Which of the following choices is the x intercept of the equation 2y-x=-6
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Given
[tex]2y-x=-6[/tex]
Required
Determine the x intercept
To get the value of x intercept; we simply substitute 0 for y;
i.e. y = 0
[tex]2y-x=-6[/tex] becomes
[tex]2(0)-x=-6[/tex]
[tex]0-x=-6[/tex]
[tex]-x=-6[/tex]
Multiply both sides by -1
[tex]-1 * -x=-6 * -1[/tex]
[tex]x=-6 * -1[/tex]
[tex]x = 6[/tex]
Hence, the x intercept is 6

Answer :
(i) The size of angle x is 58⁰.
(ii) The size of angle y is 70⁰.
Step-by-step explanation :
From the given figure we conclude that:
∠EFB = ∠FGD = x⁰ (corresponding angles are equal)
∠FGD = ∠CGH (vertically opposite angles are equal)
x⁰ = 58⁰
∠FGD = ∠AFG = 58⁰ (alternate angles are equal)
Now we have to calculate the value of 'y'.
As we know that the sum of interior angle of a triangle is equal to 180⁰.
In ΔAGF,
∠GAF + ∠AFG + ∠FGA = 180⁰
52⁰ + 58⁰ + y = 180⁰
110⁰ + y = 180⁰
y = 180⁰ - 110⁰
y = 70⁰
Therefore, the value of size of angle x and angle y is 58⁰ and 70⁰ respectively.
Using the given points, determine Δy.
(-3, -5) and (0, 10)
Δy = 5
Δy = 15
Δy = 13
Δy = 3
Answer:The answer is y=5.

Answer:
1) 5.9
2) 8.1
3) 54
Step-by-step explanation:
A is opposite, so we have sine 36=a/10
sine 36(10)=a
a=5.9
B is adjacent, so we have cosine 36=b/10
cosine 36(20)=b
b=8.1
Angles of a triangle add to 180
we have a angle of 36 and a right angle which is 90
36+90=126
180-126=54

2p+8=20-p what is the value of p??
Answer:
4
Step-by-step explanation:
3p+8=20
3p=12
p=4
Answer:p=4
Step-by-step explanation:
2p+8=-p+20
Step 2: Add p to both sides.
2p+8+p=-p+20+p
3p+8=20
Step 3: Subtract 8 from both sides.
3p+8-8=20-8
3p=12
Step 4: Divide both sides by 3.
3p/3=12/3
p=4

Celia uses 30% of the money in her savings account to buy a present for her grandmother on her 80th birthday. The present costs $45. The bar model represents this situation. What is the value of each section of the bar, and how much money did Celia originally have in her savings account? A bar model divided into ten equal parts. The first 3 parts from the left each say fifteen. These 3 parts altogether are labeled forty-five. A number line appears above the bar model. It has eleven tick marks that divide it into ten parts, with each part the same width as a part in the bar model. The tick marks go from zero percent to one hundred percent in increments of ten. A Each section represents $13.50. Celia originally had $135 in her account. B Each section represents $15. Celia originally had $150 in her account. C Each section represents $30. Celia originally had $300 in her account. D Each section represents $45. Celia originally had $450 in her account.
Answer:

Angela is following this recipe to make biscuits.
Angela uses 1.8 l of syrup.
How much margarine is needed in kg?
Recipe: Makes 10 biscuits
150 g margarine
180 g sugar
225 ml syrup
225 g oats
40 g sultanas
Asapppp
Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed [tex]\frac{1.5L}{0.225L}\times 150 g=1000g[/tex] of margarine
Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.

What is the solution to -2(8x – 4)< 2x + 5?
Ox>
Ox<
O x > 6
O x<6
Answer:
x> 1/6
Step-by-step explanation:
-2(8x – 4)< 2x + 5
Distribute
-16x +8 < 2x+5
Add 16x to each side
-16x +8+16x < 2x+16x+5
8 < 18x+5
Subtract 5 from each side
8-5 < 18x
3 < 18x
Divide each side by 18
3/18 < 18x/18
1/6 < x
Answer:
[tex]x > \frac{1}{6} [/tex]
First answer is correct.
Step-by-step explanation:
[tex] - 2(8 x - 4) < 2x + 5 \\ - 16x + 8 < 2x + 5 \\ - 16x - 2x < - 8 + 5 \\ - 18x < - 3 \\ \frac{ - 18x}{ - 18} < \frac{ - 3}{ - 18} \\ x > \frac{1}{6} [/tex]

Work out the size of the interior angle of a regular 16-sided polygon
Answer:
157.5°
Step-by-step explanation:
Total size of interior angles=(2n-4)90°
(2x16-4)90= 2520
size of one interior angle= (2n-4)90°/n
2520/16
Answer= 157.5°
NB n is the number of sides
The size of the interior angle of a regular 16-sided polygon would be 157.5 degrees.
A regular polygon is a flat shape whose sides are all equal and whose angles are all equal.
The formula for finding the sum of the measure of the interior angles is,
S = (n - 2) × 180.
We have to give that,
A regular-sided polygon has 16 sides.
Using the formula for a regular polygon of n sides would be,
Each interior angle = [tex]\dfrac{(2n - 4) \times 90 deg}{n}[/tex]
Here, we have the sides of the regular polygon;
n = 16
Hence substitute n = 16 in above formula,
Each interior angle = [tex]\dfrac{(2n - 4) \times 90 deg}{n}[/tex]
[tex]= \dfrac{(2\times 16 - 4) \times 90 deg}{16}[/tex]
[tex]= \dfrac{(28) \times 90 deg}{16}[/tex]
[tex]= 157.5 \ \text{degree}[/tex]
Therefore, The size of the interior angle would be, 157.5 degrees.

Al llegar al hotel nos an dado un mapa con los lugares de la ciudad nos dijieron que 5 cm del mapa que representaban 600 metros de la realidad hoy queremos ir a un par que que se encuentra a 8 cm del hotel en el mapa. ¿A qué distancia del hotel está la pareja?
Respuesta: 960m
Explicación paso a paso:
Dado que:
5 cm en el mapa equivale a 600 m en tierra Por lo tanto,
8 cm en el mapa será equivalente a:
5 cm en el mapa - - - - - -> 600 m en el suelo 8cm - - - - - - -> y metros en el suelo
Usando la multiplicación cruzada
y × 5 = 8 × 600
5y = 4800 Luego,
y = 4800/5
y = 960m
Por lo tanto, 8 cm en el mapa serán 960 m en realidad.
