Answer:
x=3, x=[tex]-\frac{5}{2}[/tex]
Step-by-step explanation:
2x^2-x-15=0
2 times -15 equals -30, so plug in 5x and -6x for -x
2x^2-6x+5x-15 factor,
2x(x-3) 5(x-3)
x-3=0 2x-5=0
x=3 x= -5/2

-1/2 = m -7/4
solve for m
Answers
Answer:
[tex]\boxed {m = \frac{5}{4}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]m[/tex]:
[tex]-\frac{1}{2} = m - \frac{7}{4}[/tex]
-Switch sides:
[tex]m - \frac{7}{4} = -\frac{1}{2}[/tex]
-Add both sides by [tex]\frac{7}{4}[/tex] and the least common multiple of both [tex]2[/tex] and [tex]4[/tex] is [tex]4[/tex]. So, convert [tex]-\frac{1}{2}[/tex] to a fraction with denominator [tex]4[/tex]:
[tex]m - \frac{7}{4} + \frac{7}{4} = -\frac{1}{2} + \frac{7}{4}[/tex]
[tex]m = -\frac{2}{4} + \frac{7}{4}[/tex]
-Since both [tex]-\frac{2}{4}[/tex] and [tex]\frac{7}{4}[/tex] have the same denominator, then you would add the numerators:
[tex]m = \frac{-2 + 7}{4}[/tex]
[tex]\boxed {m = \frac{5}{4}}[/tex]
Therefore, the value of [tex]m[/tex] is [tex]\frac{5}{4}[/tex].

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

3) 10^x = 1 = 10^0
x = 0
answer:
okay so i did it and i got these answers
- y = 20
- 4^8
- x = 0
step-by-step explanation:
my work
- p^3 × p^5 = p^-12 × p^y then 3 + 5 = -12 + y so: 20 = y
64 × 4^5 = 4^3 × 4^5 = 4^(3+5) so: its 4 over 8
10^x = 1 = 10^0 so: its 0

Giovanni went to the Lowe’s looking for supplies. He bought three pounds of cement for $27.75 per pound. A plant for $12.58. He paid $8.99 is sales taxes. How much did he pay in total at Lowe’s?
Answers
Step-by-step explanation:
Hey there! Let's break this answer down.
1. If he bough 3 pounds of cement for $27.75 each, that 3x27.75, which is $83.25. So he spent $83.25 on cement.
2. Next, add $12.58 for the cost of the plant to $83.25, which $95.83.
3. Finally, he paid $8.99 for the sales tax. When adding that to $95.83, we get $104.82.
So, his total was $104.82.
Have a great day!
Answer:
104.82
1Step-by-step explanation:
27.75 times 3 equals 83.25 plus 12.58 equals 95.83 then add 8.99 which is $104.92

The given equation can be rearranged to equate both side of the equation and thus we can get equivalent on both side as 6 (2y-3) = 6 (2y-3). Therefore, y can have any values from 0.
What are algebraic equations?Algebraic equations are expression used to represent the relation between two values by some letters or alphabets whose values are not specified in the equation.
In general, the letters x and y are used in the algebraic equations. They can linear or non-linear equation. By rearranging this equations we can determine the values of x and y.
Given the expression 12 y - 18 = 6 (2y - 3). From the left hand side, divide the part 12 y - 18 by 6. Thus we obtain the expression equivalent to the right hand side as 6 (2y - 3).
Therefore, 6 (2y - 3) = 6 (2y - 3). Which means both sides are equal and have equal value of y. means y can have any values from zero since all the terms including y is zero both side.
Thus, giving any value to y will always remains the same equation.
