If 6x+3y=−1 and
5x+y=8 are true equations, what would be the value of
−x−2y?
Answer: 9
x = 2.778
y = -5.889
-x -2y
= -2.778 - 2(-5.889)
= 9

need explanation to pls
Answer:
[tex](4 \div \frac{1}{2}) = 4 \times 2 = \boxed 8✓\\[/tex]
8 is the right answer.Answer:
8 is the answer
Step-by-step explanation:
4=whole number
1=numerator
2=denominator
when we do reciprocal it became
4x2/1=8/1
so the answer is 8/1
decimal from 8/1=8
8/1 is an improper fraction and be written as 8

THANK YOU
if 10 calculator cost £120 how much does 8 cost?
Answer:
1 calculator cost £12
120 divided by 10 = 12
now 8 x 12 = £96
8 calculators cost £96
Step-by-step explanation:
Answer:
£96
Step-by-step explanation:
If you have 10 calculators which cost £120, you just need to divide 120 by 10 which will give you 12. Since 8 is only 2 away from 10, you just need to times 12 by 2, giving you 24, then take that away from 10! Hope this helped!

Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.
Answer:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Step-by-step explanation:
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39
You're answer is -39+5(-41)=244
Please help it’s either C or A I’m pretty sure! Please help :(

how do you find the axis of symmetry?
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Answer:
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48Step-by-step explanation:
Let the larger number be = xLet the smaller number be = yAs the larger number is twelve more than a smaller, so
x = y + 12
As the sum of larger and smaller numbers is 84, so
x + y = 84
now substituting x = y + 12 in th equation x + y = 84
x + y = 84
(y + 12) + y = 84
2y + 12 = 84
subtract 12 from both sides
2y + 12 - 12 = 84 - 12
2y = 72
divide both sides by 2
2y/2 = 72/2
y = 36
Thus,
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48The blue dot is at what value on the number line?

What is the y-intercept of y=-4/3x+4?
A) (0,4)
B) (4,0)
C) (0.-4)
D) (-4,0)
PLEASE HELP ME
Answer:
A. (0,4)
Step-by-step explanation:
You can calculate the y intercept when x = 0.
Substitute 0 for x:
y = (-4/3)(0) + 4
= 0 + 4
= 4
Write the following expression in exponential form: (2 points) 4.5 × 4.5 × 4.5 × 4.5 × 4.5 × 4.5 × 4.5
Answer:
The answer is [tex]4.5^7[/tex]
Step-by-step explanation:
This is because there are 7 copies of the same number and that means you have to put 7 at the exponential part of it. Then you have to put the original number under the exponential spot. Therefore, the answer is [tex]4.5^7[/tex].
