Steps
38 + 7k = 8k + 32
38 + 7k - 38 = 8k + 32 - 38
7k = 8k - 6
7k - 8k = 8k - 6 - 8k
-k = -6
-k/-1 = -6/-1
k = 6
Answer
k = 6

Jane started jogging home from 5 miles away, at a rate of 2 mph. Which equation in slope-intercept form represents Jane's distance from home?
Answer:
10 miles
Step-by-step explanation:
Find the measure of the marked angles.
The measure of the angles is
___ degrees
Answer:
43°
(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]
4x+19 = 6x+7
4x + 19 -7 = 6x
4x +12 = 6x
12 = 6x - 4x
12 = 2x
2x = 12
x = 12/2
x = 6
Now replace the x with 6
(4x+19)°
= (4×6+19)°
= (24+19)°
= 43°
(6x+7)°
= (6×6+7)°
= (36+7)°
= 43°
The measure of the angles is 43 degrees

Write an equation of the line that passes through the point (4, –5) with slope 2.
Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
subtract 8 on both sides
-13 = b
Tom makes $264.00 in 5 days. How much does he make in 2 days?
Answer:
$105.6
Step-by-step explanation:
Tom makes 264 in 5 days.
In one day he makes 52.8.
In two days he makes 105.6.
Answer:
Tom makes $105.60 in 2 days
Step-by-step explanation:
x(5) = $264
Divide both sides by 5: x = 52.8
We get how much he makes in a day.
Multiply by 2: $52.8 * 2
Final answer: $105.6
If I was to sketch the graph of y=4x+2
What would the graph look like?
Would it be a straight line or a curved line?
Where would it cross the y-axis?
What does 4 in 4x tell us?
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 2 ← is in slope- intercept form
Thus its graph is a straight line
crosses the y- axis at (0, 2 ) , that is c = 2
the 4 in 4x is the slope m of the line
I need help with this asap. thank u
Answer:
1/3
Step-by-step explanation:
1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!
[tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex] [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex] [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex] [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.
Graph the linear equation 5x-4y < 20
Answer: (See attached image file)
Step-by-step explanation:
Start by plotting given key featuresBased on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x (5x = 20)(x = 20/5 = 4) (4, 0) We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5) (0, -5) Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.

What type of dilation is formed when the scale factor K is greater than one
Answer:
Enlargement
Step-by-step explanation:
When k > 1, the dilation is an enlargement. When k > 0 and k < 1, the dilation is a reduction. In a dilation, the original figure and its image are similar. The ratio of the side lengths of the image to the corresponding side lengths of the original figure is the scale factor of the dilation.

The acidity in a swimming pool is considered
normal if the average of three pH readings, p, is
defined such that 7.0
Answer:
6.2
Step-by-step explanation:
[tex] \frac{7.2 + 7.6 + x}{3} = 7.0 \\ \frac{14.8 + x}{3} = 7.0 \\ 14.8 + x = 21 \\ x = 21 - 14.8 \\ x = 6.2[/tex]
Jose needs 6.2 lb of organic blueberries to make smoothies. Organic blueberries are on sale for $2.85 per pound. Jose estimates that he will need $12 to buy the 6.2 lb of blueberries. What is Jose’s error?
1. Jose did not make an error. His estimate of $12 is correct.
2. Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
3. Jose incorrectly rounded 6.2 up to 7.
4. Jose incorrectly multiplied 2 and 7. The estimate should be $14.

Correct answer: [tex]b = \frac{2A}{h}[/tex], first option.
[tex]A=\frac{bh}{2}[/tex]
[tex]2*A=\frac{bh}{2}*2[/tex] | multiply both sides by 2, 2's cancel out on the right.
[tex]2A=bh[/tex]
[tex]\frac{2A}{h} =\frac{bh}{h}[/tex] | divide h on both sides, h's cancel out on the right
[tex]b = \frac{2A}{h}[/tex]
