Using graph, the value of g(x) = 8 and the y- intercept at the point (0,-1).
What is graph?A graph is a "mathematical representation of a network and it describes relationship between lines and points".
According to the question,
f(x) = [tex]10^x[/tex]
g(x) = -4f(x) +12
g(x) = -4 (10ˣ) +12
The graph intersect at y-axis then x-coordinate should be zero.
Let take any two points on y-axis (0, 1) and substitute g(0) = -4 (10⁰) + 12
= 8
Hence, the value of g(x) = 8 and the y- intercept at the point (0,-1).

which of the ordered pairs is a solution of the following equation
5x-2y=20
Answers
We want to see which ordered pairs are a solution of the equation:
5x - 2y = 20
The ordered pairs are not given, so I will give a general answer, finding the general form of all the ordered pairs that are solutions.
We start with the equation:
5x - 2y = 20
First, we need to isolate one of the variables, let's isolate y.
2y = 5x - 20
y = (5/2)*x - 20/2
Then we get:
y = (5/2)*x - 10
From this, all the ordered pairs (x, y) that are solutions of this equation are given by:
(x, (5/2)*x - 10)
Then to get the points we just need to replace the "x" with numbers, for example for x = 0 we get the solution:
(0, (5/2)*0 - 10) = (0, -10)
For x = 1 we get the solution:
(1, (5/2)*1 - 10) = (1, -15/2)
And so on.

what you find 420% of 85 what are you looking for?
Answers
Answer:
420% of 85 = 357
Step-by-step explanation:
85/x=100/420
(85/x)*x=(100/420)*x - we multiply both sides of the equation by x
85=0.23809523809524*x - we divide both sides of the equation by (0.23809523809524) to get x
85/0.23809523809524=x

A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.
Answers
Answer:
Yes, Rain is correct
238.5 square inches
Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the net attached:
Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)
Surface area = 223.5 in²
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

Sam has a total of 43 quarters and nickels in her purse. If her change is worth $7.75, how many nickels and how many quarters does Sam have?
Warning: This is Algebra 1
Answers
Answer:
i need help with this too\
Step-by-step explanation:
Let n=the number of nickels
q+n=43 This equations represents the total number of coins.
0.25q+0.05n=7.75 This equations represents her change totaling to $7.75.
Multiply the second equation by 100 to simplify the arithmetic.
q+n=43
25q+5n=775 Multiply the first equation by -5.
-5q-5n=-215
25q+5n=775 Add the two equation in which the n variable gets eliminated.
20q=560 Divide both sides by 20.
q=28 Substitute q=28 into the first equation and solve for n.
28+n=43
-28 -28
n=15 Therefore, she has 28 quarters and 15 nickels in her purse.

In ΔWXY, y = 88 cm, x = 85 cm and ∠X=70°. Find all possible values of ∠Y, to the nearest 10th of a degree.
Answers
Answer:
All possible values of ∠Y are 76.6° and 103.4°
Step-by-step explanation:
In Δ WXY
∵ x is the opposite side of ∠X
∵ y is the opposite side of ∠Y
→ By using the sine rule
∴ [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]
∵ x = 85 and y = 88
∴ m∠X = 70°
→ Substitute them in the rule above
∴ [tex]\frac{85}{sin(70)}[/tex] = [tex]\frac{88}{sin(Y)}[/tex]
→ By using the cross multiplication
∴ 85 × sin(Y) = 88 × sin(70)
→ Divide both sides by 85
∴ sin(Y) = 0.9728582427
∴ m∠Y = [tex]sin^{-1}[/tex](0.9728582427)
∴ m∠Y = 76.62037845
→ Round it to the nearest tenth
∴ m∠Y = 76.6°
→ The other value of ∠Y is the obtuse angle supplement of ∠Y
∴ m∠Y = 180 - 76.6
∴ m∠Y = 103.4°
∴ All possible values of ∠Y are 76.6° and 103.4°
