Answer:
One solution, as there is only one intersection between these two lines.
x = 2, and y = 1 (point of interesection (2, 1) )
y = 2x-3
y = -x + 3
first step is to substitute the y of one equation into the other and solve for x.
- x + 3 = 2x - 3
___________
+x. +x
_____________
3 = 3x-3
_____________
+3 +3
____________
6 = 3x
_____________
÷3 ÷3
_______________
2 = x
______________
x = 2
_______________
We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.
x = 2 -> y = 2(x) - 3
2(2) - 3 = 4 - 3 = 1
y = 1
____________
x = 2 -> y = -(x) + 3
-(2) + 3 = -2 + 3 = 1
y = 1
How do you graph y=1/2x -2
Answer:
Graphing y=1/2x-2 will look like this on the graph
Answer:
Step-by-step explanation:
the 1/2 is a gradient so you go up 1 for every 2 to the right
the -2 is the Y intercept so you start graphing the gradient from -2 on the Y axis

What is the minimum angle of rotation lin degrees that will carry the six-sided star onto itself?
What’s the degree
Answer:
120 degrees
Step-by-step explanation:
If it's a 6 sided star, that means that it will be divided into 3 parts (think about how a normal 5-point star has 10 sides). That means that we divide 360 (total number of degrees in a full rotation) by 3 (number of sections) = 120

1. Tara already knew 4 appetizer recipes before starting culinary school, and she will learn 3 new appetizer
recipes during each week of school. Write an equation that shows the relationship between the number of
weeks and the number of appetizer recipes.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the number of appetizer recipes she will learn
during school
(c) Solve your linear equation to determine the number of recipes that Tara will know after 18 weeks in
school
(d) Explain your answer to Part 1c.
Answer:
Answer:
(a) The dependent variable = The total number of new appetizer recipe Tara knows = y
The dependent variable = The total number of new appetizer recipe Tara learns = A
The independent variable = Number of weeks she is in school = x
(b) A = 3 × x
(c) 58 recipes
(d) The total number of recipes Tara knows after 18 weeks = The new recipes she learns during the 18 weeks of school + The number of recipes Tara already knew
Step-by-step explanation:
The given parameters are;
The number of appetizer recipes Tara already knew = 4
The number of new appetizer recipe she will learn each week of school = 3
(a) The dependent variable = The total number of new appetizer recipe Tara knows = y
The dependent variable = The total number of new appetizer recipe Tara learns = A
The independent variable = Number of weeks she is in school = x
The added constant term = The number of appetizer recipes Tara already knew = 4
(b) The equation for the number of appetizer, A, she will learn during school is give as follows;
The number of new appetizer recipe Tara learns in school = 3 × Number of weeks she is in school +
A = 3 × x
(c) The total number of recipes, y, that Tara will knows after 18 weeks in school is therefore;
y = A(18) + The number of appetizer recipes Tara already knew
A(18) = 3 × 18 = 54
y = 54 + 4 = 58 recipes
(d) The total number of recipes Tara knows after 18 weeks is the sum of the new recipes she learns during the 18 weeks of school and the number of recipes Tara already knew.

For the equation 4(2x-3)-(mx+5)=5x+b to be an identity, which of the following must be true about the constants m and b? Show your work
(1) m = 3 and b = -7
(2) m = 8 and b = 17
(3) m = -3 and b = -15
(4) m = 3 and b = 17
Given:
The equation is
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
To find:
The values of m and b.
Solution:
We have,
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
Using distributive property, we get
[tex]8x-12-mx-5=5x+b[/tex]
On combining like terms, we get
[tex](8-m)x+(-12-5)=5x+b[/tex]
[tex](8-m)x-17=5x+b[/tex]
On comparing both sides, we get
[tex](8-m)=5[/tex]
[tex]-m=5-8[/tex]
[tex]-m=-3[/tex]
[tex]m=3[/tex]
And,
[tex]b=-17[/tex]
Therefore, m = 3 and b = 17.
Note: All options are incorrect.

9) There are six girls and 12 boys in Ms. Jeffry's environmental club. She wants to divide the students into groups with the same number of boys and the same number of girls in each group. What is the maximum number of groups she can make? *
No . of girls in Ms. Jeffry's environmental club = 6
No . of boys in Ms. Jeffry's environmental club = 12
To find the maximum number of groups she can make , we have to find the highest common factor ( HCF ) of the number of boys and girls in her club .
Factors of 6 = 1 , 2 , 3 and 6
Factors of 12 = 2 , 3 , 4 , 6 and 12
Hence the highest common factor of 6 and 12 are 6 .
Therefore , the maximum number of groups Ms . Jeffry can make where the number of girls and boys are same are 6 .

What value should go in the empty boxes to complete the calculation for finding the product of 0.59 × 0.37? Both numbers are the same; however, only input the number one time in your answer. 0.59 times 0.37 gives two unknown partial products. The first product is 413. The second product is 1 thousands, an unknown value in the hundreds place, an unknown value in the tens, and 0 ones. These products are being added. Numerical Answers Expected! Answer for Blank 1:
Answer:
1 7 _7 0
Step-by-step explanation:
From this Given information:
We are to find the product of:
0.59
× 0.37
However, the first product is given as 413;
Also, the second product is 1 thousand, an unknown value in the hundreds place, an unknown value in the tens, and 0 ones.
Mathematically; i.e. 1 __ __ 0
i.e.
0.59
× 0.37
4 1 3
+ 1 __ __ 0
So, to work out the unknown; we look for the multiplication of:
0.59
× 0.37
This is calculated as:
0.59
× 0.37
4 1 3
1 7 7
0 0 0
1 1 8 3
Thus:
1183 - 413 = 770
i.e
the unknown value in the hundreds place is highlighted in bold format = 700
the unknown value in the tens place is highlighted in bold format = 70
A triangle has angle measures 23° and 35°. What is the measure of the third angle
The angles in a triangle add up to 180 degrees, so the third angle must be 180 - 23 - 35 ---> 157 - 35 --> 122.
122 degrees.
Hope this helps!
The measure of the third angle is 122° and the triangle is an obtuse angle triangle.
What is a triangle?A triangle is a 2D figure joined by the lines of three non-colinear points.
There are three types of triangles they are:- Equilateral triangle, Isosceles triangle, and Scalene triangle.
We know that sum of all the interior angles of a triangle is 180°.
Given two angles which measure 23° and 35° and assuming the third angle to be x°.
∴ 23° + 35° + x° = 180°.
58° + x° = 180°.
x = 180° - 58°.
x = 122°.
We can conclude that the triangle is an obtuse angle triangle.
