Answer:
f(4) = -28
Step-by-step explanation:
f(x) = -[tex]x^{2}[/tex] - 6x + 12
f(4) = -[tex]4^{2}[/tex] - 6(4) + 12
f(4) = -16 - 24 + 12
f(4) = -40 + 12
f(4) = -28
2. Solve 8(4-x) = 10
[tex] x = 2 \frac{3}{4} [/tex]
Step-by-step explanation:
[tex]8(4 - x) = 10[/tex]
Expand :
8(4-x) = 32-8x
[tex]32 - 8x = 10[/tex]
Collect like terms and simplify
[tex] - 8x = 10 - 32 \\ - 8x = - 22[/tex]
Divide through by -8
[tex] \frac{ - 8x}{ - 8} = \frac{ - 22}{ - 8} [/tex]
Simplify
[tex]x = 2 \frac{6}{8} \\ \\ x = 2 \frac{3}{4} [/tex]
Answer:
x=2.75. 8(4-2.75)=8(1.25)=10.

3/4 (6x + 1) - 3x = 1/4 (2x - 1)
3/4 (6x + 1) - 3x = 1/4 (2x - 1) . The purpose of this question is to solve for x.
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]
Given that:
3/4 (6x + 1) - 3x = 1/4 (2x - 1)When calculating algebraic expression, we take note of integers in bracket first, then we collect the like terms in order to find the value of x.
[tex]\mathbf{\dfrac{3}{4} (6x + 1) - 3x =\dfrac{1}{4} (2x - 1) }[/tex]
Let's multiply both sides by 4 to eliminate the fraction.
[tex]\mathbf{(\dfrac{3}{4} \times 4) (6x + 1) - 3x =(\dfrac{1}{4} \times 4 ) (2x - 1) }[/tex]
[tex]\mathbf{(3) (6x + 1) - 3x =(1 ) (2x - 1) }[/tex]
Open brackets;18x + 3 - 3x = 2x - 1
By rearrangement;18x - 3x + 3 = 2x - 1
15x + 3 = 2x - 1
Collect like terms15x - 2x = - 3 - 1
13x = - 4
Divide both sides by 13[tex]\mathbf{\dfrac{13x}{13} = \dfrac{-4}{13}}[/tex]
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]

If a coordinate is on the x or y axis then it is NOT in a quadrant. True or False?
Answer:
True
Step-by-step explanation:
For something to be in a quadrant, the y and x coordinate have to be greater than 0. If a coordinate is on the y-axis or x-axis either x or y coordinate will be 0. That is why it is not in a quadrant.
Make a table of ordered pairs for the equation.
y=2×+1

Andrew solved the following inequality, and his work is shown below:
−4(x + 8) + 25 ≤ −2 + 1(x − 50)
−4x − 32 + 25 ≤ −2 + 1x − 50
−4x − 7 ≤ 1x − 52
−5x ≤ −45
x ≤ 9
What mistake did Andrew make in solving the inequality? (2 points)
Question 3 options:
1)
He subtracted 1x from both sides when he should have added 4x.
2)
When dividing by −5, he did not change the ≤ to ≥.
3)
He added 7 to both sides when he should have added 52.
4)
He did not make a mistake.

Answer: -4
Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.

Answer:
x. a.
y. b
z. c.
Step-by-step explanation:
So from the middle column, we know that each row or colum must be -12 because 1 - 8 - 5. x + 1 - 12 should be = - 12, so x -11 = 12, so x = -1
For z, - 12 + 3 + z = -12, so z = -3
For y, y - 5 + z = -12, but we know z so we can plug in -3:
y - 5 - 3 = - 12
y - 8 = -12
so y must be -4
What is the measure in degrees of the smaller of the angles formed by the hands of a clock at 7:48?
Answer:
So the measure in degrees of the smaller angle formed by the hands of the clock at 7:48 is 24 degrees
Step-by-step explanation:
At 7:48 , we have two angles formed
One formed by the hour and the other formed by the minute hand
The angle formed by the hour hand will be;
7/12 * 360 = 210 degrees
Let’s now go for the minutes hand
mathematically;
60 minutes = 360 degrees
So 48 minutes will be ;
Recall;
there are 12 hours on a clock, so each hour will be 30 degrees
So the angle for 48 minutes will be;
48/60 * 30 = 24 degrees
