Step-by-step explanation:
y = ax +b
2 = 0a+ b => b = 2
4 = -2a + b
4 = -2a +2
2a = 2-4
2a = -2
a = -1
so, y = -x + 2
What is the value of x + y?

Answer:
6) a) 69 b) 97 c)86 d)71
7) A.
Step-by-step explanation:
6)
a) -1-[9(-8)]-2 = -1 - (-72) -2
= -3 + 72 = 69
b) 81 + 4² = 81 + 16
= 97
c)12×7 + 6÷3 =(12×7)+(6÷3)
= 84 + 2
=86
d)74 + 9 ÷ -3 = 74 + (9÷ -3)
= 74 - 3
= 71

Use the distributive property to multiply x^2−4 by x^2+3x-5 and combine like terms.
Draw the image of quadrilateral ABCD under a translation by 2 units to the right and 5 units down.
Answer:
Answer:
That is correct
Step-by-step explanation:
Change the following mixed expressions to fractions and then simplify the complex fractions.
Answer:
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]
Step-by-step explanation:
One is given the following expression:
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
Now simplify this expression, then cancel common terms in the numerator and denominator,
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

I WILL MARK AS BRAINLIEST! Write an Equation that represents the points in the table
Answer:
y = 3x + 5
Step-by-step explanation:
Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).
Substitute the information for the variables in the slope-intercept form equation.
y = mx + b
m = slopeb = y-intercept valueAnswer:
y=3x +5

A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
Practice:
What is the square root of 49?
What is the square root of 100?
What is the square root of 625?
Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.
Answer:
72
Step-by-step explanation:
There are 20 students in the class. They break up into groups of 5 for an art project. Choose the equation that shows how many groups there are.
20 x 5 = ?
20 x 4 = ?
20 divided by 4 = ?
20 divided by 5 = ?
