PLEASE HELP <br>Answer: m = 3 <br>3 - y = x + 10<br>Find the slope and y intercept

Kitty [74]

Answer:

slope is -1 and y intercept is -7.

Step-by-step explanation:

3- y = x+10

or, -y = x +10-3

or, -y = x+ 7

or, y = -x-7

comparing with y= mx +c, m= -1, c= -7

Can someone help me with this

Dimas [21]

Answer:

596.0 ft

Step-by-step explanation:

The relationship between the two legs of a right triangle and an acute angle is ...

Tan = Opposite/Adjacent

The height (h) of the lighthouse is the side opposite the angles of elevation. If d is the distance between A and B, we can write two tangent relations:

tan(14°) = h/770

tan(8°) = h/(770 +d)

Equating expressions for h gives ...

770·tan(14°) = (770 +d)·tan(8°)

770(tan(14°) -tan(8°)) = d·tan(8°) . . . . subtract 770·tan(8°)

d = 770·(tan(14°)/tan(8°) -1) . . . . . divide by the coefficient of d

d ≈ 770·(1.7740609 -1) = 596.03

The distance from point A to point B is about 596.0 feet.

Find the missing term of each equivalent ratio. 90:15=_____:7

tatuchka [14]

ANSWER

The missing term is 42.

EXPLANATION.

We want to find the missing term of the equivalent ratio. 90:15=_____:7

Let y be the missing term, then

90:15=y:7

We rewrite as fractions to get;

$\frac{90}{15} = \frac{y}{7}$

Simplify the left ratio:

$\frac{6}{1} = \frac{y}{7}$

Cross multiply:

$6 \times 7 = 1 \times y$

$42 = y$

Therefore the missing term is 42.

SUMMER SCHOOL PLZ HELP

Question 1:
The labeled points are points from the drawing are:
A,B,C,D,E

Question 2:
The intersection of the two lines is a point since the necessary condition for the two lines to intersect is that they should be on the same plane, hence they form a point.
Thus the correct answer is: True

Question 3:
The name for a given line is given from the end points that forms the line. Hence given that the two points forming the line is B and P, the correct answer is option C]

Question 4:
There are 5 letters and you use 2 to name the line, so the number of choices will be given by:
5C2=5!/(2!(5-2)!)
=(5×4×3×2×1)/(2×1×3×2×1)
=10

Question 5:
Collinear points are three or more points which lie on the same single straight line. In our case the points are:
T,X,V
