For f(x)=3x+14, find f(x) when x=−4.
Answers
Answer:
2
Step-by-step explanation:
To evaluate f(x) when x = - 4, substitute x = - 4 into f(x), that is
f(- 4) = 3(- 4) + 14 = - 12 + 14 = 2

calculate the area of this triangle
Answers
Answer: 99 cm
Step-by-step explanation:
To calculate the area of a triangle, we use the formula:
A = H x B divided by 2
If we add our numbers shown, we get:
A = 18 x 11 = 198
198 ÷ 2 = 99
Therefore we get 99 as the answer.
Area = 99 cm

Remy walked to a friend’s house m miles away at an average rate of 4 mph. The m-mile walk home was at only 3 mph, however. Express as a fraction
a) Time Remy spent walking home.
b)Time Remy spent walking.
(Answer both (a) and (b).
Answers
Answer:
a) m/4 miles per hour
b) 7m/12 miles per hour
Step-by-step explanation:
Mathematically, at any point in time;
Time = distance/speed
The distance here at any point is m mph
a) For the time spent walking home
Time = m/4 miles per hour
b) We add the time walking to the friend’s house and the time that it took to walk home
That would be;
m/4 + m/3 = 7m/12 miles per hour

What is the length of the hypotenuse?
C=
yards
HELP
Answers
Answer:
58 yards
Step-by-step explanation:
The Pythagorean Theorem states that:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Where c is the hypotenuse, and a and b are the two legs of the right triangle. Substituting in 40 and 42 for a and b, respectively:
[tex]40^{2} +42^{2} =c^{2}[/tex]
Now, we isolate c:
[tex]c= \sqrt{40^{2} +42^{2} }[/tex]
Therefore, c is equal to 58, so the hypotenuse is 58 yards
Hope this helps!
GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate? (x+5) + (2x-3) (x+5) + (2x-3) 2(x+5)-2(2x-3) 2(x+5)-2(2x-3) (x+5)+(2x-3) (x+5)+(2x-3) 2(x+5)+2(2x-3)
Answers
Answer:
P = 2(x + 5) + 2(2x - 3)
Step-by-step explanation:
GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate?
The shape of the gate is rectangular.
Hence, the Perimeter of a rectangle (the gate) = 2L + 2W
Where :
L = GR = x + 5
W = GP = 2x - 3
Hence,the perimeter of the gate is
P = 2(x + 5) + 2(2x - 3)
Joe is saving for a new online video game. He has some money already in his savings, and he can add $2.50 each week. This relationship is shown in the graph. Write an equation and explain what the slope and the y-intercept mean in this situation?
Answers
Answer: Y=2.50x+b
Step-by-step explanation:
Thats not the whole answer, you didnt attach the graph but what you need to do is find the y-intercept and put that into b and theres your equation. The y-intercept(B) represents the initial money that joe had in his savings the 2.50x part or the slope is the money that he states he can add each week.
Answer:
slope is how much money joe adds to his account savings each week
the y intercept is the money he had before he started waiting
for the equation the slope is $2.50 and the y intercept is where the line hits the y axis but because you don't have a graph I don't know how to help you with this part, maybe someone else can!

it wants us to solve for x and i’m very confused
x= ?
Answers
Answer:
x = 6
Step-by-step explanation:
∡J = ∡K and ∡M = ∡L
because this is an isosceles trapezoid
∡J + ∡M = 180°
because angles at opposite bases are supplementary
then ∡J + ∡M = 180°
∡J = (7x + 2)°
∡M = ∡L = (25x - 14)°
so:
(7x + 2 + 25x - 14)° = 180°
(32x - 12)° = 180°
32x = 180 + 12
32x = 192
x = 6
Answer:
x= 8/9
Step-by-step explanation:
7x + 2 = 25x - 14
-7x -7x
2 = 18x - 14
+14 +14
16 = 18x
