y^2 -1y + 8y - 8
y^2 +7y - 8
Answer:
y²+7y-8
Explanation:
y times y equals y²
y times -1 equals -1y
8 times y equals 8y
8 times -1 equals -8
-1y combines with 8y to make 7y

In triangle JKL, if angle J is seven less than angle L and angle K is 21 less than twice angle L, find the measure of each angle
Answer:
j=45 k=83 L=52
Step-by-step explanation:
j=x-7
k=2x-21
L=x
x-7+2x-21+x=180
4x-28=180
4x=208
x=52
The measure of the angles are; J = 48, K = 57 and L = 75
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
In order to determine the measure of these angles, we have to set J as x. then find the measure of all of these angles.
J = x
K = x + 9
L = 2x - 21
Now, we can add them all together and set equal to 180;
x + x + 9 + 2x - 21 = 180
4x - 12 = 180
4x = 192
x = 48
Now that we have;
J = x = 48
K = x + 9 = 48 + 9 = 57
L = 2x - 21 = 2(48) - 21 = 96 - 21
L = 75
Hence, The measure of the angles are; J = 48, K = 57 and L = 75

(X,Y) aka (horizontal, vertical)
Answer:
(-4, -1), (0, 2), (4, 5)
Step-by-step explanation:
(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.
(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.
(0, 2): At 0, the graph lies on 2.
(4, 5): At 4 on the x-axis, the graph lies at height 5.
(2, 0): The graph is already at height 3.5 when at length 2.

The engines of a plane are pushing it due west at a rate of 250 mph and the wind is blowing from the southwest at a rate of 25 mph. find the direction of the plane
Answer:
84.26° in the south west direction.
Step-by-step explanation:
I've attached an image showing the triangle formed by the motion of the plane and the wind.
I've depicted the plane being pushed west and the wind moving south west.
Thus, the direction of motion of the plane will be angle θ.
Using trigonometric ratios;
25/250 = cos θ
cos θ = 0.1
θ = cos^(-1) 0.1
θ = 84.26°
Thus will be in the south west direction.

A bus driver drives 6 miles a day how many miles does the bus driver drive in 5 days?
Answer:
The bus driver drives 30 miles in 5 days.
Step-by-step explanation:
Hi,
You can use the rule of three to solve this problem.
For the first step, we need to analyze the information given:
[tex]6 (miles) = 1 (day)[/tex]
and we want to know how much miles the bus driver drives in 5 days:
[tex]x (miles) = 5 (day)[/tex]
Thus,
[tex]6 (miles) = 1 (day)[/tex] ... (1)
[tex]x (miles) = 5 (day)[/tex] ... (2)
Now, multiplying in a cross and we have:
[tex]x *1 = 5*6 \\ x = 30[/tex]
Lastly, replacing the value of x in (2):
[tex]30 (miles) = 5 (day)[/tex]
and this is the answer

Which graph represents the function?
f(x)=2x√+1
Using translation concepts, it is found that the fourth graph(right graph of the bottom row) represents the function f(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is [tex]f(x) = \sqrt{x}[/tex], which has vertex at the origin.
The translated function in this problem is [tex]f(x) = 2\sqrt{x + 1}[/tex], which was vertically strecthed by a factor of 2 units(which does not change the vertex), and shifted left 1 unit, which means that the vertex is now at (0,-1).
Hence, the fourth graph(right graph of the bottom row) represents the function f(x).

what is the slope of a line that has a y-intercept but no x intercept
Answer:
The slope of a line that has a y-intercept but no x-intercept will be zero.
Step-by-step explanation:
If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.
If a line does not have an x-intercept, it means it would never intersect the x-axis.
Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.
For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.
Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.

If 76g of sodium reacts with chlorine to produce 214g of sodium chloride, how many grams of chlorine reacted?
need help
Answer:
138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Step-by-step explanation:
We are given:
Grams of Sodium = 76 g
Grams of Sodium Chloride = 214 g
We need to find how many grams of chlorine required to produce 214 g of sodium chloride
The equation will be:
[tex]Na \ + \ Cl \ -> NaCl\\76\ g \ \ \ x \ g \ \ \ \ \ \ \ \ 214 g[/tex]
We can write: 76 (g) + x (g)=214 (g)
Solving and finding value of x
x =214-76
x=138 g
So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
