the equation y3 = 64?
*Multiple answers can be selected*
Answer:
4, ∛64, -∛64
explanation:
they all mean the same thing
The expression [tex]y^{3} = 64[/tex] can be written as :[tex]y= \sqrt[3]{64}[/tex] or y= 4
The correct option is (II) and (VI)
What is cube root?
The cube root of a number is the factor that we multiply by itself three times to get that number.
We have given that:
[tex]y^{3} = 64[/tex]
we can write it as:
[tex]y= \sqrt[3]{64}[/tex]
y = [tex]\sqrt{4*4*4}[/tex]
y= 4
The answer is : [tex]y^{3} = 64[/tex]
[tex]y= \sqrt[3]{64}[/tex] or y= 4

#1.At the beginning of the season, McDonald had to remove 5 orange trees from his farm. Each of the remaining trees produced 210 oranges for a total harvest of 41790 oranges.
The equation that represents the initial amount of range trees on MacDonald farm is 41790 = 210t - 1050.
The initial amount of trees is 204
How to form an equation ?The equation that represents the initial amount of range trees on MacDonald farm can be calculated as follows;
Therefore,
number of trees presently = t - 5
Therefore,
41790 = 210(t - 5)
41790 = 210t - 1050
41790 + 1050 = 210t
42840 = 210t
t = 42840 / 210
t = 204
Therefore, the initial amount of trees is 204 .

Can a triangle be formed with the sides lengths of 7 cm, 5 cm and 12 cm?
Answer:
NO because 7+5=12
The sum must be larger (not equal to) the longest side. If it's exactly the same, there's no room to for the shorter two sides to angle up to form a triangle.

The relationship between the number of grams of carbohydrates in a loaf of bread and the number of calories the loaf contains can be modeled by the equation y approx15x-25 where the number of grams of carbohydrates, and y is the number of calories. According to the model, which statements are correct? Select all that apply.
Answer:
A and C
Step-by-step explanation:
Slope of the equation is 15, that represents calories per gram of carbohydrate increased.
What is linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
Given equation,
y = 15x - 25
x is number of grams of carbohydrates in bread
y is number of calories in bread
Comparing it with y = mx + c
slope m = 15
y - intercept c = -25
Slope represents calories per gram of carbohydrate increased.
Hence, 15 is slope of the equation, which represents calories per gram of carbohydrate increased.

If y = 5x-2 were changed to y = 3x-2how would the graph of the new
function compare with the first one?
Hi there! The answer is B. it would be less steep.
The change of the function (in this case) influences the slope of the line. Since we've modified the slope from 5 to 3/4, the line will be less steep.
